I am building a Willard reproduction tall case clock. In a recent trip to the Willard museum I was told that the Willards commonly used this type of weight shell painted red on their clocks. The curator also explained that the shells were commonly filled with anything that would yield the required weight. I noticed that several places like Merritt's sell 'Tin Can' weight shells. I do not know much about them and how much weight they would hold. One I saw was 6.75 inches tall and 2.5 inches in diameter I would like to fit the clock with tin can style weights. By my calculations a cylinder of that size would hold around 12.5 pounds of #9 lead shot, so should be enough to to run a DL movement. Has anyone used this type of weight shell before? If so could you provide some advice on a couple of things? 1) the shells are a tin can with a wood stopper at the top with what I assume is a hoop protruding through the wood top. 2) this hoop, hook or whatever it is, must also pass through the bottom of the can in order to hold the weight of the filler material. Do my assumptions make sense, or am I missing something. Just realized that this post should probably be in 'clock construction' moderators, feel free to move it.
