How much money ya got sunk into that gun vise?
2 24-packs of canned soda: $6 each.
~20 feet of nylon rope from Home Despot: ~$2, max.
Add a few bucks for gas, I suppose.
Having a cheap homemade vise to work on your several-hundred-dollar revolver: PRICELESS.
Still looking at under $20. Not too shabby.
