Robocain - Robocop 2 robot

[Building Candy]

Yeh I tend to quote most jobs at between £10-£30 an hour depending on the complexity. In some cases things turn out much easier than expected, or harder.

This, however, is a challenge for me. I couldnt have made this a couple of years ago, only finishing the DSR1 and the rifle stock I did has given me confidence to try this. It would have to be a 5 figure sum to part with Cain.

Building Candy - Where did you learn to do this? Did you do "NVQ 2 Performing Engineering Operations" by any chance?

a what what what? no I have never studied engineering, or ever done a course or even been to university for that matter im afraid. I just started making rc truck chassis about 6 years ago, then 2 years later onto the guns and now this. I think im getting better with every day that passes, certianly 3 years ago I would never have concidered this project. When I finished the dsr1 I felt like I could make anything and do anything, thats why im doing this. Im lucky to have a natural talent for this although im sure my own brand of self taught engineering would probably have a "proper" engineer cringing at some of my methods and techniques!

How much for a DSR1 replica? Don't need the scope as I've got a nice Leupold vari-xiii from my target shooting days.

I wouldnt sell this DSR and to make another would be tough, im not sure I could give it the same attention to detail. I have thought about selling them when people offer large sums of money, but money is money, you can always make more money. These guns are 1 off, if I sold it, it would be gone forever and thats not something I want to do.

Its no good, ive got to post the DSR pic! im so proud of it!

im gonna have to get it out and hug it now!

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

Back to Cain, onto the waist/torso,

bit of guess work here, hard to estimate the shape and size of the plate.

trimmed and rounded

...after looking at the pics again i decided this is too thick

so took 1mm off the top and put the holes in it. Picture in the background for reference.

used a slitting saw to cut the slots

onto the big lump in the middle

this looks a bit big too..... hmm

might end up taking it down a bit, be glad to get this stupid bit out the way!

im struggling to see the parts on this plate, a lot of it is molded and im not going to do it exactly as it'll be all but covered by the cylinders and all the pipes and wires. So:

i'll have to fill all the gaps before painting, most of it will be covered anyway

onto the little U brackets fo the cylinders, I have to make 8 of these all exactly the same.

cop them all off

mill each one to the same size, both ends, boooooring

then file the curve on each one exactly the same.... booooooooooooring

then mill the gap out......... STILL boring

 

[Building Candy]

can you write ocuk on a piece of paper and show it next to your creations plz.

lol, serious? you want bread too? im not sure I have hovis

 

[Building Candy]

Thanks for the continued kind words and support guys!

If i had the cash i'd make you an offer you simply couldn't refuse.

Yeh i hope one day an oil barron will visit me with his cheque book.

Not sure if anyone has asked you this yet but what will be your next project or what other project are you wanting to do?

I have about 800 hours more to do, I need to remain focused on this for the moment and not let my mind wander.

Weird coincidence; just got back in from dropping the missus of at work (Equality gotta luv it. ) last song I heard on the radio (2) was "The Candyman" sang by Sammy Davis Jr.

lol someone once sent me the video from charlie and the chocolate factory with gene wilder(?) singing that!

Get the bread out

You ask, you get:

 

[Building Candy]

AOD has said nothing but fact, well done.

As my guns are based on an existing weapon its classed as a modification to that weapon, like a big body kit if you will.

yes the barrels extend as far as the outer barrel allows, I have a chrono they are all bellow 500fps.

 

[Building Candy]

Well an hour later. The gap is only 3mm so I have to cut 10mm (i think) down using a 3mm cuttter, the 3mm mill is quite delicate so I

have to take light cuts so as not to clog the cutter. So something like .3mm per cut, so thats 30 passes per U bracket, times 8 brackets

is.... tum tee tum 240 passes.

now drilled them all sides and bottom

got some material for the cylinders.... im not 100% on this, it looks a bit thin, the detail on the cylinders is crazy, im not sure there

is enough room

turing away

cutting the rod first for a trial fit

cylinder

oh dear my initial suspisions are realised , after adding the 4 screws there is no material for the 2 verticle screws and it does look

too small, which I suppose is a good thing.

pic of the real thing for reference:

while I wait for thicker rod to be delivered i'll get on with a left leg bit.

a lot easier with one to copy

finishing off the other thigh

cold up the garage the other night, didnt help the gas in my heater ran out brrrrrrrrrr

easy when there is a part to copy

center it up with a little pointer i made.

then take it round

nearly there, just the easy bits to do.

boring the holes in the sides and drilling and tapping everything

turned the other spacer and there we are

gave myself a big pat on the back for getting this hard bit out the way for good.

