I just rewound a plastic bobbin strat pickup and with good tension and little scatter I could not get more than 5k with #42 single build poly. I used #43 instead because I wanted about 7k but doesn't that seem strange that I could only achieve 5k with #42 ?

Yes, it's odd. I can get 7k with 42 (overstuffed)

Well if you can get 7k on a plastic bobbin I should be able to at least get 6 or 6k+. I guess I could have shorted it at the same spot 2 times in a row but I'm usually not that lucky, or is it unlucky.

How many turns did you put on there?

The other question would be is it a standard height bobbin? Some are not.

I set my down counter to 9000 and filled the bobbin with 42 but I've already forgotten the turn count. I was thinking 7000+, but the the reading was definately around 5k. I didn't know there was more than one height plastic bobbin, that would make a difference. I ended up with 7.6k of #43. The guitar is gone so I can't measure it but if it comes in again I'll measure it.

Are you using a lot of scatter, this will cause the coil to be very big and bulky due to the wire sitting on top of the previous layer causing a lower DCR rather than having some of the layers fall between each other or having the layers line up closer to each turn. Also how much tension are you using?

Well I thought I was using a small amount of scatter a good amount of tension. My scatter is set by several cams I had made, winder based on Jason Lollar's book. I have never had this trouble before and even checked my meter and counter. Maybe it's like SK said, a non standard bobbin. BTW, why would Fender use a smaller bobbin? The guitar was a sort of a frankenstein strat, body and neck looked a little odd even though it had a Fender decal but the pickups looked to be a AM Strat with plastic bobbins and bridge pickup with the 2 screws that screw in from the bottom.

Some of the cheaper ones where they used solid ceramic bars underneath were a little shorter (I believe) to make some room for the height of the magnets.

Well that means they were standard height because they had alnico slugs. This can only mean one thing, I'm an idiot.:D
