So, after considerable thought and reading, I was ready to pull the trigger on a CBN wheel (or 2). Not so quick! It turns out, I wanted a 1.5 inch wide wheel without radius corners. I would prefer a 5/8" bore rather than a bushing. And, I would like 180 grit to start.

I've apparently painted myself into a corner as this combination is not that popular and when I did find it, it was out of stock!

I guess I will have to wait a bit.
