    My kit from Ebay came in....This guy is HUGE! Much bigger than I thought the prop looked on TV!

    Any tips and tricks from Servo builders? Maybe I'll put a LED in his head and make him a lamp ;o)

    We start building this on monday, when my rusty metal red, or whatever it is called, arrives...and I pick up some more primer.


    First stop, is to drill all the holes needed and do a rough assemble....then we'll dis-assemble and prime, then paint.

    After that all comes together, we'll see how well it all goes back together..about the only good thing about working in an electrical contracting office is that you already have all the tools needed to put these things together...

    Well, not as much progress as I would have liked today :)


    I ran into the first problem, I can't get his dome off without a hair drier to loosen the plastic up around the edges.... the second problem, is that the krylon prime doesn't really stick to the molded parts, even after a good sanding.....Where can I get tom servo approved paint and colors?

    I had no idea there were Tom Servo kits available, cool!

    Are you using a plastic primer, like Krylon Fusion? If that doesn't work try Duplicolor self etching primer.

    And if I recall correctly they are fairly priced at $149 or so. Keep meaning to pick one up one day.

    Here's my bots:

    I got the same kits from MST3KGuy (Bob)...he's really awesome. I wanted to build my own Crow instead of buying one and Bob was very helpful with supplying separate parts.

    The head is one of the more difficult parts of building Tom. To get that dome off, you need a hacksaw or a dremel. I'm working on a tutorial on how to make Tom Servo and here's the first part:

    http://www.youtube.com/watch?v=qDUk-Px-C98

    Are you planning on rigging the head so he can talk?

    After you primer the head, go with a cheap red for the base coat. I used Rustolem (I think the color was called Colonial Red or something...I'll let you know later), but the really important accurate paint is Testor's Ruby Red Metallic. They come in 5 oz cans and are a pain in the butt to work with. When you paint the Testor's Ruby Red, go with VERY light coats...you put it on too thick, you can very easily mess up the paintjob. After a good day or two of drying, clear coat the parts.

    EDIT: Also, I recommend you use hot glue or maybe an two-part epoxy for attaching the bottom lid to the head and for attaching the top lid to the dome. Superglue doesn't really hold well and it will fog up the dome.

    I had Krylon, and for whatever reason, that didn't stick :).

    I got a different primer, and this one actually does stick, so all the parts that need to be done are primed. If I can figure out the instructions, we'll try and get some drilling done today :)..

    Good luck!

    For the barrel, drill the top for the PVC pipe to slide through. One of the more difficult parts of the Servo build is attaching the bowl to the barrel...I held the bowl and barrel upside down and drilled into the flange or lip on the bottom of the barrel casting for bolts. Then I drilled a hole into the bowl for the PVC pipe and fed bolts into the holes to hold the barrel flange to the bowl. I also used nuts and bolts to hold the Turbo trains onto the bowl. The arms are weird because of the way the bolts are placed on the arm piece. Basically, drill holes through the vacuum formed shoulder housing and mark where the bolts touch the barrel. Drill, rinse, repeat, haha.

    hey all, thanks for the tips :)..

    Does the 'pipe neck' for tom servo have to go in straight? Mine only really sits at an angle and I'm afraid to glue it in like that.

    [​IMG]

    Some small progress yesterday. Parts got as lightly primed as I can do. Hopefully I'll stop procrastinating and get some holes drilled today. I really want to do this one right.

    And yes, to the question asked before, we are going to wire his mouth up for talking :)...

    we got a little further today. I got the hole drilled for the front of the barrel done....His engine block can be put on now.

    For next week: We'll try and finish up the head and remove the fishbowl so the head can be painted. then we'll see about centering the swivel part of the top barel.

    There's a little dip in the resin on the top of the barrel. This is dead center of the barrel and where you wanna start drilling. I grabbed a circle template, drew a 1/2" circle around the center dip and began drilling. The hole doesn't have to be perfectly round, but it's important that the pipe shouldn't be fitted loosely through the hole. Drill the hole so that it's big enough for the pipe to pass through and small enough so that it binds...if the hole's too big, his head will be tilting everywhere.

