I got an ancient tire pump a few months ago. It didn't work, but I figured I
could fix it. It was butt-ugly but when I got it home it turned out to be made
100% of brass except for the main shaft which is stainless. The shaft was bent.
I straightened it, lubricated the leather, and plumbed it so the end was
1/8-27NPTF so I can use blowgun ends in it.

Boy is this handy to have around the shop for blowing out holes after drilling
or tapping! I just grab it and pump, way quicker than pulling out an air hose
and finding a blowgun for it. And the air stream is much less dangerous than
90psi shop air too. I haven't yet blown a freshly tapped chip into my eye, but I
always do worry.
