Rick,

Thank you for documenting the basics and explaining the logic for this type of XY table configuration with a rotary table. It is easy to get confused so sometimes I write on the table and dials with a marking pen to show which way is in-out, right-left relative to the milling tool and rotation. I have not tried manually machining curved spokes on flywheels but like your article on milling openings, I have read the techniques and would probably do it the first time in wood or plastic to make sure I really understood the movements.

Thanks for publishing this (and adding the Copyleft protection for sharing),
