Superglue or double sided carpet tape.

I wonder if threadlock compound would give enough grip on flat surfaces. I use it to hold 1/8" cutter shanks in silver steel shafts in my Roland engraver (reamed hole, so close fit), and it lets go with mild heating. The extra area holding, say, a washer should give it a fair bit of grip as long as there is a close fit.

Using double sided tape is very effective, but gives an unknown and uncontrollable distance between the workpiece and its holder, so is not ideal for precision work.

Hot melt glue ?

The method mentioned by JS will hold quite a load, when I was wood turning I used that method when making large bowls, mostly 9" diameter by 4" deep Mahogany, the base of the bowls were usually about 4" diameter. Instead of soaking it in water, a chisel at the joint, a sharp whack with a mallet splits the paper, then a damp cloth takes of the remaining paper and glue. I'm not sure of the weight of the wood, but the blank I started with was a square bit with the corners cut off, and you don't need to go gently when you get working on it.

True! I tried to make my gluing area the right size for the finished base, then I didn't get the tool in the joint area. I usually could get two or three small bowls out of the large one(waste no want not), to make these you must dig deep into the face of the bowl blank, then hit it hard with a hammer, and the waste bit breaks out, and you can finish that later, but the glue paper glue still holds(I think one came unstuck).

Old fashioned Nitromors paint stripper shifted loctite, but I've been told they have reformulated it so not sure whether the new stuff does. The active ingredient was dichloro methane, but it is wicked stuff, very volatile and carcinogenic.

I use acetone, cheap and easy.
