humbucker baseplate made in resin help!!!

[cenizasblancas]

Hi i want to know if is posible to use some material between a plastic humbucker baseplate, and a magnet for mantain the magnetism of an alnico magnet, without making to much eddy current, because i can´t found nickel silver baseplate around here.

Thanks !!!

try these

but my problem is not the baseplate because i can made it from resin, i need some material to use between the baseplate and the magnet.

Try it with and without the steel insert.
Some of the mini buckers have a thin piece of steel sheet metal to tie the 2 Alnico magnets together under the bobbins.
You could try a thin piece of sheet steel under the Alnico magnet.
You would need to ground it.
The sheet steel should make it a bit darker if the pickup is too bright with just the resin baseplate.
The sheet metal needs to be pulled down snug, it may be a source of microphonics, but wax Potting should cure that.

Thanks Terry!!!
It´s important the type of steel? stainless steel?

No, I don't think so, I would use magnetic steel.
Try it without any metal, then add the steel, and experiment until you get what you like.
That is what I do.
Lots of trial and error!

Wow with very little detail about what style of pickup used, you got it ,there must be a reason to put something between the magnet & the base......

In the case of not using steel, How quickly alnico magnets are demagnetized?

If you are talking about standard Humbucker Bar Magnets?
As long as you get a good charge on them to start with, I don't see a problem, with or without metal.
I have noticed it is hard to get a even charge on bar magnets.
If your not careful, the running them through from one end to the other, you end up with more charge on the end that just left the NEO magnets.
It is easy to see this with a Gauss test meter.
The different metals in between the magnet and the fiber or resin base plate, will add eddie currents.
If the Pickup is too bright that would be a good thing.
If anyone else has any insight they want to add on this please do.
An interesting topic.

If you need raw "nickel silver" sheet metal, you can get it in Buenos Aires as "Alpaca".
Or ask any hippie artisan guy at the "Feria de artesanías", they use it all the time for handmade jewelry.
Maybe they can give you a small piece to experiment, without buying the full sheet.
And ... good luck

Here is the template to make your own baseplate, if you can get the metal.
The steel bar in the PDF is the important thing.
You do everything with the vise and the bar, and a hammer.

Yes you are right, i´m going to ask some hippies, ja ja.

About this... i only have 2 neo disk, so... Do I need to buy rectangular neos? because i don´t have gauss metter.

It's hard to get an even charge on bar magnets with 2 disks.
You can get an idea of the charge by taking a steel object and checking the gauss magnetic strength up and down each side of the bar magnet.
If you have weak places, and stronger places on the bar, then you are not getting an even charge.
You can see it much better with a gauss meter, but the steel object, like the end of a punch, works too.

What size do you recommend for charging magnets including the size for eight strings magnets? (in the future I want to experiment with this)

i´m going to send an email to Shea.

thanks

Why? You do not need anything between the baseplate and the magnet. On a humbucker the baseplate is not magnetic. If it were, you would short out the magnet circuit and get very little output from the pickup.

I make humbuckers all the time without a metal baseplate.
