My 95% solution is the freezer. 75% off the time they come off with little pressure or even fall off the stick when in the freezer. Plan B is to take the cab out of the freezer, put a razor blade between the dop and the cab and whack the razor blade with a utility knife. I have had a very low failure rate doing that. If I am concerned about a particular cab leaving a divot or breaking, I would soak in acetone. Stardiamond is absolutely right about the freezer. Haven't lost one stone to that method.
Thanks, both of you. I've always used superglue with opals on brass rod (and heating with a butane torch to remove), but in the past few months for larger cabs I switched to superglue on wooden dops . I had been using acetone for removal, but I'm pleased to know that the freezer should do the job. I'm going to start doing that for non-opal cabs. Thanks.

My dops have plastic chair glide nailed to them. When the glue gets lumpy, I flatten against the 80 and 220 hard.

Interesting! Glides certainly would make the glue more effective and prevent glue absorption by the the wood.

Whatever method you use, don't get in hurry! freezer, leave it at least over night. time is your friend with any method, let the heat or cold or acetone do it job. DON"T rush it.

I made these some time ago adn shortened some of the dowels so they wouldn't get in the way of the wheels. I made the one on the top because it was slip on instead of nail on but I don't use it. small, medium, large and thick dowel large.  |

I had 8 cabs dopped with superglue including the one that fractured. 7 came off the dop either by themselves or minimal force. The one that didn't was The Morgan from Paul. Normally, I would stick a razor blade between the dop and the cab and give it a good whack. I would feel really stupid if it broke. I put it in the freezer overnight and it wouldn't budge. Since it was still on the dop I decided to re-polish it based on Paul's recommendation. I put it back in the freezer and after a few hours it surrendered and the glue scraped off the back easily.

@hefty.
Re: separating epoxied stones, doublets, etc
My husband (who has worked extensively with epoxy) suggests heat would be the only sure way to separate them.
You need to put the stone on a hot plate, or such and heat it to between 150 -200 degrees.
You should be able to slide them apart.
Warning- wear insulated gloves, welders gloves, etc

Heat or freeze works. Also the gel type hardened with baking soda breaks off easier.

At one time, I was using the Scotch double sided tape between the dop and the cab with superglue on both sides
of the tape on Montana moss agates because the dop was really stuck on.
I used the freeze and pop method. I now insert a xacto chisel blade between the dop and cab with the flat side against the cab. I gently tap, the end of the blade holder with a utility knife and move the blade around the dop until I find the right spot. I don't bother with freezing.

I used different nail on chair glides and the ones with black were part of the glide.
