The relocation of the centre was badly explained. I dont think the machine had the rigidity to be accurate enough and the centre was the easiest place to spot this. But agreed, I have a lot to learn and yes, I dont know the techniques.
Erm well sorry but better being said than just thought and seeing you taking wrong route.!

When ever you have to flip parts and require more than 2 it's worth taking the time to make a fixture Jig. Provided the Jig is well made and indexed to a fixed known location you will always get back to absolute accurate position. If the machine is made from jelly then you'll still be back in absolutle position you started it's just the machine doesn't go there if it's wobblying about.!!
