Re: How to shorten screw?
cinch, I use a tool from Brownell's called a screw gizzie. It holds the screw and helps you gage how much you're taking off. I use a 120 grit belt on a belt grinder to shorten if it's just a little; like 1/8" or less. If it's more, I just cut them a little long with dikes and finish them up square on the the belt grinder. When I've got it the length I want, just barely bevel the new end of the screw to help it start. After it fits, I cold blue the raw end and rub a little gun oil on it. Works every time.
