[DeTomaso] Brazing

[David Fisher]

Ah how I love the collective wisdom of the mailing list.   Lot's of good
advice.

I probably should have mentioned that I am using Oxy-Acetylene with flux
coated rods and I do get a popping and sizzling sound when things get
porous.

It seems that Larry has probably diagnosed it correctly..   I am probably
boiling the filler and evaporating one of the filler metals.

Thanks Guys!
