Before we apply power, we use a hex hub to reverse-drive the motor by hand. If there's any binding or chattering, we disassemble and reassemble. It should be smooth-running in both directions (caveat - we've only done 2-stage, up to 49:1).

I haven't actually assembled any myself, but I'll try to oversee the next time one gets put together and pass this on in case they've been doing it sloppily. Thanks.
