    Hello, my name is Darren, aka Dr. Sci-Fi. I’ve been a fan of Star Wars and Science Fiction my entire life. I’ve also enjoyed building my fandom with props, armor, and suits.

    Previously, my largest project was a 1/3rd scale Electra 10 airplane. The kind Amelia Airheart flew. It sat 12’ long and 17 ft wide, had to be modular to fit through the doors and secured safely from the ceiling. If you want to read more about it, my building blog is http://thecardboardworkshop.wordpress.com. Or view my stormtrooper blog at http://drscifi.com/stormtrooper

    I am building a 1:1 scale K-2SO Puppet. He began his life as a suit build which you can read about below but now is progressing as a puppet I will operate connected to my hands, feet and chest.
    I'll be keeping this first post updated with the latest content but enjoy my build blog and progress.

    -Darren

    Re: ROGUE ONE K-2SO Suit Build

    ------UPDATE-----12/11/2016-----
    Shifting plans from a suit to a puppet. More posts below.


    Now I am about to tackle my most ambitious project yet. A K-2SO droid from Rogue One: A Star Wars Story.
    I hope to catalog my build process here on the RPF and welcome your encouragement and support. My time table is to be done by the premieres in mid December. 170 days from this posting.

    27938979046_54952f5dc3_z.jpg

    I first had this idea a few months ago, and am now in the R&D phase. Gathering information, costs, parts, materials, fabrication methods. There is a lot to do and very little to go on so far.
    So an upfront warning, I will be posting pictures here I find from the internet as I source K2’s look. I don’t want to spoil the movie for myself but I ultimately need the info on this droid. So if you don’t want to see any images from Rouge One turn back now until after December 2016.


    K2’s original design was a spin off from another project I had in R&D, an IG-88 puppet. My original plans were to have a K2 puppet a foot in front of me that was attached in a similar manner to how they did C-3PO in The Phantom Menace. But as I talked to costuming friends I realized the best option would be to do a K2 suit. Which of course had it’s own enormous challenges. My ultimate goal is to take K2 to a Rouge One premier in December if I can. This guided me down the path of Plan B, a suit. I’ll be posting several shots from my K2 notebook, it’s where I sketch ideas as my mind turns this droid over and over.

    "Mapping out the individual components for putting the suit on"

    27871870752_ba3a74c1cd_c.jpg
    "Mock up of fitting inside suit, before full front image of K2 surfaced. K2 was 8.5' tall."


    I begin setting up a modest budget of $500 dollars for parts and tools. I had just finished a GONK droid for around $250 but he needed specific parts to get the look I wanted. I may go beyond this estimate but it’s good to have limitations, they expand what you will try to make it happen.


    One of the trickiest parts of the build is the very limited or non existent images of K-2SO. I’m hoping for a few more trailers and images but at least have a bit to start with. I really wish I knew his approximate hight as that would help me scale him, but I’ll get into that later.


    Some key requirements I have for the suit are:
    • That I can stand in it for long periods of time.
    • Walk comfortably.
    • Have good visibility.
    • Be safe if I fall over.


    From the first R1 trailer it appears that K2 is much taller than the average human. This makes the project even possible. As the real K2 never existed physically. He is a completely CG character. His legs are very very long, and his arms are elongated too. I decided to go with stilts for the legs and arm extensions for the forearms.

    Once Entertainment Weekly released a full frontal shot of K2 I began to envision how I would fit inside the droid. My original plan was to have my entire upper body in his torso and use a camera to see. The head would be a puppet above my own. There is a 35% chance I will still go this route, but I will need to do some full size cardboard mock ups to confirm the direction I want to go in.

    27697643525_c99cddedcb_c.jpg
    "When you do stand next to someone i'll be ready K2!"

    I took a picture of myself in my Stormtrooper under armor and using my 6’ hight for scale adjusted K2’s proportions to fit around my body. I do need to fit into the thing, and I can't move my hips or where my knees are. Talking with the twitter user @KayTooEsso led me to believe his hight may be 6.75’ high. With trying to make myself fit inside him I had to make K2 around 7.5’ high to fit. And that is with my head being inside a helmet for his head. Not my first choice but again, the cardboard mockup will be my deciding factor.

