Someone asked if you can use mapp gas with regular propane torches, I
don't think so, someone may correct me. One difference in my mapp
torch is no adjustment. It lights, and is either on or off, no low med
high. I love it though. I recently had to replace the whole water and
heating system on our other home and used the mapp gas torch. What a
blessing that was compared to trying to heat with the propane,
especially on the heating pipe. I have never tried brazing, but after
reading this thread I think I am going to pick up some sticks and give
it a try. I am like you, I like to play with stuff, even if I am not
going to go pro;)

Have not seen one. Where did you get it, does it have a brand name I
could look up. As much as I like the mapp torches (I do a good bit of
plumbing for freinds and family;) I would like to have one that
adjusts. I got mine at L*wes home centers and they only had the one
kind. Thanks, Scotty

Benz-O-Matic, "made in USA". Has the adjusting knob and it has an
automatic lighter (flint stone, I guess). I got at a referigerator
supply store, people use it to weld/braze/whatever the piping to/from
compressor. I used it a few times to heat engine cases and wheel hubs
to fit bearings. Neat stuff, I think the gas will last me over 10
years... :-)

The Bondo or the JB Weld sounds like a good idea. Even after you fill it
up with something, your going to need some filler material to cover the
imperfections, just like body work on a car.
But the use of torches and such is more fun than mixing two compounds.
Good Luck! :-)

In the old days they filled dents on cars with lead... and that's all
you need. There was a guy once on American HotRod that showed how it's
done. Done properly with the soilder/lead you shouldn't need any bondo.

I guess it depends on the brand you buy, but I bought my regular and Mapp
torches at Home Depot and they both came with the same (interchangeable)
torch head.

Thanks Keith. I bought my propane unit at Home Depot too, so I
might be in business. I'll stop by HD one of these days and check out
the current offerings to see if the MAPP unit has the same sort of
head as mine. It'd be nice to have that option on hand.

What about some of that shet they sell on tv that plugs
holes in everything, just a little pinch, and sand over it
the repair would then be waterproof!

No offense, Jeff, but oxy-acetylene is considered brazing, not
welding, and
is definitely not strong enough for fixing a motorcycle frame. It's
fine for
fixing tanks and fenders or cutting steel, but not for structural
repairs.
The other three methods are far more suitable for welding a frame,
IMO.

I'd like to challenge the first part of that statement based on
this...

Definition of brazing
1 : to join two metals together through the use of a third metal or
alloy at or above 427 degrees C (800 degrees F). The braze material
alloys with each of the two metals that do not alloy with each other.
Leads and seal rings may be brazed to designated nickel plated,
refractory metallization areas of the package. [SEMATECH] Contrast
solder. 2 n : a material used for brazing, usually a silver/copper
(72/28) alloy with a melting point of 779 degrees C. [SEMATECH]

If all 3 metals are the same, it's probably not brazing???


I suspect the second part may be false or only 1/2 true as well, but I
don't know enough to prove it???

Not to revive this old but way kewl debate-

If all 3 metals have the 'same' melting temperature, it'll be welding.

All 3 metals could be brass, but if the 2 base metals were a higher-
melting-point alloy than the filler brass, it would still be brazing
as long as the base metals didn't melt.

Re: Brazing questions (don't laugh)

(From Wikipedea - FYI)

Soldering is distinguished from brazing by use of a lower melting-
temperature filler metal; it is distinguished from welding by the base
metals not being melted during the joining process.

So, brazing and soldering are the same, brazing is just hotter.
Eeeeenteresting...but stupid.
