I have some 2" wide x 16" long 1" thick flat bars that need a 1.5" wide x 3/8" deep slot cut out of them length wise on the 2" face. This would be simple but the walls of the slot have a 40 degree taper to them. Can i do this using the peel mill? the reason i ask is that its open ended and its also extremely hard material, i was hoping to use trochodial cuts. Any other suggestions on how to do this easily, without trying to find a special 50 degree insert cutter
