For Christmas I scored a Jet Hobby Mill to go with all of my stepper motors and CAD-CAM software and 3-d scanner.

I still need to get the correct collet and end mills; but I'm quite excited to get started machining some parts.


Does anyone have a 914 emblem I can borrow? Someone was wanting a 914-8 machined, and I need a 914 to scan and model to get to cutting out some aluminum parts.


Also; does anyone have an R/C 914 setup? I'm planning on machining the Fuchs wheels out of aluminum and need someone to help me out with getting the offset and diameter just right.


I'm also thinking of machining a 914-World emblem for the backs of our cars out of aluminum. If I do go for that, I'll snail one off to Eric first, get his opinion and stamp of approval.


I've been studying online all of this stuff on CNC and machining and am quite excited to actually get going with some 'on hands' stuff!

Any other suggestions, for things to carve out of some aluminum?

I will send you these wheels after the Build Off. I'm going to bring it to the Build Off for AX compitition. These are the closest I could find to Fuch wheels.

Oh! and I have another project for you. Brass 918-S script for my tail light panel.

And I need an aluminum plaque made for the Shealey.

What collets do you need? R-8 MT, ER. I have 30 Cat50 holders in my dining room right now. I may have what you need. ( I know its not a CT machine, and the 50 taper is bigger than the whole head on that!) And I MAY have some end mills left in my old machinist box. Let me know.

ooh oooh... awesome; thank you for all of the help, guys!

Rick, same font as normal 914 emblems? And thanks for the wheel set loan! Are they a good offset? We'll have much closer than that by the time I get done playing. (IMG:style_emoticons/default/biggrin.gif)


Mr. underthetire; This mill takes MT2 style stuff. It's definitely small!
I'd like a few different shapes to get started with on the end mills. A ball headed one or two, a corner rounder or two, and then square nosed. I can adapt spindle speed to number of flutes and materials.

I think I need hold down clamps as well. I haven't had a chance to check it all out yet. it showed up an hour before I went into surgery, and my dad unpacked it and set it up in his shop for me. He sent me that particular pic as well. I haven't even plugged it in yet. My excitement is growing. (IMG:style_emoticons/default/biggrin.gif) thanks again!

very sweet dude I was thinking of getting a mill also ,just because I'm always making something more like things that I can use when I'm shooting.(camera) stuff But I never used one and don't know what to buy for (tools) or bits?

I have an original 914 & 2.0 rear script off a '74 that I could let you borrow, in addition to a set of unmounted R/C wheels exactly like the ones Rick suggested. (as long as I'm second in line for R/C fuchs wheels - assuming you are first :wink:) I'll even ship them to you with a return box!

edit: email me and I can ship them out this weekend...

If you are going to CAD/CAM it how about having them scanned in 3D? I might know someone local with a 3D scanner?

Good luck with the scan.

So far I've tried it three times, and have been underwhemed.

Once with a point cloud on silicone gastric bands,

Once with white light on a really tiny steel part,

Once with x-rays on the tiny steel part.

It's sorta close and straight lines aren't always straight so you have to redraw/rebuild in 3-D CAD.

With the gastric bands I ended up using a grid pattern and a caliper, and cuting the parts in pieces to get the cross sections. That finally get it right.

What kind of 3D scanner? Maker?

MT2 is not something I would have, my small tiny stuff is swiss collets. So, you want a ball mill, a chamfer tool, and a center cut. I would assume two flute for aluminum. I might have some 1/4 inch stuff, not sure if I have high speed steel. Most of my small stuff was carbide, and I would not use carbide until you figure out how rigid that machine/collet set up is. I'll take a gander tonight.

I think it was 3D Scanning.

It was a German system and they even sent our part to Germany and the system designers couldn't do it either.

I have an original Next Engine Scanner and a full size 16x7 Fuchs (a whole set of them, actually...) that I can scan.

For the scripts; the plan is to take a picture over head, straight on, and then trace around them with the vector pen tool, then export to a file that bobcad can import.
They are just 2D with rounded over edges... (and the area where the digits are held together is just another lower level of machining)

Wow, you guys are awesome.
If you need the 914 emblem I can loan one to you, sounds like one is on the way though... please put me on the list for anything you make up regarding the
914-8
918S
or anything like that.
Thanks for your efforts on our behalf.

Can you educatem me a little on the necessities of rigidity with the carbide bits? HSS vs carbide? Could I not still control spindle speed and plunge speed if the machine isn't stout enough to handle fast?

hmm.. yes. ball mill, chamfer tool, and center cut. =o) I think using those terms I might be able to find more bits for purchase from vendors as well. Thank you again!

OK, sounds like you have a set of wheels coming. That's cool.

Yes, 918-S same font as the Porsche script. I would send you mine off my tail panel except I sent to another guy that was going to make me one from composite and cover it in gold leaf about 5 years ago... So, that's why I don't have a script on my tail panel.

PM me your address, I will send you a piece of brass for the 914 and a piece of aluminum with the info for the script for the Shealey.
