[TheForge] MAPP gas vs. acetylene

[Peter Fels & Phoebe Palmer]

I think Harris made a lot of the Sears torches Mike. Kinda graceless but functional. Parts might still be available.
Er....No one would publicly advise that you get a nice, small, comfy,old victor torch like a J27 or a 100 and take a comparably small , reamed out tip, cut it off and thread the end to fit your little end tips. That's the sort of crap i'd do.
I used to be able to butt weld 26 ga, but my hand has deteriorated a lot.

Ha!  We knew that. ;-)  Me too.

I got a Craftsman oxy/acet set in '67, before I got my first forge &
anvil.  The regulators have long since died and the cutting torch is
so-so.  But the welding head came with several tips.  The smallest one
has a thin extension brased into massive part that threads into the
torch head. That tiny tip can do all kinds of neat tricks, silver
solder, butt-welding sheet metal etc.

I've been thinking it's time to replace the aging set but whatever I
get has to allow continued use of that tiny tip.

Aircraft style torches generally have quite small tips available and are much more pleasant to use.
Low pressure torches like the Meco or the Dillon/Henrob run even smaller, but the Smith/Tescom "Little Torch" with the ruby tips are really, really dinky.

Um,, carbide tap? Localized temper draw?


BTW, still working on the 300# A&O which now runs well.  Does anybody
have a trick for making 1/2"x13 threaded holes in a piece of metal (in
this case, the upper die) if it turns out to be too hard to be tapped
in the conventional way?  I'm making a bolt-on attachment requiring 4
threaded holes in the die which is not so hard that a file glides of
but it files real hard.  If my retired machinist friend says he can
drill but can't tap, is there some trick with inserts or something
that I haven't heard of?