    I'm curious about your engine cast, do the engine stacks have holes all the way down or are they just little divots? It's nothing important, just wanna know. :)

    To rig his head, I recommend that after you tie a knot to the fishing line that connects to Tom's lower jaw, go ahead and hot glue that thing. Hot glue holds a lot better than
    superglue...I found out the hard way when I was showing him off at a convention, lol.

    stupid question time.. you don't have to cut that superlong pipe any, do you? I assume it gets attached to the neck, and then that runs all the way to the bottom and that's how Servo's head is controlled?

    Today's agenda, get the hands attached and screwed on to the barrel. Tomorrow we'll worry about the metal swivel piece, and pipe hole. Taking this one step at a time :).

    Mr.Sinister... Just little divots :). are they supposed to go all the way down? :)

    We made a bit more progress today. As recomended, I hot glued the hands to the white shoulder plates. The holes are drilled and he's temporarily fitted. Same goes for the engine block. I'm not sure how I'm going to paint the engine stack part white just yet. I also got his metal head swivel-er in place..hopefully centered..

    Once everything looks good, I'll begin final assembly.

    Tommorow, we will use the hole puncher to drill a hole through the bottom of the bowl and barrel and hopefully get the rest of the holes done.

    Well, as you can see, we've h ad some set backs... :)..

    somehow, I'm still not sure, we've gotten some red paint on the bowl. I'll now have to see if I can lightly chip it off, or get some whiteout or real white paint to cover it up.

    Second issue, I thought maybe I could lightly spray tom's head without hitting the bowl, since I'm real nervous about trying to pry that thing off without breaking it, even using t he hair dryer method........ even covering it up, didn't work so well, so now we've got to chip that off :)..

    other than those two minor problems....it's not coming along that bad...

    The head swivel part is attached. His shoulder pipe thing is glued on to the huge pipe. his barel is now attached to the bowl. His arms can fit in to the barrel. I've just got to find a way to attach his hands without breaking the slinky, drill the hole for the pipe, attach the string to his mouth, secure the pipe, and get a finished paint job that looks good, and I should be done....

    If I where to build a second tom servo, I'm sure it'd go easier... first one always has issues ;o)..

    well, we got nothing done today..

    But I did bring tom's head home, so going to try the blow drier trick now and see if it works.

    I'm also a little confused on how the string attaches to the jaw. The Jaw Pulls up to open, but if you use the string, it'd have to pull down to work..does that make sense? Curious if anyone has any pictures of there's for better under standing :)

    Almost done with Mr.Servo.

    I got the hole punched Through the center and the bowl. It fits in pretty snuggly. I'm re-painting the dome so it looks a little smoother. I'll get the paint for the engine stacks and his mouth to finish that up. I hope to get the bowl removed this afternoon so I can get his face painted up.

    Tommorow, I'll get the string attached to the mouth, I'll hot glue in the 'Shoulder' to the head, and secure everything else off, and the only thing left to do, is somehow attach those train things around his bowl. Not quite sure on how to do those yet, if you have to cut away the excess plastic, there will be nothing left to glue on to the bowl...

    I loved making mine. It cool to see people still building bots from the show. I did have an issue with someone breaking the mouth control string so when I fixed it I used 550 paracord.

    I cut the pipe down to 9 inches, and then connect a 1/2 PVC connector to the bottom of that. Slide that pipe through the bottom of the bowl and slide it into the hole at the top of the barrel. The connector helps act as a bumper for the bowl. Then connect a 3 and a 3/4" inch PVC pipe to that and you have Servo's control rod!

    To paint Servo's head, go ahead and attach the head to a spare PVC pipe and paint it disassembled. Here's a video on how to paint your bots:

    You need to install a small picture hanger inside Servo's head to act as a pulley for the mouth to work. Drill a hole through Servo's head, thread the picture hanger through there and thread the string from the PVC through the picture hanger and attach it to the jaw flange. Here's a video on how to do it:

    And thanks for that video :). The only good reason for working in an electrical contracting warehouse is we have every kind of tool imaginable here, and that saw was in the back ready to go, so off came Servo's head :)..

    and thanks for the video. I've now got the head primed and it's waiting to dry. We've also got the other parts re-wetted with water, sanded down, and primed. Once we get the remaining drill bits done for Servo's mouth, we'll paint them sliver and the engine stacks silver and then finish off with the red.

