Any good adhesives for gluing wood and metal together?

Epoxy: check West Systems for good information on how to bond metal & wood (they've been doing it for boats for years).
Urethane glues, whether construction adhesive or Gorilla.
And as stated above, abrade the metal to enhance the mechanical grip. Also, don't clamp hard because you'll force the adhesive out of the joint and starve it.

If the joint is going to see force, or flexing, use screws and / or bolts also.
Wood does dry out over a period of time, so select a durable variety.
Avoid woods like pine and eucalyptus, they give off resin.

I would use epoxy applied to clean dry surfaces after using abrasion, as above. Clamp / support while setting.
The other glues ...no experience, never tried them.

Frankly, I do not understand the need to glue them together, maybe a cabinet?
In the old radios, the chassis was fastened using screws to the wooden cabinet. No adhesive was used, IIRC.

So, if possible, enlighten us about the project.
 
I think epoxy is too hard the glue should be a little elastic I guess....
Epoxy is used on flex surfaces like fibreglass, carbon fibre, ply....fishing rods, just get a suitable one man. If you are worried about flex, just pour some on paper and when set, bend the paper. Nice easy test, most epoxy will bend like plastic first

But I use a clear, non-expanding PU glue to attach small bits of metal to other things. Like a disc of metal to the end of a wooden handle for trim

Don't rough up, just take the shine off with genuine scotchbrite. This does sciencey things that I am too slow to understand to electron alignment things for a better grip, then just roughened up. It's called water break free surface. Spray some water on the prepared surface and if it clings in a film, you are ready with the best possible painting and gluing surface. This isn't exactly secret knowledge, and I am aware of a number of professionals in the boat building who will advise roughening up but use water break free themselves

Prepare wood to a clean surface using sanding sealer and do a final light wet sand followed by some brite on it too

But don't stop thinking, regular epoxy is easily cooked by heat. Metals make great heat absorbers. If it's going to get hot, than use PU. I have done boil tests on both and most PU that I have access to handle 100 degrees Celsius easy. I do boil larger items to dismantle an epoxy joint 😉

My apologies for contradicting both you and I. In this application, epoxy is an easier and better solution. Why, think again. Epoxy is designed to be machine spreadable e.g. a rod lathe. The turntable is a natural lathe and will make the task of applying epoxy easier. Use a stiff brush and clean up with white vinegar
 
Epoxy?
I wonder how many kilos are used in a 787 airplane, which is largely composite...a good choice for bonding.
The quick setting ones may not be as strong as the regular 24 hour curing varieties.

In a turntable, I would calculate the mass of the screws, and the damping factor distortion, then make my choice.
You do need a gasket, to fill the gaps.

Now, the material used for the wood, there are many choices.
A heavy steel platter, with a cork mat may be better, if well supported on elastic rubber bearings.
Those will be good for isolation.
