This thread is for Leitz optical rotary table info, pics, descriptions, etc.

I will start it with a description of the 20” optical rotary table that came with my Peterson drill press.

The lever operates a pair of hydraulic cylinders that either lift the table or lock it, not sure which, but in the position shown the table is free to rotate. The center bolt for the lever is actually the fill port for hydraulic fluid. The top button on the left turns on the light for the optics. Below it is a fuse. The crank on the right advances the table 2 deg. per revolution. The small knob on the crank wheel is for fine feed. The optics in the center read to 1 arc second.

The bottom of the table. Both hydraulic cylinders can be accessed. The oil reservoir for the worm and ring gear is at the bottom.

One hydraulic cylinder.

Oil filler, drain and sight glass. I am not sure what weight oil to use, but it feels like 75-90W transmission oil.

The small black plug on the right locks the screw assembly in place and adjusts lateral play in the screw (the plug is retained with a center screw that has a small lever, not shown). The assembly body is eccentric, so rotate it to adjust free play of the worm and ring gear.

The worm is about 2” diameter.
