I have one of those Polaris slab grabbers and have had mixed results. Read past post on this forum about gluing the rock to a 2"x4". Works great! Used a old bottle of Elmer's yellow wood glue I had laying around. I let the glue dry for 2 days. I first thought the rock would come loose since everything was getting wet but it held. I was able to get a few more slabs out of each rock and then I threw the wood block into a bucket of water for a couple hours. The glue turns into a slimy goo. The glued piece of rock came off by just prying with a screw driver. Comes off so easy, the screw driver tip slips and jams into the palm of your hand. Ouch! Don't do that. Set the wood block on the floor or on your work bench. LarryS

I find the ole Elmers holds great but even after soaking in water for 2 days the last 1/8 slab stuck to the wood would rather break than let go when I try to pry it off.

Great idea!
someone else had a thread about gluing end pieces to corrugated cardboard with contact cement, then gluing the other side of the cardboard to another stone.
So many creative people here. Thanks for the knowledge.

I do this also...works well, better than Gorilla Glue!

I use gorilla glue but don't try to remove the last slice, I just cut it off. Either way its a great way to get the most out of nicer rough.

I always want that last piece! If you want to get that last little piece off, consider weighing down the block and slab in one of those minicrock pots (or a bunch of blocks in a standard crockpot). Heat up the water and let them sit...comes off great! And we got a bunch of cheap crockpots at Aldis when they went on sale, but yard sales also have them. I have more crockpots in my garage than in my kitchen! (husband uses them to soak rocks and minerals in assorted chemicals...super iron out, etc) Sue
