    Hello everyone! :)

    May I introduce myself as Mario, a 26-year old hobby artist located in Austria. I’ve been a reader on this amazing forum for almost 4 years but never took the time to actually register or showcase my stuff here; shame on me!
    Over the last eight years I have been quite active in the sector of casemodding but I guess now is the time to try something new ;)
    Except for some of my casemods my biggest success so far was a hand carved, wooden replica of the infamous Majora’s Mask from The Legend of Zelda -series I guess most of you can relate to :)
    The amazing response from fans all over the world really surprised me a lot and made me stick to this amazing form of creativity.
    I opened a Facebook-page with a worklog dedicated to the mask in 2013 but now I decided to have it renamed to a more general name considering I’m going to make this my main page for my stuff, not just Zelda-related things. You’re more than welcome to check out the worklog if you want!

    HALF - LIFE 2 - Gravity Gun - LET IT BEGIN! :)

    Let’s get on with the project I actually want to present you here: the Gravity Gun from the Half-Life series. I’ve been a fan of this series since its beginning and considering I love replicas from various games I didn’t get warm with the Gravity Gun replica NECA made a couple of years ago.
    The lack of the detail is just… argh :X

    So let’s begin. My replica is going to be mostly made from aluminum and acrylics. The parts which are going to end up being metal are the ones which keep the internal structure together and prevent the thing from falling apart. The odd shaped main body on the backside is going to be made from acrylics. I’m not THAT big of a fan of using acrylics when it comes to thing like that but it’s just a nice and comfortable material to work with.
    Designing the gun was one of the hardest things I ever came across but I eventually figured out a way to make everything detachable and maintenance-friendly without losing stability.

    What would a gun be without fancy lighting?
    There will be around 150 LEDs used in this gun, 90 alone for the Xen-crystals. It may sound like overkill right now (which maybe it really is haha) but yeah… love those little lighting buddies :p
    As all of the LEDs are RGB ones and every single of of them eats up 30-40mA there will be a maximum current of 6A(!). Even though I doubt that it will rise that high since not all LEDs are turned on at a specific moment.

    Let’s take a look at some pictures you’re most likely waiting to see if you made it until here :p ;)

    Inner barrels...

    My good friend Michael offered me to have all the round objects (barrels, caps, etc.) which are needed on the backside of the gun CNC-machined from aluminum.
    Considering I was going to create them from MDF and order a bunch of Smooth-On stuff to have them molded and rotocasted… it was a nobrainer to accept his generous offer.
    So he spent a lot of his spare time just to hand me over those two babies… THANK YOU MAN! :)

    [​IMG]

    [​IMG]


    ...and outer barrels!

    Those two bad boys will not just reside useless at the back of the gun. They are chosen to hold all the electronics which are needed in order to control all the lighting for the Gravity Gun. Each one of them will contain a custom-designed PCB-shield for the two Arduinos which are going to end up there.
    Why two you might ask!
    Well, the program which runs the effects for the xen-crystals just barely fits on the internal memory of one of the Arduinos so there is no more space left on one device to handle more.

    [​IMG]

    [​IMG]


    The structure...

    And this is how the thing should be held together on the back. An aluminum pipe is the core element where all other machined parts are mounted on.
    This pipe is getting cut at an angle and some 1cm thick PVC-inserts (which are left to be machined) are going to get screwed inside the outer ends of the pipe. This will give me a proper surface to mount the outer barrels :)

    [​IMG]

    The bigger pipe represents the main barrel of the gun. It kinda feels a little to big to be honest but if I did my math correct and didn't screw up constructing in in AutoCad completely... I should be fine haha.

    [​IMG]


    Here are the PVC parts I need to machine first...

    [​IMG]



    Unfortunately this is all I have for now but there will be a huge update this week as I’m now waiting for all the laser cut parts to be finished.
    Fingers crossed I can pick them up before the weekend! Hope you like it so far although it's not much of a first update... :)

    Stay tuned for more! :)

    This is awesome. I'm subscribing. This should hold some great inspiration for the ASHPD I'm currently building. What are you planning for a power supply?

    Thanks a lot man! :)
    I hope there will be so you can give me some hints on that since I'm planning to give it a shot in the future too :)
    As a power supply I'm planning to get a 6A one for the 230V socket. Having it unplugged it should switch to an internal array of NiHm-akku cells which should deliver the current it needs. Need to figure out where to put them though...

