Knife making process
Chainsaw chains and a flat 3/16" 5160 stock. (Picture 1)
Using an electric welder, I welded the chains to the stock (note
the cutting teeth) (Pictures 2 and 3)
I made a cannister with a pipe and I made a sandwich with the welded
piece and two layers of 304 stainless steel, one on top and one
on the bottom, to prevent welding against the pipe (so I can retrieve
the ingot easily) (Picture 4)
Cannister on the oven at 1300C (Picture 5)
Once it welded properly, I took it off the pipe/cannister.
Preparation on a new capsule, with an identical pipe, but this time
I cut it on the upper corners. (Picture 6)
I placed a 2mm thickness asbestos paper as antiwelding barrier,
as in this case, the SS 304 would be useless, as the brass would
weld with it. (Picture 7)
