Greetings,

I'm in search of any documentation or blueprints on hard gages used to dimensionally verify the feather and base geometry of type "D" style valves. I recieved a set of valves that I need to machine and lap back to accepted tolerances. In leiu of hard gaging, any sort of blueprints specifying the working tolerances for the feathers and bases would be highly appreciated.

Best,
DC
