I built a wood forge in a old wheelbarrow, and had a good hot fire. I started running my knife blanks through my forge. All was good. My steel is old truck springs. They flattened out real fast. I went to drill my holes for the pins and found out that I couldn't drill through my knives. So back into the fire, took them out when they were orange, yellow, red. I ran a magnet over them and they would not stick. I started to drill my holes and couldn't drill them. My question is did I do something wrong?
Went back to drill a blank and after my 2nd hole my bit started to howl. Question #1 Did I do something wrong? I did hammer a few rail road spikes down into knives.
Question #2 If I make a small fire brick forge and use a map gas torch, will get my blades hot enough to heat treat?
Question #3 I have been told and read that I need to heat oil up to 130 deg, and dunk knife into it to cool down then run it into a toaster oven at 400 deg for 1 hour and let cool then back in for 1 more hour. Does this sound right?
Today I want to make a mini forge out of fire brick and a map gas torch. I would like to heat my knives up to heat treat them. Will this work for heat treating, and for taking out the temper? Thank you
