I have one that was a 100 grit when new...that is very worn...down maybe to 350? Does anybody have a used course one that you want to sell, please?

Do you mean SiC or diamond. If Sic, just dress it. Do you want 1" 1.5" or 2" width?
The nickle braised ones form rocklady or jadecarver are pretty cheap in 1.5" widths. I use an 80g but it is very agressive.

The ones from Jade carver are pretty low cost and for me last long enough for the great price. I just got a new one the other day. $65.00 for a new 1 1/2" wide diamond wheel

yeah, and 1" is even cheaper - about $45. rocklady is about the same price as jadecarver
the only time you are going to find one of these used is if it is sold with equipment. or if somebody took off 100g in favor of 80g. but you hardly ever see these used. it will also be unclear how much life is left. shipping approaches about 1/5 the cost of new.

Reverse the old wheel and lightly dress it. You'll find it's still 100 grit, just you've worn them down to where the braising is now in the way.

If you are still looking for these, I spotted these on ebay today. Can't vouch for the seller personally as of yet (has 100% feedback rating on 859 transactions, FWIW) / I have no stake in their transactions, etc. etc. tinyurl.com/m852nr9180 grit, 6" x 1", claimed to be in NOS condition - manufactured by Chrystalite tinyurl.com/m9cou9mIf the links don't work, look for the seller ID of mr.88 360 grit, 6" x 1", claimed to be in NOS condition- manufactured by Chrystalite Best regards, Jack

Thanks. yeah, most folks don't realize that diamond wheels are supposed to be reversed every 40 hours (? not sure) for longer life. Not sure about the 40 hours, I'd have to go dig out my manuf specs to get exact time. I do remember it seemed to be too soon, too often, so we reverse ours about once a month. Exception would be the ones that have an arrow indicating rotation, those are unidirectional I guess? Oh little tidbit for the rest of the diamond crowd... I recently bought $1200 worth of diamond wheels that were made by Reentel because the price was the lowest for the 11 wheels we needed. (total conversion from SIC to Diamond). Had one go bad within a month - the belt started separating, so we phoned and they replaced it no problems. However, when flipping thru their website, I read with a little disappointment that their wheels are DESIGNED for 3 to 4 months use only... Rats. The bright side is I now refurb our old diamond wheels myself when they wear out, and so far (knock on wood) the wheels are working better than they did when new. We'll see just how long all their wheels last. Course, where they used 5 carats of diamond, I use 10. Makes a huge difference. Oh... I'm also in the middle of converting an old thumper (split) wheel into a 50 carat, 100/120 grit bruiser! Can't wait to use this 3 inch wide wheel when we're all used to the skinny 1.5 inchers!

phile, I generally figures resin bonded diamonds were good for sanding wheels, but that they would be less good for lower grit grinding wheels For example 100g nickle braised diamond wheel lasts me a while. 100g vertical belt sander belts don't last too long.
For removing scratches > 100g, I think what you are making is great. For example to smooth something more of less shaped on a 60g wheel. But for removing lots of material to get the basic shape (what I call grinding), I think the resin bonded diamonds are less useful/hardy.
do you have different experience?