    Re: Half Life 2 - Gravity Gun Replica (CNC stuff!)

    My progress is very slow. With a house and a family and full time job I don't get to work on it as much as I would like. I haven't posted here because I don't have a lot to show...yet. I've spent the past year and a half just on the barrel since I want it to be just right. Like you I'm trying to make it maintainable if possible. Always easier said than done. I also slow myself down as I didn't have a solid plan at first and kept changing things. There was about a month or so just sorting the electronics for the thing. Everytime I do something I go back and test everything together just to be safe. This has saved my bacon more than once. The electronics are sorted design wise but I used perforated PCBs and don't like them. im now in the middle of etching custom boards for everything. I've learned a ton though.

    Your's is fancier than mine, sounds like it will have to use this setup for it to work at all.

    I totally feel you! I could have been the one who wrote your text now ;)
    I'm designing the gun for around 4 months now (with shorter interruptions) but if I look back at the first draft I did and compare it to the model I have now... man I am glad I took my time. I sorted out SO many errors and flaws. Since laser cutting is quite expensive though it's kinda pressurizing to have everything exact! :)
    But I take my time and like you I did learn a lot throughout the building/construction-progress :)

    Can't wait to see yours!

    I'm going to follow this one!!!
    This looks like its going to be a super detailed build. And as a huge fan of HL i can't wait to see more!!! Been looking around for a prop to carry with my HEV costume and i was doubting for a second to buy the NECA one, but after reading that the detail lacks allot i might just make my own one day. I will just carry a crowbar with my suit for the moment.

    Hoping to see more soon, it looks really promising!

    Really, you did a HEV? Wanna share some pictures?

    There will be a huge update this weekend as I got all my laser cut parts today... stay tuned!!

    Half Life 2 - Gravity Gun Replica: LAZOR STUFF!

    Hey everyone! :)

    UPDATE TIME!
    I managed to pick everything up from the laser guy and already began to throw everything together.
    Feels like I was buying this thing from IKEA looking at all those parts... and this is only for the main body.
    It would have been nearly impossible to cut this all by hand considering all this stuff needs to be totally exact when it comes to dimensions. Glad I went with the laser ;)

    [​IMG]



    This is what the main junction which holds everything in place should be looking like in the end.
    The two M12-rods will be connecting the main barrel to the rear of the gun and act as additional support beams running through the whole structure.

    [​IMG]



    Tow little temporary mockups :) The barrel is too long though!

    [​IMG]

    [​IMG]


    On with the progress... after searching all the parts which are needed first I carefully aligned them and started glueing them together! :)

    [​IMG]



    While I was waiting for the glue to cure I started working on the end cap for the main barrel.
    The little slots are supposed to be holes to let the cables of all the LEDs come from the barrel to the inside of the gun and connect up with the power sources and Arduinos.
    Also you can see the two holes for the M12-bolts.

    [​IMG]

    [​IMG]


    Et voila! :D The glue cured and I was able to put everything toegether.
    The glue which is spreading out shouldn't bother you too much... will be removed in the process :p
    Unfortunately the big pipe for the barrel isn't perfectly circular so I had to widen the whole in the front a little bit to have a nice fit.

    [​IMG]

    [​IMG]

    [​IMG]

    [​IMG]

    The next thing is to create the whole casing for the main body. But this will be done in the next update! :D
    Hope you're liking it so far guys!

    Take care,
    Mario

    I've send you a pm with a link to pics of the suit.

    Those lasercut parts look absolutly perfect. Can't wait to see more. This will probably be one of the best looking Gravity guns out there if not 'the' best.
    And your pics look like freaking studio photo's. I guess photography is one of your hobbies aswell :p.

    Thanks a lot man! I'm glad I found a store which has great prices when it comes to laser-cutting stuff like that.
    Searched for an eternity but it totally paid off!

    THANK YOU!

    Oh, I didn't check my messages! Sorry mate, will get back to you asap!
    Thanks a lot for the nice words regarding my photos. Yeah I tried to get into people photography a few years ago but the motivation went away. The stuff and "experience" stayed and is now used for documentation purposes :)

    Watch out for this becoming stupidly front-heavy when holding it. Aluminum is a really cool route to go, but unless this is just a shelf display piece, you probably won't be able to hold on to it the way you're "supposed to" with the 2 handles in the back. I don't know how the Neca ones compare to the Gravity Guns that Volpin and I have made in terms of weight, but I know I can't hold mine straight out for very long.

