Re: 2 axis coil winder help needed

Hello,

Have you seen vince Gingerys book on building a coil winder?
Lindsaybks.com has it...

Is there a reason you really NEED cnc for this? (cuz making accurate
coils has been pretty effectively done for decades without cnc)

As long as you're winding "full" layers, all you need is a motor, a
click counter (few bucks surplus; or could use a hall effect device
and electronic counter, which could then speed and slow the motor
with a pic micro); and some easily constructed wire "followers" to
help change dirs at each end. You can even wind narrower coils on top
of wider base coils with this structly mechanical (and CHEAP!) setup..

I love cnc, but sometimes it is overkill...

Hope this helps,

Ballendo
