Another small update: After further investigation of the 4th axis it seems I can remove the DC motor and replace with an absolute AC Servo to match the others, only 750W instead of 1.5Kw.

The old motor was a round flange type and the new ones are square but it's simply case of drilling a few more holes and tapping into to the existing plate. There is a seal on the plate that motor shaft goes thru and the pinion gear clamps onto the shaft using a collet type system. SZGH are making the shaft to fit the seal and pinion.

So when done it will back to all it's glory using the factory fitted 4th axis slimmed down with a nice shiny new controller, some extra grunt in the motors and spindle.!!! . . . . Well that's the dream anyway so lets see what reality delivers...
