Response to yup just came up again and Ron Has a fairly simple rig design to do it

This is an electricians tool which can shear off screws to proper length stop I do not have one but have used one stop I believe it will shear a screw size up to 10-32 stop Anyway, the force to shear a 10-32 with such tool is not all that great as even a scrawny caveman can to it stop

Soooo, IF I had one of these tools, I would extend the handles about 18 inches by sliding two lengths of tubing over them stop To determine the force required to shear the 10-32, I would place one handle on a bathroom scale and push down on the other handle so as to get a scale reading when the screw shears stop Then I would back figure the MA to determine the actual shear force stop
