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? Attached image(s) |

OK, now I need help.
I've found different options for collets to replace the drill chuck. I've got a 3/8 - 16 draw bar. There are these: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...e=STRK:MEWAX:IT But how do I 'clamp' with them? Then there are the ER32 and ER25 MT2 collet holders from Hong Kong: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...e=STRK:MEWAX:IT http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...e=STRK:MEWAX:IT along with the collet sets: http://cgi.ebay.com/SHARS-PRECISION-ER32-C...=item518cbbf19f Which is the best way to go? (I'm open to links from other sources, also) |

(I'm open to links from other sources, also) Ok, ER is a STD collet now days, where a MT (morse taper)2 is not. However, you would need to clamp a ER in a MT2, since that is what your machine is designed for. I would go with MT2 collets for what you are doing. The drawbar just threads in to the back of the collet and sucks it up in to the spindle. The taper on the OD of the collet will "crimp" the cutting tool and hold it very well. |
