What clock are you making, 0.3kg is not a lot to power a clock, 5kg would be about right for a long case clock. I built a gravity escapement time piece for my daughter as a wedding present and when I realised the there was too much friction in the rear train for it to run properly it went into the dustbin! The next day it came back out but there wasn't very much worth salvaging so I started all over again and she got the clock on her fist anniversary!

Regarding the clock well you stop at the point where you discover it takes 5 kg to drive instead of the foreseen 0.3kg. By the way this does funny things to the drive train. What do you do? Well this *** clock is on the bench and will be converted to axles on ball bearings, the hot air engine runs on these and was a success. On the field of the steamboat engine there is hope. Finally seem to have found a suitable design for the boiler. It looks promising but the original still has to be tested and proved so have to wait till summer to see the outcome. Meanwhile trying to collect free time. I keep it in a bucket till I have gathered enough but there must be a hole somewhere in it. Regards Wilfried Vermeiren MODEL ENGINEERING DISCUSSION LIST.
