Thank you for referring me to Tormek support, Ken. Tormek confirmed the drive wheel wobble and suggested the zinc wheel, which has tighter tolerances; but, wouldn't guarantee that it would completely correct the issue. Since this only affects the honing wheel, I'll probably just live with it. Now, that the the motor doesn't bounce (having sanded it true), it's not a big deal.

General Tormek Questions / Re: Drive wheel wobble

Thank you for your thoughtful replies. I posted my question before starting four weeks of travel, thus my slow response. I'll get back to this in a couple weeks.

General Tormek Questions / Drive wheel wobble
January 21, 2020, 04:06:00 AM
Has anyone had a drive wheel that wobbles side to side and replaced it? I wonder if it's worth the cash or not.
Background:
I bought a 2000 and accessories on a whim at an auction. In hindsight, what a great buy... I love its speed - much faster than running through up to 4 grits on DMT diamond plates. Also, the concave surface, makes touch up on those plates go much faster.
Anyway, the motor was bouncing and both the stone and the leather wheels were wobbling side to side. Without much investigation, I decided to upgrade the shaft, because it came with new bushings and everybody loves it anyway. After installing this and seeing no change, I started to look for the real problem, since it wasn't the bushing.
The motor was bouncing, so I trued the drive wheel with sandpaper to eliminate that related problem. However, the wobble persists, because the drive wheel wobbles (didn't think to measure how much). Since this is connected directly to the leather wheel, it seems there's no way to fix that. I played with shims for about an hour and gave up. Also, this wobble (for a reason that doesn't seem to make sense) is mimicked on the stone. I tried adjusting the stone (turning 1/4 turns on shaft and sanding bushing area flat) with no noticeable difference. Perhaps, there's enough flex in the frame to pass a 2mm (~1/16") wobble to the stone.
I look forward to learning about any similar experiences.
