    Default Rebuilding a "Mystery" rotary table ???

    Hey,
    does anyone recognize this small (table a bit under 200mm diam.) tilting rotary table? it came to me within a lot of Russian made Soviet time machinery i bought recently, but this seems to be of different make than the other stuff. It has a logo that says "VF" and it has a stamped marking S20 on some castings. It seems to be well made with high precision, it also had german made bearings inside, so worth rebuilding if possible...
    It is however missing the main table drive wormgear (location of gearseat visible in last pic of underside of table) "presumably broken and removed by the previous owner" so cannot measure it to produce a
    replacement. if anyone recognizes the model and has any info how to locate parts or figure out the geometry of the missing gear it would be greatly apreciated.

    That is a bad problem to have, looks like it has some nice features. I like the covered dials. Good luck and keep us informed if you are able to bring it back to service.

    I think I would look at adapting a gearset that is "close".
    Possibly one from a current production 8" or similar size. You might have to bore or sleeve the driven gear, and adapt/graft the shaft on the worm.
