Romero said that others needed more capacitance in their coils. One way is bifi. I posted that after romero's post and he verified that fact. True or not, I cannot say.

Are your coils easily removable as to change up later?  If so, good.

Some suggest that he may have had shorted coils involved as his experiments just before this motor were involved with shorting coils and increased distance from the rotor magnets.

So if after testing with what you have, try a couple turns of shorted windings on top of the existing coils to see what happens. With only few turns of shorted windings the drag should not be much as compared to shorting the larger winding with a magnet pass, but might influence the larger winding in a good way.

Just some things that I remember from back then. ;]

Good luck. Will be watching. ;]

Hi Scorch
It looks good so far -
It is good idea to have multifilar winds since you can run them in paralell or series later on to adjust your impedance (and "capacitance" of coil) and also the voltage out and amps out from your coils after you get it going......
Also it looks like the bolts sticking out the back of your stator plate are going to get in the way of the where the backing magnets will position best. 
You will probably have to use ring-type magnets for your backing magnets that go around those bolts so they sit right behind the stator cores....this is what I had to do in my first Romeor-variant project since I already had a lot of litz coils wound from earlier project and they were mounted with bolt and nut  through stator plate.....
However, what I learned was right behind the stator cores might not be at all where those backing magnets should be postiioned - maybe they should be 10mm or 2mm this way or that way so that you get the "speed up under loaded coils" condition happening because of how the backing-rmatnets react to the rotor magnets at certain rotor-speeds,
and strengths, (via how high of a stack of backing magnets)
and also the distance between the rotor magnets and backing magnets,
plus the distance between backing magnets stator cores,
plus finally the distance between rotor magnets and stator cores.... so there is quite a few variables right there eh  - forgot to mention a few others you will find when you start testing
....so anyways its good idea in my book to have perfecly flat surface on the back of  your stator plate so the backimg magnets can go anywhere they need to go....
anyways good luck have some fun with it,...

Does anybody have the scope shot of the drive coil ? (romero's)

Guys, I would like to play around with N-N--S-S magnets on rotor but have no time nor tools to build it. If anyone could do this build for me, please PM. We can discuss about details later then.

Cheers!

P.S. it might sound off topic but E. Leedskalnin flywheel is very related to original Muller build...

Just another build photo.
Finished all the main mechanical stuff today including the stator plates, rotor, and coil mounting.

Nice  setup!
