Notes and Changes:

Changed .1" internal radius to .25" at request of fabricator for machinability.
Changed corresponding external radius to chamfer to match .25" internal R.
Changed 1/6" vent holes to 1/4" MAX for easier fabrication
Changed lid screw hole depth to 1"
Updated various notes, dimensions.

Viton Pad is .25" x.25" x .0625"
Thin washer is removed from assmbly
