The diamond plate sharpening stones are bonded by spreading the diamond grit on a piece of steel and nickel plating it to hold the diamonds bonded there.

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.

I would think about the epoxy used for industrial floor coatings

Looks like I'm a little late getting to the party but after years of searching the internet, I finally found an Sb1002 for sale and am in the process of cleaning and refinishing.
?
Through the years of searching, I found one for sale on the average of once a year.? The first couple I let slip through my fingers and have regretted it since but at last the fun begins.

It’s a glorified crowbar test. Put an indicator on the
top of the spindle. Stick a piece of heavy bar stock in the
spindle or chuck and lift upwards. Someone else can chime in
with the allowable deflection but it’s something around 1
mil.?

Animal, can you be more specific about the ‘rod thru the spindle test’? I’m not sure what that is or how to do it - thanks.

I have a 1947 SB "Heavy 10". Whenever I exert a little too much pressure
when using a parting tool, I can hear 'banging or clattering' in the headstock.
Is this an indication of worn out main bearings?

Thanks for any help.

Check the locking pin in the headstock bull gear. I would bet its worn under size.?

Re: Speaking of lathe belts
I also have been thinking about the? issue of flat belts. If you live rural ask a farmer if they have discarded belts from a round baler.?? Asked a neighbor and he had several, 6 inches wide and 18 feet long. He also had the splicing tools.? It took some effort to cut them to size but I replaced the belts on 3 machines for zero dollars.
??? ??? A belt place can slice to what ever width ya want . One
of those tape measures that sewing folks use can be real handy for
measuring what size belt ya need , Real handy for measuring all
sort of round things .
