Forge Oven?

[GrahameA]

Morning All

Some questions for the cutlers, etc. I am interested in making a small gas fired forge/oven for making arrowheads.

a) Has anyone made an oven using Hebel blocks? I stumbled across some directions but I am unsure if they were using the equivalent of Hebel blocks.

b) Has anyone made a small gas fired oven? I only want something that will take a six inch length of steel or thereabouts.

This was a project I was looking at the other year and it has resurfaced.

Not quite the same but have you thought about contacting jewellers or especially SCA jewellers/cutlers?

This is funny I was going to ask about making a forge myself, but I would like to know how to go about making the burner?

Is a forge oven different Grahame?

Thanks Steve - and I had even seen that thread however, obviously the brain had forgotten it.

That is exactly what I was after. I will use a large propane torch as I already have one.

All it needs to be able to do is get the steel hot enough so it is malleable. I will be off chasing a Hebel block later in the week.

I have made a couple of gas forges and didn't find them very difficult.
My small model is a truck brake air cylinder with some holes cut in it, I cemented in some cut fire bricks with cement from the wood stove guys, and I made a burner out of some steam pipe and brass tube.

To make the burner I welded a 1 inch pipe to a 1 to 1-1/2 inch junction, then welded on a 1 to 2 inch junction, then welded a female thread to the 2 inch piece then inserted the brass tube in holes I drilled in the side of the threaded section. A short section of male thread is inserted to tighten down and hold the brass tube. The brass tube has a 1/16th inch hole drilled in the side as a jet, and the regulator is a acetylene regulator (the thread goes straight onto a LPG valve)

what were you planning on making in your forge. i use a coal forge myself, but i like the trad feel about coal. the blade smith that is teaching me to make swords has a gas forge made fron a old gas tank off a car. works real well.if you want to see some examples go to the following links. brouse the site it has lots of great info on it.

This might be too late, but unless your going to line the inside of the hebel with refractory cement, I wouldnt bother. The hebel started to crack from the inside and eventually broke in two although it still worked when I pushed it together and held it there.

I want a heavier duty forge that wont break on me after a few heat treats but every site I go to I find they line it with Kaowool? I have never heard of it before so Im not sure if its even availible in Australia?

Apologies if I am late and it broke already,

You can get kaowool in Australia, you should be able to get it from a welding/industrial supplier. BOC might have some and are quite wide spread.
