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.

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.

The process, for those that are curious:

Step one, chop up the stick of 2inch aluminum into inch and a half long chunks. - 2 hours.

(Dial in vice on rotary table to be centered with spindle) - half an hour, 45 minutes. Requires dial indicator.

Step two: Face the chunks/machine one face square and mark it. - 10 minutes per wheel.

Step three: Face other side of chunks/machine down to size. (1.125 for narrow wheels, 1.25 for wide wheels. - 10 to 15 minutes per wheel

Step four: Rough out the fronts of each wheel. (I'll put a spacer between the bottom of the vice and the wheel so that the same code can be used for narrow and wide wheels and run all of them through at once) - 35 to 45 minutes per wheel

Step five: Rough out the backs of the wide wheels - 35 to 45 minutes per wheel

Step six: Rough out the backs of the narrow wheels - 30 to 35 minutes per wheel

step seven: Run the finishing script for the backs of the Wide wheels - 15 minutes per wheel

step eight: run the finishing script for the backs of the narrow wheels. (finishes the 'hex' for the drive nut) 15 minutes per wheel

Step nine: Run the script for the 3d portion of the fronts of the wheels. (the part that makes them have 'the look') - hour and a half per wheel (working on making this take less time)

(now I set the machine up with the rotary table being vertical, with out the vice. I'll have a fixture to bolt the wheels to, and it will be dialed in centered on the rotary table)

Step ten: Run the script for each wheel for the area that the tire mounts. 10 to 15 minutes per wheel.

Step eleven: Put a couple of sets of wheels in the polisher for over night. The polisher has walnut shells and rouge. - one to two nights.
