Thanks OZ, she may look good but is she hot, if I can build a flare mabye I'll try it out on the vise tonight. Nothing at all I could play with and read about this stuff 24/7. :D Not everyone is of this opinion though. :hammer:
Cheers

She's more than hot , She's hellfire. Cobbled together a flare out of a couple of old fittings, wasn't shure it would work, flares are not needed installed in furnace but for bench testing they are neccesary. Moved my portable vise outside and set up for tonight.
Flame pictures
1. Shortly after start up-carburizing flame
2. cranking it up-oxidizing flame
3. Nuetral flame to slightely carburizing-the flame we want for melting
4. Flare turned cherry red in less than 2 minutes after start-up. Here the leading edge is starting to turn yellow. For fear of melting it off I did not go any higher on my settings. Both the needle valve and the choke were less than half open.
5 and 6 are 2 more veiws of the flame.
Hot baby hot. :ddb:

Nice flame!

Hi Tom. I was surprised given how rough the flare was. I cut a 15* taper in the fitting but given the thickness of the fitting it only extends 3/4" into the mouth of the flare, it then flattens out till it makes the jump to the smaller burner pipe size. A proper flare would be a little longer with a full 15* taper. The burner was a little unstable at the bottom end (normal for this type of burner) but settled down as soon as I started increasing the firing rate and remained very stable as far as I took it with a nice steady evan roar.

Completed the patterns to finish the refractory pour. Did the big pour yesterday, the bricks have to be soaked in water before installation so they don't dry out the hotface to quickly and the uni-cast 70 has a short work time. This made for a pretty intense proccess and I forgot to take pictures. Left overnight to cure. Removed form and patterns this morning still a little soft so some of the corners chipped. To wait till it hardened up much more would make it very hard to remove form and patterns and possibly cause even more damage. Vesuveius morter is great to repair these touchups. The darker shiny spots is where I have just applied it.
I will let this all dry for another 3 days then I will periodicaly fire it for a couple of days till I reach red heat.
Cheers
