What are you attempting to wind here, or are you just having winding practice? You need to make a rack to hold your spool of wire & be able to use a screw & washer to maintain a constant tension on the wire coming off the spool.

[Mark Onofri]

BillNH,I thought I explained that in the post with the vacu-vice?
I'm (re)using the wire as, and if I can. Seems like the thinner the wire, the harder it is to wind.
It's just practice at this point. I'll take your suggestion & set up a unspooled wire reciver. Maybe with Velcro 😆.

Ps: a lot of threads unrelated specifically to motor building have some GREAT information & history from when this was the norm.

[Mark Onofri]

Another thing I think will be helpful is a copy of the Simco drawing pinned to the wall. Maybe I'll add some colour to it.

[Mark Onofri]

I found that if I go by feet, it leaves me with more (diminished) mental capacity to focus on winding. Also, I always wondered if you go by turns, would the length be the same?
If you knew me, you would know that I counted as I unwound & measured the #feet simultaneously.
~=57/ ? Witch is ~=6'
So I have 57 turns of whatever wire is on a 36DD

Let's see what ~67 turns looks like shall we ?
But first, a word from my sponsor.

[Bill from NH]

Winding by the foot length is more accurate than winding by the number of turns, but requires more work, so not many wind that way. If you can keep a constant tension on the wire, winding by turns works well. Practice winding with the same gage you plan to use, Don't use 32 for practicing how to wind 28. Planet Engineers is one source to get good wire. You may find some on eBay too.

[Mark Onofri]

Thanks BillNH. What I did was to drive (2) two nails above the winder,12"apart and, I compensated for the nails. I thought about your nut& washer suggestion, it makes sense. But I'm using used wire. When I get to new wire, that's the way to go.
If you were fishing , would you use a:
Zebco 202
Or
A open face Garcia
?
(Bear with me it's pertinent)

[Bill from NH]

When my kids were kids 30 years, both had Zebco rods & reels, but I don't recall the model. I used several different spinning reels as well as casting reels. They all sit up in my attic unused today.  We only fished rivers, streams, & lakes with lightweight tackle. We wouldn't have had any Garcia or other open face reels.

G40 was definitely a Camen deal.

I don't remember if it was a 26AWG class, or 38T of 27, but on a short stack.

I also don't remember hearing of a race ever being held.

[Mark Onofri]

If you take a close look at the Dyna-rewinder, it looks to me like a modified Zebko 202. The Garcia open face has left to right then right to left action.
I was piping some roof drains on the upper turbine deck(185"up) of a cogeneration plant when , I noticed two men doing something with the turbines.
I began to wonder.
As it turns out, they were two engineers from Toshiba power generation systems (or something like that)
Once we got past the language barrier they explained to me that fishing line was the best way to gauge whether or not the turbine shafts were in alignment or not. Okay if you say so. They were there every night for as long as I was. It turned out that I had a supply of sake, which led to many interesting conversations about zero shaft speed at center line cuz ,the center line can't turn.
Anyway,a fishing reel (modified) to hold wire would give a (semi) precise action for winding.
Just a fleeting though.

[Mark Onofri]

Mike, did you see how much (2) two Camen motors & (5) five dbl/w arms went for on evil bay last week ?

[MSwiss]

No, I don't go on Ebay to browse.

It would take up too much of my time.

I'm not surprised if they commanded pretty good money.

I had a small handful of Pooch double winds , from doing a buyout, in 1983.

I don't remember selling them, so I may come across them some day, in my basement crawl space.

I also had a Pony Express that I bought before I got involved with Stu Koford.

It was a nice piece.

Great craftmanship, cool name.

It's about 50-50 whether I still have it.

[Bill from NH]

Mark, a fishing reel might be a good way to maintain & change a wire's tension when rewinding. If you ever use one, let us know.

 

Mark, in the day, not all Camen arms & motors ran like "Team Camen" arms & motors. I know of several that didn't, not only mine. But it was the major reason I went to Rocket & Steube arms. I would think today Camen anything would be highly collectable.

$417.81 U.S. presidents. I figured $250.00 but, it dawned on me that I couldn't drive them then, probably can't drive them now. I'll stop at G-20.

[Mark Onofri]

The nice thing about being new to this is I don't have any clues to what I'm doing which, can be a benefit ,for once in my life. In this case, I didn't have anyone to tell me that I could not use two wires at the same time to do a double winde. It was actually pretty easy. There's a bout 21 ft on this pole.
Comments? Questions? Nay Sayers?

The upper pole is ~=67t or ~9"

[Bill from NH]

Do you mean above to say the pole is wound with 67 turns or about 9 feet? I worked five years for a guy from Naples, but sometimes I have a problem understanding your Italian.   

 

Double winds can be wound with either two wires at a time. or with two separate wires. Separate wires may look neater, but both ways work.

 

Helpful hint: The last pole usually has space limitations when winding, Use the edge of a popsicle stick to compress windings & make room.

[Mark Onofri]

A Ohh ahhy. I'm sayin wat I'm sayin. 😂 Forgetboutit. The stack in the holder has 67 t

I don't remember if it was a 26AWG class, or 38T of 27, but on a short stack.

I also don't remember hearing of a race ever being held.

As I recall I think the Camen arm was "C40"?...Joel's attempt to produce a machine wound armature that would be competitive with the hand wound Gp27 armatures and less expensive.

 

I don't have any left laying around but It was 38 turns of #27 on a short stack blank (.350") and therefore would make the dimensions of a 27 setup the same as Open and C12, making it easier to transition from one to the other.

 

I liked the idea and promoted it but "THE USRA" (LOL) was resistant..."No, no, no, cheaper and competitive means all my stuff would be more expensively obsolete and newbies would be competitive without having to pay their dues like everyone else did." So the arms were never USRA legal.

 

The G40 was different, discussed here: http://slotblog.net/...e-2#entry699446

[Mark Onofri]

Thanks Jimmy. When and if I can get all the armature information, I'll put it in a separate thread for reference. I was almost there until, my previous phone met with a untimely demise.

[Mark Onofri]

This phone is close to an abrupt end also.
Jimht. It only spell corrects if I don't want it to.

[Mark Onofri]

So everyone agrees
C-40 .350D, .513L, 38/27
Ok

C-40 .350D, .513L, 38/27

No.

 

C40: .350"L, .480"-.500"D, 38T27. Made for Cobalt setups.

 

Group40: .490"L, .512"D, 30T26 (the wind is an estimate). Made for C can setups.
