Anybody ever try gorilla glue for dopping? Would a screw head hold? How would you remove the dop, if it works? My black dop wax doesn't hold so well.

I have never used Gorilla Glue for anything, but I have good luck with super glue for dopping. Once I'm done with the cab, I put it in the freezer for a few minutes, and then pop the stick right off the stone. Occasionally there's a little residue left over, which I scrape off with a knife. I then work the back flat on the lap (by hand with no stick) up to at least 600.
I use 1/4" dowels for dop sticks, but have used smaller diameters depending on the cab size.

I am a newbie and have only used dop wax but I have heard of many people who use Super Glue and then nail polish remover (acetone) to break the bond. Gorilla glue may work but even the fast cure type takes 30-60 minutes to cure.

Thanks, didn't know there was such a long cure time for gorilla glue. I guess it won't be a viable option. Just need to know how much superglue to get and find a way to keep it from clogging the tip. I end up throwing more super glue tubes away that I ever use because the tip always clogs and running out for a new tube of superglue everytime I do a cab ain't happening. ;D

try the dollar store, always super glue in the larger sizes up to 1oz and the larger bottles tend to not clog

I have had good luck with the recent package I got from wal-mart. I believe it was 99 cents for 4 tubes and I found it in the automotive section. I have had trouble with the lids gluing on too, but have found if you squeeze very lightly to just get the glue flowing, it will drain back into the tube when you stand it up. Then I store it upright also. Good luck, Nate

I tried Gorilla Glue for dopping and it didn't work, kept popping off even after letting it set overnight. Super glue works much better. Gorilla glue does work really well to glue felt pads onto a polish disk. Holds well yet can be ripped of when you need to replace the pad.

I have had extremely good results with dop wax - black, brown, and green. The trick that I finally figured out is that the stone must be clean and dry, and both the stone and the stick need to be hot. I set the stone on the dop pot edge and let it sit until it sizzles when I touch a wet finger to it. Then I let that moisture evaporate as well. I put the dop stick into the wax and let it set for a few minutes before dopping the stone. So far, the only ones that have come off, were because I didn't get the stone hot enough, or I got moisture between the wax and the stone.
So, I dop. Haven't tried any other method except "going commando", and I don't do that any more - I only have an Expando wheel, and that puppy hurts when you jam a finger into it!
Just MHO,
Tom

I always seem to end up grinding chunks of fingers and thumbs when I try to go commando. Ends up bleeding all over the rock and if the rock has a hairline fracture in it, it turns red and doesn't come out.
Does anybody use super glue on the front of the cab or do most of you just finish the back of the cab flat?

Here is a tip for using super glue.
Make sure the applicator tip never contacts the work at all. Crazy glue cures on contact and any contact made at the tip will start a curing process that will clog the tip every time.

Also with super glue you don't need a remover. Stick your cab in the freezer for 3 minutes or so then it'll pop off. I use it all the time, like suggested above, I buy mine at the dollar store.

Here are two sources to buy super glue very cheaply, and it is the same quality as any other super glue. If you are buying it one or two bottles at at time, here is the best place: www.e-zbond.com/The second source is cheaper but only because you have a rather large minimum order. Same product, though: www.e-zbond.com/Remember to buy some activator, though. Spritz some on the glue after you have placed the cab on the top, or spray the cab and then place it onto the glue on the end of the dop. Either way, it hardens the glue IMMEDIATELY.. no waiting. Also, buy some Debonder which will dissolve super glue when you glue your fingers together. You will wish you had it if you need it! Acetone will work, too, but Debonder is faster an easier to use.

By the way, E-Z Bond super glue comes in three different thicknesses. I suggest the thicker type for dopping.

You can use baking soda to harden super glue fast too. Also good for filling cracks when mixed with rock dust.

Does anybody use super glue on the front of the cab or do most of you just finish the back of the cab flat? I have super glued the stick on the front of the finished cab to finish the back, but had it damage the finish once. After that I decided to finish the back by hand. Nate

I always take the back of my cabs to 600 grit before starting on the front. After the front is finished, it just takes a couple minutes to bring up a reasonable shine on the back. I'm old school. I only use green dop wax.

I am doing a newer method using Loctite red cap and Loctite blue cap Gel for faceting, especially opal. A touch of the red gets the stone in place, then a bead of blue around the dop and stone keep it on longer, even when getting a little wet. I let it cure at least a day (I always have at least 5 stones on dops, so it is not a big deal waiting a day). Acetone removes it. And with faceting, I just transfer to blue and use a paring knive to take off the first dop.
