I suggest it. Anyone second the motion?
Seriously, though, there are a few Edison overtype dynamos in Greenfield
Village / Henry Ford Museum in Dearborn Michigan. Their curator may have
winding diagrams or other info that would be helpful to you. Maybe you could
try a Google search for H F M / Greenfield Village and see.
For brushes, if you want to use metal stranded brushes as the originals did,
you might try stranded woven copper solder wick - available at any
electronics shop for absorbing excess solder on electronic component joints.
Nice and fine, and frays beautifully.
Good luck, Jeff Dayman Waterloo Ontario Canada
