Went to Harbor Freight and picked up another box of rubber gloves and a new air hose, since my last one sprung a leak. Oh well, I got three years or so out of it. I also installed a swivel thingy on the output of the air regulator, to keep the hose from trying to break off the regulator's outlet fitting.
As is usual when I go to Harbor Freight, I couldn't resist buying something cheap that I didn't really need – this time it was a drill press vise for nine bucks. And, as is typical, it's really crudely made. I followed John's advice and replaced the rusty, jagged steel jaws with thin strips of wood, which makes it way more useful for holding aluminum airplane parts.
