I tried heat treating an old junk shop knife with a 220000 btu Tiger Torch, but it didn't work which kinda suprized me.. So it looks like I'm building a forge. I have a metal pail that is 11.25" wide x 13" deep. I'm still going to use the tiger torch and have a piece of 3" tubing, I think is exhaust pipe. Now my question for the day is, where to put the inlet pipe ? I've seen them in the front and in the back, most likely in the middle too. One fellow on ytube said the front is best because the flame is where it was most accessable. What do you think ??? I found a place nearby that sells firebrick that I will use for the front. It was a off white orange color that was quite heavy. The firebrick I have seen elsewhere was white, quite light and you could drill and cut it fairly easy. I guess this orange coloured brick will work. Any thoughts ???
