so if you where ever wondering, hot glue does not work when attaching stone to wood, I tried it, it just doesn't hold, I used some white glue/elmer's on a cut surface and that seems to hold up nicely. I've heard of people using 2 part epoxy's and super glues but no idea how easy those would be to remove.

I think the key to any glue is making sure the rock is clean of oil prior to attempting to glue up.

You can remove super glue with acetone. I use a super glue like product for my dop sticks as opposed to wax. Stu

the white glue works, but takes a while to dry, think I'll give the super glue a try, thanks guys.

The best bond I've been able to achieve between wood and stone was with the polyurethane based glues (Gorilla glue is a good brand). The one down side to this one is that it does expand slightly as it sets, so allow for that and have some good clamps. I've attached petrified wood slabs to wooden table bases to create permanently bonded furniture. I use a lot of CA (super glue) and I wouldn't trust the bond to be permanent or to deal well with the different shrinkage rates between the wood and the stone due to temp and moisture/humidity variations.

I use 5 min epoxy and golf tee's it works great and when you finish just run the cab under hot water in the sink and use a knife blade it will come right off. I have never had a problem with it coming loose as long as you clean the cab well. Keith

I buy it at Walmart they sell a 1 min and a 5 min. I have used the 1 min to do a quick 1 or 2 cabs but it sets up fast. The 5 min I can dop 15 or so before it starts to set up.

I use the 5 min epoxy from harbor freight on aluminum dops that I cut at work with a lathe. To remofe I heat the aluminum dop with a torch or butane lighter and the stone pops right off, them a razor blade scraper takes it right off the stone.

To attach a cut rock to a block of wood clean the rock with lacquer thinner a couple times doesn't hurt. I also mix regular white glue with yellow carpenters wood glue. 60% white and 40% yellow mix it will be very thick. put a good layer on the block and let it dry, then add some more glue to the rock and place it on the already glued block, make sure it oozes out all sides. LET DRY AT LEAST 2 FULL DAYS. After that you can mount the block in the saw and cut every last bit of the rock. The last slab will come loose if you soak it in water for a couple of days. It is important to have the first layer of glue on the block otherwise the glue won't come loose and you will have to cut the wood to remove the slab. I use 2" X 2" oak blocks 5 1/2" long. fits perfectly in my 10" saw.
