Re: [EVDL] 9" adv Aluminum feild coil housing ?

Thanks for your reply Jim,
Seeing how you need the ferrous material for the
motor to work properly. How about if you make Ball end
mill channels, say half the thickness in depth along
the length of the motor circumference ? (o.d) This way
your just remove access material but still have the
original body ?
Yes you could remove to much and weaken the housing,
but you and other motor builders do remove material
from the outside and don't appear to have problems ?
I don't know.....just ideas. I have a road racing
background, so this should explain my weight
obsession.
To date I have removed well over 1,400lbs from my
Porsche already and have my eye on another 150-200.
Thanks,
Jeff McCabe
