I did not draw this one. I am however trained to draw in CAD and have done so for a living doing AV design. It has been a handy skill for making guitars because I can work out dimensions and assembly virtually first before building. I also spent years as a tech on a bench doing electronic repairs (before people began just throwing stuff away). You live long enough, you end up doing lots of things like even building instruments and pickups.
I modified a cheap pickup, apparently from US, the single magnet inside was short and weak, so i replaced it with small very strong magnets from a kids game, magnatronics I think, plastic with magnet each end that connect to ball bearings to make constructions, I doubled up the magnets and put 8 pairs in the PUP, just realised its too powerful, have lowered PUP as far as I can, so now gonna remove 3 pairs and separate them. I 'll let you know the results. The way I could tell is that the strings sound wierd with the PUP in, but OK without!!!
I have made many types of things, but but wiring/electronics have always been difficult for me. The idea of winding my own pickup, much less it working.scares the begeezus out of me.
Toadie, there was a seperate discussion on this somewhere recently, but to the best of my knowledge no one has confirmed or provided results of their experiments. I have a few wheel speed sensors, a cam position sensor and some odds and ends I intend to wire up and do some testing with, but getting to that is a ways off at this point.
On the subject of building/winding your own: Any of you that have experience/knowledge with this care to explain the "scatter" winding term/theory I see from time to time? I have some experience with custom/hand winding some other unrelated electrical/electromagnet components, and the thought is that carefully laid parallel winds are most efficient as crossed wires may tend to "cancel" each other out to some degree. So I am curious as to the thinking with mag pup winding.
I'm slowly collecting part for my first guitar which I don't plan to be made of wood or have any conventional guitar parts on it (including pick-ups, strings & neck), and have "acquired" three ABS sensors from a Mazda Roadster (which work on the same principle as magnetic pick-ups).
Yeah there were a few more modern machines there as well but for the reasons you mentioned, I had my eye on this one. Then when I saw yours I realized I should just pull the trigger on it. I removed a few more things from it after posting but didn't get a chance to get back to it this weekend. After you take a few things off, you get led deeper in and find new things to remove, and I'll continue until I have the motor running the handwheel. Thanks for the tip on the oiling process; i'll be picking some of that up, soon. Here's the pic to show you the end of it. It's setup really well to be modded to a winder.
i removed everything but the main shaft and the pulley. you will need to oil (with sewing machine oil) the shaft and motor fairly frequently, especially once it's running much faster. that sewing bobbin winder that idles off of the pulley needs to go. anything that has to due with sewing really. post of photo of the end of the pulley and how it mounds. there should be a screw that holds a knurled knob from moving once it is hand tight. this machine should be perfect for winding pickups. good find. more modern machines are a lot harder to dismantle and still have them work.
Also I've started the process and did loosen the motor to see how it spins with no belt and it revs up nicely - the cam is pretty gummy inside and bogs it down. I just pulled a few things off to get started. I currently have more important things to tend to - learning the art of the Mint Julep, refining my technique, and imbibing them until my frustration with humidity drowns in them, while enjoying the company of others.
Just picked one of these up. Plugged in at first it is slow and will indeed need to be gutted. Care to share any info on how extensive the gutting process is for one these before I get in, or tips, Sack?

8000 winds by hand is painfull and near impossible, I tried it and even I lost count at 5903 or was it 5908?
and then I found the pickup was tangeled way back and i hadnt noticed.
(it worked but was quiet as ususal.. wax potted it an all... though ugly)
there is a great book on pickups vailable at amazon with a picture of a 50's truck on it full of pups.. a great read
also the back of the semore duncan catalogue is usefull on the diffrent sounds etc and windings etc.
It is an art form for very patient and very careful people....mind you my telepone cable and lollypop one worked ..just!

My stuff is pretty boring. Like this drawing.

Would it be worth trying to use these as pickups?
