I recall seeing at least one thread, maybe more, where there was a discussion about how to get that very last slab off the end of the rock, by glueing it to a piece of wood. But I can't remember the details, and I cannot seem to find the thread. And the "search" engine won't search on 3 letter words like "cut", "saw", "end" "2X4", etc.
Any help please? What kind of glue, how do you unglue, etc.
Thanks, folks!
Tom

Tom, Exactly what Keith said. Gorilla Glue on a 2x4 and let it dry overnight. The stuff expands like crazy so you don't need to use much. Works awesome. When your ready to pry the end off...dip it in cold water and a flat screwdriver behind it usually pops it off. You can slice right to the wood too. Steve

Keith, thanks!
So if you cut into the glue, it won't foul the blade? Hmm. I have some wood glue, some Goop, some 330 Epoxy, and some cyanoacrylate, but as it happens, no gorilla glue right now. I'll have to go to Home Depot yet again. Oh, well, there are worse places to go, for sure! LOL!
Thanks for the tip.
Tom
PS - thanks, Steve, also!

The thing you need to watch for is when you think you need a little more glue you have already put on too much Keith

I've been using a home made slab grabber. Last time I used it, I cut through a screw head. Good thing it was aluminum!
I might switch to the Gorilla Glue method. Seems easier, provided I have the patience to wait for the glue to dry.
Thanks for posting the question!

I've heard that water glass can also be used to glue rocks to a piece of 2x4 and then slabbed. then to get the last slab off of the board, just soak overnight in water to dissolve the water glass.

Well, I got some Gorilla glue and tried a couple of rocks with it. I had one end-cut done, and I glued that flat surface to the wood, left it overnight, then cut it up. Works like a champ! Thanks for the info, folks!

Gorilla glue works great but try not to get it on your skin,it takes a few days for it to wear off.

Gorilla glue works for me. As we call it in the wood shop (Gorilla Snot) Works great and only takes a little to hold a lot...

I use crazy glue and a scape piece of agate That I cut into a block. No waiting.Last slab stays on the block. And always a square cut. If you want to remove it just soak it in acetone.

I know the consensus here is to use Gorilla glue, but I use interior grade wood glue. I have never had one come loose and you need only throw the last slab that is connected to the 2x4 in a bucket of water and it will come loose itself in a day or two and you can wipe the now soluble glue off of the last slab..
I measure the rock good enough that I end up with a perfect size slab at the end connected to the wood. You can speed up the water taking off the slab by cutting the last slab off of the wood about an 1/8 inch from the slab on a table saw before you throw it in the water.
I threw one in the water last night and just pulled it off the wood off the slab this morning.
Hope this helps, Hope

I tried the wood glue a few times but I found that if I was cutting a lot and the oil was hotter the the glue began to turn loose. I never have had that problem with gorilla glue. Keith

I did use the gorilla glue, and it stuck really well. I wasn't able to force myself to crank the vise in close enough to cut the glue, so the last "slab" that remained on the wood was maybe 1/32" thick. I soaked it for 36 hours, then gave up and used a screwdriver to break it off the wood, one little broken chunk at a time.
I did use a lot less glue on the next 2 ;D - we'll see how it turns out.
