Nitriding and crank grinding

I dont know the exact amount to remove... But, if it's .150" from each side you could have a radius made on it. Again, lots more cash tho as it's not really easy to do without being setup for it. The MP cast cranks are good. And again, the one designed to to that exact job and be 100% strong is cheap. There is no value in it, even with import duties you may have to pay. Any cast crank gets less strong by cutting. You're reducing the diameter by .333? I dont know the sizes off the top of my head. The factory specs a max of .040 to retain factory strength. You're only exceeding that by 800%. Why not :D?