    Are you building a specific version? The game model and the world model differ greatly. The Neca gun also takes some interesting liberties with the design (although to be fair, it was designed by Valve).

    EDIT
    And for what it's worth, the aluminum structure may be overkill. Mine is 100% acrylic and cast resin, and the front half with the barrel bolts onto a 6mm acrylic plate on the back half, and I've never worried about anything breaking. I definitely don't baby mine either, she's a display piece at every event I go to and plenty of people manhandle it.

    Re: Half Life 2 - Gravity Gun Replica - UPDATE: Lazor time!

    Hey there!
    I was looking at your worklog here before I started working on mine! :)
    It will mostly be displayed on a stand although I did the math and IF I didn't do it wrong my Gravity Gun should have a perfect balance between the front and the back. Since most of the frontal area consists of just an aluminum tube and some small layers of acrylic the weight will occur mostly on the back where its held. I don't know how much the crystals are going to weigh but that shouldn't influence the whole structure a lot to be honest. I'm quite confident that the whole thing is going to have a perfect balance when it comes to holding it.
    It's mostly based on the one of NECA/Valve, but there will be some considerable changes done to tweak this beauty a little bit :)

    To your statement regarding the aluminum and overall resistance. I chose aluminum over resin because I really like the feeling of having something sturdy in my builds. I would have chosen aluminum over the acrylics aswell but it's just no fun glueing to be honest ;) Also for making the lathed parts from resin I would have needed the lathe anyway to create the master for the molds. And considering the price for Smooth-On Mold Max and the resin... it was a no-brainer for me to choose what I had available :)


    Anyway, here's an little update for you guys!
    All the electronics arrived from Adafruit and I cannot wait to get them going! I only had time to align the circular RGB-LED ring in the middle of the tube and drill holes for the cables for powering and controlling it. I will get into details more in the next update!

    [​IMG]

    [​IMG]

    Since the workshop has been in use today there was no space left for me. So I banned myself infront of Photoshop and created the face of the gauge which will be placed on the left outer cylinder in the back of the gun! :) I think it came out pretty well, altough it isn't finished yet.
    This is going to get printed translucent and applied to a special kind of light-reactive acrylic which is going to get lit by some LEDs in the back.
    Those LEDs are going to get controlled by an Arduino aswell and will make the whole gauge flicker here and then to achieve the look of a shortage.

    [​IMG]


    Hope you like it, even it's just a shorter one!

    Re: Half Life 2 - Gravity Gun Replica - UPDATE: Lazor time!

    If at all possible, vacuumform them out of clear plastic such as PETG. Mine are cast solid from Smooth Cast Crystal Clear, and I want to say they are around 2-3 pounds just by themselves. That doesn't sound like a lot, but when you are hanging that weight 18" out in front of your arm, it adds up really quick.

    If you don't have access to a vacuumformer, send me a PM and maybe we can work something out.

    Everything else looks great!

    Thank you so much for your kind offer!
    But there are a few restrictions which prevent me from vacuum forming them. The crystals aren't going to look to look that smooth as they are now in everyone's replica.
    I want to achieve an effect which makes them look like real, cut crystals :)

    TOTALLY!
    Unfortunately it seems my RGB-strips are broken as I tried to get them running for around three hours :(

    Re: Half Life 2 - Gravity Gun Replica - 07.06. - Body finished... kinda!

    Thanks a lot man! Great to hear you enjoy it :)

    Many thanks for offering your help, I finally got the LEDs working. It seems I burned the first LED in the strip since I didn’t use a capacitor from the beginning. The current must have killed it. Now it’s working like a charm!

    So let’s begin with the update.

    Sorry for the bad quality of the images, I didn’t feel like photographing and pre-production so yeah… did it anyway haha. The white acrylic parts are even harder to photograph but I didn’t have a flash on hand.

    What I had actually was enough time on the weekend to get the body of the gun nearly ready :)
    The first step was to grind all the acrylic plates which are used for the shell to the right angle and form the outer shape. This was a fairly quick process and so one after another got glued onto the base plate. I let every sheet dry for about 30min.

    [​IMG]

    [​IMG]


    While waiting for the glue to dry I used the time and went onto creating the back plate. It consists of two pieces which quickly got glued together aswell.

    [​IMG]


    I totally forgot to create holes for the M12-rods to come through and so I quickly cut it out of the back.

