Machining Endo Arm/with my twist on it.

[SXRDROCKS]

I welcome any input a machinist could give me,as I am still experimenting on how to make different parts.I'm working with a CNC lathe and milling machine.As of now I am wondering if I modifiy the design or go the course.I have made the fingertips in brass and find this very nice.Will keep putting up pictures as I go along.I'll do my best.BTW I put the connecting posts are not cut and press fit yet,it's just to give an idea.

Wow..where did you get the $$$$$ to buy a CNC mill&lathe?I don't remember how to program a CNC machine anymore:confused.They look like good, clean parts.Any reason why you are machining the tips in brass and not all in aluminum?

That's really cool and you can't go wrong with CNC. Say...where did you get your measurements from or did you just scale it down based on your hand size like you did on your pics? Or do you have a sideshow replica to take measurements? Thanks for sharing

I'm currently finnishing my two year training on CNC machines and have three months left.So i'm in a hurry to finnish this,drawing and writing code whenever I can.I got my measurements from many pics and yes... alot is based on my hand(got big hands like Arnold LOL!)Just thought the tips would look good in brass,and I think they do.

Hated G-code at first,love it now.I'll have a though time going back to conventional milling.lol

Are they table top models you have at home? I've seen small bench top CNC mills and lathes.Depending...they can be somewhere between $2,000-$6,000 if I recall. Would you ever be up to turning and milling small runs for parts...if so,what would be the fee?I honestly can't recall any of my G or M codes.Except for maybe G0...which meant "GOES FAST".Usually to the tool change position.

They are pretty huge machines,but thinking of getting a small conventional lathe and mill at home.I just want to work soft metals at home for fun.Maybe then I'll do parts for people.

Its hard to find small, table top conventional models.They are out there,but allot of the ones I've seen have been abused and not maintained correctly.The ways are shot/rusty,bearing are sloppy, worm screws are messed up and numberous tool wrecks into the table.Its a shame because those really old machines really are the best ones to use. I'd like to get a re-built horizonal mill/table top model with a vertical milling head attachment and a small tool lathe...like a South Bend would be awsome.Ideally I'd like to have a Monarch, but it be overkill for what I need to do&make. I found a web page that rebuilds Bridgeport Mills.I think the cost is around $5,000(minus tooling).Not a bad deal for a really nice mill.A mill like that and $2,000 of tooling and I'd be making some money for myself.

Update:Machined T-800 endo arm

Here are a few pics of my progress.The screws that are used are temporary and am waiting for the good ones(stainless steel) to arrive. I strayed a bit from the original movie design but am very happy with look.Hope you guys like this.
Alot of work still ahead.

Update pics on new thread.

Re: Update:Machined T-800 endo arm

oufff,had problems with my machine today.

 

[SXRDROCKS]

Had time to complete the fingers.I polished the metal and it is really smooth.Still have detailing work though,and waitng for the right screws to arrive.Next is the base plate where the thumb and finger supports and pistons come together.I already have a headach thinking about it.LOL

 

[SXRDROCKS]

Got a bit more work done.

Do you have a SS replica?
