      It will never happen. He was silenced by the clockmaker's guild for revealing closely guarded secrets passed down over the centuries to apprentices who proved themselves worthy of the sacred trust. The secrecy helps to protect the earnings of the guild members. Honestly, how many poor clockmakers do YOU know? I rest my case.

  • @ReactanceIsFutile
    @ReactanceIsFutile 7 ปีที่แล้ว +11

    Great video-- thank you for sharing. I do have one thought to consider: You're too focused on using the divider to 'guess' your way to the proper tooth division distance. Time is money. They were well aware of PI, and the relationship of circumference, and diameter by that time.
    Therefore, the most likely solution to allow them to determine caliper width for marking, was a very simple, one-pass process:
    I've explained it here:
    They were exactly aware of how many turns of the adjusting knob it took on their marking caliper to close or spread the caliper for a specific, common distance in clock work.
    Once the circumference is known, and the width of the division is known, all that must be done is that the caliper adjusting knob be brought to zero (legs closed), then turned the appropriate number of times (to open them). Caliper is now the proper dimension for tooth distance, and the wheel can be marked. One pass, no guesswork. Engineering.
    Remember-- they did this for centuries-- the stumbling only lasted a few years.

  • @gadget348
    @gadget348 7 ปีที่แล้ว +2

    Now for the time saving maths, just after you inscribe the main radius (before you saw anything) take the radius and mutliply it by two then multiply the result by pi (3.14159) e.g. R=12mm, R*2*pi = 75.4mm. Now devide the answer by the number of teeth e.g. 75.4 / 31 gets 2.42mm. Now set your compas to 2.42mm and inscribe a semi circle to the circumference, from the centre of that circle mark a point on the circumference and from there draw another semi circle. Mark half the disc this way clockwise, then start back from the top and do the same counter clockwise (this is to reduce the cumulative error) and your done. If you do this for a larger wheel you will see that these circles intersect a two points, draw a line linking these two points to the outer circumference these intersection points is the marks you are after!

    If I were to become a wheel cutter I would be tempted to make a much larger disc with a centre spigot. Each disc could be marked out very much more accurately because of its greater circumference and a straight edge used to transfer the lines to the wheel blank mounted on the spigot. Very low tech and much easier especially with small wheels. Once made the pre marked master discs would save considerable time. I know this video is a demonstration of dividing but I can't help wishing that you had mentioned how it could have been done without precision drilled index plates.

    Have you seen how clickspring did the deviding on his latest project? Basically he made the circle to be devided much larger then the gear to be cut, and the projected the spacing back onto the gear, thus making the deviding a lot easyer and more precise, still using only a pair of deviders like you did here. cheers.

    • @SlaveToMyStomach
      @SlaveToMyStomach 7 ปีที่แล้ว +4

      That was my thought. Why not start with a large wheel, say the size of a wagon wheel, and cut, by hand, a large number of teeth, e.g. 360. These can be marked out using the same method of walking the divider along the edge. Now a much smaller blank can be placed at the center of the large wheel which can be rotated an approprite number of teeth for the gear to be cut. Any error in the layout of the large wheel is reduced substantuaily in the smaller gear.

    • @cymeriandesigns
      @cymeriandesigns 7 ปีที่แล้ว +2

      It's not clear when the dividing plate came about, but the Antikythera mechanism that Clickspring is reproducing is 2000 years old and contains some pretty small gears with a multitude and unusual numbers of teeth. Something along the lines of a dividing plate seems like a necessity, at least in its case.

    I watched this sometime back and since I have seen a quite a simple method for division and it seems more accurate.
    The gear is let’s say 2” wide. The divisions were found from using a compass placed in the center of the gear, and then the compass drew a corresponding circle of let’s say 12” around the outside of the same circle. This allows for the dividing now on a much larger scale. The radial lines are drawn through the center of the gear to the outside of the 12” circle. This increases the accuracy by a large factor and makes it far easier. The result is the same. This would be even easier the smaller the gear. Your thoughts?

    Nice video. When using with the dividers and changing the distance, if you use fresh ink between changing the scratch marks you'll be able to keep better track of the marks you just made over the old one. I use the fresh ink method all the time when marking parts for machining then changing my mind about where to cut.
    Thanks for the history lesson and the interesting knowledge.

  •  7 ปีที่แล้ว +1

    Kosmos, thanks for this video! I just want to ask to give us the other parts! It's too bad there is no part after months!
    About on how to divide the wheel: since everybody is saying what they think, here are my thoughts: I'm not sure if there weren't people who did this but I would simply get the circumference size by doing 2 times pi times radius and divided properly by the number of teethes plus one to get the section size for the desired number of teethes. And them, using a ruler (I'm not sure if it was available a somewhat precise ruler - surely not in centimeters), I could get the proper arc for the tool used to mark the blank disc just for the sake of the video.

  • @mayflowerlash11
    @mayflowerlash11 7 ปีที่แล้ว

    Very interesting and impressive video. When you adjusted the dividers to make 31 rather than 32 divisions on the circumference, manually!!!!! I thought "Holy C@#p", this guy is good. I thought a geometric technique must have been used, not trial and error as you did. Perhaps geometric techniques would have been used to make the dividing plate which is the template from which many accurate wheels could be made. This is a very good explanation of how clock wheels were made at the earliest time. I like your presentation method. Slow enough for students to take in the significance of each comment. And like many of the other comments below, I too want to see PART 2. Stop teasing us. Finally, I think this explains how the Antikythera mechanism was made in ancient greek times. Even so, that device inspires awe in anybody who can appreciate how far in advance of European clock maker it's creator was. Thanks again for this video, now please give us your promised PART 2.

    They might have used something like a straight edge knurling wheel to get the position of teeth.
    A knurling tool if slightly out , is pressed in slightly more and eventually it meshes perfectly. If the cuts arent deep enough it still gives the positions to file down.

    so, what's new about any of that? How else would you divide a circle?

    The Antikythera mechanism how was that made ??

  • @dokbob5795
    @dokbob5795 7 ปีที่แล้ว

    With the diameter of the inner circle known and hence its circumference. Would it not have been easier to strike off the test lengths on a straight piece of brass?

    The question is, how they cut all the way through, if the blank was sitting straight on top of dividing plate, without damaging it? I have seen different device,very old,which had a 1 tooth cutter on rotating wheel and worked somewhat like a shaper. Dividing plate was NOT under the blank, but on side and the "cutting table" , on which the blank sat, was movable just a little bit...the amount equal to cut tooth depth plus little bit more...on the screw. So the first pass all around was barely cutting, then small adjustment of the table with screw closer to cutting tool and again one more time around, but little bit deeper, and again and again until it was all finished. Cannot figure out how this one cut.....

      I believe the piece to be cut sits at the top of the spindle. The highest part of the machine looks like a clamp to hold the gear in place using the pin with the conical end attached to it. Zooming to full screen, I think there is actually a small gear still clamped in place. I see what looks like a cutting wheel lined up next to it.
