2nd "arm" not so easy, after a bit of thinking I decided to make it like this

had to cut the slot in the tube with the slitting saw.

at last a fun bit! little hydraulic ram

detailed, drilled and then the rod to fit

tiny screws, tiny holes and a tiny bracket

in other news, found some corrugated plastic which looks ideal for the shoulder thingies

i originally though it had a light behind it, but its the flash from the photo, thank god

had to make a number of little hydraulic pipe fittings again, all attached holes drilled and taped. Just the finishing off to do now, some detail here and there.

A lot of it wont be painted, like this whole arm is silver on the real thing so it'll remain raw aluminium. The gun will be the only detaled part that will have to be black i think.

Just browsing the other forums you have logged this work on and there is a bit about you not being able to hide wires for working the lamps. Im sure you could manage that. Couldnt you just use LED's? I am sure you only need very thin wires and a small battery to power them!!

It would be great to see them working....

The wires would still be visable, besides the lights are only on for the warehouse scene. I think it'll look silly with big spot lights stuck on it when its not dark.

Ok back to it.

take one block of delrin, cut it square

remove 80% of it

mill a funky recess

drill, countersink etc etc

got some 3mm brass tube which is spot on fer these bits, managed to tap the inside to M2 for the bolt head M2 screws to hold it in.

spot on

3mm rod tapped to M2, so thats about a gnats-whisker of actual material left in place?

someones paying attention! yes, chuff all, actually i think it was 3.2mm, but still thin!

have you an estimate on the models finished weight?

not really, 5kg maybe, dont know

Nice update, when do you think it will be finished?
Thanks
Jay

It will be finished by christmas

That will have a really good weight to it.

I take it that this is for yourself?

Full sized motorised one next?

Its for me unless I get a really good offer

Building Candy · 28 Sep 2010 at 23:21

hello mate

turned some disks

trimmed, cut, drilled, counter sunk, tapped etc

using my swivel vice to get the angels for this bit

Building Candy · 29 Sep 2010 at 10:15

Thanks, I try to take pics every 45 minutes or so, I think any more frequently and i'd end up with 1000's of pics!

Building Candy · 3 Oct 2010 at 10:08

another one finished

all assembled

turned some collars/disks to mount this on the end, the pincer will go on the end.

start of the pincer

the pivoting points of the pincer will attach to this, its pretty small!

Building Candy · 9 Oct 2010 at 15:40

Starting on the nippers, have to make 2 exactly the same which is always a challenge.

marked everything out and cut a groove each side with the bull nose cutter.

bit more trimming

bit more trimming, wobbly photo sorry

basic shape done on a picture of what im aiming for.

Building Candy · 10 Oct 2010 at 17:27

Cut the angle on each side on each one (look like little fish)

started rubbing one down, 600 gritt gets the right finish

found the mod 1 gear track I used for the shoulder disks is just right for the teeth! excellent, one less thing to make!

made a set of these ovals up only to find they were the wrong size

turned the little hydraulic cylinders things

thats the idea, just too short

just to give an idea of the size

put together with the short plates on, it opens at an angle becuase they are too short, better remake them then!

finally the right length, rubbed down, teeth painted, looking cool

nom nom nom

I've loved this thread for quite some time.

Im assuming once it's built up you'll tweak and improve it until you're satisfied?

yeh just getting all the hard stuff done first, then i'll have to go back over everything making sure its perfect, then painting some bits, polishing others, then pipework, hydraulic lines, etc.

Building Candy · 14 Oct 2010 at 21:55

onto the armour.

milled a recess out

cut the middle out

chamfered a curve

that'll fit just about there

M2 hex head bolts,

Building Candy · 16 Oct 2010 at 17:05

Had to do yet more little hydraulic fittings

attached and curled up

I need to build up the collar, to where it meets the head.

Building Candy · 16 Oct 2010 at 18:02

well spotted, im probably leaving that bit off, i dont like it

In that case can you re-do the thighs? . Always thought the legs on the original were awful.

lol, no I like them, plus that was code for "that bits rather hard to do so im leaving it off!" down to the original being plastic not metal.

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

Keep forgetting to update, sorry.

Onto the head, back to the cardboard as this is a fairly difficult shape to scale from pictures.

The basic shape here:

but i think overall a bit to big, maybe 20%

so cut it and chopped it, making everything a little smaller, quick shot of paint

a better size, I spent a long time measuring and playing with cardboard, I think overall this is right.

starting with the top in delrin

this is for the front of the head, at the moment all a bit overwhelming as the task in hand is rather difficult. This is the final hurdle though, once over this its all easy.

something like that, its such a funny shape you only have to turn it a few degrees and it looks so different.

outstanding. are you still intending to put a small TFT inside the head? it looks like you've got just enough space for a 1.5" unit.

Yes I am, but at the moment no.
