Presumably, the withdrawal happens only when directed to "fire"
as a single projectile is emitted (not a multitude).

The end of the tube where the projectiles
come out is shaped as a scroll with a lip so that the projectiles become
free at a definite angle of rotation.

But, doesn't that just change the problem with a mechanism "catching"
to the *projectile* catching (the time between when it can escape
its constraints and when it is still withheld)?

The speed of rotation could be used to control the velocity and rotating
the outer tube to vary the position of the lip would change the launch

But, isn't that just RL's "sling" with an "autoloader" built in?
I.e., can't I just have a "throwing arm" fed by a hopper with
a collection of projectiles?  (likely balls of some sort)
[Though balls will bounce instead of just landing where thrown
(like on a sand court or beanbags in cornhole or water balloons
that self-destruct on impact)]

angle.  The whole thing could be made with a screw thread traversing
mechanism like the very earliest experimental Edison tinfoil
phonographs.

That would allow the cylinders to move relative to each other,
while one is still spinning?
I've several "linear actuators" that I used with the spring
solution.  I figured I could also use them to reliably position
bits of a mechanism (e.g., on a "pivot" or "extension", cocking
a bow, etc.)
