Clock Forum

Thanks for having me,

I finished my medium Crazy Clock about a week ago and it has been running flawlessly. This was the first time I tried bi-color silk filament and I love the way the gears change color as they turn. My picture doesn't pick this up well. I also love how quiet the clock is. I can place it anywhere in the house and it doesn't annoy anyone. Thanks Steve for another great design! This is my third, the other two being the Easy Build wall clock and the Coupe Perdu.

After trying many combination of pawls on the electromagnetic clock and not being satisfied with the results.   I came up with the idea as shown on the video.  I redesigned the two pawls and reprinted them. As you can see I added a 3mm screw to each pawl.  The top pawl screw can be adjusted to only allow the pawl to stay engaged in the ratchet wheel for just a portion of pendulum swing and then the pawl disengages.  As the pendulum swings back the top paw can ride on the 3mm screw head of the bottom pawl.  This screw is also adjustable to prevent the top pawl from dropping into the second tooth on the ratchet wheel.  The weight on the bottom pawl is a magnet only because it was the right size and weight.  This weight allows the bottom pawl to pull back the ratchet wheel.  Moving the pendulum by hand, adjust the top screw until the ratchet wheel allows the bottom pawl to drop behind the ratchet wheel tooth.  The amplitude of the pendulum is no longer a problem, low batteries or fresh ones. I have this modification on both of my EM clocks and they are keeping very good time.  Leon
