Well, you know, old age catches up with you - middle age, I guess.
(My wife says “mature”) Especially in our line of work. I’ve been
pretty well living under an optivisor for some time - #5 most of the
time and a #10 for real close up stuff. Sometimes I’ll use regular
glasses for something like polishing, where you need the wide field.
Lately I’ve had a problem, though: I weld a lot of platinum, for
which I need to wear welder’s goggles. I can wear glasses under the
goggles, but that’s all, and I’ve been welding more and more “by
braille” recently. I realized that I need ed to figure a way to be
able to weld platinum using the optivisor, if I’m going to get any
work done. Which I did, and I’ll share it here with you all.
I use welder’s goggles, not glasses, and they take a standard size
plate which is removable and replaceable. My plate is a standard 4
1/4" by 2" by 1/8" thick. I went to the hardware store, where they
have one of those displays of brass and aluminum tubing and such,
and I bought a piece of rectangular brass tubing of a width that
will hold the plate (5/16", maybe?
I just took the plate with me and tested it). The didn’t have
channel, or I would have gotten that. I measured a piece and cut off
one of the short walls to make a channel. Then I cut it, mitered it,
and made what’s essentially a three-sided picture frame, with the
glass plate sitting inside it. Then I soldered a brass wire on each
side, at the top of each of the side channels, with each end bent
into an arc. I used 3/16 (4mm) stock because it was handy, and I
bent the spot where’s it’s soldered on to get more reinforcement -
i.e. I didn’t just butt solder the wire, I bent it and soldered a
length of it on.
That may sound a bit fuzzy, but in the end what the whole
contraption looks like is a giant pair of eye glasses with shorter
earpieces, around 1 1/2" long. Then I drilled two holes into the top
of the optivisor for the hooks on the wires, and it just snaps right
in, holding the plate in front of the optivisor lens. It’s a little
tricky to figure the angle of the wire and get a good fit, but only
a little. Works like a champ!!!
