OK, I have to break down and try this.
What size nail, how much glue, etc... Tell me how you do it. (Please.)

Cheapest superglue you can buy. I like thin not gel. Coated nails so they don't rust. I like 20d and 16d and 12d . I have used finishing nails for small n opals. Put a drop of glue on the nail head. I stick the nails in a sheet of Styro foam to hold them level, I usually do 20 or so at a time. Used a candle to heat nail to remove the cab. Get it warm enough the glue gets real soft. Use my pocket knife or paring knife to pop glue off. I use a small butane torch now, no soot.

Excuse me for sounding dumb, but what is a coated nail? Is that like a concrete nail or a roofing nail?

Gorilla glue works good, you can brush it on. Wood golf tees for sticks, you can sand them down to a desired size and remove the pointed end. I still prefer dop wax even in the cold, just need to be a little more careful. I found that if I keep the stone warm, most times it stays on. Like I said most times, a few have got away and smashed or scratched getting stuck in the flat lap splash guard.

I use wood dowel cut to length or more recently aluminum round stock. Aluminum you can heat to soften the glue then I just pull off the cab. On wood sometimes putting into the freezer will allow them to be popped off, or you could gently pry off with a knife. More chances for damages that way.

Excuse me for sounding dumb, but what is a coated nail? Is that like a concrete nail or a roofing nail? Typically it's a vinyl coated framing nail that is commonly known as a sinker. They're used in framing, as the coating provides lubrication (don't worry, it's dry) and makes the nail(s) easier to drive. The coating also affords some corrosion resistance. Often they have a yellowish cast which makes them easy to identify. Can be found just about anywhere. Look here.Dave

Don't know. Perhaps the glue has its bond loosened at a heat that is lower than the melting temp of the vinyl. orrum? Dave

Tela, I only dop for the smallest cabs and for rounds.
Nail with wide, flat head. Not a screw which would hurt your hands. Flatten the pokey end of the nail, so you don't jab yourself. Don't use nail with a raised logo or letters. You can file them off to make flat.
Locktite gel. Gray squeeze bottle. Black ribs.
A little--- about 3 mm length max. Apply to back of preform. Place nail in center. Let dry a minute or two. I forget.
Check for stability. Go to it!!😀

what wrong with dop wax, easy to use, easy to cab off. and its cheap can use it over and over. the trick to keep the stone on the stick, you need to heat the stone. I have never had one come off

I use a hot plate to heat up the stones, to keep it on the stick heat, the rock has to be really hot, i cab in the cold and never had a problem.

Before I quit dopping the *best* combination of stick and glue (and I tried a LOT of combinations) was JB Weld epoxy and 7/16 wooden dowel. EZ peazy to do - mix up the glue apply a generous amount and let it dry overnight. For removing just a quick cut with a mini-hacksaw then smooth and finish the back.

Somewhere on here, Mel said he used Scotch Permanent Outdoor tape ( or similar name) because he wanted to cab in cold weather. Worked well. Will try to find the post.

</div> I get the wax and stone very hot. I use the electric dop pot AND a 60 watt bulb. I still have them come off. I guess I have been unlucky.

I'm with Orum (superglue on nails). If you reuse nails, heat the head of the nail to burn off the old superglue. Superglue does not like to stick to superglue. You can sand a bit or hit with an electric wire brush for reusing too. Cheap super glue (Walmart 4 pack) or dollarstore is better than the stickier stuff like Loctite. Just a bit of heat will let you pop off your stone, and then hit the back with a 220 or 280 grit wheel to get rid of glue residue. Wax is too temperature sensitive and takes prep time (superglue is fast but I do let it dry at least an hour before working on the stone - overnight would be safer). Any nail will do - they are cheap enough you can throw them away. Roofing nails have a nice big head for bigger cabs, use any size head that will fit on your stone. I use a wine cork on the pointed end of the nail, better handle and no point. Stone can not be oily and should be dry when glued. nuff said.

Dec 29, 2010 at 2:18pm shotgunner likes this Quote likePost Options Howdy folks, Been having problems keeping stones on the sticks in this cold weather lately so I was going through my box of dopping junk. Happened to stumble upon my old stick and heads for my old Tagit Industries cab crowner. I used to do all my dopping on this rig but finally quit as I was unable to find a tape that would hold the stones to the cabbing head. Having found the stick and a dozen spare heads, I went to Wal Mart to investigate what new tapes might be in the market and found the New Scotch Permanent outdoor mounting tape. The company claim is this tape is weatherproof and will pretty much stick anything to anything. Well, son of a gun, they're not telling a whopper! Took a 30 X 40 dop head, applied the double sided tape, peeled off the other side and stuck it to a large cleaned preform that had popped off with the wax. This was a big stone almost 2" by one inch. Tape worked like a dream and the stone was stuck so hard I couldn't pull it off by hand after crowning and I'm fairly strong. Had to pry it gently with a sharp knife and it peeled right off and peeled off the dop head easy too. Tape is only like $3.75 for five feet too. So now, I'm dopping all the stones this way, at least in cold weather. Problemo solved *L* Here's a pic of the tape and the dop stick from Tagit.....Mel Read more: forum.rocktumblinghobby.com/thread/42160/cold-weather-dopping-problems-solved#ixzz4te3z9EGr

Tela the coated nails costing is messed up on the nail shaft but it is still on the head of the nail. It's easy for me, put 20 or so nails into the styrofaom, put a dab of glue on them all at once, set the cab onto the nail head. I try to let them dry for a day.