    [​IMG]

    After all the glue dried I finally could mount the backplate on the main base.
    Here are now a few shots :)

    [​IMG]

    [​IMG]

    [​IMG]

    Now the tricky part begins… I need to make some calculations for the rest of the pieces which should cover up the upper back of the gun.
    Those are the plates where both the Xen-barrels are going trough.
    Since the Xen-barrels got quite an complicated shape it’s much harder to get the correct measurements on cut-out than I thought it would be :(

    Anyway… fingers crosses! Gonna drop the files to the laser guy tomorrow to hopefully pick it up on Wednesday! :) I’ll keep you updated!!

    Cheers and take care,
    Mario

    Yep.. need a cap & resistor, as stated here:
    https://learn.adafruit.com/adafruit-neopixel-uberguide/best-practices

    I too love the electronics part of builds.... if fact I'm to the point that if a prop doesnt have electronics.. I'm turned off (as it could be so much more if the developer/designer wanted)

    Great job so far!

    Yeah I found that page now too, thanks a lot. After adding it all went fine. Additional to that I had a major error in my program.
    Guess that both of that resulted in not working haha. *facepalm*

    I'm with you there on the electronics. It breathes so much more life into rather "cold" stuff.
    I was thinking about adding a speaker for sound effects too but I for myself think that this would be too "toyish".

    :)

    You sure did, really appreciated your offer!
    Cool you like my little shop. It's rather small but I've got everything I need stuffed somewhere in it.
    A laser is missing ;) :)

    Also.. I' dont know about toyish..

    getting the 'go-to' BlasterCore 4.0 electronics always sound pretty good on all the videos I have seen..


    I did these with adding Arduino based sound FX:

    you can use whatever .wav file you want for sound.. so use whatever you think sounds best.

    :O You don't have you? I envy you so much man...

    Holy...
    Woah first of all the paint job on the Maverick is just phenomenal! Great job there, hope I can pull something like this off too.
    Did you use acrylics?

    Also the sounds are incredible as are the lighting effects. Did you use an Arduino to control the BlasterCore?
    I dunno but I guess if I would go the way to include sounds on the Gravity Gun it would kinda "ruin" it.
    Maybe it would have to grow on me ;)

    Thanks! Will do sir! :)

    haha.. thanks.. the Nerf Maverick was the first paint job I have every done.

    just a base coat/color...
    some dry brushing weathering technique on the edges and high spots.
    then some black 'wash' in other areas.



    Not sure what you meant by this: "You don't have you?" ??? :)

    Also.. no, this is NOT using a blaster core of any kind. I was saying its a popular choice and a 'turn key' product, and also a quality product from what I know.

    my links use an Arduino based solution (think Arduino + Adafruit Wave Shield built into one tiny board)
    for myself.. that gave me the ability to tweak it for my uses (ie: bar graph, 7-segment counters...etc)

    but the BlasterCore gives you some options as well.. I am not too up-to-date on it.. as I have never owned one personally.

    I was just showing the links to display it doesnt have to be 'toyish'.. and adding electronics (to me) brings the prop to life more. :)

    Ah dry brushing was a thing I've never tried actually. If I ever need tips regarding painting the gun I'll get back to you! ;)

    I meant that you have a laser! :D I don't know a single person having a laser in their workshop.

    Oh I see!
    Adafruit makes THE stuff if you ask me. Especially for prop making they simply cover nearly every aspect when it comes to fancy lighting.
    Can't wait what they might come up with in upcoming years.

    I'm kinda twisted about sound effects since nearly everytime I hear sounds coming from a prop (be it a weapon or robot, etc.) I automatically think of some 90's kids commercial where all those toys with the "fancy" electronics and sound effects launched haha. Dunno why. It depends on how it's used on the prop though.

    I somehow cannot imagine the Gravity Gun making those weird noises :D

    I think the main problem is the manufacturers use crappy sound modules. Case in point is the NECA ASHPD, which, when compared to the rest of the thing, has pretty crummy sounds that I just want to turn off (but I don't want to open mine up to add a switch). Same with the ForceFX sabers as well. If you could find/use a decent digital sound module, I think it would be fairly trivial to grab the sound files from the Source SDK and add them in (although I cannot for the life of me remember what the Gravity Gun actually sounds like...)

