Can someone identify thread relief constants for sizing thread chamfers and reliefs? I have an old table that provides two thread relief constants, A & B, based on pitch. Here's a similar chart: http://www.bjg-design.com/designbook/thread_reliefs_htm.htm

Currently have a fabrication drawing for a rubber gasket, Buna-N, 3/32" thick, 60A Durometer. Machine shop is fabricating the gasket. The edges of the gasket are not smooth and the thru holes for mounting fasteners are not clean (looks like a razor knife was used to cut).
What can be noted on...
What is the most appropriate method to specify NBR material on a gasket fabrication layout? Currently, the drawing identifies Buna-N, however given the fact that there are a multitude of "recipes". I want the most oil resistance. I was thinking of specifying the grade and class, for example...
Utilizing a 3/32" thick Buna-N gasket between cover and housing that contains food grade mineral oil. Gasket is machined to conform to shape of cover and for screw thru holes. Noticing that during disassembly, the gasket loses its form and becomes very wavy. Suspect it is absorbing oil. Is this...
I am having a hard time trying to understand how a fabricator would inspect a part dimensioned like Scheme A with tight angular tolerance of .06 deg. I expect that the inspection tools would need to be an order of magnitude better than the tolerance. Can you provide an example of an inspection...
Requesting some input from the community regarding dimensioning of plate arc segments. Design requires fabrication of rings comprised of individual plate segments. Segments will have edge preparations and will be welded together. Careful dimensioning is required to ensure arc segments during fit...
