was your tip conical or just square cut
I have seen some machined on the inside to 5° helps as well as some that just use a 3/4" to 1" reducer for the tip and nothing else ?

Mine is not flared. It is just a straight bore with a step at the end of the 3/4" mixing tube. I gather that the idea here is to reduce the velocity and that the step actually helps by introducing turbulence into the larger diameter.

Very, very nice!

todays Progress another hour spent on it before it got dark
trail fit with threaded rod, ready for mounting of bolt flange lugs & the burner stab






internal view of stab end shaped to suit the inner walls shape


Flared my tip then ground the outside to fit my stab pipe
1 practice / spare and the finished item
amazing what you can do with a 50t press and a ball peen hammer




stills need a clean up but a step closer
may get to tacked it up tomorrow arvo if work doesn't get in the way

Looks real nice substance. My thoughts are that after you get it lined it looks to me like you will have trouble keeping your work out of the cone of the primary flame. I may be looking at it wrong, or I may not know what I'm talking about. I guess finish it, light it, and take a look. Without seeing the shape of the cone, it's hard to tell.

sorted my adjustable Jet System today
I have used a hazardous area cable gland, 1/4" instrument tube & compression fitting joiner currently fitted with a #35 (0.9mm) MIG tip but might have to actually buy some smaller #23 (0.6mm) tips if I need them. which won't be to bad considering the current build cost LOL



now just need to chase up my Son in-law (a Gas Fitter) about an Idle loop & some gas supply connections to hook up a bottle.
then I can hopefully start the magic Blue light of death on the weekend & try tune it.

Also I decided I'm not going to tack the Forge body or anything until I have the Burner working & confirm the flame size as I may reduce the burner size or the insulation to only 1" & take the access forge from 3" to a 4" opening??

Good plan. Also the burner will likely operate a little differently when it is in the forge. You may also be able to recess the burner nozzle back into the liner a bit and create a tapered port with refractory cement.

hopefully this video works of the burner running

Update
work on the forge was halted due to a big week odd on 12 to 14 hour days,
But POETS day today & got 3 hours spare so fabrication completed on the forge for now,
Obtained enough Superwool 601 to do 2 wraps of 1" thick.
A friend is keeping some refractory aside from a shutdown this week, so should have it in the next week to finally complete the forge ready to melt & smash some steel next weekend

Ok enough yibbaing here's some photos

Looks really good! You have a number of cool features that I will incorporate into my next build. Thanks for sharing.

BTW, I wonder where you got the idea for the anvil ?
