[TheForge] Burner angle

[Jerry Frost]

Hi Harry:

How you mount your burner is pretty much up to you and 
what you want it to do for you.

Mounting the burner perpendicular to (aimed directly 
at) the far wall, floor, etc. of the forge will result 
in a hot zone. There are advantages and disadvantages 
to this. First a hot zone means there's also cooler 
areas so you have direct, immediate control of heat. 
Simply by placing your work where the heat is right. It 
also lets you keep part of the piece cooler while 
another is hotter, ths is good for welding without 
burning thin sections as easily.

The downside is the uneven heat in the forge chamber 
makes things like twists and heat treating more 
difficult.

Mounting the burner(s) tangentally to create a vortex 
will even the forge temperature considerably, NOT 
perfectly but considerably. The upside means everything 
you put in the forge will come to about the same temp; 
this is good for things like twists, scrolling and heat 
treating.

The downside is the forge will heat EVERYTHING to about 
the same temp so you have to plan carefully so there 
are no thin sections formed early to burn off.

Neither is inherently better than the other and 
certainly not the "RIGHT" way to do it. What you choose 
will depend on what you need and what you need is 
likely to change over time. The really good thing is 
once you've made a forge or two you'll discover just 
how easy it really is and will find yourself either 
reconfiguring as needed or just making what you need.

it ain't real.
