I just received my Graves Preformer in todays mail.  After inspecting it, I am slightly disappointed in the motor assembly.  I purchased the motor since it was almost half the list price and if I would buy it later the shipping was almost $20.00.  I assembled the preformer and attached the motor.  After turning on the motor I found the motor shaft unscrews off of the dop shaft, an easy fix with a setscrew but I would have thought this should have been corrected way before this. Also the on/off switch is flaky, not a crisp switching. The spring clip used to hold the cam against the stop is too small to easily attach to the motor pin.  Also, if using the motor, you have to completely disassemble the unit to change cams.

The performer itself seems well made although it does not easily lend itself to being mounted on the left side of a verticle wheel.  The cam engagement is set up for operating on the right side and if you mount it on the left side you will not be able to adjust the pressure down into the wheel during the grinding process.

My recommendation, if you plan to purchase the performer, don't invest in the motor unit unless you plan to make the same shape cab in quantity.  If you plan to change the cams for different shape cabs, you are better off using the manual version.
