Oxy / Propylene Torch

Today's topic: "Have you used an Oxy / Propylene or Propane torch with any success?

I was making a new valve wrench for my water shut off valve. Using 3ft long rebar, I flux welded the T for a handle and cut a piece of 5/16" thick chain link in half to use as the end of the wrench. Turns out it was a bit small and did not fit over the valve. I have an oxy / propane torch set (inherited), but need the gasses and was thinking of heating the 5/16" chain piece and bending it open some.

I even thought of using the torch to weld some items when the flux welder won't do the job. I read some articles about the oxy / prop torch and it seems to have mixed reviews as to what it can do.

So, before I buy the gasses, I thought I would see what you all's experience with the torch might be.

Thanks!

Oxy-Acetylene gas welding and braze welding with Acetylene.

Learned from one of my instructors .. his hands were shaky as fuck but as soon as he picked up that torch it was like a surgeon ( all while he explained how he built Intel's infrastructure in the early 80s. )

What was the question ?

Awesome. Some people make a difference in this world.

LOL... "never mind" as Emily Litella would say....

So, DA me realized I could take a large, thick pry bar and pound the u shape open more. That worked great!

Never seen the fiddler on the roof.

Oxy propane burns almost as hot as oxy Acetylene .. usually metal is heated until its red hot to make a bend. Same with welding; when the metal is red hot the appropriate welding rod can be fed and worked into the molten pool to make a weld. Molten metal follows the heat. The downside is that gas doesnt last long unless you have big bottles or a bank of tanks.



The school i am working at right now has a small weld bay - this is for the auto body repair portion of the shop.

As for the T handle; my employer has several "home made" varieties in different lengths and sizes, but its basically what you made except with a section of square tube steel welded on the end.
