Thanks.
I got a killer deal on some teeth and adapters from my favourite non-Cat independent. They had sat on the shelf for decades, so it was just short of a giveawy (plus I got a spare set of teeth). That will take care of the tips (if the rocks don't destroy the teeth and/or adapters. I was tempted to curve the face of the tynes, but that would make it tough to weld on a hard, round wear bar if it is needed. Have been struggling with using the square beam loaded in torsion or just move it up a little and make longer tynes that get pushed by the cutting edge loading the square in bending. Also thinking of taking the side loads out with tabs that push on the blade edge, eliminating need for any bracing on the two long tynes. I already have a pair of 2" eyes on the top of the blade face, 9' apart, so that is easy.
