Agreed, but a small weight around the post and at a large leverage, would mean small movements to achive a large effect, considering we are only looking to change drop time from say 4 seconds - 2 seconds maximum. food for thought.

The equiv of a small weight able to move inside the post and towards the bottom.

If the weight is equally counter balanced around the axis of rotation, it will have no effect on Dyn.Bal.
Also Droptime has NO effect on Dyn.Bal, only on how obvious it is. - The position of the gimble on the post makes no difference.

So a round weight (like a thick tube) around the post, sliding up and down the post would work to adjust droptime without effecting Dyn.Bal.

You're absolutely right, Mikko. In my head, I had somehow included only three masses, so something was missing (there would be four if a round weight was added). Thanks for clarifying.

Thank you Mikko,
For saving me the trouble.
