Nathan Creel's burners: has anyone made these??

[anvilring]

and... will they produce welding temps? My forge is up for a rebuild and I'm thinking of going with these. Easy to do and I have all the taps'n dies for it and plenty of 1/4" pipe. I intend to use new Itc100. I need to be able to come to welding heat so what do you think? anyone used this setup with any success?

I used a similar burner and it works well. With regards to welding that is dependent on forge size and number of burners. My forge is 7" diameter and 10" tall with one burner and I can hit welding temps.

I cheat however and attach a hair dryer to work as a blower rather then as a strait venturi burner. My pyrometer has measured my forge up to 2400F (I pulled out the pyrometer after that)
