Deckel Jig Grinding info needed

Does anyone have experience with adapting a Moore air turbine to a Deckel jig grinder?
If so, how does it work and what are some of the issues with this?
Also, how large of a hole can one expect to grind with reasonable accuracy and effort on a Deckel?
I am some what familiar with the capabilities of a Moore G18 and the Deckel seems considerably smaller.

I have nearly zero jig grinding experience, but have always wanted one and now I got one. (jig grinding head on a FP4NC).

Thanks for the info.
