Done the little finger tips, quite had as the "pad" as I said is wider than the finger part
then drill everything 2mm or 1.7mm if its going to be taped to M2 thread. Each joint has a screw both sides except the ones with the hydraulic pipe fitting, so all screws had to be cut down accordingly.
then there was a big spark! and he's got me aaaaaaaaaghghhhhhhhh
..... it gets worse, he dives for the knife!
PUT THE KNIFE DOWN! it'll be ok. I manage to persude him to give up and let me trial fit to the shoulder.
Ok back to work, no where near finished yet im afraid, each finger section thats each one, needs a little protective cap. These are so small and fiddly I will have to use styrene, made a start on one.
more on Thursday.

Ok getting better with styrene now
easy to work the stuff as its so soft, but quite easy to make a mistake too
giving it all a blast with grey paint
not easy to file these like this by hand
now this looks good!
very proud of myself here

Thanks guys
Yes all joints work, the arm can be moved to any position as will all the other arms. Might be nice to recreate some poses from the film.
Mini gun arm is arm 2 in my opinion

Finishing the arm off now, elbow covers
installed with the pipes under it
other cover was a bit more complicated
Now onto the big shoulder cover. Very hard to get the size right for this, had to look at a lot of pictures. It stands away from the shoulder so its hard to measure in the pics.
After about 40 minutes of drawing pictures and measuring I start with a block of delrin
work out the angles
I rough cut the curve out then used a rough sandpaper on a tube to file the curve smooth
hollowed the inside out and test fit
the little box that sticks out, again hard to imagine the shape to cut out as it sits on the curve
looking pretty good
got these tiny hex head screws through, perfect for this sort of thing, I had to drill a 1mm hole in the top so the wire can sit in it
this was very fiddly, felt like making a house of cards
all attached and sprayed grey so its easier to see the shape.

yet more work on the fingers. These little rivets have a 1mm head and a 0.5mm stalk. I bought a tiny variable speed drill for the job, using a 0.5mm drill bit.
and then painted over, done this on all the finger guards
something I had forgotten to do. Another lump of delrin.
fits in that quarter
had to file it by hand, not easy. Took me a while to work out what this reminded me off, then I got it! the apollo capsule! just imagine it with a parachute out the top splashing down in the Atlantic.
put the hardware on the other side, some meaty 5mm hydraulic fittings
added the tiny hex heads to the nuke bin
...and made a start ont he fittings on the other shoulder disc

Amazing! subscribed and now wanting to buy a lathe
thanks , the lathe is handy but the mill is essential. I made all 4 of my guns without the lathe.

what are u using to shape the plastic on pieces ?
epic work
the black delrin I machine on the mill, but all the shaping curves, detail etc I do by hand with a file.
I'm also looking into getting hold of a lathe after being inspired by this project
im no expert on the lathe, mine was £300 its a C2A.

Starting on arm 2 now, from the shoulder down. I already did the pivot joint, so onto the upper arm.
this goes on the back of the big claw/minigun dealy
I struggled with an idea of where to begin on this, when I look at the picture I try to break it down into its component pieces. Problem is this is quite complex and im almost at my limit of what I can imagine.
This is the real thing for reference:
so a lot to think about there.....ive started with a block
started as I usually do by drawing a naff picture and filling in a load of dimensions that I make up. From this I decide to start with the rod things on the back

I hope you don't sell it, it will be too awesome to sell
Hand crafted robot like this, seeing all the work you've put into it, I reckon it would be worth a few £k to the right person. It'll be a totally unique piece of awesomeness.
Thank you all again
I have had a lot of emails, some form people I have heard of and a few about buying the finished item, I will sell it if I get an offer in the region of 30k.
One of the problems with spending a year on a project like this, is by the end i'll be sick of the sight of it.

Got everything attached to this blck now, cut a slant on it too.
cut a piece for the end, curves, took a chunk out the thin end and put a slightly larger semi circle in. Held in place by my large hydraulic fitting.
this too ages, lots of work here and very small, so much so my camera cant focus on it! the tiny brass hex heads are about 2mm across
crap picture but you get the idea

Added the collars on the large rod, also a smaller collar and a spring thing.
turned this on the lathe
it sits on the back of the gun and is the drum of ammo. the basic shape was easy enough to turn then I had to mark out 8 segments and mill a half moon out of each section.
next bit, no idea what it is
careful milling here, I will in time buff out all the machine marks
after some thinking and another awesome diagram (this one actually quite legible) I started on the fist that houses the big claw. Using delrin for this shape and using what I like to call "precision guesswork"
bit more shaping and filing
carefully hollowing the inside out, very hard to clamp in the vice now for milling.
marking out where to drill for the studs.

I havnt, it would take a while to fit everything together, time better spent working on new stuff in my mind. I will have to have a partial assembly after the gun arm is done. Im paranoid its all going to be out of proportion
i think the piece you're unsure about, this one:
http://www.ukmonsters.co.uk/robocain/DSC08965.JPG
is the mount that would allow the minigun to tilt on the Y Axis. it's either double sided (one on each side of the minigun) or single-sided, and also swivels in the X axis too
yeh........ i see that but it doesnt move in the film I dont think. Anyway its on there, there is only one on the outside.

Thanks guys
mounted the ammo wheel thing and made a checkered plate and another panel to go over the top
M2 was too small and the m3's were just a bit too big so I turned the heads down a bit, they look a bit funny because of the colour difference but im sure the size is correct now.
made 4 more fittings, 5mm and the tiny 4mm ont he right, this arm alone has something like 12 hydraulic fittings on it!
the 2 tiny ones attached, also the plate being held inplace by the tiny brass hex head bolts, 2 more to go in there.
mock up assembly next to the naff koto model arm!

Im using delrin for parts that I cant make out of metal, its mainly the parts that on the real puppet are made of urethene, the dark grey bits.

Working on the claw now,
sits snug in here
pivot joint
with a swivel on it
very carefully cut these pieces, always a lot harder when you have to do 2 exaclty the same.
then trimmed the middle out.

Rounded these pieces off, drilled a 3mm hole and attached to the main... thing with a 3mm shaft.
drilled tiny 1.7mm holes in the sides of them, tapped to M2 and put little screws in the hold them against the shaft. I will use M2 grub screws, I have ordered some.
parts for the thumb
the 2 fingers
quite hard to make these, they are slanted on 4 sides so had to hold them in the vice with the peg that they pivot on and then rotate the vice to get the angles.
drilled them through and checked movement
and the little thumb, same process, all drilled and taped. Had to counter sink the finger screw slightly to get the right look
now spend best part of half an hour using fine grit paper to rub the machining marks off the ally to achive that satin finish, so they look smooth.
I dont often blow my own trumpet, but im very proud of this picture and the likeness to the real thing
