My new T-8 has a fair amount of wobble in the drive wheel and I'm wondering if that's normal, or if perhaps my shaft isn't quite straight? I'm pretty sure it's not the grinding wheel, as it was this way when brand new, and after truing the grinding wheel.
Can y'all take a quick look and let me know? Tx!

From what I can see on the video, it seems that only the rubber has some wobble. The metal wheel seems to be turning straight and true. So it shouldn't cause much trouble with your sharpening.
Have you tried sanding the rubber wheel with some 80/120 grit sandpaper as mentioned in the manual ? It is known to lessen this "problem".
Cheers,
Nick.
Looking at your video, I had the same impression as Nick. You should email Tormek support (support@tormek.se). Include your video with your email to support.
Unlike many companies, Tormek has excellent support, both in and out of warranty.
Keep us posted.

I agree with the first part... to me it just looks like the rubber wasn't attached properly and doesn't line up with the edge of the metal as it spins around. But I'm not sure sanding will fix this?
I don't think it's an issue, but I'd contact support, if for no other reason you have documentation should it become one.
Thanks for the replies. I think you're right about it being an issue with the rubber. I feel the wobble with the leather wheel, but not on the grinding stone. I'll contact support.
The leather wheel is attached to the metal rim of the wheel, not the rubber itself, so it should not wobble.
Are you not referring to the "bump" feeling you get when honing at the place where the ends of the leather strip meet ? If so, this is something that gets less noticeable - but still remains - overtime. It has no impact on the quality of the honing that I can perceive...
Cheers!

Yes, I think you're right. I set the USB close to the wheel and there's very little wobble at the leather surface.
