Nah, Just run your fingernail along the wire and straighten it out, then you'll need to learn how to use your palms to "twist" large sections of wire to take the slack out. It takes a couple of hours but that coil is salvageable. This also happens when it gets fairly cold outside and the form contracts. I've been through this many times, it's a pain, but you don't really have to start over.
I knew it was salvageable, since none of the wires were broke and it didn't look like it damaged the enamel too much, but I was a bit hasty and I unwound the coil to about 10 turns before the offending spot, but now the wires are ticker and I have some of that excess urethane and is making it difficult to wind it back and have it look good and still have 1000+ turns, so now I'm trying to figure out a way I can strip the urethane off but not harm the enamel, which I'm starting to think is either going to be difficult or impossible, since a good paint thinner would probably strip both off, using a knife or something also has the risk of stripping off the enamel, and heating the urethane off would burn off the enamel also, and just using my fingernails doesn't do a good enough job.

Found this lil guy in my room this morning.
Couldn't get a better close up, so i kept looking for him throughout the day hoping for a better shot. Got my chance early in the evening when i found him caught in another spider's web

Long ago I got 8 capacitors from BGMICRO for $40. $5 a capacitor. Then i saw these capacitors on ebay, 16 for $100. Less than 5 dollars a capacitor, and they have holders. I couldn't let a good price down so I bought them. They are a lot better shape than my BG micro capacitors, Nice and clean blue coating, not a single dent. This bank came in series, hooked for 900V 9600uF, or 3888 Joules. Not bad for $100 + $20 shipping. It came here as 42 pounds, UPS.
So here's pictures of the bank and other future projects. Quad MOT stack, 3 grey caps for a coilgun, 4 blues for exploding stuff, electrothermalgun, and the big bank...Still planning =D SCR in the picture is 1200V 650A. Diode for anti-parallel voltage spikes is 600V 320A.
Anyone else see this 16 pack on ebay?
Random drawing i did at school, during free time. 2-5 mins a day, for maybe 3 days.
