I'm a packrat, of sorts. I do alot of poking around at fleamarkets in the area and I'll snag stuff that find interesting even if I don't have a need for it right away.
I had an old Brass Bladed Fan in my garage with some major damage. The armature and oscillator mechanism was broken off, and there was no switch. I used the motor housing, blades, and cage from this fan.
To this, I added a brass pump insecticide sprayer (c. 1910) that had been gathering dust on a shelf in my shop for several years. I also planned to use the cast iron base to a lamp that I've always liked due to the face images molded into the pattern.
I tinker with clocks, so I had some old mantle clock feet that I bought off ebay with other parts a while back. I had an old sewing machine motor and a router speed control that I didn't use, so they went into the parts pile as well.
I ordered 3 feet of #25 nylatron roller chain and a couple of #25 cogs from Small Parts Inc.
I went to Lowes, and bought an oak board and a length of brass braided water supply hose.
