I have one of these Leonard grinder-lap machines and it is awesome.

Uses 5-inch magnet based diamond wheels, runs at about 350 rpm and has an eccentric to make it wobble a little.

Awesome for sharpening and polishing lathe tools and carbide inserts.??

Thank you for the replies. I will be researching the nickel plating process now that I know it is done commercially. No one makes replacement grinding plates for this machine. I have searched all of the obvious places. Not sure when they quit making it, but it is perfectly designed to grind lathe/shaper cutting tools. I will try to post a picture tomorrow.

This is a tangential topic at best. The question is does anyone know of a way to bond diamond grit to a steel plate? I am thinking about experimenting with general purpose epoxy. However they bond brake linings could work, but I do not know how. Regular epoxy seems like it would fail as the plate heated, but the brake lining adhesive should be more than adequate.

Background: I have a 1950's era grinding machine that uses steel discs with bonded diamond grit on the flat side of the disc. It would be perfect for HSS or carbide sharpening given its adjustable angle work table. The problem is that the abrasive plates are not available any more. Self-adhering sanding discs are an option, but not preferable.
