I now have two cars here, and I've got the measurements! I am ready to start cutting out the wheels. It will be easiest to do them if I do a larger run.

The process for cutting out the wheels requires me to set up my CNC mill in multiple configurations.



26 or 31mm widths. The tires these are designed for are the HPI vintage tires. If you'd like to run a different set, PM me or post here.


Here are a couple of teaser pics. The chunk missing was a glitch in the code, but has been resolved in the PC simulations.

Wonder how fast our little mori would make those parts? 40,000 rpm and capable of 1000ipm in full 3d mode, holding 1micron tolerance. Fast little die mold machine.

Want to find out?

Does the Mori have an auto tool changer? That one sounds like it could be fun to play with... The HAAS only goes 7500rpm spindle speed... but you already knew that.

We hit one of the wheels at 1100ipm with the 3/8 endmill for roughing and made a nice aluminum 'sculpture'. That was chalked up as a 'learning experience' for editing code on the mill monitor. Somehow the line that said 'F35.5234' got deleted while taking out a 4 minute session of the bit spiraling above the part and not cutting anything.


@Rick;

Yeah! Thank you. (IMG:style_emoticons/default/smile.gif) I am stoked! The owner is a buddy that worked with my dad when I was in high school. He is Very easy to work with and lets me make my own 914 parts. (IMG:style_emoticons/default/biggrin.gif) (for the real car, not just the little ones)

Sure does, 20 tool. HSK tooling, 10GB program storage, ESPRIT 3D cad/Cam software built in, high speed contour control, conversational programming, twin motors and ballscrews for each axis, twin SONY .01Um scales on each axis. Only 5.9" travel in x and y axis. Tiny smoking fast machine. If you want, send me the HAAS code and i'll throw it in the simulator of the control and see how fast it'll go.

BTW, this tiny machine was more than a nice house in most parts of the country!

Fairly new machine! I like that control, it's pretty easy. We ordered a haas, no tool changer. Ripped the spindle out of it, spindle motor, enclosure, modified it a wee bit and am now waiting for the 400 watt laser to get here.

can you email pics of the spindle motor and spindle? to my jimmc914 (at) gmail account... major eye candy. lol

what kind of laser are you installing in place of it?
somewhere down the road I'd like to play with that sort of thing on my router table. I've got some links for later that have DIY style stuff to convert it.
