Despite my best efforts, I still don't see a lot of (or any) home-winding going on... why not? Recently, I've been back at the minican motors doing a bunch of the Hawks and PS4002 variants, and these are a good candidate. They're inexpensive, and there are enough of them used, so they could even be free. You can learn how to take them apart and reuse them, so all you really need is:

* a very few hand tools you already have (needle nose pliers, X-Acto knife, screwdriver, etc.)
* a soldering iron you already have

* a half pound spool of say some #30 wire (a few bucks on eBay)
* a winding crank you can make easily and a clamp you can have made or buy.

It's better to have unbalanced versions of the motors, but even the balanced versions will run OK. D motors are still plentiful as well, and their larger size makes them a little easier to work on.  

 

Helloooo... "can you hear me how?"

- because you're doing a far better job at it than I can

- you buy quality glue in bulk I can't afford for just an arm here and an arm there. Can't buy the good stuff over the counter like 1969.

As Pablo said, you do it better than I have the time to learn to do it. Noose and Steve Koepp paint better, Tony P and Bud Bartos build better chassis than I can. What you need is an apprentice because when you are done (hopefully not for a long long time) there will be no one to carry on.

I don't buy the glue in bulk, Pablo. I buy it in one-pint trial-size, and more than one person could chip-in to buy the stuff. Oh and, the "good stuff" over the counter in 1969 was nowhere near actual "good stuff," it was just probably better than what you get in the hardware store now!   :)
 

As Pablo said you do it better than I have the time to learn to do it. Noose and Steve Koepp paint better, Tony P and Bud Bartos build better chassis than I can

 
Well, that doesn't make any sense, Bill. Why build chassis or paint bodies at all then? There will always be people better and worse at anything you can think of. Winding is just like painting and chassis-building, it's crafty and fun, and others having done things before us should never be a reason to not do something. No one would be doing anything if that were how people looked at all sorts of things!

John,

 

It comes down to time. I am closer to the end than the beginning so I have to choose what is important in what little is left, I think that is the same for the majority on this site.

 

If you can find a younger person to pursue this that should be your focus.

I think an interesting approach would be if there is an endbell that readily fits the Retro Hawk Motor and the fact that there are so many of these motors out there and eventually burn up it could be an interesting exercise to "resurrect" on of these motors. The stock arms look easy to strip the old wire off.

 

The question would be if the comm would be re-useable. If it is not is there a readily-available aftermarket one? Also some reference points for the timing marks based on the reorientation of the brushes with an endbell arrangement.  Cost to rebalance could be a factor also, but not insurmountable.

 

Sounds like a blast from the past or at least an electrical flash from the past.

I definitely plan on trying to wind a few ,especially since I know more now than when I first tried to do it. If anyone wants to share/split some of the stuff like epoxy I'd like to hear from you.

 

I even have my eye on a winding tool at Micheal's that is meant for making wire jewelry. I think with a little work it'd suffice to get started winding arms and it's less than $10-15.

 

The reason I havent just yet is the costs, granted it's not a lot but right now I'm concentrating on my race program more than other aspects.

 

But as I said earlier if someone wants to split some of the epoxy I'd pull the trigger and give it a go. It's just right now I can't justify the costs on something that most would go to waste so hopefully someone else here is on the fence, too.

Like Bill said, "time."

There are a ton of fun projects, myself and others, would like to tackle, but only have so much time in the day.

Also, a good portion of Slotbloggers race, and 99% of racing these days is running spec motors, as manufactured by the factory.

Not only is rewinding not required, it's illegal.

I wound my lifetime quota of arms when I was in my teens. A good portion of them went up in smoke, but it's the thought that counts.

John,

 

I “get it” (as if I even had to say that).

 

However, rabid racers don’t, and probably won’t. In fact most will argue they can’t.

 

Some might even go as far as saying they shouldn’t, and neither should you (or I).

 

Unfortunately, we are trapped in the 21st century.

 

What a shame…  Build on! :D

Steve,

 

Your post smacks of "you should be enjoying this hobby the way I/we do."

The jillion views, compliments, words of encouragement, and advice are proof no one is discouraging or suggesting John should stop winding.

