I wonderin how large of a prop it would take to overcome the magnetic field created by a 12v car alternater at speed. Also, dose a simple modificatin exist (short of rewinding the coils) to fix this?

youd get more answers about that sort of thing from this website www.dutchforce.com
its an electronics forum, its not dutch, it just has dutch in the site name because one of the admins has dutch in his name.

Thanks' makourain,

               I'll take a look.
Looking around it seems that all electric motors can be used. I have a few old real to real tape decks,each has two.Are they suitable?

Try a google search for "tape drive windmill", will pull up heaps of windmills built using tape drive motors.

nah the motor is fine as it is.
stick a hub on the front of the motor which u can attach your blades to.
you are ready to go.
