Pendulum Basics
Posted: Wed Dec 09, 2015 3:01 pm
Probably not new to many experienced clock makers but I'm a newbie so I'm excited to share some of my successes. I made a pendulum bob and a pendulum pivot modeled somewhat after a Clayton Boyer design. The pivot is a knife point and the bob is weighted with lead shot or BBs. The pendulum support is simply a 1/4" wood dowel with a flat filed on it and then a shallow V-groove cut into the flat. I set this thing in motion with about a 3" swing (6" side to side) with a 48" pendulum length and it was still going after a half hour with no additional input. The bob is adjustable with some threaded rod and the brass tube in the bob keeps the ballast away from the pendulum when the adjustment screw is turned. Now, if I could only figure out how to keep this thing going with the pallet using a crutch. If anyone else has some photos of how they did it, please post on this thread.
