Centrifugal shifting

gepponline77

Hi!
I'm trying to realize a centrifugal launcher.

It is just a cilinder with a threaded ring that rotat and i want the ring to be launched or unthreaded from the cylinder.
I can't understand which joint to use with the ring w how.
Can anyone help me?

I attach my project.

hi GEP

The probleme is not with the joint.

In first time , you need to make a pipe .
Please take a look on the next picture .

In a second time , you need to create a cylinder

Please , look at my file , centrifugal 2

if you'd like more explanations , take a look on these 2 topics :

So let me clear concept in my mind.

I have to create a cylinder not from a circle but with multiple segments?
Is this the only way?
No settings for the ring group to make it work as a real ring?

I noticed that if i don't group the ring with the cylinder, i can use a normal pipe, but the ring shift on the wrong direction, how to change it?
