A few months ago, before I even had a mill, I was browsing a second hand store and spotted something under a pile of worn out screwdrivers and cordless drills without batteries that looked interesting. It turned out to be a 9 inch Troyke rotary table. It looked to be in pretty rough shape but the price was right so I lugged it's not inconsiderable weight to the front of the store to check out. The proprietor looked at it dubiously and advised me "All sales are final, no returns."
It finally rose to the top of my to-do list. Here is the starting point
It took me a while to get it appart. I thought for a while that the worm shaft was completely frozen in place. Turned out that the chain drive on the worm shaft had tightened the collar to the point that the shaft was completely imobile.
The internals were well oiled and in good shape.
After some Evaporust and a little paint it is looking much better.
I have a small handwheel I can bore out to fit the shaft and I still have to make a graduated collar to align with the existing vernier. I plan to bootstrap that, using the table to machine it's own graduations. 240 divisions with a 90:1 worm works out to 3/8's of a rotation per division so I only have to gin up a 8 hole dividing plate.
Oh, and the cost $10.
