I am curious what I need to coat a wooden ring mandrel with to keep
molten wax from sticking to it when I’m building up a ring shank
using molten wax?
I just wrap a piece of wax paper around the mandrel–wax side up.
Heat the seam with heated tool so that it does not slip around.
I have been taught to wrap some aluminum foil (the cheap, thin kind)
around the mandrel and then to lightly coat it with dishwashing
Silicon stray will work fine for this.
I put masking tape on mine. The wax sticks to it just enough.
Try a thin layer of vaseline
Put shellac or some kind of lacquer thats suitable for wood evenly
over the whole wooden mandrel, no wax will stick. Or purchase one
