Hi guys, what would I need to make a precision turn table? I'm not after any motorised model just something that can take a bit of weight, let's say ~1kg in the center that I would move my hand. Or maybe there is something available that I could use this way? I used an audio one in the past but it's too lightly built and rocks. Thanks for any tips.
Thanks guys. Ended up getting a rotating tray from a chinese kitchen shop. Does the job.
@erik: went to bunnings first but they didin't have a clue. saw your post afterwards. Had a look at your bounce mirror project. Would those mirrors be good enough to use as optical flats?
Probably not - they are fairly thin so probably flex all over the place? The sites that supply them give some specs.
Thanks for the info Erick.

Thanks Steve. The turn table I got did the job for centering but now I'm going to need something very accurate that doesn't vary in level up and down when it spins. I'm going to have to go with a large precision bearing outfit I reckon.
If you gave us a bit more info about what you are trying to achieve or are planning to do with it, we might be able to give you more ideas about how to approach it.
As they say, if all you have is a hammer all problems look like a nail.

I want to shine a light beam at very low indidence on the schmidt profile of a corrector plate so I can narrow down its true optical center as I cannot rely on its OD or ID. They're not concentric. I can do a good physical centering for the secondary with a cheap lazy suzan arrangement but I need something a lot more precise to do the above.
I have an old set of forks for a LX5 in the shed. It could be made into a "precision" turntable. There is no hand controller but the motor drive should still work.
I can bring it to the meeting on Wednesday if you like.
