Pretty cool setup there. I use a hand drill myself (4to1), but I guide it by hand and just put the spool of wire on the floor below. I usually just count 50 turns, check for tangles, another 50, then make a tally. Repeat 20 times and you have roughly 8000 turns. Usually takes under 30 minutes to wind one. I figure as I make maybe 4 in a month, I'm not that bothered about setting up a rev counter. I also just buy alnico 5 magnets from eBay, cheap enough. Enjoy!

Well I like it. Thank you for the post.

Also remember to coat the nails with Verathane to insulate the nails from the wire and then pot it in a wax paraffin mix. Basically this how a Gibson P90 is made.  And you can change out or add to the magnets to see if it changes the tone.

Thanks!

I wrapped the nails with Teflon tape to insulate the nails.  ...just finished up 100 turns... or 350 turns on the pickup.  Will work on more turns when I get back from camping.

I don't plan to do the wax thing.  I've just been wrapping the finished pickup with Teflon tape again.  Sometimes I just leave it bare wire.

Had used three round rare earth magnets on previous PUs.  This will be the first one with a bar magnet (thanks to China).

I'm considering wrapping one of the bar magnets and laying it flat on the surface of the guitar...  Would have to finish it somehow to prevent damage.

See how you get on without potting, but if you find the pickups very noisy, give it a go. It's not hard.

The few I've made so far sound good... a little dirty sounding like I like.  :)

I've found that expecting the spool of wire to turn on an axle can be a big ask, when you come to like it you'll want to buy bigger spools, and the breaks come from there, cos the spool is too heavy to turn freely...

Try turning the spool on its side on the floor beneath where you're winding..

This is what I was getting at. Thanks Kid. They seem to feed very easily from the top, whereas if you're trying to rotate a 250-500g spool of wire by pulling one strand as thin as a human hair, at speed... snap!

You can see on the jig where I originally had the spool on its side, but there was too much friction  so I put it onto a dowel.  I expect a larger spool to have even more friction and thought about some bearings.  Letting the wire pull off from the floor is a good idea, but does it cause the wire to twist too much?

If you get a cheap calculator, you just have to find one that does a repeat:  i.e. hit +1, = , =, =, =  it should increment by 1 each time you hit the "=" key.   On your handle, hook up a piece of music wire so every revolution it hits that key...

Cheap and easy...

You can do this even easier with a $2 eBay pedometer and a 35c reed switch ;)
