If your fields are off the meter, and you are trying to do a comparison, simply move the meter back the same distance for both tests.
I have loaded an app on my smart phone for that. Free. Looks like it works. I have not done any quantitative analysis so can't speak of its accuracy. SMF APPS GbR.
Hello greetings
I started the construction of the coil proposed by turion
12 threads 253 23
The first challenge was how I made the count of each coil.
the first was by manual counting, then I put the reel in a winding machine that I built, and I passed the wire to a new reel, and so I knew how many laps each reel had to have
I show you the photos
then go to the construction of the major coil, where first place all the reels in two sections of 6, to be able to manipulate them better
but first mark each thread at the beginning with tape, and also finish it since they had each one, which made it easier for me to verify each thread afterwards
You have the same as Turion now, should be getting big power out
of so many coils, big money machine. Let's hope Dave chines in and
makes sure you don't miss something. You are taking away any
excuse like, "he can't afford to build with the big boys" or that for
some reason "he won't follow direction exactly"
Humm...??
No more excuses.
Right Bi, you are going to except the results?
Can't have it both ways now, bidirectional is out.
I like your winder Alex you did a nice job, only 9 more to go
Thanks BroMikey for commenting, and contributing your experiences also that here in the forum there is proof of your experiences.
If I wait for the tour guide, how well he has been giving so many details and data, and given data and videos of his achievements.
If Turion already achieved something functional, why not replicate it?
how good BroMikey you liked the winding machine, I built it when I made several bedini motors, since first, I manually counted the wire length, manually wound,
until I told myself I am going to build a winder, I started and yawned several ideas, and so it came out, I bought a digital lap counter, I put a 12 volt cd motor on it, I also bought the speed control.
It is a handmade version but very functional, it allows me to make the coils faster.
It can be improved, but as one is more hurried to do the projects, leave one side, make it more decorated, but as the purpose is already fulfilled to ebobinate
Thanks BroMikey, Turion, SkyWatcher for being active in this project, and the other users also for your comments
regards
I tested the multifilar coil at an engine speed of 2400 rpm, obtaining average results, I'm going to get an engine that gives me 2800 rpm to test it with the recommended speed
It's okay to offer material that can be useful to someone else. Let your proposal value.
For now I want to build it with what I have.
In summary it is to make a rotor with a diameter of 10 1/2 ”, and 1 1/2 inches thick, with magnets of 2" x 3/4, 6 magnets per side?
Fortunately I have the proposed magnets
With a coil that I managed to operate with results that you have obtained turion, it would be very satisfactory

Hi all, the double drill chuck motor adapter works nicely, it runs very true.
Going to use this scooter motor now and remove the drill press monstrosity.
Now the motor can easily be swapped for anything with a shaft diameter of 1/2" or less.
And if it needs some pillow block bearings, etc., that can easily be implemented as well, as some are on my shelves.
Also, will be able to use the motor pulse controller I built to run this motor and we can see changes in rotor speed better.
peace love light
I hope you didn't get hit by flying magnets. Did you have an issue or
breakdown? Waiting for parts? I see you stopped working on this one.
Mine is coming slow too. Hope nobody got hurt. When you tighten the
gaps you are in for a big problem using paper wheels.I have
to use metal to feel safe.
Even the best builders here have has an embarrassing moment as they
all under estimated the mechanical engineering aspects. So far not one
practical build has emerged.
One more sample that must be worked with great care and safety, I hope I have no problems with the generator at 2800 rpm, the work is slow because I had to put a 10 mm bar shaft, but it needs a larger diameter, and I have I have to change the bearings and brackets that I have requested, but the generator project goes ahead, it takes time

Yes that is what I use a ten millimeter separate shaft with it's own
two bearing then a coupler. You asked me about my "C" core? I use it
as a self centering arrangement. This way I get equal pull off the same
cylinder magnet on the rotor. Also there is a trading back and forth of
flux since each coil is hit with a north and south polarity at the same
time. Not saying it is better than doing it another way however each
design has it's application. Another benefit is the mechanical setting
of each coil. The large mass of copper sets a good ways away from the
rotors center allowing many coils to fit nicely around the outside.
This may not be as compact because of the large diameter needed yet
is a more narrow width similar to the pancake motor dimension. It is
something I wanted to try. Also I found out shielding magnets cuts
down on the cogging and is needed when magnets are very very close
together like a 24 or 20. Although when there are only 6 magnets
shields can be cut way exposing the cores to a small amount more of
flux. Sometimes every little bit helps.
