I have never used wax, got a lesson from Roger Dyer at a annual Mid-West Faceters Guild but still never attempted. I have been using Zap CA and epoxy, I don’t loose stones. In the transfer I have t let the glue set for a day, otherwise it will come off when removing the dop to cut the crown. I do use a 35 watt soldering iron to remove my glue, burn it off. I have used the iron for soft releases the next day that can take hours until the dop falls off, I use a cloths pin to help heat sink the stone so the heat does not get to my freshly doped pavilion.
