Thread: Hot & Shiny WIP

No nozzle tip but a little bit of a change in the diameter and surface as it goes through the side wall of insulation. It is just a piece of black pipe. I run mine at tank pressure no regulator, some of the other guys are using regulators I do not know what they are doing pressure wise.

It is just a piece of black pipe, air slots, mig tip letting propane in on one end, and welded to the other.

I always thought if I made another I would not weld the pipe on, but after seeing how well Dan's forge works I am not sure. I am beginning to think is 6 of one or a half dozen of the other.

This might change when fully insulated and installed but I does have me concerned.

I suspect that this is an orifice size thing. A smaller orifice will have a higher velocity for a given gas volume.

Charlie; Do you remember what size mig tip is in your burner?

I think my tip is .020-ish, I think Dan Graves built his using using a .030-ish. To me the biggest factors were length of pipe, and amount of air holes, then size of orfice.

In Belgium and Germany, it seems common to use propane or butane canisters to make a forge. They cut off both ends, mount it horizontally, coat it like above, and shove a burner in the middle. They do this because those canisters are very strong, and cheap. I have seen pics of Achim making wootz by setting one of those things vertically, place the crucible in the middle, and put a tile on top of the opening.

Most smiths I know here work this way. People in the arts and crafts business tend to use regular coal. So far I am the only bladesmith I know here in this area who uses charcoal.

All Fired up
1st was a cure run
Then heated to critical (non magnetic) a couple of punches which are now in vermiculite annealing so I can try make a makers mark stamps

Had a play with a piece of 1075 1/4"X1"x4" and forged this

In my opinion everything turned out. Congratulations!

Surprising how far the piece of steel forged out to
The tail is long and the blade is huge

If you quit now, you may not end up with the fatal disease. Mike warned me & I didn't listen...now I'm incurable. Moving and grinding steel is very addictive. You have been warned.

thanks Scott but there's no hope for me
so I'll take your warning & raise you by adding a Metal Fabrication & 1st class welder trade on top,
which I was hooked on the 1st time I had a go at metal work & welding in high school in 1984,
I loved doing the odd bits of blacksmithing in the boat yards as an apprentice.
& My grandfather was a life long trade Blacksmith.
so it's deep in my blood & I know I'm screwed,
now to add fuel to the fire, I have the bride showing things she finds on the net & would like made lucky most won't fit in my mini forge LOL
