1

Mill Racer Frame

Carve the main frame of the race car out of 1/2" material. This is the main functional piece of the car, so choose a durable material.

Use this EASEL link

2

Mill Racer Tires

Carve the tires out of the same material that you cut the racer frame. We kept these as a clean 3 spoke design, but you could add more or less detail to the spokes. You can also add grip to the outside or experiment with the size to get better results.

3

Rough cut the top of the racer

This is the start of the main aesthetic part of the car. Use an 1/8" ballnose endmill to carve out the rough shape of the racer.

4

Finish cut the top of the racer

Use the same 1/8" ballnose endmill and run this cut to clean up the previous step. The finish will still require sanding, but will be much closer.

5

Etch the number 5 into the hood

Switch to a 1/32" bit to etch the number 5 into the hood of your race car.

6

Cut the profile of the top of the racer

Use an 1/8" endmill to cut the profile of the racer and remove it from the machine.

7

Sand and Finish

Sand all parts to get a smooth surface and finish with mineral oil.

Assembly

For the axles we used 3mm rod that we cut to length. For the rear axle you can take a short piece and epoxy it in the center to create your catch for the rubber band.

The wheel wells we made using small hex nuts that we super-glued in place.

Once your bottom frame is all set up you can adhere the top piece and tires, Then you are ready to ride!

Very cool! What software are you using to create the 3D tool paths?

I tried twice to cut the top of the racer and ran into the same problem both times. At the same spot, the Carvey milled right through the body of the car and into an uncut area of the wood. You can see photos in the forum. https://discuss.inventables.com/t/cut-jumping-to-new-orientation/22022/3

When I'm trying to carve the #5, the path is too high-- its about an eighth of an inch off? Any ideas why that might occur? Thanks!

Cool design! When I open the rough cut and finish in Easel I get a cut preview only - no way to edit or move it. Is that intentional or is it me? The other parts open in Easel edit pane normally. Just getting started -any tips appreciated.
