That's mine. Great design. I saw the link for the replacement plates
too! $109 a plate is not awesome, but probably cheaper than making
one. Do they last? Which grits do you use? This is a great example
of being careful of how much you pay at an auction because the part
you need to get it to work could cost you a lot.

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.??
??? What kind of machine is it ?
??? thanks
??? animal

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.
