One thing I should have done a long time ago was to drill the elevator horns. Before doing so I need to check the hinge distance. My plan was to insert a 3/16 rod through both hinges and simply measure. I made a tool out of plastic piping a few years ago to ease the turning of the rod end, in the same drawer I also a had a measuring block I now remember I bought on impulse...
Using that block made it super easy to get all the hinges set to the same distance which I set to 13/16.
I then started to look for the bushing I also got a few years ago (1/4 outer and #40 inner diameter). I found it and realized it was a few thousands to large to fit in the elevator bearing, so I have to rethink my plan.
