I picked up this 1946 oliver back in February of this year as a companion to my tenoner, and as a upgrade to the little jet benchtop mortiser i had.

We loaded it with a forklift and because of the height and balance point i ended up having to take the table and knee off to unload it. Overall im rather happy with its performance.

That’s sweet Jared! I love that style, looks like a mini version of my Cincinnati vertical mill. What kind of tenoner do you have?

Its just a millbury 106 (that still needs some work)

That’s cool! Does one motor run all the cutters? I have a beast of a tenoner- Oliver 125 pulled from a millwork shop. Haven’t used it yet but it’s all there and works except one thing- the cutoff saw for the last station is missing, gotta see about making one of those (or finding one).

Yes the single motor runs all 5 cutters.
(Not my tenoner)

I was just looking at a yates 2&1/2 (similar size to the oliver 125) but decided against it.

I like the small footprint Of your tenoner and if the Yates is made like the Oliver there are 5 individual 2hp 3-phase motors, not something you’d simply hookup a VFD to.
I’m still drooling over the mortiser (and your new jointer!) though!

I’ve got a PM hydraulic hollow chisel mortiser that hopefully stays in my shop (long story). Looking promising though

That is a interesting powermatic. Was the hydraulic setup factory?

As for the yates, yes individual 3ph motors. I would have had to finally install a PP or RPC to power it.

The American 2&1/2 is the same machine

Here's my thread about the mortiser on owwm, I have not confirmed with PM literature yet but it does appear to be factory PM from the 50s (best guess)
