Have you got a lathe which will accommodate it mounted to the cross slide?
I take they are fixed.
How large is the complete thing. It's not all in the sketch as I see it.
How accurate do they have to be.
I can't quite follow that but it almost answers my query.I probably didn't make it clear the holes are already there just not square to the machined area and the arm is coming down on an angle runs out around 8mm over 300mm fall.
