Yes its a fire extinguisher with a pipe that i drilled holes into,i use a balloon inflator for the air.Good stuff.I like the effect from the files..
Your forge set-up looks interesting too,is it an old fire extinguisher?(sp)
I tempered them until they reached a straw colour them dipped them in water to stop the colour going into the blues and purples..how hard should they be?

made something like that up myself from a file but think my mistake is I quenched it in oil it throws off sparks poorly....
Have you ever dropped one and had it shatter on you,i have so thats the reason to temper.Ive made a few of these and ive always heated them beyond the curie point for large grain growth and quenched in water.Ive never tempered them though.Funny Survival bill mentions poor sparks using oil...same thing has happened to me.Some steels are oil hardening,some are water.
It is a joy John for sureThe joy of hitting hot metal with big hammers!
My forge is an old Wok with an old tentpole as a tue...my anvil is a bit of railway line...my bellows an airbed pump.
One day I will upgrade......
