Yeah seen those vids, its a nice tight job he did there. I modified my quill connector so that there is more meat below the screw - this takes the down thrust and eases the strain on the bolt a lot.

Tenths LOL, I love those discussions :) Having said that, i am really pleased how accurate my old girl is, plenty for my needs. Lately i had need to asses my probing accuracy, its only a basic probe with the three-point contact setup but i get repeatability of around +/-0.03mm which i think is pretty good for a conversion.

All good fun :)
