Important fixes * (2019/05/27)
A person who saw this model commented that the rotation ratio of the long hand and short hand was not correct.
When I try to examine, in the as of the opinion, have found mistakes on the ratio of the gear train.
When the long hand rotates eight times, the short hand is designed to rotate once.
I think everyone knows, but correctly, the minute hand makes one turn while the long hand makes twelve turns.
I corrected this mistake. Files modified by gear60B and gear72B.
Since the size of these two gears does not change, it works correctly only by replacing with the old gear.
By the way, I am surprised that I did not notice such basic mistakes.
I am grateful to those who point out this mistake.
There may have been a similar statement in the old opinion, but I couldn't notice it ...
In the course of this correction, I also fixed the parts of the thread winding cylinder.I modified the wire to be less likely to get entangled.
***Update history(2019/06/08)
I updated the "outside-cylinder.stl" to the "outside-cylinderB3.stl".
B3 reinforced the claws of the hoisting ratchet and reduced it to two.
Replace the stl file without the B3 included in the zip file with this stl.
