"True" wax build-up for models?


#1

Re tip shape:

The tendency of molten wax to pull back from a point is a nuisance.
Many years ago the Giles Precision Waxer was recommended to me. Otto
Frei now calls it their Ottowaxer. (Unfortunately, I do not have
experience with comparable models.)

This unit has two kinds of tips, spatulas and pens. The pen has a
groove down its point which brings the wax into contact with your
work. I have modified mine, additionally, for a much finer point. I
fix a piece of 20 gauge silver wire to the pen tip. Sterling is soft
but it conducts heat well and can be soldered on to itself. I taper
the wire to a fine point and the curl a tiny loop at the end, as
tiny as I can manage. The wax does not pull back from the loop.

Re wax wires:

You can make molds to inject wax wires of various shapes and
diameters. The resultant wire will be flexible for a while. They
will be short. The difficulty is in finding an injection wax that is
not too gummy to finish easily.

Good luck, Jon Abbott

Jon,

How exactly do you “fix” the wire to the pen tip?

Thanks, Marta
