I didn't say yet to my personal budget accountant I HAVE TO but one. When I say I need two this can mean starvation and sleeping with a dogs outside :heehee: . I replied to her today: Rotary table wasn't expensive 10 or 20 £, but I forgotten exactly how much I paid :rofl:

Agreed...

You mentioned self centering 4 jaw. The advantage of it is 4 jaws clamp the stock more firmly than 3. For a given clamping force you will mark the part less with the jaws as less pressure per jaw. Not being able to hold hexagons is annoying as holding nuts in the chuck is a good quick way to hold a bolt without marking the thread ... but you're not going to want to do that in a mill.

I have a 4 jaw independent 100mm and 3 jaw (125mm) for the rotary table.
Being able to centre a part in the 4 jaw chuck is not much of an advantage as you can tap the chuck into place on the rotary table.

A chuck with bolt holes in the front makes it a lot easier to mount.

That's mandatory
I thought to buy from RDG http://www.rdgtools.co.uk/acatalog/L...SOFT_JAWS.html are they any good?

The fact is my rotary table have 4 t-slots so it looks like 4 jaw chuck with 4 front mounting holes as well will be perfect couple

Yes it does all depend on what you want to do with it.

True, but it's not really hard to make a backplate is it...

I have a 200mm 4-jaw self centring chuck on my lathe, TOS brand. It's very accurate, but that's probably not an issue on a rotary table.

I have a bit of 6mm steel plate in stock. Do you think is it thick enough ??

As long as you don't need to tap it more than M8 I should think so. If there's a fair few bolts then it can't bend much. If it was on a lathe you would want more.
