I use a flattened upright hammer shank, sanded much like a screwdriver. This goes through a hole in a baby food jar to rest in the glue but the hole is just large enough for the shank to go through so the excess glue is squeegeed off the shank. The flattened part of the shank determines how much glue you get. The hole in the jar helps prevent evaperation and skimming. Just remove the jar from the hot water and put a holeless lid on it. It will keep for weeks and weeks and can be put into the microwave for ten to twenty seconds and you have glue ready to go, almost instantly. Use the stick to put the glue on, smooth it out and scrape off any excess. You will still have to check for glue at the end of the bushing cloth. I use a X-acto chisel blade which also allows me to chisel off any excess felt that gets down into the hole. I haven't felt the need to heat cauls but I do set some weights on the cauls (not a lot) and leave them in over night, as Ron said. Next to no easing BUT you need to pick your cloth so the caul fits snug in the hole during gluing. How snug? Snug enough that you have to push it in but not so snug as to split a sharp mortise. Those mortises were cut in the key factory. It would be wonderful to get some of these piece so we could unbush keys more quickly, accurately and size the holes perfectly, all with one plunge. Anybody?!?!?!? Newton
