I measured the original wire on the stator before I took it off, i measured 2.4 inches, and the stator is 1 inch thick (actually 17/16ths), so you have 0.7 inches of wire sticking out on each side, so I want a diameter of PVC pipe that gives me about 2.4 inches when i put the coils in and press them squarish, because the coils wont go in round, they are more rectangle-like. I just happen to have two PVC pipes, 1 & 11/16ths, and 1 & 13/16ths and I found the ideal diameter in between that, so I will make a slight adjustments when I build the jig so that the wire loops will be the desired size.

have to run, back in a bit

I too thought that Kevin was winding his coils wrong.I just bought a ford core and took it apart.The coils are wound just like Kevin does.I was shocked.But my Denso is wound like the S wave method.So they are done both ways depending on the brand you use.My friend has a delco and it's also wound like Kevins.

oh ok so they do wind them in both manners.. i have only acknowledge the s wind style...  i think im gonna build my jig out of a piece of 2x6 board and a piece of 1/2 by 6 (plywood mabe).. them sandwiched together should give around 2.4... i will cut it into a circle to match the diameter of the core from cavity bottom across to cavity bottom.... then i will mark every 30 degrees around the solid wooden wheel like object... i will use a jig say or band saw to cut matching cavitys to match the cores dementions all the way around for a single phase.. i will mount it like a wheel so it can rotate freely..

I went to the motor repair shop today, we did a job for them in the machine shop, and while i was dropping that off I was talking to one of the guys about my alternator, and he let me borrow this old winding machine:

So now i'll make up a coil form out of PVC pipe with consideration for 14 coils, and this will make life a lot easier, it has a counter, and you press a lever down to move the motor assembly into contact with the drive belt to make the coil form rotate, this should give decent control over winding speed.

I'll post a picture of my coil form when i finish it.

My diodes arrived!

Yeah, I was only creating the coils to be inserted in the 42 slots of the stator.  There is a lot to the spacing, every third one for each string of 14 coils.  Then the next string has to deal with every third space as well, and so on.

And this is only for delco remy

Sorry it was clear as mud.

I hope to respool one soon so I can relate the firsthand nature of it

The ford alternator only has 36 windows in the stator

36 indeed, hmm, i guess that is 12 loops? I'll have to count carefully before I start making my coil form.

Christmas is here! This will slow down my winding progress for 2 days.

I want to talk about some thoughts on this circuit:

(http://img.photobucket.com/albums/v81/bigbuba/Picture14-3.png)

This circuit is a pulsed alternator. There is a combination of the mechanical and electrical input frequencies.

There are no chokes (shown).

This is not a 3 phase set up because only one phase is used per tube.

There are two grounds used for each phase, one before the cell and one after the cell.

The center point or neutral of the three phases is not connected to anything, but all phases are connected to each other.

He is using a variable resistor on the negative to "tune" the amp leakage, this can be replaced with a choke, and a choke could be placed on the positive line to match it.

The ground on the positive side is interesting, I am not completely sure what this would do, but it looks like it is the "isolated ground" that would keep the positive pulse from swinging negative. Usually it is shown before the secondary, but all our secondaries are tied together, so he put it after the secondary. Or, this circuit probably pre-dates the VIC, which is why he might have tried his isolated ground here first.
