A lot of my rough already has cut faces that I want to follow. So far, for larger rough, I’ve been trying to veeery carefully align the cut to the blade while clamping, then make the first cut a bit thicker than I want just in case. Smaller pieces have been getting set aside for gluing, eventually. I’ve been scared to glue up this guy because I am worried about gumming up or damaging the vugs too much. Am I just being paranoid? Is there something other than board glue that I should do for vuggy rocks? How to remove any leftover glue? I have various solvents around but no clue what’s safe for rocks. The largest face is the one I want slabs of the most. Was planning to use titebond original (red, interior) to make it easier to remove later, but also have titebond 2 (blue, indoor/outdoor) if that’s a better option. Saw is running on mineral oil. and last question, since I am terrified to experiment with it myself… any clue what my weight or overhang limit on the board gluing is? I primarily have untreated 2x4 scraps and tons of salvaged pressure treated woods, but willing to buy wood or attack my log pile (oaks and maples 80+ yr old) if the wood grain is the deciding factor.

No idea if this will work - but for dopping with wax I fill a druzy or vog with sugar, and then dop normally. The sugar just washes out.
I've used titebond 2 for gluing /sawing, and found soaking in hot water worked best.

Since the vugs are only in one small area and on the edge, i would just put a small piece of masking or duct tape over it. There is plenty of area left to get a secure glueing to a board.
For the glue, either one will work. The red titebond might be slightly easier to release from the board. When you are done slabbing just throw the wood block with the remaining rock into a bucket of water. It can take anywhere from a day or two or up to a few weeks for the glue to dissolve. Usually therenis no glue left on the rock, but if there is I either scrape it off with a razor blade, or use a scouring pad (eg: scotch brite)

*sighs* seems like I’ve been overthinking this again! Tiny pieces of tape will probably be best for me, since I don’t especially like the idea whatever I fill it with getting mixed into my oil when it’s cut (no clue how deep vugs go). Should probably go for titebond II, as well, since I am insanely paranoid about rocks coming off! The face of this rock is glassy smooth as well so will scuff it up a touch to ensure a better bond.
Anyone ever have a rock detach from the board while cutting?

I am also thinking I will order one of these whenever the website to order from is up. I don’t have a drill press so would be a huge pain to make myself. something like this would make it tons easier to get smaller rocks slabbed! Could do something similar with wood and screws if I didn’t reuse the holes a lot, but will just stick with glue until I can buy this.

Hmmm . . . wonder where they got that idea?
