It was much longer than I expected as well, especially since they were random no-name bearings.

A pendulum degrading in 24 minutes only needs 1/3 as much restoring force as an 8 minute pendulum. I hope to post a video soon showing the complete results.

FWIW, I tried a couple with mineral spirits: the problem is they seemed to gum up a week or so later...some kind of residue attracting cruft in my garage. (The stuff they sell here in SoCal doesn't look/smell like the stuff I remember from my youth.)

"Gunk" engine cleaner worked a lot better, except for the hassle of getting it out of the aerosol can so I could really soak the bearings.

Finally completed my laser-cut acrylic take on 'Zinnia' after letting the plans and parts sit for almost five years...
Did some re-engineering, mostly to get all the parts to fit the 12"x16" limits of my laser. Wheels are 20", which is about as big as I can segment one up without a ton of waste.
