He acquired from some mystery source a raising mechanism I just helped him install on one of them - I've never seen one like it - it consists of a gear assembly, an acme screw, and a bottom pillow block. the bottom pillow block can be clamped to the column, and with the top (gear assembly) and the table loose, you can turn the crank which through a gear rotates the acme screw and raise/lower the table - every other unit I've seen has a rack rather than an acme screw - so, for the group 1. anyone know who might have made this thing (there is no label on it, it's far from new - probably pre WWII to my eyes - can't find it in Sears catalogs, doesn't say Sears or Crafstman on it 2. any idea where I might find another for him? 3. any idea where to find a raising mechanism of any kind that would work on a 2 3/4 inch column? Sounds like some older Deltas and Walker Turners. Ive seen the screws on both. "They couldn't hit an elephant at this dist..." Maj. Gen.
