Robocain custom build

[droutmaster]

oh man thats gonna be huge

[jessedart]

Dude this is AMAZING! My hat is off to you; outstanding job, Sir!

[xiombarg]

I just can't believe how much precision you achieve for such a complex build, and all from photo reference! Insane man. You my friend should be working for a movie studio.

[candyman]

Thanks guys, I appreciate the continued support!

2 arms down, 2 to go!

Turned the 2 shoulder joints, these fit to the shoulder disks.



cut and shaped to look as close to the picture as I can get



then the end cut flat, drilled and a pin mounted on the disk.

Bro, you're truly inspiring me to start some custom projects;
but not on such a grand scale as This. (Me = Wimp) ;D

I'll stick to silicone, rubber, plastics, and resins.
This week I've started gathering all my moldmaking and
casting supplies and materials.

I really like how you're machining all these parts; and now
you've come to my favorite part: Joints.
I plan on casting large joints, similar to the revoltech
joints designs; also some trial ball-sockets and ratchet
joint systems. I'm using my DoGA CGA to design 3D
models of my joints... then I'll try to import them as
STL files for Shapeways to make me some of these
as plastic templates for their molds.
For now, my concepts are all in my head and I think
about them day and night where ever I go.
Moldmaking and Casting: it's my first time, and I'm
a novice at it, just starting out.
But, whatever successfully becomes of it, I owe it all
to You and many other crafty RJ members here,
as my way of saying Thanks for sharing this project
experience with us.

Pilder On!

good, glad I can motivate!



better make 2 of these



and one of these



decided to finish off the shoulder cover from the 2nd arm, i forgot about that





back to the 3rd arm



and all fitted together you see where im going with this

[magengar]

Precision at it's Finest ever!

Got it fitted up and attached to the shoulder disk



cut 2 blocks for the next parts and turned some disks



spent a bit of time rubbing everything down with 600 gritt to get that satin smooth finish. Most of the other parts ive done I havnt bothered yet but I wanted to do this arm as it would be on the finished model, most of the aluminium will look like this. This arm is tough to make as the original is just a piece of molded plastic so I have to think up ways of joining the parts together without visable screws etc.

again this was hard to do, the tiny screws not real on the puppet, mine using tiny tiny M1.6 mm screws and nuts.



attached, note they are on both sides,


counter sinking holes so the screws, again M1.6, sit flush with the surface.



making another 1 or 2 of these parts, had to use the slitting saw to carefully cut the slot



2 more, nearly done in their pre-rubbed down state.

[droutmaster]

hmmm i wonder how you are gonna make the head.

[candyman]

funny, I was wondering that too

sunk the tiny screws into the clamp joint parts



had to make some odd parts and disks etc to join everything together



realised it was too short so had a re-design and spaced it out a bit more, this section will be covered so it doesnt need to be as detailed.



This arm has the spot welder thing on it, hard to know where to start on such a complex lump, so after some thought and a lot of measuring im quite happy with this



looks about the right size to me, trim the middle out



and the top, sitting on another turner prize of a diagram that looks like a cross between a babies rattle and a policeman hiding behind a tomb stone



carefully recessed the edges and drilled through so they lign up top and bottom.

[droutmaster]

so where the block piece go exactly?

[candyman]

you can see in the top pic here:

ok cut a groove around the middle and found a good imitation of the stripe around the middle, a cable tie!



more trimming and recessing, here and there



top part



using the end I made earlier, made the small part that will hold the bottom of the ram and cut that top part to shape.

[magengar]

Coolness! I always imagined the ol' cable tie could
be of Some use, but I never imagined it used This way.
Genius!
Raw recycleable materials like plastics and other odd thingies
(like tubes, bottle caps, cassette spools, and yes Cable Ties...)
can go a long way in this aspect of this hobby.

Rock On!

tis true! a secret I will let you in on on my alpine gun, at the time I didnt have a lathe and I made the adjuster wheels in the stock from plastic milk bottle tops filled with resin! here:

I thought a lot about the arms of the welder, the originals are solid moulded pieces, I eventually settled on this design, when you only have to make one its not so bad to shape it by hand, its when you have to make 2 or 4 the same that this is the harder option.



attached and trimmed to size, needs a hole in it for the electrode oart and the whole thing blending and filing



yeh?

[magengar]

I hear ya... making just ONE of something is easy.
But making identical pairs (especially Left and Right)
is very challenging if they're made by hand.
Opposite parts have to be mirrored asymetorically
correct or else one side will look weirder than the other.

Man, that's it, I'm commending myself into a nursing home
right Now... I can't believe all the GENIUS tricks and mods
I've seen thus far (VERY Genius using Bottlecaps as Adjuster
wheels for your alpine gun!) using scrap recycled plastic
odds and ends. I never would've thought of such things.
Dude, I kiss the workshop floor you stand on!

Fan Request:

Admin! Mods! Eunochs! and Handmaids!.....
We need a "Robot-Japan Fan Art and Customs HALL OF FAME"
built right here at the RJ website, and I want this member
and his project inducted, A-S-A-2-da-Peeeeeeeeee!
And each year induct other member's awesome works.

If not a Hall Of Fame, then at least an annual

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.

[magengar]

Wow, I luv how you're using Plastisol for that "light"
thingy on the shoulder there... an LED light with a hearing-aid
battery would definitly make this custom Screeeeam!

[Kidchuckle]

holy crap the process is awesome!!!! seeing the progress is very exciting. and the craftmanship rocks!

[candyman]

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

[acturus]

Just amazing!!!

the feel i get is that you just need to pass current in there and it will start moving by itself.


ITS ALIVE, ALLLLIIIVVVVVEEEE!
