" any propane tank works"?

Yep, my acetylene regulator screws right onto a BBQ tank, no separate costly tank needed. Same LH threads on both type tanks.
Have used propane for the cutting torch exclusively for about 20 years. Only time I use acetylene anymore is the rare torch welding of steel, such as for lift rings.

I have done plenty of brazing and silver soldering with just a propane-air torch ($30). The best information I have gotten on technique is from "Soldering and Brazing by Tubal Cain, Workshop Practice Series #9" from Nexus Special Interests.

A few years back, we got a new BBQ and it had a new type of connector..
Will a standard acetylene regulator screw into the old style or the new?

I'll look it up and check it out.. I've done a lot of plumbing with copper,
so I've got a starting point anyways.. :)

Have you run out of gumption on this project?

I'm a bit distracted by other stuff now. My Solar back-up system, solar screens etc.

I'll get back on the repair, sooner or later.. Even if I can't do the repair, all the spare
parts on this leaker might be very useful someday.
