Chosera stones peeling

Tue Aug 20, 2013 1:44 pm

I have a couple of Chosera stones that are peeling from their backing plates. What's the recommended repair method? These are fairly new stones, soaked and dried appropriately per the directions, so I'm not sure if peeling is typical this early.

*Normally* I'd say soak them in hot water for 5 minutes, as hot as the water will get coming from your tap, no need to boil them. That will loosen the adhesive, then carefully remove the stones from the blanks.

I said *normally* I'd say that! The Chosera stones seem to be the most fragile of the lot that can be found mounted on blanks for the EP. I have a couple of Chosera EP stones, my 10k has a slight hairline crack in it. I would not try unmounting either of mine to be honest with you. I have done several "remounts" of poorly mounted stones too. YMMV. Good luck!

Some of mine suffered the same fate. They are attached with what appears to be a spray adhesive. After cleaning all that off from the stone and plate with some naphtha, I used some slow set epoxy (G Flex) to glue them back together. Some spring clamps hold everything in place for a day or so until good and dry. No issues since, with some a couple of years ago.

Hope this helps.

Thanks, you both.
I'll give the hot water and epoxy a try. I have some 3M adhesive remover, but am weary of using that on the stones. Thankfully, the issue's specific to the #400 and #1000 stones. The finer grits appear to be well bonded.

My 10,000 grit is slightly off center, but has never came loose.
