In this video I will show How it's possible to convert a Non-Ai aperture ring to Ai aperture ring in old Nikkor lenses, with a home made wooden tool and a Dremel / Proxoon multi tool.

I will use the cameras aperture ring (F-0) and the lens mount to measure how the correct mark should be set in lens aperture ring.

Attention!
Converting the aperture ring in a lens is a NON reversal process, make
sure that you measure correct! and set the mark in the correct position.
And make the grinding very carefully! And work slowly.

You can of course also use a metal file to make this conversion.