    I plan to build K2 out of foam. I purchased a foamsmithing guide from Punished Props @chinbeard. This will be my first foray into foam, having worked extensively in cardboard and ABS plastic in the past. 1/3rd scale Electra 10's and Stormtrooper Armor respectively. But I’m confident I can do it.
    View attachment 639103

    I am searching all over the internet for a pair of Marshalltown SKY2115 Skywalker stilts. They are the only ones I can find that look like a foot instead of two poles and a plate. But Marshalltown has discontinued their sale. I hope they won't eat up too much of my budget.
    27360698953_3b8d1f3eb2.jpg

    Head:
    In the recent EW images it seems K2’s eyes have a bright ring around their edges with a soft glow in the middle. Very cool. Will need to figure out how to do this with LED’s. I have yet to determine if his head will be on my head, or above it. If I do wear it like a helmet I will try to cheat my neck by having a thin ribbed tube over the front which is the proper width of his neck and then have my neck in black cloth behind that. Giving the illusion of a thinner neck. But we will see.
    If the head is a puppet I want to try to put my 170* back up camera in his vocabulator (mouth) to get a high view of where I am looking and walking.
    27857609096_eee3a64d4a_z.jpg

    Torso:
    Inside the torso I would have my monitor from the back up camera. My arms would also go up to K2’s elbows. So my wrist joint is his elbow joint. This will work well and is the most thought out part of the build so far.
    I plan on using a backpack frame to support the torso/head on my person. All of these pieces will be foam for tooling and weight. I’m thinking of a double cup method to secure the torso to my backpack frame. This would let it be automatically guided into the cups and secured with rare earth magnets. (REM) I want to be able to don as much of this suit as I can by myself.
    27694019740_3f693c51f2_b.jpg
    "Two (wrist) elbow ideas, going with the wrist elbow instead of the gear elbow"

    I also came across a rendering of K2’s back which has a Stormtrooper feel with the cog and bars but with some cool antenna. This image alone will make it much easier to complete his torso design. If it is accurate.
    27380013145_bc003aaf9e_c.jpg
    "K2's back"

    Arms:
    I plan on making a (wrist) brace for me that I can mount into his elbow. I will also run wires down the forearm to his hands so I can close his fingers with my fingers. This is a simple technique used in many puppet arms. I can cheat making a right angle with my arms by coming through the lower part of his shoulder joint.


    Legs:
    For the legs I plan on wearing the SKY2115 stilts. This number stands for the 2.1 version with a minimum 15” foot hight. But I can extend that up to 23” if I need to. My foot will be half way down his lower leg and the stilt foot will be covered with a shell to match K2’s width and look.
    27896218061_3143d3cd9f_c.jpg
    "Minimizing the look of a real foot on a stilt is a top priority. This image looks at ways to hide my toe, but now seeing K2's legs I will simply make an oval around my entire foot."


    Once I have my stilts I will be practicing with them every week to be comfortable enough using them in the suit. I may also build a solid rod into the right arm so that if I begin to fall I can catch myself, probably sacrificing the hand.

    Next tasks:

    • So for now I am continuing to look for my stilts.
    • Determine K-2SO’s hight and other dimensions.
    • Decide to use his head as a puppet or helmet.


    Please feel free to comment with any info you have found on K2. I’m looking forward to the next 170 days.

    ------------------------------------------------------------

    Today was a milestone. I found my STILTS!!!!!!
    Marshalltown Skywalker 2.1 series, which expand between18" to 30". I'm planning on having them at 2 feet (24") for K-2SO. These have been very difficult to find for something besides full cost. Should arrive by July 21st.

    27360698953_3b8d1f3eb2.jpg

    This weekend is Star Wars Celebration Europe and I really really hope we get more of K-2SO. If anyone comes across images, specifications or merchandise please post it here on this forum for my research. Perhaps I will discover his elusive hight.
    celebration.jpg

    Once I have my stilts I will start practicing and constructing the legs out of cardboard for a test run. If that is successful I'll begin foam fabrication.
    154 Days until Rogue One! Let's do this!

    Re: ROGUE ONE K-2SO Suit Build

    We have more pictures! This past week was Star Wars Celebration Europe in London. We got a great sizzle reel of behind the scenes Rouge One footage.


