    Hi Guy! I'm on a project of building my first tele and beside the neck, I'd like to make every parts I can, including the pickups. So, I found they sell pickup parts on stewmac but I was wondering if you guys knew other places to look for magnets and stuff?

    Thanks!

    Thank Ed Hawley too - he put me on to them. They offer the whole range of AlNiCo blends and are a bit cheaper than Stew Mac. Only problem for me is their enormous shipping charge to Aus. Probably okay to Canadia.

    Nick, the descriptions on Mojo Tone's site says that most of those rod magnets are not magnetized. So how do you magnetize them?

    Seymour Duncan has this big, scary looking machine in their shop to do this, but it also looks like a sure fire way to create sterile luthiers.

    You can use those magnets and do it by yourself

    Jim, the guitar repair magnets will magnetize the alnico rods? Will they do it to the correct Gauss?

    They are supposed to fully charge the rods. To do this you have to pass the pickup between 2 magnets a couple of time. They gives all the detail of the procedure on the stewmac website.

    I'm no magneterologist or nothin', but I think if you use a super-duper magnet pair like those neodymium suckers with some serious gauss-idge, they'll juice the pickup poles to their maximum Gauss-ness.

    Sorry for all those technical terms. ;) :lol:

    I have no magnetometer - someone who does have one could chime in and tell us if they get the assumed gauss readings after charging their pickup poles...

    ...pickup manufacturers probably might measure their magnet inductive-ness.

    I wish I could find a reasonably cheap gauss meter, and I wish I knew what gauss the rods should be gaussed to.

    Actually, I guess that If I had a gauss meter I could measure one.

    I know that the magnetization is one of the ways that pickup manufacturers can tweak the tone of their pickups.

    eryque: If you're any good with electronics, you can build a gauss meter...relatively cheap, as long as you have a reference you are trying to achieve (so you can forgo the expense of a calibrated Hall effect device)

    Some information is here:

    Whoa! That's awesome! I can even understand most of that :)

    I just use a set of science kit like magnets that I got at a surplus store, just need a north and south. polarity only really matters with humbuckers as on singles fender used both over the years .

    K&J magnetics sells neodymium magnets for way less than Stewmac. I super glued a set from them to a "C" clamp and marked the polarity with a sharpie. A Couple of passes and your pups are magnetized or re-magnetizedor polarity flipped for RW/RP. It is pretty fool proof. Using the "C" clamp, you can easily adjust the magnet distance to compensate for your bobbin height.
