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.
gear5-36-12Â - From 31g to 50g.
gear6-32Â - 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
