    SonnyW's pics

    Just a few pics of mine
    Some of my PU's in the Cardboard boxes w/ clear lids The 3 x 2 1/8 x 1 box fits a singlecoil pickup nicely This is a little better shot of the business end of it Sewing machine coil winder setup Magnet to work the reed switch.. I soldered a soft brass wire to a cut off sewing machine needle. To this I attached a magnet by wrapping it with smaller brass wire and coating the whole thing with glue. A single coil magnet fully charged will work. Here's the reed switch. I put inside a plastic tube and hold it with test probe clips for adjustment. I've found that a slight slant works best. Here's the counter. I got it from Fargo Controls for around $30. http://www.fargocontrols.com/specials.html It has a lithium battery that's supposed to last for 10 years. Here's the magnet installed in the needle holder. If you look closely you can see one of the clips holding the reed switch through the plastic. This is the counter assembly. I used a plastic case that originally held one of the old large computer backup tapes, but any kind of a clear plastic would work. I used existing screws on the machine to mount it. You need to be able to see where the magnet is to align the reed switch. Here's my vintage charging magnet. Works great. Came out of a WWII radar transmitter (or so I was told). I like to think it puts some mojo in them just from that. I've had it almost 40 years myself. I closed the gap some. Chewed up a couple of drill bits and a tap doing that. No idea what alloy it is made of. This is about the lowest reading - in the very center of the gap. After more than 60 years, this old magnet still develops over 2000 gauss (surface contact) in a gap configuration. I have no trouble charging Alnico 5's in single coils to over 1000 measured at the surface of each magnet. The meter is a hall effect probe type Alpha Lab DC Gaussmeter Model 1. It is accurate to +/-1% in the 60-85 F temperature range, or +/- 2% in the 30-110 F range. Here's my other magnet charger. A pair of 4x1x1/2 N48 neodymiums mounted in a drill press vise. It has over 5000 gauss in the center of the gap, plenty enough for anything I need. Not much mojo though, just lots of raw magnetic flux. Here is the surface gauss reading. These are STRONG. I forgot to take off my watch when I was putting this together and I was half an hour late to everything for the next two days until I realized what had happened. By the way it was a chore to keep them apart to mount them. I did let them get together and it took all the strength I had to get them back apart. This is my electronics bench and assembly area, taken before the winder came. I have a soldering station, Various handheld meters, Tek2236 scope Tek signal generator, and HP 3580A Spectrum analyser. I have added a notebook pc since this shot was taken. The table to the right is covering my table saw, and has my magnetizer and demagnetizer.
