I was offered (for free) a VHF TV yagi anntena w/ rotor. Question: would
this work a 2M antenna? With a tuner, maybe?

Only if you modify the yagi to resonate on 2 metres.
Here is a link that will help you:

The article on the TV to 2m conversion is on the ARRL Technical Info site:

It is a copy of the original article from QST magazine, and is only
available to ARRL members from that source.

Yes, it will work. I just tried it with my HT. From southeast of San
Diego, I raised a repeater on Mt. Santiago, Orange County, with a 75-ohm
directional VHF TV antenna and a half-watt signal. Santiago is 70 miles
away. Disclaimer: My location, on a small hill with a generally clear view
toward the North, gives me an advantage.

Then, I put the analyzer on that antenna and I was surprised to find the 2m
VSWR was 3.1:1, worst case. Losses through about 50' of cable from here to
the antenna no doubt helped my VSWR number.

There is some risk of using it with a high-power rig if the rig isn't
internally protected against operating into an excessive VSWR. Most are.

Start at a modest power and see what happens. That's what a lot of hamming
involves ... try it and see. Smoke is possible but not common.

Take it before they change their mind!
The rotor is a definate yes and 2 meter antennas are about as easy as
it can ever be with building antennas!

Even better, cut down an FM yagi, works great.

Designed to receive 54 Mhz to 210 Mhz ...

.... Not going to work very well unmodified.

Keep the rotor and get an actual 2 meter yagi. I don't mean to discourage
you from building antennas. But you would probably be gutting that thing for
pieces of aluminum to cut to proper lengths to make a 2 meter antenna.
