Duct tape it together!

Don't tempt me!! I think I have longer screws but I think i want to go with stainless steel. Those I do not have in my parts bin.

John,

No big deal! I'm right a very small fraction of the time!! I'm told the green bobbin pups are just the two slabs , top and bottom, and no inner core. The pole pieces just determine how wide the two slabs are. From what I have heard, the pup re-winders hate re winding these because of the lack of center core. It really would have been easy to make a thinner bobbin but I did not want to screw with either of these very rare and desirable pups. The one on my horsie measures 6.31 Ohms.

Sepp

Sepp, I believe you mean 6.31k ohms, or 6,310 ohms.

Oh for the record. The green bobbin, slotted pole piece bobbin on the 67 horseshoe pup is the exact same height as the non horseshoe green bobbin with slotted pole pieces. Exact same! Like I speculated, RIC just had wider open shoes made to accommodate the taller bobbin. My rough measurement of Mark Walkers bobbin was spot on. There was no shorter bobbin made in 1968 for use with the horseshoe pup. Earlier raised lip bobbins, yes. 1968, no.

Well I'll be.... Right you are. Gee this is embarrassing. Well looking at the two side by side in my own collection I concur with you. Optical illusions, though I could swear I've seen green bobbins that are short like a lipped one.
That certainly explains the distinctly different tones between the lipped and green ones.

I would think that winding over screw threads could be nerve wracking to say the least. For some reason, I thought that there was a wrap of rubber tape over the screws prior to winding. In a moment of idiocy I unscrewed an inner pole out and it was goopy with adhesive.Given the number of pickups killed by adjusting the screws this might not be true for all of them. For the record, the pick still worked when I sold the bass years ago.
If you want to see a true disaster on the level of an F5, look at the innards of a lipped bobbin; makes the screw threads on a greenie look as smooth as silk.

John,

Yes, 6.31 k Ohms.

That's the thread I was trying to find. Thanks Steve.
