Hi. I am just learning to wind my own pickups and I have been practicing with 42awg alnico5 mag. This is my issue, 1 bridge pickup has 5100 wraps on each bobbin and is at 7.32 the 2nd bridge pickup has 5150 windings each bobbin and is at 8.16. I am trying to hit 8.10.. So I am wondering if I have to much tension on the wire... any thoughts
