Exactly, now the tuyere will some in right across the spigot/drain so if you want to tilt it back while melting it will pool without running out the tuyere. Be sure to have the tuyere 1/2" or so up off the bottom.

One thing about making it so it will tilt is the burner has to move with it, I just use a tiny little bilge blower and it is all munged together so I can easily hang it on the furnace.

Awhile back one of the guys on the old BYMC forum did a slick tilting rig where the CoG of the furnace held it in place tilted back and of course it sat level on its legs tilted forward. Just two positions where it would sit on its own then he could pour ingots from it using a lever/handle to control it between these two positions.

looks OK to me.
Mine pours from the other end of the tube, and yes the flame can shoot the spout if I turn it up.

sorry for the absence, took a week for thanksgiving, then spent a week sick from all the travel

Well the new furnace is done and properly tested, 10 inch bore with a 1 inch hybrid burner, cut my melt times in half.... 3/4 inch Kruzite GR Plus Hotface over1.75 in. Kruzite 22, a varmiculite insulater All I have to say i I need some new safety gear. It gave my faceshield a lovely warp, and the CHannel locks are no longer an acceptable set of tongs. all and all a Success. I still wish I could get those 45 minute brass melts people brag about, though I have not set up the oil burner yet.

Especially from a cold start, subsequent melts should go much faster and even faster still if you get a real good preheat on the ingots.
