 Post subject: Removing stone bases...

Morning y'all,
The majority of my stones have a plastic or wooden base. I would like to remove them now as they are becoming more of a nuisance with each use. I haven't found any solid solutions searching the web, but one thread I read suggested putting them in a cold oven, bringing it up to 160D, then pulling them out. Has anyone ever tried this, or have another solution?

Thanks,
Charlemagne

I've heated the plastic base with a hair dryer and it came loose from the stone fairly easily. The issue is really removing the glue, or whatever it is, from the stone. I've never had a problem with the wood based stones and have never attempted to remove one. I can be pretty cavalier about things like this . I expect most would say leave the bases on so the stone isn't damaged in the attempt to remove them. I can't imagine wanting to heat the stone itself.

If you have any Naniwa stones with the plastic base just leave'em, parting the Red Sea is easier.

Can't say anything about stones but we use heat from a soldering station or heat gun and acetone to remove all kinds of epoxy, glues etc.

I cut and grind the bases off, but I haven't had to do this in years since I rarely buy a stone with a base. Anything else and you risk cracking the stone and sometimes the cracking won't show up for a while. You should be quite skilled and careful doing this if you like all 10 of your fingers :)

Thanks guys, definitely gonna give it a go on one soon. I don't have equipment to grind off the bases, so I think I'm gonna let one stew in warm water for a bit, then attempt to pry it off. Over-heating the stone is a concern, but I gotta give it a shot. Good or bad, I'll update the result.

"Anything else and you risk cracking the stone and sometimes the cracking won't show up for a while.":

Prying AND heat are two ways to increase the likelihood of failure. Just saying. BTW WHY are you removing the bases? There may be other alternatives here.

Hey Ken,
Thanks for your concern, and I did risk some serious issues taking them off, but it went well. To answer your question, I kept the stones in water, which resulted in some warping and deformity, plus I'm not really loving the look anymore. I went ahead with removing it and it turned out great except for all the ugly epoxy, which isn't a real problem for me. No visible hairline cracks to be seen, just a few micro-chips that a good chamfering will take care of.

I placed the stones in a pan with water just 1-2mm up the stone, brought it to simmer and let it sit off heat for about 20 minutes or so. Then I slid a mini spatula under the stone width-wise and shimmied it along the entire underside until it was off. The damage seen on the Arashiyama 6K is an old one from a drop a while ago.

Looks pretty good. Now just get some real coarse sandpaper 36 or 80 grit or so and tack it down and grind the glue residue off of the stone so you can use both sides of the stone. Glad it worked out.
