Started by center drilling the piece of motor shaft. I had previously attempted to heat the rotor and remove it without any luck. It was galled badly.
|
Drilled out.
|
Bored the shaft until just a thin sliver remained.
|
|
|
|
Pulled the remnants out with some pliers.
|
After boring you can see the stress around the shaft area.
|
This shows the top side.

Wrote a quick program to machine the taper into the bottom side of the rotor. Note that this rotor will ride a 0.50" higher than our standard mount. This old center was too small to accommodate the recess.
|
Changed the jaws and flipped the part to machine the top side along with the o-ring groove for our custom nut.
|
Installed the custom nut and o-ring. Ready to test.
|
|
|
|
Installed on the machine and test spinning.
