Bill,
That’s an excellent idea. But it would take something with considerable density. In the system I’ve been working on I was planning on running a cable down through the column, through the bench top, to a cluster of 4” PCV tubes arranged vertically. I’d been planning on filling the tubes with lead shotgun shot, which would give me the ability to precisely adjust the weight (I was going to use a cluster of tubes rather than a single tube so that I can keep the vertical dimension down). Looking at the volume of a standard 25 pound bag of lead shot, I’d guess that there wouldn’t be room for 2+ bags (actually, the volume of same) inside the column – but that’s such a good idea that I’ll do some measurements and report back.
In the meantime, another problem would be keeping an internal weight from rubbing against the sides of the column. Anyone have any ideas?

Just to get away from the weak ceiling joist (rafter) thread
has anyone checked to see if a suitable weight could be hidden in the
column? In fact it might be possible to let a weight of half the mass
fall through twice the distance using a single sheave! Bill in Boulder