    But this image is what caught my attention. This is Alan Tudyk in his motion capture suit with K-2SO imposed over him. He is mostly blocked but knowing he is 6' tall and has a helmet on I estimate K2 to be between 7' and 7' 2". Alan also says that K2 is seven feet tall at the Rouge One panel. Now that statement sounds like a nice rounding of the hight so I'm fine making him a few inches over 7 feet.

    28252279911_528588acec_c.jpg

    So with my new calculations I scaled the Entertainment Weekly image to a hight of 7' 2". I then adjusted my profile into a K2 that is 7' 7" tall. I also am moving towards building it with the puppet head instead of the helmet head. This means i'll need to scrunch my head down a little bit. Cardboard prototype will reveal which course I take.

    28254927282_a228974912_b.jpg

    In researching K2's neck I came across the "JFOTO Zifon Remote Control Automatic Motorized Rotating Stabilizer Head Mount Pan Tilt + Wireless Remote Control" on Amazon. This will allow me to keep the small keychain remote under my right thumb. Mounted at the top of his neck in the lower part of his head I can make him look side to side and up and down. The motor movement is a tad on the slow sign but I don't know if i'll find something that satisfies all of my requirements. Battery Powered, One Handed controls, Pan and Tilt.

    41xyuJUeHaL._SX425_.jpg

    Here is another beautiful image from Celebration. I love the weathering on the imperial logo.

    28252321021_ed65cba799_c.jpg

    MY STILTS ARRIVED!
    My Marshalltown Skywalker 2.1 stilts are here. I tried them on at their lowest hight and they work great. This adds 21" to my foot hight.
    The next step will be mocking up both legs in cardboard, if that test is successful there is no turning back.

    28555906145_2d7690db44_c.jpg

    Now I just want to know what K-2SO sounds like. Alan has described him sounding like an old human, very honest and stubborn. I think I can portray that. :)
    143 Days until the Rogue One Premier!

    Re: ROGUE ONE K-2SO Suit Build

    After a long autumn, I've taken the K-2S0 project in a new direction. Instead of a wearable suit he will be a puppet suspended in front of me as I wear my Imperial Officer uniform.
    I've cut the PVC to length for his skeleton. The joints are spider-joints from http://www.spiderhillpropworks.com/Single-Spine-Body-Hardware-Kit_p_19.html They sell a whole kit for a Halloween mannequin display with all of the joints you need.
    I pulled many of my dimensions right off of the K-2S0 black series figure. Making a 1"=1' scale ruler with "inch" marks.
    31442823002_243436d02c_z.jpg 31217142970_28e8f47c4a_z.jpg

    For scale, the shoulder cross-bar stands 6' off the ground when he is upright.
    31555266236_fb4ae1d625_c.jpg

    I added 1-1/2" neoprene washers into the joints so I could move them with friction. These covered the locking teeth in the joints.
    31217126700_b00b05f515_z.jpg 31443034072_3eeaa0e216_z.jpg

    Next step will be to complete the feet and torso mount. I want to complete a lot of testing while he is just bones, before covering him in EVA foam.

    I purchased a tactical OPS chest harness to support the puppet weight under my officers uniform.
    30747988004_fbdeb75778_z.jpg

    I plan to post much more frequently here on the RPF as I continue this build.
    Enjoy and happy making.

    What?! Two posts in two days? What is this madness?

    Well progress is moving swiftly on the K-2S0 puppet. I made another run to Lowes during my lunch break and picked up some needed PVC couplers.


    I got a new T for the hips. It is 1-1/4" on the long edge and 1" on the middle edge so it fits my existing 1" pipe but holds the full hip pieces so I have less reductions to do. The hip slip rings are 1-1/4".
    [​IMG]

    Old and new. These end caps will reach the edges of his hips at 15" across. I may cheat them out a little more but the easy thing is I just need to add longer hip PVC, easy enough if needed.
    [​IMG]

    Cut through 2" pipe with my pipe cutter, who says it can only handle 42mm!
    [​IMG]

    Adapted the 1" cross bar to a 2" 45* coupler for the neck. This pipe will join with the pan/tilt head at the base of his head.
    [​IMG]

    Cut some more 1-1/4" pipe to reduce the slip rings down to the 1" skeleton pieces.
    [​IMG]

    All of these joints are friction and tape held for now. WIll glue and screw them together when the dimensions are finalized.
    I used my now extra hip "T" to make a connector spot for the harness on his back. I may go this route, but am still figuring out how the back is joined to my harness, so
    i kept the original lower spine.
    [​IMG]

