Hi Brad,
I am including here some measurements of the square nut for your reference:
I have not been successful in finding any socket that would fit into the mirror adjustment mechanism yet. I am thinking now of finding some flat head screw that can grab onto the square nut. Then, file it off until it would fit into the opening of the mirror adjustment nipple. Something like this:

It is hard to find a screw that fit the square nut but I think I might have more chance of finding it than finding a socket that works.

HienThere are socket wrenches for square nuts! Try searching for "square nut sockets".Much more likely candidates will be "8 point" sockets. These are readily available and most probably in your required size.Please measure across the diagonal (for and along one flat side, obtaining two separate measurements and share those dimensions.We should also take care to know the inner diameter of the circular surround, but the socket can always be ground down to fit inside the circle.BradOn Sep 26, 2017 10:15 PM, "Hien Thanh Nguyen" <NoReply_Nguyen@fer3.com> wrote:Got it Greg. The Alan wrench method worked like a charm. My WP Sextant is working good now. The C Plath Sextant with the square head is a still problem. I hope that Frank can 3d print the tool soon ;)ThanksHienOn Sep 26, 2017 7:00 PM, "Greg Rudzinski" <NoReply_Rudzinski@fer3.com> wrote:Hien,
The W&P looks like a C.Plath Navistar Classic actually . The C&P is different but does share some parts. The 1.5 mm hex should still be a fit for the W & P. Worth a gamble.
