I need to make some knives for cutting custom wood moldings. See this for typical profiles:
I have access to a very accurate heat treat oven but it is not atmospheric controlled. I can also access a surface grinder to clean up scale and warpage BUT the gibs quit working if I go down too thin.
I grind smaller knives all the time, no huge deal to get the shape I need on the grinder. This is the first try at these larger ones.
-What steel to use? A2, O1, W1 are all available
-can I get by with out heat treat? (Highly desireable to not deal with warpage and scale) If so, what grade of steel?
-Can I wrap the blanks in a carbon steel package rather than the expensive SS foil? (Some .008" steel could be flat formed around the blank with crimped edges)
-How about just hardening the cutting edge? Rough cut, harden, temper??, finish grind the last .010"
These custom knives are killing me for short runs to match some existing woodwork. $200 cutter for 100' of molding.
