    I love a good explosion.

    Excellent!!!!

    thanks doug,

    I did not see them in the files set on thingiverse, maybe I missed something.

    Hey Tom. Yes, they are needed. They serve three purposes. #1 They are the bones of the inner. #2 The are used to wind the outer perimeter coils. #3 They provide the triangle slots for the outer shells. Enough room should be there for a thin layer of dampening material. That black gorilla glue brand duct tape is perfect. Once you cut some strips to put over the triangles in the housing just slide it on.

    Doug,

    the orange brackets are they not needed for the build ?

    I did leave out, unintentionally, that the perimeter windings will be tied together in series to where they will pulse all six magnets poles in the same direction (either push or pull). Power the window coil up first. If, when you power up the ssg coils (perimeter coils), it does not increase in speed, you have hooked it up wrong.

    I've had an inquiry as to how I wound this latest motor. I found that it was easier to just do a video. If anyone needs any further clarification just ask.

    Most cities have a pro skateboard shop. You can get a pack of ABEC-5 bearings for $20. I added three additional files that will give a choice to use 8mm rod with skateboard bearings. These are better than ABEC-7 if you can spend a little more: https://bonesbearings.com/bones-reg-...earings-8-pack

    I made a housing for the motor: https://www.thingiverse.com/thing:2789344 and have some interesting results with coil shorting.

    Hey DMANN,
    First of all Superb work pal!!
    Does the Generator coil (i heard you say you are using 'coil-shorting'using red switch in the video)serve the same purpose as the Aluminium cylinder in Bedini's Spherical Window motor that runs on the Lenz's opposition mode??

    Thanks for the link to Patrick's youtube post. I had forgotten all about it and Dadhav's posts on the subject. I didn't understand what it was when first presented. I still don't really understand what's happening, but it seems to behave like coil shorting?

    I am sure a bunch of us would love to see this at the next conference. if you are coming I will give you a spot at the teslagenx booth to display it if you want!!

    Tom C
    I would like that. I should know by the end of Jan 18' if I can make that happen. I will let you know.

    Do you think the rubber bands ran smoother or is that just my perception loss from the video?
    -Patrick
    Thanks Patrick. The problem with the rubber bands is they get really tacky after about 8 hrs of run time. This is especially a problem the further they are stretched. The chain is noisy. The noise can be reduced with a chain guard if properly designed.

    Your build looks very impressive! Nice work!

    Thanks.

    From your video I assume the voltage measurement on the doubler is from the Bedini - Cole circuit that is running the window motor? And the energizer is not yet hooked up to any load or battery?

    Yes..from the BC circuit. The energizer is not hooked up yet.

    You mentioned in the previous video that the energizer had a trigger winding on each coil. If this is mechanically driven by the window motor, why are you using trigger windings on the mechanically driven bottom unit? Is this for coil shorting? Or maybe over-driving it as an SSG for more out put? Or for switching a controller?

    The separate trigger coils will be to trigger the coils at the right time via multiple ssg circuits as per Patrick/Bolt's method : https://www.youtube.com/watch?v=0leZ...QP5Zv9OtA&t=2s

    I thought the energizer portion of John's 1984 machine was basically a low drag alternator charging a cap through diodes, with a switching controller cap dump to the singular battery.
