The guy that I purchased my saw from uses "Liquid Nails" to glue the faced end of the rock to a wood block of 2x4 and them lets it set up for 3 days. He said that he's never had one come off before. Some of the rocks that he glues to the block are fairly good sized. He slabs up to about 1/8th inch from the wood block.

Sorry if my questions might be a little simple. I see there is 3 different sizes, do i need all 3, or is there a "do all". This is my first outing with a slab saw.

The LRG-1 listed on the MLS catalog that geodes4u mentioned is the one I would pick. I have 2 old Bobs rock shop slab grabbers just like it, and they work for most any rock.

How is the remainder of the rough removed from the 2x4? As in, how do you get the liquid nails off?

another trick i used for cuttin the basidian i had was to do an end cut rough up the end a little with sandstone or wheel dimple the end of a 2x4 and use wood glue when dont cuttin drop in a bucket of water the glue will loosen and the slab will fall off it worked great on other tip let the glue dry for a few days then try to pull twist the rock off

An old timer showed me how to hold geodes using 3 sided pine 1 x 4 rectangles. Clamp the wood with the geode in the open side. I slab rocks down to the vise then turn the rock around and using the pine geode holder cut the heel as far as I can. I usually end up with a thick piece from 3/4" to 1.5". I face polish that and put on the table as a polished specimen piece. If the rock has no orientation you can also take the thick chunk and end cut cab sized strips. I cut right through the wood sometimes so they get a little shorter each time. I use scraps from other projects so no real cost.

Yes, rockoonz suggestion is very good. Just take your time and make sure that you have a really good bite on the piece that you are cutting.

I can be a little dense sometimes. For the life of me I can't figure out what this means: "3 sided pine 1 x 4 rectangles". :help: Later, jeri

Don't feel bad Jeri, I had a Construction firm and did construction all my life and I can't figure it out either. ;D ;D ;D Ken P.S. I have the small and large slab grabbers (3" and 5") and love them and use them all the time.

Shannon Usually by the time he's done slabbing, there's not enough rock left on the wood block to be worth messing with, he just throws then in the wood pile. Once in a while with the pricey stuff, he said that you can soak the block in water for a day or two and it will come right off.

I've had good luck with the water based craft glue I think called "Sticky Tack". If comes in a brown plastic bottle sold at Hobby Lobby and Michaels. What I do is similar to what Randy describes in gluing the cut side of a rock to the end grain of a 2x4 or 2x2 block then cut slabs and on the last slab cut through the wood as close to the rock as possible leaving a small slice of wood glue to the last slab.
Then when I have a bucket of slabs I file the bucket with water and hand dishwashing soap and leave them soak for 2-3 days. Then I run water in the bucket so the oil flows off the top and usually the wood floats right off and there may be a little glue left of the slab that you just need to rub a little under running water and it washes away.
