oval water stone

I think you should be able to get away with just using the rotary wheel dresser. Just be careful not to let the stone get up to any speed until you've completed dressing it as the vibration could destroy it ( And You)

. . . .Thanks... I figure I will have about 60 rpm, and running in a water bath, when I try this.

I don't quite understand why you can't do something to center it. Could you not figure out where the center ought to be, and enlarge the hole so that it is centered. Then make a bushing to reduce the hole to the diameter you need.

I think Harbor Freight sell a diamond hole saw that might work if you have a drill press.

Thanks, that's something I had not considered, but surely will now.

I would consider mounting it, turning at a couple hundred RPM, and dressing it with a single-point diamond dresser. The diamond should easily take off the high spot without banging it like a multi-disk dresser would do. Diamond dressers are cheap (I think I paid less than $5 for mine).

Seems to me - it would be somewhat easy to use a hard wax or the like, put the stone on a stick or metal rod using the wax as a side attaching material - around the 'stick' and flowing down across a small area on the stone.

It can be removed after turning - with a little heat and maybe some turpentine to get the rest.

Keep it cool while cutting - and all would work out well.
