Took some advise posted here and slabbed up some various materials by glueing a 2x4 to the material with gorilla glue. This techinique works wonderfully well, but any advise on getting the last slab off the 2x4? ? The only thing I can think of is to cut it off with the slab saw. Will acetone or something else release it?

Soak it in water it will release in time 24-48 hours.
Never had one that didn't.

I had about 8 slabs gorilla glued on 2 by 4's laying outside my shop, just read this a little while ago, threw em in water and they are popping off already. Thanks for the info.

Great advice...They do sell deactive chemical that makes the glue lose its compounds,I use it with my fossils...........Most model stores carry it too.......

I normally use a 1X1 piece of maple with my gorilla glue and use a hammer and flat blade screwdriver to pop off the rock....water is probably easier on the slabs, though.

I had some plain yellow carpenter's glue that didn't want to release....so dear hubby suggested dropping it in one of his crock pots that he 'boils' his specimens in. Hot water did the trick! I was amazed at how well the carpenters glue stuck, even when the surfaces weren't super smooth and I didn't clamp it very tight. But this is my favorite way to slab my many end cuts.

A lot of interesting methods.....somewhat different that one that I had in mind. I figured that you would find a large ugly gorilla, have him grip both pieces and then whack him in the ball$......er......butt with a board. Bob

The slabs did finally release from the 2x4's but you had to soak them longer than I expected. Which brings me to my next question what type of gorilla glue do most people use when they do this? ? Do they use the standard glue or was I suppose to use the wood glue?
