Had a look at the front turret today and still not sure if it could be used or not, will have to dismantle it a bit before I know.
The front flange of the shaft is 85mm dia where mine will be 80 but that in itself wouldnt be an issue as it would have to go on the outside face of the turret plate rather than inside like I had planned. Where the problem would be is the holes for mounting on mine I have made at 65mm PCD and the front turrets is just 60mm. Having said that it looks like the shaft may have the flange bolted to it as there are 3 cap screws in the centre, if that is the case then I should be able to just make a new flange up for the front the correct size to suit my plate, also I should be able to shorten the shaft first so that I can have the flange inside as I had originally intended. The only other thing I see that could be an issue is the coolant ring, I wont know until I dismantle the turret whether it would be possible to make a face for it to fit in.
Well on to the turret plate, after looking at the front turret I saw that the curvic coupling half that attaches to it is fixed from the front via cap screws, this makes sense as they are larger dia holes than the m8 capscrews and that allows you to clamp the turret and then with the screws slack you can tap the plate round to perfectly align the tool slot with the axis. So today I did the same to my turret plate, I bored the holes right through to the face and then took them out to 11mm and then counter bored the front of them by 13mm depth and 18mm dia, this will allow me to have a 4mm thick washer and still have the head of the cap screws under the surface.
I also made the coolant ring, at the moment it is 20mm thick but I will turn it down on the lathe to approx 15mm thick but I will wait until I get the turret built up to get an exact size.
