Starmill Rotary Table Size Sugestions?

Hello Group,
What size rotary table would you recommend for the Denford Starmill?
I was thinking of a Vertex HV4 (100 mm) but I think it maybe to big?
Any sugestions?
Thanks,
SRG

A small one!
Why do you need a rotary table - since you can interpolate any hole size and use the existing axes to do pretty much anything a rotary table can do?
I can see using an indexing head as an additional axis - so maybe you mean using it with the axis horizontal?

Thank You for your reply Simon.
The table will be used for a fourth axis.
I decided to go for this table due to the Z axis limitation of the Starmill (115mm) with the intention of converting to CNC (servo / stepper undecided)

The Starmill Setup in case anyone is interested
I have converted the mill to use EMC2 and have upgraded the stepper motors to double stacked and motion control stepper drives.

The mill rapids are approx 1800mm per minute which is limited only buy the step / dir pulses sent to the para port.
Looking to upgrade to a Messa 7i43 card to improve micro stepping and velocity.
Will be posting images shortly.
Cheers,
Steve

That looks ideal! Particularly with the Myford chuck adaptor - you could do just about anything!