    After that, I'll glue in the T-connector once the string is attached and try and assemble the rest of the body before the day is through.

    Today's progress... I got the rest of the engine block painted without wrecking the silver portions. I got the hole drilled in servo's bottom mouth. His barel seems to have come out decent enough for my skill level of spray paint, so I drilled a hole for the front to place my newly bought Tap bit in, so I can twist on his engine housing. I also got the rest of his head bowl evened out and sanded down.

    On Monday, hopefully the paint on his head will have dried OK for a final. We'll drill the hook hole and begin final head assembly. we'll paint the little line center red on his engine block and place that on the body. His hands will finally be secured. And we'll get the remaining bits done on the bowl..

    Do you have to cut away the excess plastic on the trains, or do those stay on and that is how they glue on to the bowl?

    Today's progress... The only thing left to do assembly wise, is find a way to glue the train sets on. His barrel painting came out good. The wire drilling came out good... his 'shoulders' are screwed in so his arms can stay on...

    The only snafu is the head. I think when I took the mouth off, I broke off the part of the bottom jaw that the spring connects too...if there is another way to get the spring to stay, I'll hot glue it on and hope that works.. otherwise, I may have to order another head from amazon.

    final pics will come this week, and see what everyone thinks of my attempt :)

    Today's progress...

    replacement head came a day late. We got the dome properly sawed off. This time, the spring was removed first before popping the mouth off (doh!) and the holes drilled before painting. The head has a final paint. waiting for the dome top and mouth to dry.

    This time tommorow, Mr.Servo should be done :)....then it's on to decide if I want to try Crow, who looks far more complicated :)

    Mr.Servo's bottom head, done the right way this time.. fully rigged for puppeteering. After lunch, i'll cut the last of the puppet rod that goes up his body. I'll sand off the top of his head so it's flat, glue on the part he bowl connects too, and finish it up...

    Quick test fitting of the head. I THOUGHT the belt sander was in so I could smooth off his red dome, but no luck. have to wait for one of the trucks to come in and hope they have it. Right now, I'm trying to hot glue the trains on...if I have to, I'll also hot glue in hands to the springs and hope it doesn't show up so at least I can finish that up today..

    Add on : And it's not Testors ;o)....The one testors that I DID have really was true to size in the picture, and no bigger than a shot glass :). I got what I THOUGHT was a dark red from home Depot, but it clearly turned out far lighter than the cap indicated :)

    We got his trains on..but there is going to be some glue trimming that is needed...At least they SEEM to be staying on.... I don't think gluing the hands on the springs is going to work.

    hopefully final picture tommorow

    I finished mine last night. The testors ruby flake paint was an absolute nightmare. 2 out of the three cans at the hobby store didnt work at all. They started by spraying red sillystring looking paint out. Then when they got passed the glob, it sprayed out runny and globby. It messed up the paint on the head, and I didnt get as thorough a job as I wanted in the back of the barrel, but it'll do for now. I plan to call Testors tomorrow to complain and hopefully get replacement cans.

    Neil, you really don't need to glue the hands to the springs. I simply just grabbed the spring and carefully slid the hands in...works great and a hand only came off once during a con.

    Great job, jtmtmtl! Yeah, those Testor's spray paints are a big pain in the *. Fortunately, Tom Servo is easier to paint then Crow. I need to figure out a good way to make the paint stick to Crow's * Tuppercraft trays.

    I got one of his hands on that way once, but it was only one ring, and then I noticed it was the wrong hand after ten minutes of trying ;o).. I finally got his head and dome glued on, so that's done.. only thing left is the hands :).

    For the most part, finished! I've still got to paint his center engine block red...and for some reason, two of his train tops arn't sticking to the bowl, but other than that, he is all assembled and fully puppetable.... :) Far bigger in person than he looks on TV ;o)
