Initially I thought this would be an easy project but was immediately deterred when I realized that the side I had wanted to face up wouldn't due to to taper on the shaft.
Step 1: Fitting
Luckily their were three holes on the top in a small enough pattern that I could put studs in and clamp in vice.
Step 2: Feet
But there were already balancing holes in the bottom so I just tapped them and put in 5/16 - 18 bolts with rubber caps from ebay.
Rubber caps = Pool cue bumpers
Step 3: Harp and Lampshade
1x Harp from lowes
1x Light Socket (I used a porcelainized ceramic one because its mounting stud fit the end of my crankshaft better) from lowes
Most lighting sockets will have a threaded rod coming out of the bottom which was much smaller than the end of the crankshaft. I solved this by sandwiching a piece of rubber (roughly the size of the id of the shaft and 1-2"tall with a hole for the threaded rod) between two washers and a nut along the rod. So when you twisted the light socket; it would move down the threads and squish the rubber out to grip the inside of the shaft. Alternatively you could fill it with glue or epoxy, but it wouldn't be removable.
(Still in progress) Buying a lampshade would be the easiest way (which i still may do), but I decided to try to make one instead. The plan is to do it with a trimmed AC vent on the top, a metal hoop or ring on the bottom, and some kind of expanded metal pattern with a light diffuser behind it.(maybe like the last 3 pictures)
Step 4: Wiring
Step 5: The Finished Product
Don't know if i'll leave the pistons on, but they're easy o take off. (they are kinda fun to play with though)
I'll upload more pictures later with some kind of a lampshade hopefully.
Feel free to ask any questions about any of it.
