Gentlemen, you have probably been asked this question plenty of time.But I have been knife making for about a year now and I want to try something a little different. I have a majestic two burner knife making forge and I'm running a 100lbs propane bottle at 12psi. I cannot reach forge welding temperature (yellow or white heat). Even when I am starting with a piece of steal 3/8 or a 1/4 inch thick I still cannot get it any hotter than bright orange. If anyone has any advice or suggestions please fire away.
