[TheForge] Oxy/Propane reprise

[Peter Fels & Phoebe Palmer]

Paul;
There used to be a bunch of aftermarket torch tip makers, but i think 
American Torch Tip ( think that's the name) bought a bunch of them out.
On propane cutting tips and rosebuds, many are disassembleable so you 
can take them apart to clean them out.
