I'm going to teach a 2 hour college class on knife forging and want to make a burner for Show and Tell. Its not a hands on demonstration but more of an informational for beginners as a hobby. I would like both the venturi style and the forced air type. Anybody have a favorite tutorial on the subject? This could help many people here.

A couple good ones there. The Don Fogg for sure. Anybody have more? Imagine that I was a newbie and wanted to build a small vertical forge. How do it do it?
 
Hi Bruce,

Not really a tutorial, but you might try the modified sidearm burner at zoellerforge.com. There're links to drawings and faq's that are helpful.

There are also some basic forge construction tutorials at that site.

Take care professor:D, get those kids on the right track, Craig

edit for being a knucklehead and missing the links mentioned above
 
Bruce, the modified sidearm burner shown in that tutorial is an excellent burner. If properly tuned, it will operate from 2# to 30# input pressure.
 
Bruce, I built my very first forge using this tutorial. The side arm burner is great. Very efficent and can hit welding heat easily with properly designed forge body. It's a great place to start but some day they will most likely want to move on to a forced air burner.

That is about what I was looking for. Myself use a mankel but need a link that the new guy could build a working forge, afforable and easy to follow instructions. This one is all of that. Thanks Rusty. :thumbup:

Do You have any forced air burner designs?
 
I always like to help a newb, "some helped me out and some still are"! Here is my list.

This next link came from fredlyfx.com and had been posted on this site. It is the design that mine was fabricated from. It has had burner angle modifications, courtesy of Ed Caffrey to create a vortex. The other modifications are of my own design.

I could not figure out how to post the design and I don't have a website, so I emailed a design for a hybred burner design. Feel free to share it if you wish.

Yes. Tall forge with a false bottom. Fully temperature controlled by PID. Holds +- 2 degrees of setting. Temp range is ~1200F to 2500F. Doubles as a salt pot. Remove false bottom to put in sword length salt pot. Bottom burner is used only when full length salt pot is in operation.

Burner is 14" of 2" black pipe starting at the 75CFM blower then reduced to 1" just after elbow. This config allows for good air/gas mixing. There is also a 1" pipe connector at the end of the 1" pipe as it enters the forge. The tip is kept about 1" back inside the 2" thick kawoal liner to protect it from melting. BTW, this is set up with natural gas running at residential pressure ~.25 PSI (yes 1/4 PSI). The orifice size going into the burner tube is 3/8". Ball valves for adjusting gas flow are also 3/8" as is the smallest orifice size anywere in line. Using NG is all about volume rather than pressure. Nice thing is you are billed on levels of usage. My gas bill does not change if I run this for 32 hours in one month (I'm a weekend maker). What that means is I run my forge for no gas cost and never have to fill tanks. :)

You can see it at this link --> http://www.flemingknives.com/shoptour.htm

Just click on the picture of the forge to see detailed views of the burner and control arrangement.

Hope this helps...
