The strategy of attaching a flat surface to a wooden stub to maximize vice grip and range of the rock available to the blade is a great one. Thank you for this tip. However, how much attention due I have to give to the fact that my wooden 2x2s are now oily. Will Gorilla glue stick to them a second time? Do I have to use a new one or at least saw off a clean surface? Or can I merely soak them in cat litter like I treat the rocks (but thats going to add dust - a no no). So far I've had a couple of rocks pop off of the stubs (they were probably not given enough Gorilla Glue). I'm cleaning the surface of the rock with a solvent to remove as much oil residue as possible. I'm using a rough sawn 2x2 but could get blocks of hardwood sanded to a tighter finish if thats needed. Any guidance from a rock master would be appreciated. Tom

I use the wood glue method and I after the first use I soak the 2x4 with rock attached for about 5-6 days in a solution of water and dawn dishsoap. After the rock falls off I scrub the 2x4 with the same water and soap then let it dry out and cut about 1/4 inch off to start fresh again.

I do something similar to Chuck. I use my radial arm saw to cut the rock off the 2X4 (after rinsing off the oil), then square up the wood, if necessary, and reuse. I throw the sliced off rock into my de-greaser bucket (dawn and water) and pry off the glue/wood later.
Gorilla glue ain't 'fraid of no oil...

The use of 2X2's may be your problem with bond failure. I have to use 2X2 with my 10" saw due to the small vice and had loss of stickum' occasionally.
With my bigger saws, I use plain ole pine 2X4's....giving more adhesion surface and seldom have a rock break loose.

I use end cuts from building projects and the large boards from broken pallets at work. I cut them down to between 2-3 1/2 inches depending on the saw they go into and toss them when I'm done. They make a good fire starter for the backyard debris pile.

and clamping devices are a nice alternative to gluing onto wood.

I used to use gorilla glue and 2x4' s but have since gone to a slab grabber. Leftover scrap lumber is easily obtained for free, I never reused the lumber.

I also use 2x4 stubs, but husband has been applying them with bondo (something learned from a member of our rock club). However, that's not as inexpensive as glue, and quite a bit harder to remove than a wtaer based glue. The wood blocks can be reused, but only after you've gotten the saw oil off of them. Or just buy more, 2x4s don't cost too much.
Another club member just told us about using sodium silicate (wet glass) as a glue. It dissolves readily in water, so removal should be a cinch. I need to get more information, and give that a try. Jean

I guess I need to buy a 2x4 eight footer and saw away. I guess I was looking for that answer. Thanks.

I use regular elmers wood glue, holds as well as gorilla and costs a lot less. Of course that's only when cutting with oil.
