Being that one of my knives on my chipper broke and I am a cheap son of a bi%#@ i need to make one. Its approximately 1.25" x 3.75" x .250" thick, with two 5/16" countersunk holes in it and a bevel of 37 deg ground on one long edge.
For the time being I used a old but unused heavy duty mower blade which was as hard as a leaf spring is, and cut it to size and have been using it, but it does not quite hold up as good as the original blades did, but its still useable.
The original is supposedly hardened to 58 rc. So what materials would you recomend making this blade out of.? I don't really have a temp controlled furnace, but I maya be able to acccess one, unless I can get by on heating with a torch or in my crucible furnace.
Any info appreciated.
