Just wanted to tell you how much I've been enjoying all your guitar making threads. Terrific stuff!

lightweight..
i'm convinced that that's where HALF the mojo is.....
 
 
 
and the reasons why the wood is lightweight to begin with..
if the gods and stars align, the wood fibers will align.
 
then all is right in the universe.

henkejs- sure glad you're enjoying it and appreciate you letting me know.
 
Bat -
Man I hope the stars align...I sure hope this thing is worth playing some day.
 
I know each piece of tonewood in a build has a frequency and it will absorb those frequencies.
Now trying to predict the best frequency for the pieces in a build is way above my head.
It's really all a guess for me...until I play it. Then I'll plug it in and see if I got close with the pups...if not the cool
thing is that I don't have to spend big bucks to make changes.
I know I grew up playing a heavy LP and it had great tones...so I just don't know.
 
I decided to start on the pups since I'm on hold waiting on tools and materials.
So here's how I get started- right or wrong lol.
I'm building these to pre '70's specs.
 
 
Notice the eyes on the bobbin bottom on right.
The one on the left is after I set them.

I have a little anvil and tool to assure they are set correctly. It's a pain if you don't- they can
grab the wire and really mess things and time up.

I use the same press that I use for pressing frets to set the rods/magnets.
Different pups are sized differently so I use Maple spacers to keep things right.

After all the rods are in place I run a little super-glue around them to help stabilize everything and
then I spray a light coat of urethane. It's suppose to help keep them from shorting out and add some
protection should they get wet.

 
Tomorrow, I'll magnetize them and get to winding.

Alright, making pickups.....this is getting even better, Spacey. I am eager to see how you magnetize them. Do you buy the basic components to the pickups cut to shape, or are you making the plates from scratch?

I buy the pieces.
Pretty easy to magnetize. I'll be using Alnico 5 - South up.
They may be to bright but I don't have Alnico 2 on hand but no big deal to change if need be....much cheaper to build them and modify if I want.
 
 
Two good magnets to pass the bobbin through.

Meter showing no charge.

After passing through the magnets. (Alnico 2 would probably max at @25)

 
What I didn't do was bevel the top of the rods like Fender did. I should, it would make it easier to
punch them through the vulcanized fiberboard (flatwork). That stuff is tuff. Easy to by sheets of it but
I don't have a laser cnc .

Completed the Alnico 5's.
Used 42 AWG PE.
(took readings this morning so they have cooled and are at room temp.)
Used 8500 winds for bridge- 6.42k
8400 for middle- 6.25
8300 for neck- 6.15
 
Grey bottom and wrapped.

Potted. ( don't do unless you know about the hazards)

Out of the wax. Readings will be higher- I got a 7.1+ on the bridge while hot.

 
A plastic pup cover can still be used.
 
I'll be building three more for this build.
It's said that the A5's are good for "warmer" woods and A2's are good for "brighter" woods.
I'll find out how true that is for me.
 
A tip;
 
Since many of the Strats have plastic bobbins it's easy to make a major upgrade and much cheaper
than purchasing new pups.
Get Alnico's and replace the steel ones- you can tell if yours have the cheap steel ones because there will be two magnet bars glued to the bottom of the pups.
 
There are two different rod diameters used, .187 and .195 - easy enough to measure and get the right Alnico ones that are @ $2.00 ea. So for about $12.00 per pup you can make a major tone change to the guitar. That sure beats $200.00 for a new set (3).
They are also offered in different lengths. One may be able to use one length and set as preferred it doesn't hurt if some extend out the bottom if there is room in cavity when pup height is determined.
 
The coil wire doesn't contact the magnets/rods with a plastic bobbin so it's hard to damage the pup changing the rods...but I know that some could.
Mojotone is where I like to get pup parts.
Yes you'll need two magnets as they don't arrive charged.
 
So for the price of about one pickup all three can be upgraded. I know many members here talk about making upgrades to their lower end models...this is the first one I'd do. This and knowing how important adjusting them is, is the place to start IMO.
 
Time for more coffee. Hope you enjoyed.

Cool stuff Michael!
(BTW - I'm hotter when potted too.  )

Based on some recommendations, I've used a guy on ebay (who's cheaper and sells magnetized stuff) to get different magnets for a PU I wasn't happy with:

Not sure whether Mojotone has any advantages or not.

i just buy bill lawrence wilde pickups...
it's quicker.
LOL

Craig- it's fun. I have a great time making them. Especially when I hook them up to the meter and get a reading! Glad some are enjoying the trip.
 
Drew it's sure great now that we have options to get parts. I wish it would have been that way when I was young.
 
Bat...nothing wrong with that. I turned 59 in May...I'm not in hurry about much of anything anymore.
