source for oxyacetylene tip
 

I'm trying to increase the efficiency of transforming lead from expensive rods to puddles on the garage floor (or even getting some on my 68 911 rust-bucket in the process) and can't find the appropriate piece to go on the oxyacetylene torch. According to the helpful leading video, it has an opening for the oxygen to enter. I have been using a propane torch which works, but does get kind of heavy. Any assistance in a source for such a tip or even what you call it would be greatly appreciated. Thanks, Tom

I have a tip that is referred to as being a "rosebud tip" have also seen it called other flower names. The idea behind it is that it has a rather large output for the flame, about the size of a rosebud or a tulip. It is designed that way so you can heat the surrounding metal at a body seam, plus the center portion produce a flame hot enough to melt the lead solder into place. It is also used when you "plank" the newly sealed seam, the tip is used to heat the seam overall so you can then smooth it down with a plank. Are you using any type of flux? It the metal free of rust or other contaminants?
Advice: GO SLOW, USE THE PROPER FLUX, DO SMALL AREAS, TILL YOU GET YOUR TECHNIQUE DOWN AND THE GAS OUTPUTS HOW YOU NEED THEM TO BE ABLE TO LEAD SEAM FILL A CAR.
Good luck!! Tony.

I forgot to say that you can find these at most any welding supply house. There is even a wide fan tip for your propane or Mapp gas torch. I will accomplish the same desired effect.
