Just a quick HI. just found you and can tell I will be back often even if I don't sign in each time.
We seem to share many interests. but not to the same level. such as I'd rather buy my lathe than make it. Mor time to play with it that way. 
I'm more focused on the lapidary and jewelry arts but want to start some machining too. Wife don't know this yet. 
Thanks for the site and will be seeing on the net.

Joe- you're running a big, floppy torch there. Just with flame pointed into a box, that's all. Look at some glassblower's torches. They use about 3 gimicks not to melt themelves 1) cooling: upstream of where the mixed (air+fuel) gas stream is lit, it cools whatever pipe it rushes thru; 2) once it's lit, the flame tries to propagate back upstream, but can't because the gas is rushing downstream faster than the flame-front speed. To make that happen the gas stream must be squeezed thru a smaller hole than the ducting, and the gas flow must never be slow enough so the flame can squeeze thru backwards thru that hole (until the moment you shut it down.). 3) once the mixed gas is lit, it passes no more torch hardware; it goes only onto the load or into the heat dump (open space).. So I think your flame tube needs small holes and some plaster insulation around it, and a way for you to ignite it inside the furnace but outside the tube, and another way to warn you if the flame sneaks inside. Look at the mixers in bar-b-q and home heaters too. They use the momentum of squirting gas to drag in some air, but you can use your fan insead, and run natgas in a thin copper tube down the center to the hole at the end of the flame pipe, which is in the middle of the body, not blasting the wall.. Not sure you want any air-venting between fan duct and flame-pipe. Look out, this thing could make mass quantities of poison CO, anytime there's more gas than air. Another good reason to want some blue flame and not huge billowing yellow with soot. Two separate flame-pipes, one for air one for gas, each with 1 row of tiny side-holes, running side-by-side with holes angled 45 in & up so the jets nearly meet, sounds interesting to me, and safest. too. I.E., don't even mix until you're read to be _hot_.

You appear to be my kind of guy. I too have several projects going on mostly for the same reason, too simply see if I can just accomplish it. Thats how I found your page. Now I have some more ideas thanks to you. Keep up the work my fellow jack of all trades.

Hello all,
I figure since the message board is so quiet that I would get rid of it and put a guestbook back online. Hopefully this time I won't get beat and spammed too bad. Leave me a note if you get a chance, I would like to hear from you.
