Hi All;
I have documented a few coils, two from my Radio and two unknown coils.. One of the things you can do, to get a fairly good estimate of the number of turns, First, Is to measure the length of the coil of wire.. Then measure a standard length of the coil for a certain number of turns or for a short length like 1/8 Inch or 1/4 inch and count the number of turns in that spacing.. Take the short length and see how many of them will fit into the total length of your coil.. And multiply to get the total number of spaces and then how many turns you had in the spaces..
So if You had 10 turns per 1/4 inch and your coil length is 1 and 13/16th inches long.. So one inch is four quarters and each quarter is 10 turns, so you have 40 turns, plus 30 turns and about 2 and 1/2 more turns..
It might not be absolute, but it should get you in the Ball Park of about how many turns you are looking at.. It is easier than couning the whole length and loosing track..
THANK YOU Marty
