That's downright scary--oil fires are nasty. And burns from oil that hot
(I've had them from cooking) take a long time to heal.
I've heard plenty about the big 30-quart propane-fired turkey fryers
catching fire. I'm not so sure that I'd like to try your method, although
it sounds interesting.
Is synthetic automotive oil flammable at desoldering temperatures?
When I'm removing the bottom bow cap of a large tuba, I simply put the
entire bow on an old propane barbeque grill that has the bottom rack lined
with firebrick. No direct flame and the result is that in a few minutes of
heating the big assembly falls apart. I may try the same setup to desolder
an old board to see if it fares any better than a torch.
