So I followed the original 3/4" directions, substituting 1/2" for all 3/4", using a .23 mig tip and mine ran best with a 5" mixing tube. Once you have it together you have to adjust jet and tube length for your forge. Remember not to have the tube sticking in past the forge wall.

Darren, I'll look through my stuff and see if I can find the specs I started with. If I don't find them I'll get some measurements for you. As Alan said, a 3/4 will work, and if you decide to upsize your forge a bit you'll already have the burner.

I'm fairly new to the addiction and not any where as skilled as many on the forum. That said, I'd like to join the KITH if it ends up being something I think I have a chance at accomplishing. Design by committee sounds like an interesting option.

Fairly new myself, but...... I built mine with 6 bricks, so it's twice the width of yours but still pretty small. I used a 1/2" T burner and it works great. (It hits welding temps) I'm sure someone here can help you tune one to work perfect in yours.
