Core Length: 28
Core Width: 10
Core Height: 9

He said in post #1 that the mags are 20mm tall, and the flatwork is 3mm thick - so core height is ~14 mm.

Ehm.. sorry.
Really, I beg your pardon: mags are 16mm tall.
I only have metric conversion and english language as an excuse.

[EtLa]

9 mm core height came from Biarnel.

The bobbins are 9mm tall. I mean, the room for the windings is 9mm. I made that flatwork way too thick and they sucked up the 15mm tall mags

Do you have a web link (specs) of your counter?

Now I try to explain why I don't think its counter's fault.

I wound a 2 string coil, not thinking to how many turns, until I had 3.50kOhm.
Well it was SO BIG that it didn't fit inside a Jazz bass cover.
(remember, the coil in the picture fits a P-bass cover, wich is way larger)
That 3.5kOhm coil was 13000 turns.
If the counter was bugged, let's say, it reads 13000 but we have 8000, ok? that's quite a bug!
But... a coil with 8000 turns SHOULD fit in a Jazz Bass cover.

The link doesn't work.

Did you check the accuracy of your multimeter with a resistor?

[Biarnel]

Yep.
I replaced it with a screenshot of the page.

Did you check the accuracy of your multimeter with a resistor?

Yes I did.
And try 3 different multimeter.
The multimeter was right.

now, if:
the multimeter is ok
the counter is ok
the wire is AWG42
...where's the bug??

[Dave Kerr]

Gotta be an exchange rate issue - did you recalibrate from lira to euros?

Here's why I don't understand what you are saying... a Jazzbass pickup has about 9,000 turns of wire on it. So 9,000 turns of 42 awg will indeed fit into a Jazzbass cover, and give you about 8K.

A Gibson Sidewider from an EB-0 had about 12,000 turns per coil. Those are BIG bobbins.

There is absolutely no way you can wind 13,000 turns of 42 awg on any size bobbin and get 3,500 Ohms. I get about that on 4,000 turns on a Jazzbass size bobbin.

Either your winder is not set up to count each rotation, or your meter is off.

[EtLa]

max number of strokes 500 per minute

the max number of strokes 500 per minute is pretty low for a winder.

[Biarnel]

I tried the multimeter over 40cm of my wire, and I read 2.9 Ohm.
I expected 3.6 Ohm.



Anyway, the wire (with coating) is 0.0028", which is right for AWG42.. and the guy who sold it keep saying the wire is AWG42.

I' sure your magnet wire is ok

Try this... to prevent short, put nail lacquer on the magnet wire between the eyelet and the first magnet that the wire meet, let it dry and slowly wind a pickup at ~400 rpm

[Biarnel]

Again, if there was a short I would have some reading between the mag and the wire, and it's not the case.

I'm not talking about the magnet short but short between the first wound and later wound

That's what I was thinking also.

...A short in -four- coils? Always in the same exact position? ...unlikely..
