It’s all about being smooth. To ensure graceful operation,
shape the arms by scraping & smoothing the edges shown
using a sharp knife or sandpaper. Do this for steps 1.6 and 1.7.
Scraping should
result in 45 degree
edges that are about
1mm in width.

Because the top screw of the “large lifter
assembly” enters from the back side, make
sure the screw ends flush with front of large
lifter (O). If it extends past, it will interfere
with the moving parts.
