Title: Which burner for a small meltting/heat treatting ? T-Rex?
Post by: PekkaNF on November 25, 2012, 01:17:45 PM

Hello,

I was once trained by a gun-smith to make some knife blades and other woodworking tools and I have Sievert/Primus torches which I use for silver soldering and hardening.

However, they are a bit marginal for melting any quantity of bronze or bearing metals. My need is not big (pretty sure 90%+ would be around 100-300 gr of bearing metals or such.

Will 3/4" T-Rex be the ideal one?

Or would it be only marginal improvement over sievert? I have bit like this and some burners:

With the experiance i have had with propane burners buy or make the biggest you can .
You dont have to run it at 100 %
They are not difficult to build

 I use a Ron Reil type burner for heat treating and aluminum casting.  The one I'm using now is similar to the style shown on the  hybridburners URL , using a mig welder tip. 

 A couple of web sites to look over,
