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 made100% 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 than90psi shop air too. I haven't yet blown a freshly tapped chip into my eye, but I always do worry.
