neodymium pickup design configuration

[sihama]

Hello I am making pickups with 44 awg wire for a 7 string but I have a couple of questions maybe someone could help me .
1. I wanted to use rod neodymium magnets under screws like poles but the 2mm X 3mm i bought magnets don't seem strong enough to me.... i am looking at buying 10 X 4 mm ones but will they be strong enough?
2.which would be the best size?
3.I thought i could make humbucking blade (rail ) pickups by puting 7mm x7mm(3.5 radius) rods under them with all the north polls on one blade and all the south attaching the other blade would this work??
4. using 3 pcs 25X 15X 5 mm blocks in line with the magnetic field through the 5mm....

which would work the best? i cant find 60 x 7 x2 mm ( magnetic field through 2 ) bars used in comercial neodymium blade(rail) pickups
if you need design drawings please tell me!

Welcome!
Maybe others will chime in here.
I would think the NEOs between the bottom of the blades would be a good Option, and they would be humbucking.
Not sure where you are located, and what parts you have Available?
You could easily make a humbucking pickup in a EMG type bass cover.
Mojotone EMG Style 2-Hole Mount Soapbar Bass Neck Pickup Cover Black (4 String)
These are designed to use bobbins with ceramic magnets in the bobbins.
That would be fairly quick and Cheap.
Or you could put blades and neos with bobbins.

Here's the magnet from one of my prototypes, that would fit in a humbucker in place of the thicker .187" bar magnets
I used small neo magnets glued to wood spacer

copperheadroads, .187 that is 4.7498mm diameter and hight? they look like 12- 14 mm. where they stronger than "normal magnets " did they pull on strings?
budget seems to go high if you buy rods taller then 10mm ....

big_teee,I am going to make them as diy as possible ...probably from bubinga scrap wood. blades seem to be the cheapest solution less magnets .I Live in Greece.

No , it was a quite usable tone without pulling strings ,adjust them a little lower ,something like a super distortion gauss at the poles

If there's too much string pull, drop the pole screws but keep the coil(s) reasonably close to the strings. Output drops as the square of the distance from string to coil(s)...

Why not use a piece of mild steel instead of the wood?

My intention at the time of this pic was produce a bright high output humbucker .If I wanted a warmer tone ,your Ideal will probably work quite well David .

Then I would use ceramic magnets. With the size of the neos you are using, bridging them will give you more output. I use neos that span across both coils.
