A washer with a hole in the center might change the shape of the magnetic field, especially if it is insulated from the core of the coil by the insulation around the windings on the wire of the coil.  (snipped)

I was wondering about the washers...RomeroUK said in one post I think that they were common 'iron' washers, but is that right? Or was he speaking somewhat generically? Not sure what the metal is in the ones that Home Depot and other places sell...would not want to use the wrong type since that whole external magnet thing is said to be key.

@thread  I don't know if the coil shorting is a correct vector

Would be nice if RomeroUK would come back here and for any given speculation that *is correct* (posted by say Hartiberlin to keep the focus clearer), and reply simply: "Sorry, but I am already in a lot of .... I don't need any more!" 

And if the speculation is *wrong*: "I am still in a lot of .... but I feel better now." 

@duff, thanks for the reply, saw the note on the diodes. Affordable options on the rectifiers are 100V @2A, 200V @4A or 600V @4A.

Not sure which would be closest to the originals he used, am guessing the 200v @4A would survive a longer time.

for some reason, i can hear that 'Queen' song playing quietly in the background:  "...And another one gone and another one gone. Another one bites the dust..."

BTW   has anyone seen Penno recently, since May 14:  "This is bigger than you know. A few more tests, then I will confirm" ?

According to the forum stats Penno is still on forum:

I hope that toranarod doesn't go quiet to.

I was thinking the same thing I hope they will be back soon.
I'm building a mini dynamo just to do some experimenting, I hope this rotor will hold
