Lawrence, What diameter of wire do you use? I need to wind precise coils of up to 4000 turns using 38um (approx 1.5 thousands of an inch) diameter copper wire. Up to now I've been using a rather large coilwinding lathe which I've modified for the purpose. The results are reasonable but the winding is difficult and time consuming and I'd dearly like to build something specially for these coils. Do you have plans you could share?

There is a DC motor which I control with a variable power supply that actually rotates the coil, and a servomotor that moves the winding wire back and forth across the face of the coil. It also has a counter so you can wind an exact number of turns. The whole thing is pretty simple, if you can't find one to buy. -- Lawrence Lile Martin Baker Sent by: pic microcontroller discussion list 08/27/02 11:49 AM Please respond to pic microcontroller discussion list To: PICLIST@MITVMA.MIT.EDU cc: Subject: [BUY]: Coil winder Dear Group. In connection with a personal project, I need to find a manual coil winder to help me wind 35-50 small inductors. I would love to buy an old Morris or other Coil winder that will allow me to wind close and basket coils. If anyone has one of these sitting around, and would be willing to part with it, please let me know. thanks in Advance and very best regards, Martin -- http://www.piclist.com hint: The PICList is archived three different ways.
