How to make player stay on rotating part?

Whenever a player stands on my rotating part, the part moves below without taking the players with it. My goal is to make the part hold the player.

I tried 2 ways of doing this:

The first is just changing the CFrame angle of it (the blue part). I also tried using hinge constraints with attachments, but that didn't work.. It did hold me but it's so wobbly and keep rotating in different axises.. I don't know how to fix it (That's the black part)

Im just very confused

Any help would be greatly appreciated ! Thanks ^
