 Note: When cutting metric threads, the
bottom gear must mesh with the 120T
gear of the middle gears. In order to do
this, you need to install the bottom gear
with the raised hub facing in toward the
lathe.

 Note: DO NOT overtighten the cap screw.
The cap screw merely holds the gear in
place and overtightening it will make it
harder to remove later and may restrict its
rotation.
