Doors. I bought a pre-hung front door to replace our old nasty one. Frame was square, plumb, got the jamb square and plumb, and it's still binding at the bottom on the hinge side. I've shimmed it every which way and it's tolerable, but not perfect. Is there some magic trick to these things I don't know about?
Also, I managed to stick a rusty nail in my hand and now it's hard to bend one of my fingers. Oh, and the TV receiver died. It's nice to have such problems
