Design of a Hydraulic Buffer

[sluggo]

Greetings All;

Looking for some insight into design guidelines for making a hydraulic buffer. Volume of oil to be displaced, orfice size and qnty, spring force, etc. all need to be calculated in order to design buffer rate, stroke length and return for the required application. Rather than reinventing the wheel, someone must have a spreadsheet for running these calculations or a design guidleine. This concerns fire control for firearms...

Thanks and God Bless
