Mark, I’ve been using the kind of alcohol you’re describing for
14 years-and never any eye irritation or any other problem. I
use it in my alcohol lamp for waxing, and in my flux mixture,
although not lead through the flame ???. Maybe I’m just lucky !!
I think good or even fair ventilation is crucial, and overcomes
most of our faults.
I think the tip about using a Sharpie to block off areas before
oxidizing is one of the best tips I’ve heard! Thank you!!
I’m in the process of designing a desk-top box of sorts, of
plexi- to contain all the dirt and metal particles I generate
when using my foredom. I also want to make a jig to hold my
foredom handpiece to use it as a lathe for wax work. I saw a
model for this in one of my books- but it isn’t very specific as
to how to hold it steady, or how to make a “live center” to
stabilize the wax stick on the end opposite the chuck. I’ve
looked around to see if I can buy a small one, to no avail. By
the way, for those of you in the Los Angeles area, I frequently
browse at a large shop called Old Tools in Santa Monica, that has
every imaginable old contraption, including foot-pedal scroll
saws, old watch-making tools, lathes, motors, wood tools, etc.
I’ve picked up all kinds of jewelry tools there, including files,
(old and new) punches, burs, drill bits, dental tools, etc. There
are hundreds of tools that are mysteries to me. Yesterday, I
found a very small bench top Foredom motor, with a sliding lever
on the side to regulate the speed, instead of a foot pedal. The
sheath on the flex shaft is worn at each end, but it still
works. I wanted to buy a new one, but haven’t located the right
size yet. I hope my handpieces fit this flex shaft. It was a
great deal if they do! Let me know if anyone wants directions to
this place. Be prepared to spend hours there!!