 

[Building Candy]

thanks

Ok got the material for the cylinders, this "feels" right, progress will apear slow on these for 2 reasons. 1, I have to do 4 of these the same, so each operation has to be replicated 4 times and 2 I have to make a note of every measurement so I can get each one exactly the same.

drilled a deep hole for the rod to move in.

put the 2 steps in.

one thing I learnt from the 1st one I did wrong is that no matter how carefully you clamp it your gonna get marks, so I am purposfully using a piece of rod that is 1mm too fat, then ignoring the extra 1mm (0.5 each side) in my measurements, so at the end I will have a finished cylinder that I can then turn down for a perfect finish.

for scale the milling cutter here is 3mm

all done here, 4 x 3mm countersinks with 1.7mm holes per cylinder AND the 2 verticle holes that I couldnt fit before.

cutting the flat on the other end

taking off the additional 0.5 form the ends and 1 or 1.5 I cant remeber form the middle of the cylinder to leave the flawless (hopefully) finish.

 

[Building Candy]

Not sure yet, probably just painting, duraility wont be an issue it not like its going to be handled....... ever

Thanks again for the praise from you all, its a great help .

main bits done and all the same,

one of the 4 rods, had to start with 8mm rod then turn the whole length down to 6mm and test fit in the cylinders until it was perfect, then trim the 8mm end and round it off

the m2 screws are still a bit too big to fit so I had to turn the heads down from 3.7mm to 3mm so they sit in the recess. 6 per cylinder, 24 screws to turn down.

then tap all 24 holes with M2 thread and were starting to look like it

then whilst drilling one of the U brackets I did somthing silly and took another whack on my previously damaged thumb, good grief, thats enough for today i think

 

[Building Candy]

Anymore updates?

of course

I managed to get the right screws for the U brackets

had to drill, tap and recess each one

...and finish the other rods off, I have also put a tiny line where the rod meets the flat bit, too shallow to see here really.

first one drilled and in, still a bit of work to do on the cylinders yet, I need to make the high pressure pipe work.

 

[Building Candy]

Cut a very thin strip of metal, only 3.5mm across, then had to cut a bevel in the top, did this by wrapping a rod in sandpaper and carefully rubbing away at it.

next had to trim 8 of these into this shape then drill them and countersink, no mean feat, I can hardly hold them!

needless to say the M2 flathead screws where a bit too big, so I had to carefully turn all thoses down too.

One installed, used a piece of 1.5mm wire for the pipe

and another set of fittings for the pipework

and attached.

Thats pretty much job done on these, im glad I didnt screw anything up

 

[Building Candy]

You’re doing a fantastic job.
How far through the project are you now?

Im not sure, maybe 20%

ive just had a good read though the 7 pages while trying to look productive at work on monday morning :/

Very nice work. Im always impressed by someone who is self taught. You should offer yourself to do some commision work rather than recreating something you have already done!

How long untill we can see the bottom half stoodup by its self? or does it not work like that ?

I do commision work, over the years I have made all sorts of things for people.

I HOPE this will be done by the end of the year, 8 more months..... fingers crossed.

It only has 1 leg so standing it up is a no go at the moment, plus it takes time to assemble it all and I want to spend all my time working on it rather than playing with it...... ooo eerr

 

[Building Candy]

This is going to be hard for a bit..... im even breaking out the cardboard, just about reached the limit of what I can do in my head.

first up the plate to conect all the rams in the body, this is all guess work as you cant really tell from the pics whats going on

decided to knock that out of metal but i think its a bit short.......

trying to estimate the sizes and angles of the shouler fixing points, its like a rubix cube, you get it looking good from 2 angles then look from the top and its wrong!

made some heavy duty mounts out of metal

started making the main parts up and fitting them into the "skeleton" very wrong on some places, need to extend the main chassis

pushed the front pistons further forward and then re calculated the position of everything, it looks beter, but still spent a few hours moving everything around.

made a start on a simple bit

also realised the plate is not flat but tilted up at the front so mounting it higher up and again recalculating for the position of everything.

