Map gas torches?

[Yosemite Sam]

For what it's worth;

A few weeks ago, I needed to heat a hydro drive shaft because I couldn't drive the pin out (hardened pin, like on a Narrow/Wide Frame hydro shaft) (that bat turd was really stuck, was using a 3# hammer and couldn't get it to move) I was at the other place and didn't have an oxy/acc torch there. I propped a propane torch up and laid the shaft on an old wire milk crate (please don't call the milk crate police) and walked away from it for 5 to 10 minutes*. When I came back, the end of the shaft was red and the pin drove out easily.

So the long answer is, yes a propane torch will get steel hot, but it takes a long time. Those little bottles are fairly cheap though, so using one for a long time isn't a big deal.

If you had to bend steel that was very wide or thick, I don't think you could ever get it hot enough though.

*I did this out in the driveway where there was no danger of catching anything on fire, even if the torch did fall over.

I also think the torch probably has more to do with the amount of heat output than the fuel (screw on propane type torches).

I have a Benzomatic TS4000 and not sure of the model number on the other one, they both get a considerable amount hotter than the "pencil tip flame" torches.

Doesn't look like it'll bust the bank.