John,

 

While there might not be many takers as far as rewinding armatures the work you do and the instruction you give does not fall on deaf ears. You are a true master craftsman and I and others are lucky to have you on Slotblog. Your work is valued and respected.

Take a break if you must but please never stop the lovely work that you are doing. Slot cars would be much the poorer if you got discouraged.

Mike,

 

Please allow me to clarify: "You should be enjoying this hobby the way that most pleases you" (no smacking required) :laugh2: .

 

If it is being a rabid racer, fine. If it is owning and operating a commercial raceway, fine. If it is building motors or chassis or whole cars that are not allowed to run in races in the 21st century... that's fine, too.

 

In my case, you are correct; for me this is a hobby, an avocation, engaged in for the simple (and timeless) joy of doing it. Not subject to topical rules or culture.

 

Racing miniature cars, like racing full size cars, is in my view properly identified as a sport. It rightly includes rules, competition, excitement, and lots of controversy.

 

Both implementations of our mutual interest are equally valid. It pleases me greatly to know we agree that John should not stop winding.  :good:

To add to the many other points that have been listed, I will not be showing the comms/arms that I have destroyed LOL! 

 

I know that you may think that nobody is trying but the truth of the matter may be that "we" just haven't been able to come up with that arm that is functional yet. I, being terrified of the possibility of electrocution, have a documented fear of electricity. I tried to solder the connections on one of my attempts. I know you already know the end result. I never knew that arms got that hot. 

 

Then I tried the welding. First thing that happened resulted in a big spark, and one entire segment of the comm vaporised. Once I changed my pants and stopped saying every four-lettered word I knew (and a couple made for the occasion), I put everything down. 

 

Just recently I've decided to try again and made a purchase from Bill of stacks and comms. I do believe that once I'm able to get a weld that will hold and not scare the shirt out of me, I will be able to have something to show. 

 

It isn't easy! Your work keeps me motivated. I know that I have expressed this to you in the past, but once again, I would be willing to attend a "class" to learn. I see from time to time that painting classes/seminars are offered at some of the tracks. Would it be feasible to hold winding seminars so that people can get an idea of the best way to do things at "local" tracks? For instance, instead of a race, see if enough people would be interested in paying for materials to come to build then run what they built? 

 

I do think that people would do more with this aspect of the hobby if there was something that could be done with the motors on a larger scale than what is "allowed" at this time.

This. Rewinding Is fun and I rewound a few R/C arms way back in the day, but it serves no useful purpose for racers.

Hi Bill,
 
Well then, I get why you're not into trying it... and my post wasn't aimed at you or anyone "specifically." Certainly someone who has the time and is a little interested would be my prime target.
 

I think an interesting approach would be if there is an endbell that readily fits the Retro Hawk Motor and the fact that there are so many of these motors out there and eventually burn up it could be an interesting exercise to "resurrect" on of these motors. The stock arms look easy to strip the old wire off.

 

The question would be if the comm would be re-useable. If it is not is there a readily-available aftermarket one? Also some reference points for the timing marks based on the reorientation of the brushes with an endbell arrangement.  Cost to rebalance could be a factor also, but not insurmountable.

 

Hi Steve,
 
I think the Hawk and PS4002 endbells might fit them... or be close enough, but even one set-up can be used and reused again and again to test arms. As I mentioned earlier, the D motors are a little easier because of their size. The comms on the Hawk and PS4002 are reusable, it just takes a little yanking around to get them open is all. There have also been loads of Tradeship comms on eBay lately, and those are absolutely fine for milder winds... and you can solder those winds as well. You don't even need to consider balancing until the winding part starts to make sense.
 

John,
 
I “get it” (as if I even had to say that).
 
However, rabid racers don’t, and probably won’t.  In fact most will argue they can’t.
 
Some might even go as far as saying they shouldn’t, and neither should you (or I).
 
Unfortunately, we are trapped in the 21st century.
 
What a shame…  Build on!

 
Oh, I know you get it, Steve, and there are still people who build and run vintage "style" cars.  :)  I mean, I've done a lot of motors and arms for people, so they're going somewhere!?  Sealed motor racing is cool and all, and this doesn't have to have any bearing on all that.
 

