High pressure "beer" propane burner for oven

[syvmn]

I have this burner and I use it for brewing beer:

So far I have just used the direct flame from it to heat treat my knives. I know that this is very uneven and probably a very bad way to do things. I've seen a lot of the home made ovens that people make like such:

I am wondering if I could do a similar design but using the burner I already have.

I have always wondered if these home made oven are even. Its seems like the burner they have in them would directly hit a certain part of the knife and heat it hotter than the other parts.

If someone could clear this up for me and let me know if my burner could work I would be very grateful. Thanks!

Here is a thread where I asked a similar question about burner placement when building my new forge. http://www.bladeforums.com/forums/showthread.php?t=628532 Stacy provided a very good answer.

Iron pipe burners are fairly inexpensive and work well.
