Another way of getting flamed!

Good plan.

Good point.

So called 'professionals'. ;-(

Well, you can get things pretty hot with even cold air, as NASA know with heatproof tiles. ;-)

And what if you have plastic covers over the metal ends (that don't come off)?

I have a small hot-air gun I use for heatshrink tubing that is pretty hot but gives a fairly well focused column of air. If I want similar with even more heat, then the heat gun on my SM reflow station should do it. ;-)

If I can find my GD glasses, I'll check out all those fitting numbers and see if it's that they don't fit me (and if I can adjust them) or, without having the hooks that go right round your ears, they are just too heavy for my usage / expectations (eg, expecting them to stay put like these all plastic readers generally do)?

It is hot air that is caused principally by a shockwave that created the need for heatproof tiles.

I never could run that fast.

Yeah, you would have to be going some if you were still wearing them and may then have nothing to hang your mask on! ;-(
