When our long case clock is running fully, the next job may be a small 'mantle' or table clock. Partly glass mechanism and all glass case. Timed by dual or possibly triple pendulums. This latter choice depends on my theory, regarding triples, being proved correct or otherwise.

The two pendulums are tentatively planned to be one second stroke. Using a 'compound' overhead design for compactness. Again this depends on the measured accuracy of such an arrangement.
