Rotary table -- from spare parts

[oxotnik]

Made a rotary table for the mini drill-press. Rotary base is recycled from optical instrumentation; chuck is from a 6-in-1 combo tool. Chuck flange plate, vertical base, and horizontal base are milled from 6061-T6 aluminum alloy. Horizontal plate has a 10mm through hole that is aligned to a circular shoulder, that snugly fits the inside of the rotary base, making accurate alignment with the chuck possible.

Here's a small part made with this. 4 indexed holes 90 degress apart along the OD...

Comparison with a store-bought TSL100, which is too bulky to fit comfortably on a mini drill press ...

Nice work!

I like the idea of recycling stuff. Seeing that I work in the optics industry do you see that little rotary as being robust enough?

By the way love you little gage stand also. That might inspire me to make something similar. I cutting up some scrap steel plate right now to make riser blocks for my lathe, I might have some metal left over to make one.

...do you see that little rotary as being robust enough? ...

It's for fine-scale work, up to 5mm drilling and up to 2mm milling, light cuts, on soft metals, and generally for non-moving / non-precision parts. The rotary ring base is a Sigma Koki from Japan; copper and aluminum alloy construction intended for microscopes; very precise, only strong enough for light milling and drilling, or maybe some kind of EDM type setup...

Thanks
