That's the kind of input that this thread needs !

Ok, back to winding.
I've come up with these (6) six options for double winds. Open for opinions.

Use drawing 1 or 2. You, nor anyone else, will ever be able to wind the other four accurately. If I was winding, I'd put the larger gauge on first. By heavy & light, to mean larger gauge & smaller gauge? Why not just wrap them together? I'd also wind single gauge first, until I was good at it, before attempting doubles & triples.

[Mark Onofri]

Yes BillNH , heavy would be
a larger gauge.
The drawing is just all the combinations I could think of.
In 5 & 6, I tried it. Not in any specific order. Just (2) two wires of the same gauge.
Believe it or not, it wasn't that much harder.
Is Mr. Faraday a member of this site ?

In this picture ( previously posted) the stack that is NOT in the fixture is (2) two of the same gauge wires , wound at the same time.

 Regardless of all the possible ways of doing a double, triple or even more wind, with the same or different gauges, the standard  and easiest has been to just do all the strands at the same time as in your 5 & 6.

 

Triples were a waste of time, even though Mura produced some, 27/28/29 for instance.

 

Doubles such as 27/28 & 26/27 were quite common until 24 1/2 & 23 1/2 gauge wire became available.

 

There's really no use for anything but singles for any reason other than the doing of it for grins, multiples are less consistent performance-wise.

 

But what about star winds?       

[Bill from NH]

Not only Mura, but Howkill, north of Boston, had some flaky triple winds also.

 

In the early 70s, we ran 27/28s on power-supply tracks to lessen a motor's power needs. It didn't always work.

[Mark Onofri]

Jimht, I'm glad you said that. I actually thought it was easier to wind (2) two gauge sizes (ok BillNh) at once.
Whether it's a waist or time or not, a lot of bloggers(?) are into the period thing. So for the benefit of them and , my own curiosity, I'm going to include it .

[Mark Onofri]

On a closing note for the evening:
Gauge [(1)+(2)]2-3=gauge(3)
Ps: did I mention that I'm going to disemboweled my phone and use its circuits as a noose when I hang it from the highest tree. No offense Noose. I can't write the formula in the notation that every one is used to. I'm sure BillNH will reprimand me for this.

[Mark Onofri]

Jimht, in the first page of this thread I posted the equivalent of my rewinding a (5,7) five or seven pole armature . BillNH suggested I stick () to Velcro.
Why not!!?
But first, let's get through (3)three pole winds.

[Mark Onofri]

Ok, how many poles can I wind with this com? Bill(eagle eye)NH I bet you get it first.

Missing comm slots?

[Mark Onofri]

Yep,

[Mark Onofri]

I was all set to wind a 36-DD with #29 wire. As luck would have it, no #29. I have some but, it's in a Lagank kit. Wanted to save that until I have more experience.

[Mark Onofri]

I seems that if you dig deep enough, most of the answers are scattered in posts in numerous threads.
Should I change direction and compile what I think is pertanent or, keep going like this ?

[Mark Onofri]

Any one have a drawing on how to tie the arm? No BillNH ,I can't use Velcro 😂.

[Bill from NH]

You want a bow knot?

[Mark Onofri]

Kinda left this one on the back burner while I was doing the dc65-x tribute. Going to clean up the garage (aka work bench) and get back to it shortly.

[Mark Onofri]

Ok, explain this one to me. Sandy Gross had a 16-D with, and I quote:
48t/#27
Somewhere in this thread it is listed that a G27 has 27/27.
Is it me? How can you get 48t on a 16 pole if you can only get 27 on a arm of roughly the same dimension ?
Or is it 48÷3=19 per pole. That seems reasonable.

[Bill from NH]

19T of 27 sounds hot!  You need to find that Sandy Gross post again & reread it. I do not know where you saw it.

 

Grp.27 is 38T of 27 hand wound on a .440 stack of any diameter.

Jairus, I believe, build a copy of this Sandy Gross Lola. If 48 isn't a typo, it's only 10 more turns than a Grp. 20/27. The article doesn't specify what  the arm blank used was. It might have been thin webbed or just been wound neater, The wire used back then could have had thinner insulation than todays. So, there isn't necessarily any one reason how they got 10 extra turns on it compared to a Grp. 20/27. My guess is they used a blank with more wire winding space & everything was wound very neatly..

[Mark Onofri]

Brain fade. I stand corrected,38/27 for a g-27. Yah,lots of variables.
I'm thinking (really, I am) it's a good place to start.
Comments ?

[Bill from NH]

So is a Deathstar,

[Mark Onofri]

I've got a lot of cooked 16-D's & a lot of #27 wire.
Just waiting for a holder. I've wound a couple a 2,3 without one. After I tried one, I can't imagine not using one.
