    Chip trays are a plus.
    Big parts, a lot of chips.
    But not until it's loaded in the machine.
    I'll take the jib crane and hoist; that has unique construction.
    Practically guaranteed though, none left in existence.

    And that shaft hook, it cantilevers with a yoke above shaft, and slings balance from below!
    Does Jon award Tool Of The Week posthumously?

    *2. Went back for another gander, 1904 but not a lineshaft shop. The motor drives a cogged belt, with the headstock gearing under or in the lathe bed? The headstock proper IS in the middle, tailstocks and carriages at each end. Chuck is actually a trunnion bearing.
    Well worth examining full size. Enhanced maybe, but they still can't improve image beyond what is recorded. Incredible detail.

    A slightly newer version; with conventional drive.

    That old Putnam lathe was made in the same town where they made the early Iver Johnson firearms.

    Looks more like a single sided chain than a belt, similar to a 'silent' chain.

    I only see two spindles, one @1-1/2" the other @3/4". Not exactly what I would call gang drilling.