    I'm a fan of sounds and think it rounds out the package nicely. I agree with @Fishbowl if not done properly it sounds bad. Most of the off the shelf units use subpar components and achieve subpar results. I am adding it my ASHPD I hope it sounds as good as I think it will.

    Yeah.. thats always the problem (well usually) when you got a mass produced piece.. cost is a huge factor. (so they may skimp..etc).

    But if you buy a purpose build electronics kit (BlasterCore for example), you quickly see the difference. Its a top notch, quality product that BUILT for props and audio in mind. :)

    Size is also another concern/factor..


    I mentioned the Adafruit Wave Shield.. (and Adafruit makes great stuff.... their support forums can be a bit 'meh', unless its there product..but whatever) lol..
    because thats 'sorta' what my board is based off.. and uses their libraries..

    however.. I custom designed my board to be SMALL and more a generic platform:

    you can see my custom board vs the Arduino with Wave Shield stacked on top (see the size difference)

    http://dmstudios.net/misc/scab_assembly/all-in-one_2.jpg

    http://dmstudios.net/misc/scab_assembly/all-in-one_1.jpg

    I use my same board as a base for most of my projects

    Nerf mod
    DC-17
    Iron Man motorized faceplate w/Sound FX (servo and eye leds too)..etc

    so for me.. its my 'go to' board...



    re: dry brush...


    first tie I ever did it.. search around, especially YouTube.. you'll find lots of tuts..

    for myself.. I found that using DRY brush with a VERY VERY VERY tiny bit of paint on it works best..

    you'll be amazed at how much paint you DONT NEED!..lol..


    yeah people get sound files from video games, DVD's...etc.. or just legit audio engineer new sounds.

    www.saberfont.com has mostly light saber sound FX.. but it has a few blaster packages as well..

    i went with a sound board from Bob replicaprops. I love the simplicity and the fact he had the audio files from Volpin I believe, it was easy. I used a perforated board originally and hated it. I've since done a custom etch. It's not the best looking piece but it's much more solid than the perf board.

    Guys you're starting to make me feel weak about adding sounds aswell.
    I'm just figuring out where the board should go (which shouldnt be a problem) but the main concern I have is where to locate a proper speaker.
    I mean there is plenty of room inside the main body but I cannot just simply pack it somewhere outside to be seen.

    What kind of speaker do you think is proper for a decent audio quality when working with the Adafruit shield?

    Had a quick look around and it seems this one here should do the job pretty well: https://www.adafruit.com/products/2217
    Have no experience in audio shields like this though.

    Awesome, even found a shop here in the EU.
    Do you have any video of it perform? Like in good quality? Curious how it sounds... :)

    Only video I have of it in use (I think) are the DC-17 and the Nerf Maverick mod ones...

    but again.. it will depend on the board itself that drives the speaker.

    (I found that the Adafruit Waveshield by itself, (not my custom version one) volume is kinda low... (but there is a fix/hack to get it louder if I remember correctly)

    I have video of my setup I posted in my thread if you want to see. It uses a class D amp which is a little bigger than a penny. I then use an 8 ohm .5 watt speaker with it.

    Ah awesome to know! I think I will read me into that stuff a little bit more.

    Of course I want! :) I'll check it out!

    Re: HALF LIFE 2 - Gravity Gun Replica - 07.06. - Body finished... kinda!

    Thanks a lot man! Welcome onboard! :)

    And on with the update!
    It's not a huge one, but I got a lot of stuff done. It's the details that takes your time the most. I'm always underestimating how long this all takes.

    The cages/casings for the Xen-crystals are two layered pieces of acrylic in different strengths. I sanded the inner edges where the parts come together to create a seam around the inner area which will get special treatment (worn, rusty, etc.) later on.
    I had six 2,5mm holes lasered in every single on of them where tiny acrylic rods gets pushed into to keep the pieces aligned perfectly when stacking them.

    [​IMG]


    Here are all six of them nearly finished. The element which connects to the main ring on the front is left to be glued on.

    [​IMG]


    While all of the cages were drying I started creating the heat exchanger which is located at the bottom on the back - IKEA style!

    [​IMG]


    First of all the edges for the outer casing had to be cut at an angle to make them fit together nicely.
    While the glue was drying again I had time to start sanding the heat-spreaders. The cut-outs of the part below are 2,2mm wide and the heat-spreaders are 2mm.
    But because I use casted (and not extruded) acrylic for this build the thickness of the material isn't quite what you expect it so be.
    All of the 16 spreaders had different thicknesses from 1,9 - 2,7mm...

