The mother of all 3-in-1 tools!

Wood?Wonder what they were making.

It's a Sears planercrafter.

They are making a pull roll for some kind of processing machine.

We used to plane shafting like that to produce a knurl finish to pull paper into the box machinery.

Later machines had knurled rolls, or replacable adjustable knurled "heads" on the finished rolls.

If that was a turn finish it would be bright
like the ways in the background, or the radius on the base of the machine.

The motor looks like a primative auto index arrangement.

The trip dogs are set to reverse the machine
at each end of the shaft.

Those old planers, and new ones, had a gear-rack feed mechanism that wouldn't feed slow enough to turn with.

That's what I think anyway.

The book, Machine Tool Operation, Pg 96 has a picture similar to this of a "Roll" being machined in a planer. It looks like a long roller with longitudinal slots around the OD.-Jerald

I wonder if this planer isn't being used to polish hydraulic cylinder rods such as they existed in the '30's. The motor rotates the work and the table reciprocates - both coordinated to produce a crosshatched finish. The job is progressed through grits of abrasive paper held under the work by a loop of leather belting clamped to the tool.

Polishing long work on a lathe produces abrasive that inevitably falls on the bedways. Traversing the carriage while polishing long work results in the carriage lapping tiself to the ways no matter how careful the lathe hand is. Performing this operation on a planer results in the abrasive falling on the table where is collects and from which its easily cleaned afterwards without the need to interrupt the work while its in progress.

I once saw a set of large long arresting gear cylinders honed out on some heavy cast iron machine tool floor plates temporarily installed for the job. The big plates were to provide restraint from the honing forces which were large. A 30 HP lathe headstock used to rotate a big honing head (20" plus as I recall) and this rig was mounted on a planer table to provide the 20 ft+ reciprocation. It took some inspired sheet metal work and a couple of 30 GPM pumps to provide the volume of oil necessary to flush and cool the job.

The work area was called the "skating rink" or the "pig pen" cepending on whether oil splash or squalling and groaning from the hone dominated the misery of working nearby.

In the floor next to the planer. It looks like slideways and racks. Would that have been for some sort of gantry type crane?

Doesnt look like a permanent solution, maybe the new lathe's shipment was delayed
