Could these engraving tool sharpening wheels be adapted to your machine? Pricey, but may save you some trouble. I do have a few if you need dimensions.

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.

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

uses steel discs with bonded diamond grit on the flat

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

Re: Automotive flat belts for lathes
That is probably the best option if you can, but is not possible
for many of the under-drive lathes where the belt passes through
holes in the casting.

(How much overlap should be good?)
The Duralast info states the material is
rubber.
Come to think of it... any reason Clipper
links wouldn't work? Would they rip thru the material when
under tension?

I used one for years on my 16” SBL.
Cut on a taper. Use a
belt sander to make opposing tapers on the belt
Glue, overlap the taper
belt edges, clamp and let sit overnight.
I forget what glue I
used, might have Been Permatex??

You can make your own using those lapidary disc's. Cut their diameter to size and mount them on a steel disk using neodymium magnets.

Re: Automotive flat belts for lathes
Thanks for the replys. I guess my main question would be the type of adhesive to use.??
Also, I'm not sure if i have the ability to cut an even taper on both ends, so I thought a stepped lap joint would work (??)??
(How much overlap should be good?)
The Duralast info states the material is rubber.
Come to think of it... any reason Clipper links wouldn't work? Would they rip thru the material when under tension?
