the underside. had to mill the standoffs to get the right height & levelness.

made one out of 304 stainless. recommend buying one from Patrick1. this was a total PITA.

thanks for coming up with this great mod! may put some reference marks on the visible side some day.

made a @RockyAussie adjusting nut. the detent ball is a bastard to get back in. used small tweezers & a toothpick to push it back in its home.

nothing. this is fast. chronic tinkerer.

this cheapo winder counts the number of revolutions. got it on ebay. https://drive.google.com/file/d/1Qb2IGX69TvLqn1IBySZpNl7K3bSRVlO6/view?usp=sharing
