No clock inserts unfortunately for me.
These are the quartz movements (Tubular Quad Chime Clock Movement) I normally use. They are not necessarily cheap but they sound amazing and also can be pretty loud. They are also fairly large at ~ 4.5”H x 4.75”W x 1.25”D.
Always fun trying to figure out how to hang them in the clock carcass.
This clock design is a beginner level woodworker project. Could be done as a weekend project.
