Jeff have you found a surface grinder ?, are you setting up shop somewhere?
Yes, see PM.
Thanks again BOB!

"The first wheel I bought for my SG was one that would serve as a general purpose wheel and also be a good selection for dusting my magnetic chuck. I decided on a 32A46-HVBE from Norton. "
And your go-to, medium and fine grinding wheels of choice? Or, can you use this wheel for multiple applications?
I assume 7" x 1/2" on all?
Thank you!
I have found that the cheapest no name import wheels are not worth a damn. Out of balance, wobble, tend to burn the metal, just awful. Sometimes used wheels can also be out of balance from coolant settling down to one side and then drying there. If you are using coolant, let the spindle run for a few minutes after stopping the coolant to let it get thrown out of the wheel.
Coarse wheels do not get filled up with swarf so easily. A really fine wheel fills up quickly, and then the swarf ruins the finish. With a coarse wheel and looking for a good surface finish, slow down the traverse and cross feed table feeds and speeds somewhat so the coarse grit has a chance to find all of the surface. The finish can be very good.Wow, 36 grit. You would think that would leave a rough surface.
I recently made 2 wall mounting boards for my grinding wheels out of plywood I had laying around and hung them behind my surface grinder. I put hardwood dowels covered with clear shrink tubing into holes drilled 7 degrees upward from horizontal to match the adapter taper and to help keep them from falling off. I put screws into the dowels from the back side of the boards to expand the dowels tightly into the plywood. The racks are hung with some galvanized sheet steel I had laying around. Zero money was spent on the project. Designed to use what I had on hand.Not to hijack the thread I think it’s relevant. How does one store their wheels? Mounted and unmounted?
Lay flat ,upright, peg board?
