OK so it is slightly more accurate, Leo would say its a lot more accurate
( I would have done as well when I was having to work to that sort of accuracy)
I only asked because there is always something new to learn, the method I use has always been accurate enough for what I do & will continue to be as I work mainly with wood & that sort of accuracy won't really gain me much but it is nice to know that if I ever need a more accurate method one exists
Took me a while to learn that wood is always moving & no matter how accurate I try to be the wood always seems to outwit me
I don't consider it to be insane, people do what works best for themselves & if that method gives you the confidence in your machine then its right for you.
