This clock was built last winter to see if bows were a practical method of power supply.  They do work pretty well but they take a set after a few weeks and provide less tension than when they were new.  In addition, the compound pendulum seems more sensitive to power variation and the clock js a very poor time keeper.  I did employ a fusee which helped but the fact that the bows change over time makes it very difficult.  Nevertheless,  It is a nice looking clock and demonstrates a number of interesting mechanical applications.  If I use bows again, I will use more fiberglass on the bows and add a rementoire to solve the power variation problem.
