Autopilot clutch lever replacement

The rest of the modifications.


The "D" shaped shaft hole in the original black lever was 5/32" diameter. Over time the hole had been worn round. I drilled through the lever and 5/32" shaft and inserted a dowel pin. That worked for awhile, but any dowel pin (or spring pin or cotter pin) small enough to go through the hole was small enough to periodically shear off, and it faithfully did.

A new lever was fabricated out of aluminium. It's longer than the old lever.



I didn't have a "D" shaped broach (a "D" shaped metal punch) so I created the "D" shaped hole as follows:

This has proved to be a robust and long term solution.
