Well I am getting closer! There is either an inconsistency in the gr per inch of the steel, or in the machinist. Maybe a little of both.
Here is a pic of the three I have made so far.
from top to bottom,
388gr 3 1/4″
240gr 2 1/4″
175gr 1 1/4″
I also took the rasp to the shelf of the bow, to put a radius in the front and back, so see if that helps with this cursed nock high issue. Nothing else has cured it.
I sprayed it over with some clear poly, and will rework the way the shelf and pad contact the arrow.