    Fully assembled and very tall. Just over 7'. Also note that the fore arms are longer than where his wrists are. The pipe extends to where his fingers will start.
    [​IMG]

    More detail on the center connections. Right now the spine joint is locked with it's teeth.
    [​IMG]

    I sat him up to see the harness conneciton spot.
    [​IMG]

    This is a temporary hold to keep the shoulder slip rings on while I do testing. I will use a long screw to secure a flat plate over this end cap to keep the slip ring in place.
    [​IMG]

    That's right! K-2S0 folds up for easy storage. For now.
    [​IMG]

    Here is some scale. I stand at 6'. The bend in his neck is exactly 6' 3" off the ground.
    [​IMG]

    Testing standing in puppeteering position. The harness connection will happen at the top of my chest. He is VERY tall!
    My right hand is where the elbow puppet handles will be. My left hand is just supporting his weight for now.
    [​IMG]

    Next step is to still figure out the harness connection and rigidity. Complete the feet and their attachments to my boots.
    I also need to design how he will come apart for transport.

    Thank you everyone for your encouragement. I can't wait to see him on screen this Thursday!

    Ha. Yeah won't make it by the premier. But can still troop around with him and take him to cons. I'm noting who has other RO characters in my area.

    Another day, another run to Home Depot for parts. Instead of using a 6" x 15" plywood piece for the main chest support I went with this 12" T plate. I curved it around my stomach and placed it inside the velcro pouch that makes up the front of the military harness.

    [​IMG]

    A * with a 45* coupler will be bolted to this section of the support.
    [​IMG]

    I plan to attach webbing or another strong (non stretching) material to the top of the "T" to my shoulder clips. This will hold the T close to my chest and keep it steady as K-2SO tries to pull me over.
    [​IMG]

    Marked and drilled 3/16" holes for the connecting bolts. I need something that will sit flush on the inside against my chest but not stick out too much into my costume.
    [​IMG]



    I'm moving the spine spider joint and replacing it with a solid 1" PVC pipe.
    [​IMG]

    The spider joint now replaces the top 45* connector. This will let me adjust the angle using the joint teeth when I am all suited up. I have a feeling this will help set K-2SO's spine to be level once he is connected.
    [​IMG]

    I think I need to invest in a dedicated 7/16th hex driver. I will be adjusting these spider joints several times while making K-2SO and while suited up.
    [​IMG]


    I reworked the neck to change it from a 2" pipe to a 1-1/4" pipe. This placed the 45* connector closer to the top chest brace. I like the thickness of this pipe better as I can add strips to it to create the droid detail in his neck. I need to chop the end at a 45* cut to mount the pan/tilt unit. Fortunately this has a standard tripod mounting thread on the bottom that I can imbed a male bolt into the pvc to make a strong connection.
    [​IMG]

    The last thing I did tonight was added some small bungee cords to the knees. The goal is to make let the leg return to a upright position easier. I still need to put a piece of plastic in to keep the knee from bending backward. I also need to remember to situate the spider joints with the adjust nut on the outside edge before glueing/* them to the pvc pipe. I plan to add several "adjustment' ports for my 7/16th inch hex driver.
    [​IMG]

    If I can get a hold of my father-in-laws chop saw I may be able to cut some of the pvc the way I need it tomorrow. Sure wish I had a full shop with a band saw.

    After Christmas I plan to order all of the foam form TNT cosplay.

    Got a hold of a fine toothed hack saw and vice grip. This let me cut the 45* angle on the neck pipe. I marked the edges of the cut with blue tape, still eyeballing the angle.

    [​IMG]

    The hacksaw made quick work of the cut.
    [​IMG]

    Held the pipe up to a 45* angle, just about right. Close enough ;)
    [​IMG]

    Temporarily taped the pan/tilt head to the neck pipe. I can trim it shorter if needed but keeping lots of pieces temp taped for now.
    [​IMG]

    I'll use the tripod thread to secure the pan/tilt once I buy the bolt.
    [​IMG]


    Did a photoshop mockup of the top torso pieces with my black series K-2SO overlaid. There is a little distortion from the picture and distances but it's pretty spot on. I may need to drop the base of the neck to overlay the shoulder cross piece and extend the biceps longer to keep the shoulder swivel in the proper place. The pan/tilt is shown where I plan on keeping it. Inside the head giving the skull a central pivot point.
    [​IMG]

    Since I don't plan on the wrists pivoting I have the forearm extending into them for stability. The finger control wires will come out of the arm shaft to articulate a grip motion.

