[TheForge] oxy-propylene

[Ben Barrett]

This is all *great* info... just another question, and a comment here.

Q:  What are the downsides of using a torch made for oxy/acet, with
propane?  Will I die or waste fuel or have no control, or what?  :)

Comment:  Screw Airgas -- *sorry* if they're your only choice.  I get
my B tank of acet, swapped along with a full 40 (I think, it is about
the same size as the B anyway) of oxy, for $25 total here at IWSI.
Right now that's about the same price as getting the 10-gal propane
tank filled... I've been told to avoid Airgas, unless your employer
makes the choice for you (even then...)
Curious about cross-use of hoses and such, I've heard re-purposing
*can* be safe, but that sharing should be avoided for this (ie, going
back and forth between different gasses in the same hose/reg/etc).

thanks!