    [​IMG]


    I also started a little bit of dremel work and did a few indents on the spreaders to make them more realistic.
    More will be done later on of course.

    [​IMG]

    [​IMG]


    Aaaand temporary layed out on the back :)

    [​IMG]


    My friend Michael came over too and brought me the first of the (now) finished Xen-barrels for the back. I asked him to drill some holes for the mounting system in them. THANK YOU SO MUCH BUDDY! They are gorgeous! :)
    Those two will hold the whole structure together. One is already finished, the other one will be finished on Monday :)

    [​IMG]


    And a quick mockup! :) The outer barrels aren't aligned correctly btw.

    Hope you like it so far guys! I'll keep you updated! :)

    OMG i'm baffled. It looks amazing SupermaRiio. Seems like everything is measured to the mm. Amazing work. What is your plan for paint? Airbrush or regular brush?
    And again, thoso photo's..... this is a whole new lvl of making threads. -.- .

    Btw i finished my suit (quick suit up pics, better ones are coming) :

    It really is haha!

    HOLY MOLY you even LOOK like Gordon haha. SO awesome dude! This suit rocks!
    Guess we should do a meet-up when I'm done to make your outfit complete ;) :D
    Love your little buddy on your shoulder.

    Got one too! :D Made this image back in 2009!

    [​IMG]


    Thanks a lot for the nice words regarding my photos! To be honest it's just a little point'n'click with a extremly expensive lens haha.
    Regarding the painting I'm not quite sure though.
    I guess the main paintjob will be done with spray cans whereas details and weathering will be added with acrylics.
    Not a big fan of airbrush even though I own one. Tried a little bit on my wooden Majora's Mask but in the end I felt a lot more comfortable just using acrylics and all kinds of brushes (and my fingers haha).

    This acrylic work is spectacular, there is something to be said for over-engineered prop-making!

    HALF - LIFE 2 - Gravity Gun Replica - 16.06. - HUGE UPDATE! Ton 'o pics!

    Really appreciate your kind words man! Always nice to hear feedback on your work :)


    Electronics!

    And let's go on with the update! This time quite a huge one even though it won't look like it haha.

    First of all I needed to mill a little blind hole for where the electronics of the upper part are going to reside.
    The little holes are for leading the cables inside the main body.

    [​IMG]


    Here is the first one of the RGB-LED modules which are going to be used all over this built.
    Each one will have a different fading/pulsing pattern running on them.

    [​IMG]

    [​IMG]

    [​IMG]


    Aaaaaand here's the bigger module for the main barrel.
    I used some temporary mounting methods to show you what it's going to end up looking like.

    [​IMG]


    Assembled...

    [​IMG]


    ...and hooked to the main chassis.

    [​IMG]

    [​IMG]


    Sooo... all of the RGB-LEDs need to get their data-input from somewhere, righjt? Right!
    I created a special shield for both of the Arduino micros which are going to get hooked up to all of the electronics later on.
    Each of the shields supports 8 PWM outputs for LEDs and 2 analog ones for buttons and other manual input devices.
    They will be placed in the outer barrels... soldering is left to be done yet! ;)

    [​IMG]


    Heavy metal!

    I was facing another problem with the main barrel.
    Since all the xen-crystals should get illuminated by LEDs aswell I had to mill some indents along the main barrel to have the stips flush with the outer diameter. Now I do not have to bug around with milling slots along the crystals since if they are going to end up in clear orange resin you will see every cut line in them.

    My awesome friend Michael helped me out on this one too and again spent his spare time to get this thing going...
    Asked him on Sunday afternoon, got it on Monday... this guy is simply crazy!
    Without his insane help on all the lathing stuff I would not be able to create this project in the quality I had hoped it to end up in.
    THANK YOU SO MUCH! I owe you one buddy! :)

    [​IMG]

    [​IMG]


    He also finished the threading of the second one of the inner xen-barrels. Again Michael... awesome stuff! :)

    [​IMG]


    Now what's left to do is to cut an straight angle on both to fit them snuggly and flat to the back of the chassis :)
    You can see the two M12 rods running inside the main body.

    [​IMG]


    Hope you guys like it so far! Prepare for the next update as it will be quite a huge one! ;)
    I will try to get the main body going and start priming it.

    Cheeeers,
    Mario
