I picked this chair up the other day at my favorite flea market from a guy who always has a lot of vintage things, although usually they're priced higher than I'm willing to pay. Anyway he let me have this for $30 and I figured I couldn't go wrong.
It doesn't have any crack or blemishes on the fiberglass seat, and the hardware was all there except for a couple of washers that were missing where the legs attach to the bottom. The metal legs had the usual wear on the black paint, and the brass feet had long ago lost their brassiness and two of the four feet were missing the plastic tread. No big deal, I've been down this road before and I was pretty sure my favorite local hardware store had some feet that would fit it.
After I got it home it was a simple job of using a socket wrench to remove the nuts that were holding the legs on. I used some steel wool to knock off a tiny bit of rust and rough up the legs just enough to make priming them easier. I needed to know what size feet to look for so I tried a couple of my open-end wrenches until I determined that the 3/4-inch wrench fit snugly on the end of the leg. It took some WD-40 and a pair of vise grip pliers to get the old feet off by twisting them back and forth and pulling a little.
A trip to the hardware got me the new 3/4-inch diameter brass feet I needed ($2.49, a great deal!). Next I primed the legs with some spray primer and after that dried I used some Rustoleum gloss black paint. I have a cable out back for a dog run and it makes a great place to hang things I need to paint. After the paint dried I pushed the new feet on and reassembled the chair.
Looks good doesn't it?
