For the MIT Motorsports MY24 Car, I was tasked with machining various components for the Powertrain system. Over the course of about 100 hours, I used NX CAM, a HAAS VF2 CNC mill, and a Prototrak manual lathe to machine the differential mounting plates, eccentrics, and Motor hub.

These eccentrics allow us to adjust chain tension easily.

The second operation.

The bearing press-fit hole was dialed in .001 inches at a time.

This plate attaches the differential to the car frame via the eccentrics.

Each hole had to be precisely dialed in .001" at a time for precise slip and press fits.

I created a custom jig to locate the plate for the second operation precisely. This jig was a perfect slip-fit for the plate.

Perfect slipfit!

The motor hub allowed us to attach a sprocket to the motor as well as support it.

I did the first operation on a manual lathe.

Bearing and sprocket surfaces were dialed in to be perfect slip fits.

Second operation was done on the VF2.
