Now looking for a brazing kit

G'day Folks,

Anyone out there with experience of heat treating metal?

Before I take the plunge and just buy it and give it a go - any recommendations for good manufacturers of torches? (Non oxy)

You don't normally use a gas torch for this.
Heat treating - Wikipedia, the free encyclopedia

Brazing - Wikipedia, the free encyclopedia

Brazing - Google Search

I own and use an oxygen acetylene torch for brazing, silver solder, etc.

I've read that using oxy+gas torches is not only very expensive because the heat is concentrated to a very small area but it is seriously dangerous with solders that contain cadmium (see link below for source).

I'd love to have an oven that would be hot enough for heat treatment but realistically for my budget (as I'm just messing about to see what can be achieved at this stage) I reckon I can get by with some fire bricks and a gas torch. I've got plans for this out of this book.

Soldering and Brazing (Workshop Practice): Amazon.co.uk: Tubal Cain: Books

I think I'll probably have to go down the propane (rather than butane) route with a fan assisted air supply - but if I can get by with a self blown butane powered torch I'd be happy with that.

Any temperature high enough to braze releases the cadmium.

A forced air ventilation system for the welding area is important.
