I mean to hold some 2x4s steady while I cut em. We're talking a walk/landing area about 10-12 ft long that leads to the stairs. It's only about 2 1/2 to 3 feet in width and is comprised of maybe 20 or so individual boards. Some of them are getting a bit rotted/bowed, figured I'd replace the whole row this year. Since they have to be cut to size, figured it would be easier to hold the 2x4s steady in a vice for those cuts after I measure. Probably get 3 usable pieces per plank. That's what I was thinking anyway. I'd just as easily use a sawhorse and c-clamps though, agreed.
Also, all this vice talk reminded me of that scene in Casino.
