Here is an HC spike knife I made from a spike off the rail bed near Crystal City, Manitoba. I like to forge a spike or two as a warm up before I forge a hunter or a bowie. Hope you like it. Sorry about the size of the pic. My computer skills aren't as good as my forge skills
Hey Cal, Love the burner. I made a new vertical forge from a hundred lb propane tank & used 2350 degree kao wool. I fired it the first time without any refractory & the wool ended up looking like toast, so for sure it is able to be more than enough for the higher volume forge. Just wish I had more time to use it.
