I've recently purchased a new 7x14 mini lathe & decided to make an adapter for my sick Coronado PST so I can convert it to 90mm scope.
The adapter allows PST body to attach to 2" focuser.
The project started with 55mm aluminum offcut.
I have no experience with lathe at all, so it was a fair bit of reading before starting the project.
For a total noob I am quite pleased with the results. Had a lot of fun making it.
It's not perfect but it works.
Here some photos from start to finish.
