You'd probably have to pile on a bunch more winds to get a decent resistance to the coil. 30 AWG is about 10 ft / ohm, while 37 AWG (typical pup gauge) is about 2 ft / ohm. Another chart indicates a pound of 30 AWG is 340 ohms, while a pound of 37 gauge is over 8000 ohms. A little bit thicker wire yields a lot less impedance. Your pound won't go very far at that rate. But tryin' won't cost much other than time, so it's worth a shot to see what you come up with. Most likely sound thin, would be a bit hotter with a rare earth magnet (old hard drive neodymium, if you have one handy).
Old hard drive ??? As in how old ?? Cause I have some that go back to the 80's...
Hmmm, Now I have an idea.....Steel rod with the magnets on the bottom of the pup!!!!
That's a fairly typical arrangement - either one magnet at the bottom, with iron pole pieces coming up thru the coil, or individual magnet bars for each string (all in the same polarity). The age of the hard drive is less important than the strength of the magnet - if there's a danger of (painfully) pinching your fingers between the magnet and a piece of iron, you're on the right track. Use caution with some of those rascals - those suckers that are positioned across from each other (with the head positioning coil between them) will try to get together, and you don't want to have your finger there when they do.
now to get em done to see what it sounds like!
You will likely find that it suffers from microphonic feedback. This can be remedied by soaking in melted paraffin wax to fix the windings in place. Try it without first, so you can establish a baseline. It can always be waxed later. Also, there may be better ways to fix the windings - check with Ted to see what he uses on his.
Cool! What did you end up with for a magnet? And by poly, do you mean a polyurethane varnish? And if so, what kind?
