need advice on reversing my motor

[walcen]

Thanks David, Thanks David,Thanks David and Thanks Llanonite.
Man what a mouth full LOL.

Twisting the belt is a great idea, and if I weer to use a wide ish flat belt it probably wouldn't rub at all.

Flipping the bobbins over is also good but I wasn't sure if all bobbins could be flipped.

And I'm gadget kinda bloke too, it's how I learn stuff and have fun.

Ultimately I'm trying to design a cheep, easy to build but effective, durable and versatile coil winder with the hope that others may benefit from the design.

Some of the guys on the Aus woodworking musical instrument forum checked out the Schatten winder, that thing costs $500.00 Aus not to mention postage, I don't think it's worth it and it's some what lacking in quality.

Anyway I digress LOL

Kind regards to all

Walt, my point about reversing the motor is also that there is really no need to ever wind a coil in the reverse direction. It has become common for single coil pickups when you want to hum cancel, but you really only need to reverse the two wires from the pickup when wiring it up.

I have a Schatten, and I've only once used the left side of the machine to wind a coil in reverse. And currently I have an electric hand drill chucked to the shaft on that side to power the winder.

It's not a bad little winder, but it's not really made for continuous duty. At least that's the way Les Schatten made it sound. It's more for taking down off a shelf and doing a rewind, and then putting it back. It's not a cheap machine because its hand made.

Mine has served me well for the past 4 years, but now it's time for something new.

Certainly you can make a cheaper home made winder. I remember seeing some very simple winders made from electric hand drills mounted on a wooden frame, and initially I thought those were kind of funny. But after using a drill to power mine, I think it's a good alternative for someone who just wants to wind a few pickups.

Now, I'm not being a smart ___, but if you want to reverse wind, why not set up behind the winder and wind from the Back of the winder rather than the front. AKA, don't reverse the winder, set up like normal, except put the tensioner/tension bar/finger/whatever behind the winder?
I know that you will be top-winding and some people say that it can cause technical issues (although I must admit that I don't completely understand exactly how it would)

Also - reverse winding and reverse wiring are separate entities that can help remove hum. Reverse wiring may affect tone because of the difference of the magnetic field on the inside of the coil rather than the outside - HOWEVER I am not an experienced winder and I do not know if it is a signifcant effect and alters tone.

[David King]

I've never heard anyone make that claim either.

The only reason I do it is because I can just look at any pair of pickup I've made and always know where the white and black wire are going to go. Never any confusion -provided that I always put the north end of the bobbins towards my winder..

No matter where you feed your wire from the bobbin is still rotating in the same direction.

I made my winder two sided. I just move to the other side of the machine.

No, people only reverse wind when they are doing a RWRP (reverse wind/reverse (magnet) polarity) pickup to cancel hum with a non reverse pickup. But it's unnecessary. As long as the magnets are opposite, all you need to do is reverse the wires on one pickup. That's how Gibson humbuckers work.

Some people think that having the ground on the inside near the magnets might reduce capacitance, or that having the ground on the outside might shield the coil, but I don't have an opinion on that.

The magnetic field just makes the current flow... in one direction or the other.

I do the same thing. I put the top of the bobbin toward the faceplate. I use a white wire as a start, and a black wire as the finish. I do every coil the same way.

I did a couple of humbuckers with reversed coils, but it was too damn confusing!

I might start using eyelets on some of them.

Hey guys thanks for the response, I really appreciate your help and now I think I'm armed with enough knowledge to go forth and conker.

I'm currently building my first guitar, a Les Paul and I'm doing it all from scratch and I want to do as much as possible my self. this proses can be difficult because in order to make something, one often needs to make something else to facilitate in making the first thing and hence the learning proses continues.

kind regards

conkers - A game for two players in which the participants each have a horse chestnut (known as a "conker") suspended from a length of string and take it in turns to strike their opponent's conker with their own with the object of destroying the's opponent's conker before their own is destroyed

Have fun with that.

[David Schwab]

Have fun with that.

And to think, all these years of picking up horse chestnuts, and I never found a use for them!

Where I grew up, two houses over they had two horse chestnut trees. All the kids used to gather them up... but of course there was no point to the whole exercise, except they are kind of cool looking... although the nut case would make a nice weapon!

Walt, we are teasing you... the word is spelled "conquer".

Ultimately I'm trying to design a cheep, easy to build but effective, durable and versatile coil winder with the hope that others may benefit from the design.

1 sewing machine motor
1 wooden box
A few shaft collars
2 bearings
1 shaft
I had a pulley something like this kicking around the house, I just epoxied a shaft collar to it to make it fixed to the shaft. You want something lightweight.
A piece of 1/8" aluminum cut to length and stuck to one of the collars using this stuff
An old drawer pull with a couple guitar picks drilled to fit to act as a guide
Your belt of choice

Rig up the counter of your choice (the bicycle odometer approach works for me)

This may not be the way to go for production use, but for winding a few bobbins now and then it serves me well.

[Bruce Johnson]

I think that the idea of arming yourself with enough knowledge to go forth and conker, is in itself, very brave and admirable.

[walcen]

Go forth and _ _ _ what?

Thanks David And David and Dave, oh man you can't say Dave's not here man around here LOL .

Ive worked with scientists who couldn't tie shoe laces, use a microwave oven or drive a car but they were all good at ONE thing.

I can turn my hand at a great deal of things in life from automotive fuel injection computers to building my own house, BUT I CAN'T SPELL FOR SH+#%T , so shoot me LLLOL

Yeah, me too! I'd work with these brilliant engineers at ITT that would do all these crazy microwave and digital stuff, and then ask me all these questions about audio circuits... that that seemed really simple to me.

I guess it's what you specialize in.
