See empty socket in photo. I’ll probably use it for spare files since I don’t have whatever was there originally. I know the table bushing is missing too but I’ll make another in 10 min. Or so. The vert. Socket is a blind hole about 4” deep and maybe 2” dia., I didn’t measure. There’s a locating pin alongside the opening for whatever was there. There’s also a hex-bolt clamp ring to lock the mystery part in place. Motor is obviously a replacement but the thing runs well. Large knob under socket isn’t connected to it, it is for raising/lowering the file carrier chuck by hand.
