So I decided to start a sticky to copy posts about simple mechanical procedures.
Here's the first:
Postwar Young spool end play
the run-out screw in the center of the latch plate.
Disengage the pawls and the spool should spin almost like a top.
the run-out screw in the center of the latch plate, tightened against the spindle tip, should allow just the slightest end play.
Tighten it until the spool starts to bind, then back it off to where you can feel that it's spinning freely.
There is the possibility of a bent latch bar.
This will show up in the runout adjustment as a the spool feeling free over most of the rotation and then binding up in one spot, or as a difference in end-play versus the rotation position.