    Can't wait to work on the next piece.

    Merry Christmas to you all. I've been pouring over the Rogue One Visual Dictionary which has some great shots of K-2SO. I also had a chance to finish the neck mount.

    While doing some last minute shopping I found a $4 selfie-stick which had an adjustable camera thread on top. This had everything I wanted in a selfie-stick!
    [​IMG]

    I could use the arm of the stick to secure it in place and the camera thread would securely hold the pan/tilt head to the neck.
    [​IMG]

    Measured the selfie head onto the 45* cut I made a few days ago.
    [​IMG]

    Used a hack saw and a big bit to cut out the sides. Made a little cardboard filler piece.
    [​IMG]

    The selfie head fit nice and snug in the pvc pipe. The cardboard again is just filler. Placed some clear pacing tape over it all.
    [​IMG]

    The secured pan/tilt head. I fortunately can twist it on without having to hold the locking wheel on the selfie head, as that is now inaccessible.
    [​IMG]

    I've also ordered my diving fins for the feet connections. These should fit over my Imperial Officer boots. I plan to cut them into a sort of "S" pattern, mirrored to place K-2SO's feet farther apart than my own.
    [​IMG]

    I practiced walking with an elongated foot with a simple board taped to my shoe. I will need to definitely practice a lot to have a more natural gait. But having a robot walk will help. I just need to go slow.
    [​IMG]

    I am happy with the progress so far and soon will have all the pieces needed to mount the skeleton for walking trials. I want to get very comfortable with this step before adding any skin.
    I've also thought more about the joints and i'm for sure including the ankle joint. It will be needed more when one leg is placed ahead of the other. And I will need to reverse the knee mini bungee cords. I want that joint to pull into a bent configuration naturally. So when I take a steep his knee raises up with little effort.

    Also, I post a little more frequently on my instagram account. @drscifiprops Then compile those shots into updates here.

    More to design, and I still need to place my big foam order.
    See you all in the new year.

    Cost and time. I ended up selling my stilts for some cash a few months back. And overall K2 would be 8-9 feet tall as a suit to fit inside.
    I use many of the same principles for the puppet. And I may make a suit as version 2. But for a first build I think going the puppet route is better. 1:1 scale.
    Perhaps I'll develop a puppet/suit hybrid.

    More plans, more progress. My diving fins have arrived, they reach a good distance out from my feet. With K-2SO's stance being wider than I thought I've added pipe to his hips to make the center of his feet sit 18" apart, which will flex between 18" and 22". I'll make a false boot shaft out of foam to blend in my officer uniform.
    31828059322_8416262288_c.jpg

    Practice, practice, practice. The cool thing is in walking with these on the timing of K2's legs an mine is staggered, which I think will help him appear less "puppeted".
    31915764976_8cea51ea17_c.jpg

    The foot * will bolt right onto the fin, but the fin will be trimmed to only connect my foot to K2.
    31805190982_4d3019bec0_c.jpg

    Working on the foot profile using a variety of images including the Star Wars: Rogue One Visual Dictionary. He has BIG feet. I'm planning on having the toe hinge.
    31938978816_fdfc1ae40d_c.jpg

    Many pieces have been ordered, deliveries over the next week.
    31916123236_15244e61c8_c.jpg

    I cut a notch in a 45* to move the neck connection to tangent directly into the shoulder bar.
    31805469212_fed4b9e08b_c.jpg

    This keeps the neck pipe in line where it should be, coming directly out of the shoulder line at 45*.
    31143994943_2394ea7e1f_c.jpg

    One of the last steps will be trimming the bottom of the neck pipe to make it the proper length, but for now he is standing at 7' 2", right on target. (Stay on target).
    31916123716_362d55e5ff_c.jpg

    Acquired 10-24 3/4" bolts for the harness flanges and the feet flanges. Also lock nuts to keep it locked up.
    31938127346_7427260b38_c.jpg

    Tests show I need to add more reenforcement to the harness connector. So I got another 1" T joint and now have two pipes coming out of the harness to K-2.
    31976045425_143bd38c08_c.jpg [