 

[Building Candy]

To be honest this is a real big challenge, im struggling through it.

section above the door thing

the screws in this are very small, ive ordered some.

I tried to make the inside of where the trap door goes by bending a thin bit of metal to shape..... but it looked and felt crap, so im doing it the hard way.

took forever to mill the inside out, put the angles on it and milled a recess for the bit I made earlier to sit on it (this is the back of it)

 

[Building Candy]

drilled through the box thing and made a pin to pivot it on, took ages to get it to close flush

made some mounting points at the back to screw it to the mounting plate

and decided to cut a fresh plate out this one has been modified one time too many.

starting on the chest, looking like a big washing machine drum

realised after cutting the big disk that it just wasnt big enough, looks wrong to the pics

so ended up making a slightly larger one

profile....

 

[Building Candy]

Well im in Florida this week but you'll be pleased to know I kept some updates back so you dont get Cain withdrawal! good thinking huh

I recessed where all the screws sit with a 3mm mill then drilled and tapped them, turned the screws down too.

Next I made a pair of these blocks on a slight angle that will go into the back of the drum and allow them to be adjusted a bit and then held in place

something like that

on to the other side, turned more or less the same size with some beveling and recesses

it needs a U shaped piece on the front of it, after a bit of thought I decided just to do it by hand. Its only a 1 off and by the time I'd setup the rotary table and clamped such a small piece down I could have made it.

something like that

bolt it on for a trial fit

next back to the delrin for the cover that goes on the chest

after fixing the "U" on I milled out room for the cover.

and that sits in there nice

 

[Building Candy]

Thank you all for the kind words

 

[Building Candy]

Ok starting on the pipework, turned some pieces up and then milled a flat on them to get them to sit right, bit of trial and error here.

as for fixing it all together im drilling and then screwing in from the middle of the dude .. in the middle.

trial fit , something like that

not a bad likeness

more turned rod then I had to to swing on it to bend it.

one each side slots between everything, this took ages to get right so it slotted into place with no gaps.

looks ok I think

 

[Building Candy]

lol yeh, if someone offered £1k i'd say "no, but i'll give you double if you can make me one" kinda puts thing in perspective.

 

[Building Candy]

im back in the UK now, when I have adjusted to UK life again cain progress will resume at the normal rate.

had to turn these screw heads down a lot to fit.

they fit in there, I have ordered some even smaller screws for the other 4 holes.

drilled , tapped and put screws in these "collars"

trial fit with pistons attached, the angle of this photo was taken head on quite close and makes it look narrower than I think it really is, after looking at all the pictures im quite happy with the position of everything.

all that to one side for now, I need to work on the positioning and mounting for the shoulders.

these will form the sides of the chest, the shoulders will butt up to these, I was thinking about only having 1 axis of movement for the shoulders, up and down, but in the film when they reveal cain at the press conference he drops his shoulders down and back. So I am working in 2 axis, also with it needing t sit flush at rest it also needs to move in and out, so the full 3 axis of movement is required. Oh yeh and they rotate as well, depending on what set of arms he wants to use.

after a lot of trial fitting I decided the plate didnt go far enough back so I have added an aditional plate on the back and moved everything back a bit.

back to the cardboard, the placement of everything looks right now from all 3 angles.

 

[Building Candy]

one lump of 6mm plate, tough stuff this, anyone want to hacksaw 4 circles out for me?

ok i'll do it then, this is with the distraction of my dad nearly setting fire to the "curtain" partition I put up in the garage to keep his dust out of my build area!

hacked out rough then spun on the lathe, my lathe isnt really big enough to turn pieces this big so I had to improvise.

Now we will have a leason in making little pipe fittings, if in doubt make some fittings, i'll be needing a lot of them!

turn 6mm down to 5mm and step the end to 4mm

centre drill, then drill the rod with a 2mm hole

cut the piece off and face the rough end, fit in vice and mill with a 4mm cutter a half moon.

turn and face another piece of 4mm with a 2mm hole in it, making it 5mm tall

make LOTS of these, drill a 1.7mm hole in the side of the last piece and tap M2 thread, then countersink the top of it with a 3.5 drill/mill so the screw will sit inside it a bit.

then assemble it

... the rest too

and after a few hours careful work you have another eight 4mm fittings.
