Dereks brother here ( who did most of the work really ;-) ! )
It's a VDI30 turret and just about fits considering the diameter of the tool plate and the clearance of the tools over the front bed way when pointing down.
If we need to part off to centre any thing larger than 45mm dia, we'll have to be very carefull about not bashing in to the bed with the parting tool.
Though this shouldn't be an issue as we've soon have a larger lathe for the bigger jobs .

Thanks for the info, the one I am getting, or may be getting is only a VDI20 which is smaller than I would have liked but it is 16 position which is nice.
I know the feeling of having to be careful, having a rear and front turret can be a bit of heart stopper at atimes when running code for the first time

The new lathe wouldnt happen to be a blue XYZ would it?
