Weak point on the #2 besides the belt is the transmission.
Yours seems not quite in gear yet.
The lever lifts the entire motor and moves it to differing dia. flat circles on the driven side. This is done with a rubber wheel on the motor shaft and these rot and go bad.
Spindle teardown and rebuild is easy and super high precision bearing not needed, Keep the oil cups full not only on the spindle but on the slides.
The side to side axis usually good but the in/out has a tendency to crab. Assume you have found the fast and slow feed "button" for side to side.
This was my very first T/C grinder and I have the motorized workhead to use it as a OD grinder.
Problem as a T/C is that the spindle does not tilt so one has to get creative.
Not many parts in this machine tool and none heavy weight or complicated. I would tear it to shreds and clean everything.

It was in low gear when I picked it up. I tried to shift to other gears and it objected.
The belt to the spindle is not broken, but brittle and loose.
This is the "workhead" I built for my Hendy-Norton (a boring bar holder from an old Mori, bored out and bushed, the spindle is MT3), I guess I will throw a poly-phase motor on it for the cutter grinder
No, I have not found the button for ludicrous-speed, or a serial-number.
The No1 once had power feed. But the bracket looks shop-made, is on top rather than underneath, and is much to large. (see below)
Neither machine appears to have been operated in decades. The "shop" they came out of did not have a single chip on the floor, just old machines piled on top of each other, and not under power.
The No2 has a power plug for 3-phase as it should, but the catalogs I have indicate that the motor could be 220v or 440v, but the machine has no markings to indicate which - one more reason to tear it to shreds and determine what is in there...
The No1 has a 110v power plug, but the motor tag states 230, single phase
Both machines are sort of green, but very different shades. What was original?
