I found the section of the manual but I did not help much as the button with the symbol that was in the manual was not on the DRO, anyway eventually found a button that did what I wanted it to.
For a laugh I thought I would quote one of my favourite passages from the manual:
"The god of the earth that points out that the obvious form of number provides the convenient ellipse halving hole function, handles person requires English to import an ellipse"
Don't ask me what it means, I don't have a clue, and I have spent many weeks in china deciphering Chinese/English conversations!
So back to the install... Here are a few pics(and yes the poor old mill could do with a paint job. The previous owner used something paint destroying as coolant)