 I know that I have expressed this to you in the past, but once again, I would be willing to attend a "class" to learn.

 
Someone had mentioned this some time ago, I think it was at Buzzarama in Brooklyn. Anyway, I said I would do it, but nothing ever became of it. I can't see myself going to Ohio though, Brooklyn would be far enough, and Port Jefferson would be far better!   :D

Hi Mike...

 

Yep, I fully understand the time thing, and winding has meant putting aside other stuff I like to do, and that part is starting to bother me. I also get the racing thing, and it really has nothing to do with this. There have been a good number of people who have expressed interest in all this either publicly or in PMs. Bill Bugenis has sold parts to people as well. Then too, there are vintage races in Europe that allow all sorts of motors, and I send a bunch over there. At the bleeding edge, there are still open classes where anything goes, and I do work for people whose local rules allow for handwound arms.  

 

However, these arms and motors don't have to be raced, they run just fine without track marshals and lane stickers :) so the no-nos involved with sealed motor racing aren't really applicable. This is more about "vintage" and just pure fun than racing, and it's a real hoot to see your car scoot for the first time with an arm you wound. Like 1965 all over again!   :D

Well again, there are more people doing slots than just racers, and some racers' local rules (both here and abroad) allow handwound arms and motors with no seals. So if a person is a racer, and doesn't want to try this, he needs to understand that there are others for whom this all is available.  

 

When I started doing this again, some years back, I got a fair number of "Why would you do that when you can just buy motors?", which is a different sort of thing than "my racing doesn't allow this." Then why scratchbuild or paint bodies?

This isn't about racing, so if that's all you want to do (which is a great thing!), then my question wasn't even aimed at those folks.

John,

 

Been meaning to follow up on this, but I wanted to get to a real computer where it's easier to use some quotes.

 

Get ready for some tough love.

 

Despite my best efforts, I still don't see a lot of (or any) home-winding going on...why not?  Recently, I've been back at the minican motors doing a bunch of the Hawks and PS4002 variants, and these are a good candidate.  They're inexpensive, and there are enough of them used, so they could even be free.  You can learn how to take them apart and reuse them, so all you really need is:

* a very few hand tools you already have (needle nose pliers, X-Acto knife, screwdriver etc.)
* a soldering iron you already have

* a half pound spool of say some #30 wire (*a few bucks on eBay)
* a winding crank you can make easily and a clamp you can have made or buy.

It's better to have unbalanced versions of the motors, but even the balanced versions will run OK.  D motors are still plentiful as well, and their larger size makes them a little easier to work on.  Helloooo..."can you hear me how?".

 

 I tried to solder the connections on one of my attempts.  I know you already know the end result.  I never knew that arms got that hot.  Then I tried the welding.  First thing that happened resulted in a big spark, and one entire segment of the comm vaporised.  

 

So you portrayed winding as an easy hobby to get involved in, but it really isn't.

 

You forgot the whole "you really need to braze the comm connection" thing.

 

If guys are going to take the time to get involved, I doubt many, if any, want to do it just to say they did.

 

IOW, what's the point of doing 2 laps, have the solder fly off the comm connections, and starting over?

 

Maybe you need to sell your homemade rig to the interested winder, and post up on You Tube, a video, of your technique.

 

Hi Mike...yep, I fully understand the time thing, and winding has meant putting aside other stuff I like to do, and that part is starting to bother me.  I also get the racing thing, and it really has nothing to do with this.  There have been a good n umber of people who have expressed interest in all this either publicly or in PMs, Bill Bugenis has sold parts to people as well.  Then too, there are vintage races in Europe that allow all sorts of motors, and I send a bunch over there.  At the bleeding edge, there are still open classes where anything goes, and I do work for people whose local rules allow for hand wound arms.  However,  these arms and motors don't have to be raced, they run just fine without track marshals and lane stifckers :) so the no-nos involved with sealed motor racing aren't really applicable.  This is more about "vintage" and just pure fun than racing, and it's a real hoot to see your car scoot for the first time with an arm you wound.  Like 1965 all over again!   :D

 

Of course, everything is not just racing, but people that spend time just blasting around the track, are spending their precious time, doing just that.

