In Printed Clocks
Hello! I am about to embark on my first printing of the SP12 Crazy Gear clock. This will be my first experience clock building! In addition, I was interested in making some modifications to the larger gears so that they have a more classic gear appearance. For example, my modified gear2-36-8: The tooth profile remains the same. However, this will add weight to these gears, on the order of an additional 65% to 70% increase on average. These are the gears I plan to modify, along with the weights reported by my slicer: gear2-36-8 - From 26g to 44g. gear3-36-8 - From 32g to 51g. gear4-36-8 - From 27g to 48g. gear5-36-12 - From 31g to 50g. gear6-32 - From 16g to 32g. gear7-36-ratchet - From 43g to 68g. gear8-36-8days - From 77g to 125g. The total weight change (based on the slicer info) is going from ~252 grams for the normal gears to ~418 grams for all the modified gears, for a total of ~166 grams of additional weight. I would note that I did not modify the escapment gear. My question is: will this increase in weight prevent the clock from running, or from remaining accurate? I intend to run it at the 8-day limit. Would I simply need to increase the drop weight to compensate? Or do these gear weights have any bearing on the clock at all? Thanks! Tim
