Thanks to the poster who mentioned McMaster-Carr. I ordered my 12x12"
titanium screen yesterday and it came today! The timing was perfect,
because I was getting ready to sweat solder a 4-layer 61/2" bracelet
The screen worked mostly great. It did bow and change a bit from
flat, most probably because I was putting a lot of heat just on one
3" edge section. I think I will cut it in half (with what, I
wonder?). It won’t be so unwieldy and I can try to minimize the
bowing on a smaller piece.
It didn’t seem to act as a heat sink at all, and it’s strong and
stiff enough to be able to put significant pressure on it without
deforming it. And it’s a flat mesh, as opposed the the thick "woven"
ones available in steel. This is a much better form.
I do a lot of heavy sweat soldering, and this sure looks like the
best solution yet. I propped it up on 3 firebricks temporarily, but
want to figure out a more stable way to support it about 6" high (no
tripods!). Any ideas?
The thing was pricey ($100), but I really think this may be the
answer I’ve been looking for. For you too?
