But seriously, this whole exchange leaves me now wondering if it is best to clamp my guns horizontally or vertically when applying grease to the hinge pins.
Would that be muzzle up, or muzzle down ?
O.M
That would be "muzzle down", especially if you're using your "Butt Crack" as an improvised vise.

You aren't calling him a butt crack are you? Butt cracks everywhere will be insulted.

Nah, just trying to inject a little levity when things appear to be getting "edgy".
BTW, proper operation of the vise is preferably a two person operation. Since the crank is easily manipulated from the front, it helps to have someone else operate it. That leaves your hands free to apply grease where ever you think it's needed. The problem is that if you don't have a wife or girlfriend, the process can be expensive, depending on the quality of Labor desired.
