After 20 some years of using an alcohol lamp and a dental tool
(knife shaped) I bought an electric waxer from J.F. McCaughin Co.
(Rosemead, CA). About $135. The unit has a rheostat that is quite
sensitive, but the tip ends of the pen are Fred Flintstone clunky for
delicate work, and the way they are set into the pen is cheesy, if
moved around just a little, the connections fail and no heat. I filed
the tip down to a more accurate point, but I am still not 100%
satisfied with the result. Meanwhile, I really like the idea of the
waxer, and wonder if anyone has a unit brand they are recommending
highly, and have used long term. Thanks!
