So im planning on building a forge. Tye dimensions imma be running are 24 in long with 22 in roughly inside work area 8x8 inside dimension, so 12 in overall hight and width running 2 in insulation. Wondering what i should run for burner sizes, 1/2 or 3/4 inch, running 3 burners spaced even through the square box im makeing custon may go 10 inches wide too just a possibility due to the pokers i make can get wide at times if i run out of heat wile pounding. And also was thinking bout doing 3/8 or half inch plate for the outer shell of the forge itself would that be heavy enough with the insulation. thanks for listening to my jabber jaw
