I recently bought an unnamed wall clock which came without a pendulum and after some advice in another post in this forum managed to make one which seemed to work fine. I've now gotten around to testing the clock more extensively and have observed some very strange behaviour. When I set the clock to the correct time and start it, after about 45min or so it has lost 7 mins. The strange thing is that it remains the 7 mins slow for days, i.e. it is not really running slow but just seems to lose the 7 mins initially. So I thought that I would set the clock 7 mins fast but in this case it stayed the 7 mins fast instead of what I thought would happen , i.e. lose the 7 mins initially and then stay at the right time. I have done several other adjustments, setting it both fast and slow but it never settles at the right time. I have dis-assembled, cleaned, oiled etc and re-assembled it many times but can't figure out what is wrong. Any suggestions would be appreciated?
