Hey Doug,

yeah you have several meters of spindle ways and several rectangular gears in some of the bigger doors (Cleveland for example). Yet, you as a user of the door have to be able to turn the dials as easily as possible. Even on my small door the spindle way is about 400mm and I have two sets of gears for each lock: One rectangular and one gear for the offset of the lock. If you take a big module for the gears, I guess you can reduce the play between them.
What are your thoughts on this?

Best regards

Maik
