Couldn’t you drill into the wheel itself to get it into the ballpark before you use the balancing ring?

There is a large segment of users who do that. Even Suburban Tool does it. But I don't feel comfy about it.

@Tom Kitta climbs hymalayan mountains, I can't climb a step ladder. Suburban feels safe drilling out grinding wheels, but I keep picturing it disintegrating on me. I guess we are all different. Prolly a good thing. There is also an interesting view of this practice on Precision Kinetics Website.

Edit - should be Kinetic Precision

I think the best advice I got yet is from @thestelster ..... He says "Pitch it!"

I might try shimming it first.

After writing a book about my knives, I went out to the shop to play with this bad wheel a bit more.

I shimmed it with a piece of 5 thou feeler gauge left over from another job. I put the shim on the current light side to push the wheel toward the light direction. I could prolly fit a few more thou in there, but the spring action of the shim pushed it as far as it would go anyway. Then I snugged it up on the arbour and put it on my makeshift balancer.

It was a wee bit better than it was before, but not by much. It still takes WAAAAY too much weight to balance.

So ya, it's basically a junk wheel. I'll prolly play with epoxy just for poops N giggles. But not today.

Any other thoughts about things I might be doing wrong?

It turns out that a major flaw in this arbour is that the right side shaft needs to be at least a half inch longer. Some wheel arbours are fatter than others and the arbour barely reaches the balance rod.

I am going to make a longer one shortly.

Here is the Sopko arbour and dimensions for reference.

That's much better.

Ground Rods are now levelled on small V-blocks with nothing hanging over, nothing close to touching, and a half inch extra for a wider stone. 7.14 degree (1 in 8) taper is a difficult number to hit....... I must have nailed it by chance last time... LOL!
