The reason for the separate series is that there's a lot that I'd like to discuss about this machine, that requires a large amount of speculation and guesswork.
I'd like the main series to be as fact based as I can get it, so when I know I'm clearly deviating into speculation territory, I'm going to hive the continue reading off into one of these "Fragment" videos.
It doesn't mean that I think the speculated idea is necessarily wrong, just that its more open for discussion.
I'll share my thinking with you, and hopefully you'll have your own thoughts and share them too.

The Antikythera Mechanism (as it has been titled) is believed to be the first computer ever invented since it is the oldest complex calculator created in ancient times. This device is an astronomical calculator that accurately tracks the movements of the sun and moon and predicts eclipses, lunar cycles and seasons.

The principle which allows the Antikythera Mechanism to compute astronomical cycles lies in the function online casino deutschland download no deposit bonus its interlocking gears.
The multiplication and division of whole numbers can be processed with gears of varying tooth counts.
For example, a gear with 20 teeth interlocked with a 10-tooth gear will cause the 10-tooth gear to rotate at twice the speed of the 20-tooth gear.
Furthermore, multiple gears connected on the same axle allows for the creation of gear trains and complex gearing ratios which drive all the pointers on the mechanism.
The diagram below details the gearing configuration of the mechanism where the tooth count of each gear is shown at the joining of its neighbouring gear.
The resulting speed of each pointer is a function of the Solar pointer and therefore every gear train begins with the 64-tooth gear shaded in grey.
Metonic Pointer The Metonic calendar lasts 19 years and so 19 turns of the Solar pointer completes one Metonic cycle.
The Metonic dial itself consists of a spiral of 5 turns and therefore the Metonic pointer is required to rotate 5 times in antikythera mechanism pin and slot Metonic cycle.
A groove following the spiral leads the metonic pointer through to the end of the spiral which would then need to be reset to the original position by the user of the device.
This also represents the number of turns of the Solar pointer, and so becomes the denominator of the gearing ratio.
In addition, the gearing ratio is multiplied by 4 as the Saros pointer requires 4 turns to complete the online casino deutschland download no deposit bonus />As with the Metonic pointer, the Saros pointer would need to be manually reset by the user once it reaches the end of the spiral.
Aligning the perigee and apogee is the line of apsides.
Apollonios of Perga in the third century BC developed a geometric model to explain this varying speed and it involves shifting a antikythera mechanism pin and slot circular orbit off its centre.
The resulting orbit as viewed from the earth would therefore vary in a way which represents the moon's elliptical orbit.
The illustration above shows the four gears in the pin and slot arrangement.
Gear A drives Gear B, which includes a pin fitted through a slot in Gear C, whose centerline green line antikythera mechanism pin and slot shifted slighlty off the centerline of Gear B blue line.
This arrangement causes a uniform rotational speed from Gear B to be converted into a varying speed produced on Gear C.
This varying speed is then carried through to Gear D which carries the resulting motion through to the Moon pointer.
The chart on the right illustrates this varying speed from the lowest speed at the apogee to the highest speed at the perigee.
Now the gearing ratio of the moon pointer is based on the sidereal month and therefore the period of variation from apogee to apogee produced on Gear C, is 1 sidereal month, 27.
This is because the elliptical orbit of the moon itself rotates and therefore the period online casino deutschland download no deposit bonus apogee to apogee lasts slightly longer to accommodate this rotation, known as the precession of the line of apsides.
The way in which the designer of the mechanism would correct this period of variation is a feat of technical ingenuity.
The precession of the line of apsides was observed by Hipparchus of Nicaea in the second century BC to run through a cycle of 8.
The effect of the turntable rotation ,however, is that Gears B article source therefore C would need to rotate a little further in order to complete a full revolution relative to gear D Note the oscillation of the and roll egt slots dice within the slot, it is at its furthest when aligned with Gear D.
This extra rotation corresponds to the difference between the anomalistic and sidereal months.
The new corrected period of variation is now the anomalistic month, 27.
Ultimately, the turntable would have two functions: to make this correction; and also to drive the gear trains of the Saros and Exeligmos pointers.
Predicting an Eclipse In order to predict an eclipse, the user of the mechanism would first turn the crank so that the Metonic pointer is set to the current month of the Metonic calendar.
Observing the lower dial, the user will continue to turn the crank until the Saros pointer enters a segment on the dial containing an eclipse description.
In the image above, the pointer indicates to a segment containing a solar and a lunar eclipse.
The letter Σ, followed by the hour symbol, then θ 9 ; indicates that a lunar eclipse is predicted in hour 9.
Additionally, the inscription below it displays: Η, hour symbol, θ 9 ; which indicates a solar eclipse in hour 9.
The index letter of Ρ with a bar on top refers the user to the description of the eclipse on the periphery of the dial.
Furthermore, the Exeligmos pointer indicates the letter H 8 meaning that 8 hours need to added to the eclipse hour markings accordingly.
To determine the day of the eclipse, the user would then turn the mechanism to its front side and continue turning the crank so that the moon pointer and sun pointer are aligned with the center the alignment of a lunar eclipse.
The sun pointer then determines the date on the Egyptian calendar dial.
Conversely, the day of the solar eclipse is determined when the moon pointer reaches the same position as the sun pointer in relation to the centre the alignment of a solar eclipsewhere the date is also read from the Egyptian calendar dial.

The Antikythera Mechanism Episode 9 - Making The Epicyclic Pin and Slot Source, by Clickspring.
In this video I make what is arguably the most impressive section of the mechanism - the small pin.
The reason for the separate series is that there's a lot that I'd like to discuss about this machine, that requires a large amount of speculation and guesswork.
I'd like the main series to be antikythera mechanism pin and slot fact based as I can get it, so when I know I'm clearly deviating into speculation territory, I'm going to hive the topic off into one of these "Fragment" videos.
It doesn't mean that I think the speculated idea is necessarily wrong, just that its more open for discussion.
I'll share my thinking with you, and hopefully you'll have your own thoughts and share them too.
In this multi part series, I show how more info make a clock from raw stock.
A perfect long term project for your shop.

So what is a Spare Parts video?
Generally it is a shorter video, with content that more info based on a single process, rather than on a completed project.
More than likely it is a sub process that has been broken out from a standard length project video, because to include it would have made the main project video too long.
Mini lathe or Mini mill projects, useful tools and stuff you often can't buy - the best fun comes from tools you make yourself in your own shop.
Clock pillars are an awkward little part to hold and machine, once the tapered and curved sections have been formed.

The pin and slot contraption on the Moon pointer’s gear train is a physical manifestation of this model. The illustration above shows the four gears in the pin and slot arrangement. Gear A drives Gear B, which includes a pin fitted through a slot in Gear C, whose centerline (green line) is shifted slighlty off the centerline of Gear B(blue line).
