Hi
I wish to accurately measure a female dovetail so that I can make an order for a male counterpart to be machined.
I would appreciate some practical pointers on how to do this and what tools to use.
Thank you
John

What's the dovetail for (microscope, brand etc.?) He starts to explain it at 6:45 into the video.

BTW I needed to know the angle of a scalpel blade so I could make a jig to resharpen them for my paper cutting hobby. I made a cross section of one, then photographed it with my MM-11 setup, then used ImageJ to measure the angle. That technique seemed to work for me.
I made this 60 degrees for my Optiphot (not that it's accurate but worked).

PS: I'm NOT a real machinist so take anything I say with a grain of salt.

Many female dovetails have 3 clamp screws (e.g. Zeiss, Nikon). In those cases, you need very few measurements as the fine adjustment can be done using the clamp screws.
It's more difficult if you have a complex dovetail design (e.g. Leitz, Leica). The diameter at the plane where the clamp screw touches the male dovetail is critical.
If you have more information on the microscope, it'll be easier to help.
