Hien,

The C&P uses a 1.5 mm hex wrench.

The C. Plath wrench will be hard to find. Try small tweezers to get adjustment close then record index error on or off arc.

Dear friends:

I wonder if you could help me?

I have two old Plath sextants and would like to be able to obtain the tools to adjust the mirrors on them:

1. CPlath sextant: this seems to have a square head screw. Please see the pictures here https://drive.google.com/open?id=0B8AuUsHvUgZjS0M0VXBRNWdfTXM

2. Weems Plath sextant: this seems to have a round head screw. Please see the pictures here https://drive.google.com/open?id=0B8AuUsHvUgZjaXI4VGk5OV9rdTA

I have looked high and low but can't seem to be able to find the tools for them. I have also sent to Celestaire.com to see if they can help me but I still have not heard from them.

Is there anyway that you can adjust these mirrors by using tools readily available from home depot, or can you buy them from some where?

Thank you for your help,

Hien