    Harness connection bolted to metal T.
    31938127166_f6a4254d47_c.jpg

    This will have to support all of K-2SO's weight. I still need to put another bar between the shoulder straps to hold this perpendicular to my torso.
    31975157285_fd4effd20a_c.jpg

    Plans for the elbow and knee joints. Layers of foam with cloth covering the void in the center third. My 2" mirrors arrived to create the hollow illusion of the joints.
    31938978966_27884ce150_c.jpg

    Standing with K-2SO. Right now the weight is on his feet and on the harness. A new thing I need to dial in is his distance from me. His elbow points are a little far for my arms to reach, so I need to either extend my control handles past his elbows or bring his body closer to me. I really need to get some of these joints glued and screwed together for rigidity.
    31975156365_76086977da_b.jpg

    Tomorrow I'll pick up the support stand for building and dressing. I also want to get the feet bolted together and maybe K2 will be taking his first steps.

    Thank you everyone for your encouragement for this project. 16 days until target completion.

    Been back to this thread a few times since I've found it. I may try a suit build once I've figured out cost and just what I'm getting myself into. What was your plan for your upper arms? For a puppet head version, your arms are low of K2's shoulders.
    Were you planning on having your arms visible or making the shoulder joint larger to accommodate?

    It's hard to see in the overlays. But the plan was to have my arms inside his. My elbow becomes his shoulder and my wrist becomes his elbow. His torso would be larger accommodate me inside. Overall he was pushing 9' with the movie one being 7'2"

    So you'd raise the overall torso height to fit your head in. Did you have a plan for altering your shoulder pivot point to accommodate that? If the shoulder pivots from your human elbow, then there will be a lot of extra K2 shoulder sticking out from the body when you move. Here's a picture of what I mean (faint lines are rough original k2 dimensions, dashed lines are proposed changes):
    IMG_20161231_000813.jpg
    (shoulder pivot point arrows should be pointing to the human elbows, not the human shoulders but I realised this after drawing it)
    Or were you planning on keeping the original shoulder height but giving the upper torso line a sharper bend? (red line)

    I was planning on using black fabric to hide my arm and have it in his shoulder below the normal pivot point. That point in his shoulder would be connected to a swivel but my arm would manipulate it. At the end of the day you just have to mess with some proportions to get everything to fit.

    Happy New Year! It is the year of K-2SO.

    Almost all of the supplies I have ordered have arrived. I got my KidzLabs "Robotic" hands. These will serve as the base for K2's hands. I need to beef up the fingers and extend them in foam. I mostly got this because of the price and it provides these great flexible fingers with channels for wires. I've also ordered some clear plastic tubing to run my paracord through to keep it from scratching on a turn.

    [​IMG]

    The 1" pvc pipe will go into the palm of the hand for rigidity.
    [​IMG]

    Overall they are small but I think I can beef them up to K2 size. Which I still have to figure out what that size is.
    [​IMG]

    FOAM! My foam order from TNT Cosplay Supply arrived. I've unrolled the 2'x5' sheets so they can flatten and air out the foam smell.
    [​IMG]

    I ordered a 10mm for beefy parts, making the joint pucks etc. three 8mm sheets for the skin and a 2mm sheet for detail and raised work.
    [​IMG]

    TNT Cosplay Supply will send you thickness swatches for free. This was very helpful in choosing what thickness I wanted to order. Here you can also see my design notebook, chock full of K-2SO drawings, and the Rouge One Visual Dictionary, also helpful.
    [​IMG]

    With no garage I constantly have to set up and tear down my workspace, but you do what you have to do.
    [​IMG]

    This extended vacation weekend I took over my daughters unused room.
    [​IMG]

    On New Years eve I was able to have K2 take his first steps into a larger world. I still need to practice a lot but the fact that the torso is supported by the chest harness and his legs move in the manner I wanted them to is incredible! I took off the neck and arms for this test as the feet were the focus. The pvc frame has a good amount of rigidity but also flexes where I need it to. Once the full skeleton is complete I want to film walking and moving around in a dark room to focus on the white pvc.

    [​IMG]

    I'm still shooting for a 2 week build, and even if I don't hit that deadline it will push the project forward.
    Happy New Year, now go see Rouge One again!

