This forum my last hope?

Greetings everyone,

I've found a source for the gears I need. They use set screws or as the English apparently term them, grub screws. But my Maxon motor has no flat on the shaft and is meant to accept press fit pinions as far as I can tell. The shaft is hardened to a Rockwell designated number so creating a flat might be difficult. Have the folks on this forum deal with this problem before?

The source by the way is RW Racing, Mr. Neil Stubbington. Here's the link:

Thanks,
Tom
