Any interest for P51 (T51), P57 or J60 bass pickup schematics?

[jonson]

none whatsoever Brad but then what has Spence's nocturnal habits with sheep got to do with anything baaa him.
As you say this is the place for stuff noboby want's to read.

Who said that Spence's relationship with sheep were nocturnal?

[jonson]

ooops! sorry Kojak didn't mean nocturnal I meant notnormal!!

[David Schwab]

And this has WHAT? to do with the pickups mentioned in this thread?

We were talking about "exact" replicas, that aren't.

Got it.

Gaaawwwwtttttt iiiitttttt!

Now wev'e got all the Gibson crap and what Spence does, when he's not prancing round the house in ladies undies. As Brad said "back to the o rigional post. "Stealth" this is something that if everyone here spent the time and effort they could come up with these drawings etc. "Well done to you for doing so" and as they would not be a Possum style (iv'e got a secret) then you may just as well post them from the start as I feel you wish to and I would say a lot of guys will say thankyou.

[RedHouse]

Maybe he wants us to beg?

[LtKojak]

He most likely got scared... we're used to each other, but for outsiders and/or lurkers this might look like a friggin' freak show, myself included for first!

What was the question again...?

Hooo boy. Looks like I should've triple-checked the exact wording on that first post before actually posting it. Now it looks like I've set myself up for a world of hurt.

The reason I typed the pickup models as T51, P57 and J60 was primarily because of the two differing Precision pickups that are wildly different, yet rare people (on other forums) remember to mention which one it is on the first go. The second reason was, those three bass pickups are the foundation for over half the basses out there, and I figured that anyone who wished to go into the adventure of winding their own pickups could really use templates for them. The end result was a (poorly) constructed nomenclature that, as I see it now, actually created the impression I have the original schematics. So, yes, I pretty much set myself up for this. Now, before everyone decides to throw an appropriately sized stake towards me, please, hear me out. I didn't intend to pull anyone's leg by going all "I have them and you don't, nyah-nyah" because that was I'd dig my own grave before I even became active on the forum. To be honest, I would be very happy to have those designs myself and be able to share them with you - those pickups were the baseline (no pun intended) and would be a great platform to study and improve.

What I do have now is, rather, PDFs and SVGs of technical drawings of the three pickups of that format - non-age-correct, mind, taken from various Fenders, Squiers and other pickups manufacturers - measured with two different vernier calipers (one metric, one metric and imperial), drawn vectorized in Inkscape, inch scale) with dimensions accurate to the second decimal point (possible ħ.001 error due to limited-precision arithmetic). The drawings have all the dimensions annotated as tech-drawings are supposed to, along with a standard, multi-view orthographic projection from top, front and side. No notes about coil wire thickness, the number of winds or the overall pickup thickness as that's something I figure most people would experiment with - I know I will.

The reason I originally produced the tech drawings was so I could print up a template for machining the flatwork - along with the originals, I had several other pole positions and designs to try, some mimicking modern blade designs, some mimicking other pickups from the three (a P57 with Tele-positioned poles? Could work in theory), some being completely custom (non-standard Eko pickups...)

So... any chance of a pardon from you guys, or did I royally plant myself in front of a firing squad? I do intend to hunt down the exact pickups and measure them - I'm pretty sure someone in Croatia has those pickups and is willing to hand them to me for caliper measuring. I'm not giving up on it.

So I still don;'t see a link or a PDF or anything, are you serious or just phishing?

Sorry it's the firing squad. Blindfold on, against the wall and a shout of "FIX BAYONETS"

No Probs Stealth but do post them before Brad gets too humpy.

Uploading to this post: P57, standard pole configuration. Varying gradients denote varying magnet orientations, one possible combination of magnetic and electric polarity listed to the left.

[Stealth]

Adding to the list, here's a dimensioned T51. As the Tele basses are a relatively rare sight, I combined this drawing from several online sketches - should still be fairly accurate. Not sure on the exact polepiece dimensions - something tells me I'm off on those, so please correct me so I can update.

Edit: noticed a typo on one on the mounting holes - should read D (for diameter), not R (for radius). Reupped.

Jazz pickups will be done when they're done (tm). Maybe during my work break tomorrow.

[David King]

Stealth,
The 51T may have used .196" dia magnets, perhaps someone else can confirm?

Both drawings show 1/32" thick upper flatwork. This doesn't jive with anything I've ever seen or heard. I didn't even know forbon came that thin.
My best guess would be both top and bottom flatwork would have been 3/32" thick.

[mkat]

The values for the 57 pb don't look right either. Certainly the top flatwork is too thin.