    Assembled the arm pieces. A few screws into the slip ring shoulder to secure the 1-1/4" to 1" reduction. Then my plan for the spider joints paid off. Running a 2" bolt through the joint lets the elbow turn about 45*. So this allows K2 to touch his hands together and bend out about a foot or so. The "wrists" or forearm can also twist 45* allowing the hands to move between upright and palms down. This coupled with the shoulder spider joint which lets the arm reach new angles gives K2 quite a bit of mobility.

    [​IMG]

    Clamped the 1-1/4" coupler in a vise to hacksaw it into two pieces. The thin ring will stop the hip joint from moving. The thicker ring will become the end cap I can remove to remove the whole leg for transport or storage.
    [​IMG]

    Seeing the two rings that will hold the hip slip ring in place.
    [​IMG]

    * the pipe together. I didn't use pipe glue as the reduction left some gaps the glue wouldn't fill.
    [​IMG]

    Added these 4 screws to each arm "shoulder"
    [​IMG]

    Ran the 2" bolt through the spider joint gaps.
    [​IMG]

    OMG OMG OMG, I found the best site, http://www.templatemaker.nl has several adjustable templates you can use to make paper boxes, stars, carriers and CONES! K-2SO has some cones that would be tricky to convert onto the foam but this helped immensely. I could add a margin to the pdf or even have it include measurement guides. This will allow me to transfer these templates to my foam directly.

    This template will be for the shallow but wide cone that makes up the shoulder.

    Shoulder
    [​IMG]
    Next I made the little cone that the neck stalk plugs into.

    Neck
    [​IMG]
    But this is where I got really excited. K2's forearms are 4" wide at the elbow and 3" wide at the wrist, and will be 15" long. This is just a very tall narrow cone! I seriously can't say enough about this cone calculator. It has been SO helpful

    Arm
    [​IMG]

    I've made myself a nested checklist in todoist to keep the remaining tasks on track. Broken into categories like "Head/Neck", "Torso", "Harness/Stand" and so on. I'll keep working daily on this project. Almost all of my supplies are in hand, including the 1/8" aquarium tubing which I will use to guide the tendons of K2's hand to the control glove. But I'll need to get thinner tendon wire as the paracord I got is too thick.

    I'm still pondering a mid January deadline as there I an event I want to take K2 to, but I'm not going to rush him, but he will be done in the next few months none the less.

    Happy making.

    That walk looked great! Looked pretty accurate although the body did look like it should be leaning a bit more forward. That will probably be resolved when you work on the upper body!

    Picked up the K-2SO big fig yesterday. 31" tall.
    He's at 1:2.75 ish scale and functioning as good verification of the dimensions I pulled off of the Black Series figure.
    Also handy for detailed shots of the back and feet.

    Before I forget, here is a link to the public flickr album holding all of my images from these posts and a collection of reference images i've found. Might be useful.
    https://www.flickr.com/photos/8364521@N04/albums/72157666586188843

    Today was about securing the pipe together. Lots of self tapping screws. This images shows the top of the left leg being secured to the 1-1/4" reduction piece and the 1" pipe inside it.

    [​IMG]

    Several screws were placed in the "T" joint at the neck. I also extended the arm pipe by 1" to a total of 7" from "T" coupler to the shoulder spider joint. This is to balance out his arm proportions some as his arms were hanging over his legs and should be more apart than that.
    [​IMG]

    Plugged 4 screws into the coupler and pipe for the hips, this piece cannot fail or his lower half would fall off. For the spider joint I put two screws in the side slots in such a way so it cannot turn. Repeated that for the shoulder joints and will do the same for the knees. Still deciding on the ankles as I may want his feet to be able to twist slightly but we will see.
    [​IMG]

    Here you can see the inner stop secured for the hip slip ring, and many screws in the hip "T" connector.
    [​IMG]

    I also made another Home Depot run, (shocker) for hand parts. Picked up 30 3/4" hinges and a metal carpet edge plate. I plan on cutting it into finger segments, encased in foam. Perhaps I will use my mini bungie cords for the open hand pulling force. The inner pulling force will come from the nylon cord running through 1/4" aquarium tubing down to my puppeteering hands.
    [​IMG]

    I'm guessing a little with the finger lengths but I will mock it up and draw it full size on paper first before making cuts.
    [​IMG]

    I calculated the size and quantity of the joint foam pucks I will need. And found someone who will let me use their bandsaw. The joints will be comprised of 3 slices each. The center puck is always 40mm as that matches the width of the spider joint. This one will be trimmed to different portions of a circle depending on the angle the joint needs to move.

