The hole at the base of center pole and in rotary arm is 1.5mm. Should these be 3mm holes? It looks like a 3mm shaft should run from the top plate to the upper arm.

Thank you for telling me. When I checked the file, as you told me, the hole was too small. Actually it was 2 mm. I modified the file to make the hole size 3.5 mm.

very interesting and nice design!and thanks for sharing your design.I started printing the parts but i couldn't find any gear named 60B and 72B. after downloading there are gear60 and gear74, there is no letter B attached to them are they the corrected ones?or i should check somewhere else

Hello. Although I corrected and uploaded three stl files, they were not reflected in the zip file.
However, downloading from a separate list will succeed.
I have corrected three files, "gear60B.stl", "gear72B.stl" and "outside-cilinderB2.stl".
I would like to download these three files separately and replace them with the files without B or B2 included in the zip file.

Very nice model! Just got it assembled but haven't ran it yet, went together very smoothly. One question, how come the minute:hour ratio is 8:1 instead of 12:1?

Wow! Thank you for telling me. It is my basic design mistake. I made a mistake in calculating the gear train ratio.

I plan to find out and fix the design notes, but it may take some time since I can not get time now. I'm sorry.

Wow, fantastic work. I certainly want to give this a try. Are the gears pressfitted on the axes or do they need to be glued? I aask because if I make this in PTEG instead of PLA it is very difficult to glue petg.

Thank you for seeing my CLOCK.

Most gears are pressfitted to the shaft. However, the cylinder-inside has a large torque when hoisting the string, so if you are concerned that the cylinder-inside and the shaft may slip, you may fix them with glue.
I do not know the material named PTEG, but the hole in the center of the cylinder-inside is made a hole deep enough never to slip.

By the way, "HIQ-TOKEI" tended to squeeze out a little earlier than the standard because the reduction ratio of the escapement was inadequate. To improve this I uploaded "center-pole" extended by 20 mm. The upper-rod, lower-rod and vertical axis must also be longer by 20 mm. Sewing-thread also needs about 130 mm in length.
(Anyway, after assembling the clock, you need to make adjustments to work in the correct time.)
(Center-pole-longspilal.stl is a type that reduces weight by making a cylinder mesh.)

Thanks for your reply. I’ll take all your comments into account and will post my results as soon as I finished the clock.
I saw a clock like this one for the first time in florence in the museum of leonardo da vinci and I used the mechanism to make a little automaton.

Esta genial¡¡
Impreso pero no he conseguido montarlo, si pusieras unas instrucciones seria estupendo para torpes como yo ;)

un saludo

Gracias por verlo.
La temporada presente en Japón es fría en invierno.
Por tanto mi 3Dprinter es frío y heladas:)
Quiero hacer un manual de cómo construir si vengo para ser capaz de conseguir el tiempo.
Me alegro si espero un poco más.

160x160mm Printbed (parts fit´s on it)

Hey! The Clock was very nice for me to make, becaus of its special design (I never see this model bevore)
I like it, that you make the construction in a way that no tools needed to mount or dismount the Clock, thats beautiful :)
(At first I was astonished by your wedges, but that's a very good solution.)

The center pole was a little bit tricky to print. but i print 2 at the same time, so that it have time to cool down.

It is hard to find the Clock with the Thingiverse Search. I try it several times and dont find this Page.

Maybe would be good to chose a longer Title so that it is easyer to find.

Thank you for an opinion.
The principle of this escapement is not my original.
I referred to the old clock which I looked at at a museum in old days.
I think the similar clock to be able to find even Web.
Because the principle was simple, I was able to understand me immediately.
I performed the concrete designs such as a gear or the housing originally.
The title expressed Japanese pronunciation in the alphabet. It is the meaning called the clock that a ball flies.
If there is some good idea in the title, please tell me.

so how long does the clock last before needing a rewind? great work !! keep it up

When I use a 150 centimeter-long thread, I think that it moves more than 24 hours.

It seems like the length of the string is more important than the amount of weight for calibration to accurate timekeeping. Is that true?

If so, maybe there can be some wind-up area for the string on the swing arm to allow the user to increase or decrease the length of the string easily.

thank you for your opinion.
Probably your thought is right.
The accuracy of the clock is decided by the length of the string.
The adjustment mechanism of that purpose may be necessary.
I glue the string together in a scotch tape on the swing arm. So I can easily regulate the length of the string.
As a result, I decide timing at the weight of the weight. It lets the volume of the water in the plastic bottle increase and decrease and performs it.
This is because a gravity moment delicately influences it.
Continuously operating it is difficult, and time may be still out of order more than one hour for 24 hours.

Great design....do you have a video of it working??

Nice to meet you. Thank you for seeing it !.

I uploaded a video.

It is version 1.5 to work.

advance slightly early.

(The adjustment is in progress now.)

Wanna see a video!!!!

Nice to meet you. Thank you for seeing it. I uploaded a video.

Thank You! That looks awesome!
