    Yes, that is right. Very important.

    This is the picture that should give you the answer. Note the timing marks.

    Well, The super glue I got for the magnets is taking forever to dry. and I ended up using 3/4". In the meantime I think what you are suggesting John, is that the timing is a 50% duty cycle. I recall JB saying so in one of the videos. But by the look of the timing magnets and the dwell angle it looks really close to 50%. But I can't say I fully understand what he meant by overlapping...

    this is the quote that sticks in my mind:
    "it's the overlapping of the switching that is important in the dwell angle. This is equivalent to a car distributor and it better be set right."

    Got the new wheel almost finished, Going to go get some glue and materials so it will be a few hours. But I think I am going to like this one much better.

    I will go back and review the posts, I know this is all in there somewhere. And I remember going through it thouroughly. There was some debate as to whether the magnets created a turtle shell looking field or if it was re-aligned like a pie shape. I also recall that it was pretty much just like setting the dwell on a car (I did a lot of that back then...). The timing marks were lines pointing toward the center of rotation. To me that meant that they got finer toward the center and wider to the outside. I would intrepret that as meaning you were able to adjust the duration by moving in and out and the location on relation to the coils by rotating right or left.

    I will go back and review in case I am missing something.

    The hall needs a south pole to switch so the south of the button magnets faces the hall.

    Have another look at JB's timing wheel. Look closely at how close his button magnets are. I think he uses 1" but 1/2" should be fine for a smaller wheel. The timing marks he has on the timing wheel are also a clue.

    Ok, first so we can see this properly lets get the timing rotor right. then we can see the led results properly and go from there. Does that sound ok?

    So they are south facing magnets less that one magnet width apart, correct? Then I will get that made today. But this wheel is only about 22" diameter and only has eight magnets on the rotor. So I thought I would use 1/4" button mags for the timing rotor. Do you think I should perhaps go to 1/2" ?

    Then we should look at John's drawing of the magnets(Flux as some say) around the rotor. The scalar south that is created between those north facing poles and then we can start on the interaction between that and the timing. I am very anxious to see where we are going here John. I am still thinking about the importance of the Delta zeros in between the north facing magnet and the other side of the scalar south.
    It has been my conjecture for some time that like JB said that if you want to affect the magnet you do it through the Delta Zero. So I look forward to getting into all of it.


    Thanks John

    OK, seriously, that's not what I was talking about. I hope I didn't send you on a wild goose chase. But it does have something to do with the scalar south, but the scalar south between the rotor magnets, not the timing wheel magnets.

    Les, I want you to work this out without me giving you the answer so you have to think about it. The question is "why has JB got his timing wheel magnets spaced less than one magnet width apart?"

    You have enough experience with the Monopole SG to work this out as it is the same. The only difference is the way JB is triggering the circuit, the SG uses the trigger wire but the Bedini/Cole circuit uses hall triggering. But both methods are a way to adjust the timing.

    John K.

    P.S. So you can see the timing with the LED just put some black tape around the perimeter and then stick some skinny white strips where the centre of the magnet is. You don't need reflective tape, but it makes it easier to see. Connect the LED so you see the timing marks when the coil is on (hall is on).

    Handbook of Magnetic Phenomena

    Hi

    JB has mentioned about the Handbook of Magnetic Phenomena, by Harry Burke. I have attached a scan of the index pages just to show what the book covers - massive amount!

    Regards

    I remember this was talked about and at one time you had suggested making a super pole south so that is what I did on my other machine. here is a vid I hope it is visible but I used some small rectangular magnets and created a scalar south.

    I'll be looking for some reflective tape tomarrow so maybe we can have some led fun then...

    Timing

    Les,

    Yes, that was the one.

    Have a look at John Bedini's timing wheel on the Ferris wheel again. Notice how close the magnets are together? From the looks of it the magnets are spaced less than one magnet width apart. Why do you think John did this?

    Now compare this to the timing magnets on your wheel.

    Is this where you mentioned it?

    Les,

    Thanks for the vid. I assume the coil switches on just after TDC. It would be good to see on video when the hall switches on and then switches off.

    See my post a couple of pages ago on where the hall should switch off the coil. You need to give it a little more on time.

    So as I understand the rotation or spin as Ed described it, it is happening at several levels. I think I am suggesting only one of those here....