    All of my puck slices are devisable by 10mm increments as the foam I'm using to make them will be layers of 10mm foam.

    The knee is the largest, I won't tell you how long I stared at images of K2 to determine if his elbow joint rings and knee joint rings were the same size or not. ..... (at least an hour). So now I just need to make my square blanks of the right thicknesses and then cut the pucks. Some will have the center cut out for the hollow illusion. Using 2" and 2.5" round mirrors to make them seem like the hole goes deeper (all the way through) than it really does.
    [​IMG]

    You can see in the lower left corner the trimming of the center puck will allow the joint to flex but not move too far. I plan on adding pairs of stoppers to the joints to make sure they don't exceed the angle I want them at. This will keep me from crushing the foam arms against themselves. I found 3/4" rubber ends that normally go under equipment to make them not slide on a table. These will be screwed to the spider joints, one on the flat part of the joint and the other on the end of the turning curve. (I know, an image would explain it better, I'll get one installed and photograph it soon.)
    [​IMG]

    Funds are a little dry at the moment but that won't stop progress as I have almost all of my materials already. My next step is to finalize the leg foam dimensions, make some paper templates, then cut the eva foam mounting disks for the leg pvc and glue it all together. I also need to finalize the foot.

    I can't proceed on the arms until I dial in the hand dimensions and figure out how my puppeteering handles attach exactly.

    Thank you everyone for taking a look at my build. Ask me any questions you like, I do plan on posting final dimensions and a parts list at the end.

    As you can imagine K-2SO is a big star around our household. I didn't know he was such a good dancer. My little girl calls the 31" big fig, baby K-2SO and the one i'm working on the Daddy K-2SO.
    [​IMG]

    My little boy is not quite as tall as the 31" big fig but he's getting there.
    [​IMG]

    I found a new source of K2 images from an ABC story on the making of Rogue One. Watch Here

    But it has great images of the texture, color and weathering of the droid. This picture shows how the base of his neck cone is much wider than I first though.
    [​IMG]

    As well as a one tone cg model.
    [​IMG]

    Which is animated to show some joint movement.
    [​IMG]

    This close up on a elbow joint is very helpful.
    [​IMG]

    There are also clips of Alan using robotic hand extensions while on set. These hand details are great!
    [​IMG]

    It's going to be ok.
    [​IMG]

    So I started work on the feet and ankles, working from the ground up as it were. I had a roll of this transparent cover but the best part was the half inch grid on the back. I can put my foam templates right on it, cut the out and transfer to the foam for cutting.
    [​IMG]

    I also redid some of my dimensions based off of the 31" big fig as it feels more balanced and accurate. K2's foot is 11.5" long.
    [​IMG]

    Cut out the template.
    [​IMG]

    Transferred to some leftover shop floor foam. This has diamond plate on the bottom for some extra wear and tear on the bottom of his feet. This is 1/2" foam.
    [​IMG]

    Marked drill points. Be careful as a drill goes through foam like butter.
    [​IMG]

    Remember that this is just the main base of the foot, the forward toe shell will add a few inches and width to the foot.
    [​IMG]

    I trimmed some of my diving fin to let the future foam layers fit.
    [​IMG]

    I also cut out some of the fin. Only a little bit for now, I want to wait until the whole thing is walking before removing more to be safe.
    [​IMG]

    The ankle joint fits well and is the correct hight off the floor.
    [​IMG]

    I made templates for the layer above and below the ankle joint puck. These will be made out of 2 layers of 8mm foam each. I'll cut a hole in the middle and glue them onto the pipe/spider joint directly.

    I also went over a lot of my dimensions again. I needed to take 4" total out of the legs and add it to the torso. Basically move his hips lower.

    I reworked the puck joint dimensions a little and am happy with there proportion to each-other now.
    I hope to get the feet finished this weekend and perhaps all of my joint pucks in the next few days. Then I'll skin the legs and be ready to work on the torso.

    Keep on building

    I'm really loving this build and can't wait to see how it looks when it's done. Thank you for that link, and all the details that you're putting into this. It's very interesting, and will be a huge help if I ever end up making something like this (it's on my list, but I have other stuff that needs to get done first!).
