Nice even flames! Well done, A little rich maybe, it shouldn't have the blue flame drifting out the opening but that's just a little tuning. Easy peasy. Don't sweat the orange in the flame that's the calcites in the refractory oxidizing. 

A few chips in the outlets of the holes shouldn't make much if any difference. 

Nice job, I like it.

Thanks. You guys did all the hard work figuring out how to get this far

How would recommend tuning it? Just trimming down the mig tip to get more air in? Its a home made T burner from 1" pipe and a 3/4 pipe as we couldnt get a reducing Tee.

I fired it up again tonight and this thing is hot! The whole forge internals are glowing at 4-5psi after 10minutes. Happily sat there for over an hour.

If I turn it up above 15PSI it hums like what Dan's did

So here is my attempt at a NARB. 

133 holes at 4mm. We used mails with the heads cut off to form the burner holes. The refractory was probably a bit green when we pulled them out as some nails chipped the top surfaces as they were removed but it still works fine.

This is it running at 5PSI

This is running inside the forge at 5PSI. The refractory was still curing so we didn't run it for long