 

You have more time to wind, because you don't spend time at the raceway, and that makes you pretty unique.

 

I doubt many, if anyone, who does this as a hobby (not his primary business) has a higher "crafting, to pulling the trigger" ratio.

 

You're like a vegetarian who makes the World's Greatest Hamburger. 

 

And that is fine.

 

But you shouldn't be disappointed that others aren't of your mindset.

 

If you already enjoy doing it, I don't understand why you need kindred spirits also participating in it to keep enjoying it.  

 

But if it is bothering you, like post #13 mentioned, put it aside for awhile.

Hi Mike,
 
Boy, that wasn't all that tough!
 

So you portrayed winding as an easy hobby to get involved in, but it really isn't.
 
You forgot the whole "you really need to braze the comm connection" thing.

 
But *you* forgot* that soldering the comm with #30 winds is completely fine.  ;)  If someone gets that far and has some success, they might want to take it to the next step!
 

Of course, everything is not just racing, but people that spend time just blasting around the track, are spending their precious time, doing just that.

 
I've spoken to more than a few who actually race these things in Europe, and there are some who are winding over there! I'm sending these things all over the planet, somebody's using them.
 

You're like a vegetarian who makes the World's Greatest Hamburger. 
 
And that is fine.

 

That is actually a perfect description... thanks!   :D  I owe you a brewski!
 

But you shouldn't be disappointed that others don't
 
If you already enjoy doing it, I don't understand why you need kindred spirits also participating in it to keep enjoying it.

 

Not so much disappointed as confused. I don't "need" kindred spirits to enjoy it at all, as much as I'd like to be able to share even more. I know that sounds crazy after thousands of posts, but I'm a crazy guy!
 

But if it is bothering you, like post #13 mentioned, put it aside for awhile.

 
Not at all. If I gave the impression that winding is bothering me, it's really more that I have other side interests, and only so much time in the day (the "time" thing mentioned above).

I'd pack my winder up with a couple of blanks and some wire in a heartbeat if people wanted to learn more!

Because it's a good bet that some (much?) of the imbalance that was corrected was due to sloppy coils.

On these motors, the last pole is often piled on top of the other two. That means more wire and more weight on that pole. When you rewind that arm, it's likely that the balancing done would make the arm more out of balance with neater coils than it might have been had it not been balanced at all. Better to start off with a clean dewound arm that's probably "OK" as far as balance.

John, I'd like the glue info, please. You probably posted it years ago in your thread but I'd have to dig deep to find it. That will eliminate one of my biggest excuses.
 
I've never done the weld thing, but I'm sure silver solder will work for me up to the point of arms that need shunts. I could leave those up to you, until you stop providing your services, at which point I'd need to either learn your weld technique, or custom order from the industry.
 
Another factor is, hand cramps. Winding, even using a winder, really is hard on my worn hands.For some reason I get more pleasure from soldering burns than winding cramps  :laugh2:  (little voice in the back of my head says "aw c'mon, Paul, take an 800mg Motrin, eat a banana, and stop crying").  :laugh2:
 
Lack of sources for lams/shafts. There are a zillion arms with straight shafts laying around in this country - too bad almost all have holes in them like Swiss ( :D ) cheese. Those without holes are usually the ones with really thick, and poorly formed, lams.
 
Endbells for vintage motors are almost all used up, at least the ones that collectors desire.
 
Most of us have no clue where to buy a decent comm or decent wire that isn't 50 years old, or of questionable use in a slot car motor.
 
What Swiss said - they are illegal in racing, therefore the demand is low.
 
Nobody can dare say I'm not doing my part - I've built lots of vintage cars and encouraged them to actually be run. 95% of them become shelf queens, but the owners know a Pablo car has been tested on a full-size 1/24 commercial wood track to my satisfaction.
 
Some day they may have "P" arms, who knows? I'd have to ramp up my arm game considerably, and I doubt the winds would look surgical like yours. But they'd perform OK, I hope. :)  If they didn't they simply wouldn't leave the Ranch. ^_^
