My first Lens. Symmar-S 6,8 /360 in a Copal 3 shutter. What next?

Thank you Tin Can,

I have a retaining ring I just don't know what is going on with it. I might need a larger ring or I might need to twist the back and front together harder so it locks down. Or I might not understand how the retaining ring works. I put a video of it below. Hopefully it uploaded it correctly.

Um, er, ah, if I understand these things correctly the lens board goes between the rear of the shutter and the retaining ring, not behind the ring. The ring's flange should butt on the board.
