RE: [TCML] Oregon Coilers?
Hi Rick.
I am in Salem, Oregon, and would like to get something like this going as well.
I wind coils in minutes with a large ac motor I acquired some time ago, which is hooked up to a variac. The motor has a 6" flywheel on the axle.
I just attach the coil former to the flywheel with a generous amount of packing tape to hold it solid. I have the magnet wire on a spool at an initial height between where I plan to make the first turn and the middle of the coil. I turn up the ac until there is a pretty steady pull from the motor, and I use two fingers to pinch the wire to regulate the speed, and use another finger to hold the wire up tightly against the previous turn. I move the spool up higher twice through out the winding, which makes it easier to keep the wire in line with where it is wrapping...too low and it tends to wind over itself, too high and it tends to put space between the winding. Stopping to place tape over the turns you've completed every few inches keeps the turns tight.
I can wrap 20" of magnet wire on a 4.5" coil form in about 15 minutes.
I'd be glad to show you my setup Rick, if you are interested.
Won't work for huge coil forms, but works great for the smaller ones.
I feel your pain. I hand wrapped my first coil on a black abs pipe, and of course it didn't work at all, so frustration motivated me to find a better way.
We need a group here...Northwest Tesla Builders Coalition...or something along those line.
What do you think Mr. Karr?

Subject: [TCML] Oregon Coilers?
Fellow Coilers,
I just re-subscribed to the list after a hiatus of several years and am wondering if there are some coil builders in the Portland, Oregon area who are interested in getting together. (or anywhere in the NW for that matter)
My vocational background in neon sign fabrication interested me in high voltage apparatus, which prompted me to join the TCBA many years ago. I certainly enjoyed reading the newsletters, but never got around to actually starting a project because some elements of the design/construction remained cryptic to me despite reading books like Pringle's guide.
Now I have begun to move forward with a small SGTC (12 inches of winding length of 30 gauge wire wrapped on a 2.5 inch PVC form). After around eight hours of tedious hand winding, I am motivated to assemble a winding lathe of some sort for future secondaries.
Thanks in advance for any advice or suggestions...
Regards,
Rick
