Is this a Globe, a Wilson, or ???

 

As found, with bracket and nice screws... I have not opened it or put power to it.

 

BBs in both ends, feels like it has great magnets.

 

Any suggestions?

 

Thanks.

1/8" shaft ?

 

I know Globe's were.

 

Not sure about Wilson's.

 

I have a car of Geary Gaspord's at the shop, with a Wilson, but I never looked at it that close. 

 

FWiW, the pinion end of that shaft is really crisply trimmed.

 

It looks real professional.  

 

But IMO, it seems like a lot of effort was made for something not very conducive to installing, a solder or press on, pinion.*

 

The opposite end has a very factory/professional chamfer.

 

*PS- in retrospect I guess maybe not a real big deal if it used a set-screw pinion.

What's the armature shaft diameter? It looks awfully big...

We posted at the same time.
 
See post #2. LOL.

[Cheater]

Great minds think alike.

Or is it sick minds? I'm not sure... LOL!

[Champion 507]

Greg, in your case it's... never mind.
 
Motor looks like a Globe to me but I've never owned one, so I'm not sure.
 
Hey, Dokk, some help over here, please?

[Gator Bob]

1/8" shaft, .91" dia. can, 1.265" long (can and endbell).
 
Now that I look in the Wilson's dealer gear kit* some motors might be eliminated as a possibility.
This motor is designed to last that's for sure.

Looks like a Globe SS-91 to me.

 

Mike, Gary's car has a Globe SS-91 in it (If it's that red Manta Ray).

[Gator Bob]

Thanks, Dave.

 

If it is that is cool because as a young kid I remember going to a track named Grand Prix (later called Highway Hobby House) on Rt.17 in Upper Saddle River, NJ and the hot dogs were buzzbombing that track with Globe motors.

 

I think the 36D's had just come out around that time. 1963-64?

[don.siegel]

Bob,
 
Definitely a Globe SS-91 Screamer (or maybe an SS-81, which was their 18-volt version of this motor, but they seem to be a lot rarer - in any case, same can, just different winding).
 
They had printing on the can to show the brand and model number, a couple different versions, but these often wore off over the years...
 
The SS-91 was first advertised in 1964, at $14.95 - three times as much as a normal car at the time!
 
I only remember seeing one in my local hobby shop at the time, on the dragstrip, but I still remember the sound of that motor winding up on the strip!

The Wilsons if I remember correctly had plastic endbells. I had a Wilson; it was the poor man's Globe.

[Bill from NH]

In addition to the plastic endbells, my Wilson has a 3/32" arm shaft rather than 1/8".

Here's a pic snagged from a closed eBay sale that shows the printing that would have originally been on the motor.

Is this a Globe, a Wilson, or ???

 

That's a standard, well-used, SS-81 or SS-91 (the markings being gone, it is impossible to tell). The terminals look like they have been butchered...

[don.siegel]

No, I think those are the regular terminals - wasn't a lot of meat on there to begin with!

 

Greg, thanks for that shot; that shows what I think is the more common label; it was possible the earlier one that just had a big "SS91" printed on the can, and maybe Globe too, can't remember offhand.

Don, the terminals were just like the ones on an FK today, a small blade with a small hole to stick a lead wire in it. The ones on that motor look buried in solder and likely, bits of wire, and you can see the burn marks on the endbell... that is what I mean by "butchered". I have very tight standards as far as soldering lead wires, some would even call me "stuck up"...

And frankly, they might be right!
 
But those are MY standards.

Here's a  SS-81:

"They All Look The Same To Me"...

[Gator Bob]

Greg and Pekka, Thanks for the pictures.

Looks like the screws are correct as shown in the picture Pekka has posted. These motors are like 60s aerospace quality.

It looks like the part number for the SS-81 was a - (dash) something, Pekka is it a -18...like... for the voltage? Do you know if those hex (Allen) head screws are original to the motor?

 

Think I remember that ad in the magazine, didn't it have an XKE Coupe in the picture? Don't ask me the color of the car in the ad .... lol

At $14.95 they were more then I could earn in 3 weeks to a month on my paper route of 50 +/- homes.

 

I will disassemble for cleaning and inspection ..... Does anyone know if it was more turns, smaller wire or both that set the 'voltage' rating?

 

Is this brass motor bracket unique to these, I have an NOS in-line Dynamic bracket for it.

 

Any suggestions on a good application ... Drag car, maybe....?

 

Mike, what is the car Geary has built up?

 

Dokk, you pooh-poo about 'many' things slot that members post. Don't ask me 'how many'.

I'll clean the terminals, I think they (are or) will be just fine.

So then..... if You can't tell what it is I will call it a Screamer ! To compare anything on a Globe to an FK is a total joke.

 

Thanks to all those that contributed something positive to this question of ID.

Bob,

I've never messed with a Globe but the word on the street is that these motors are VERY difficult to re-assemble and thus disassembly is considered something best avoided

PdL can advise, I'm sure.

[MSwiss]

Yeah, that's it.
 
I have no idea why I thought it was a Wilson.
 

Mike, what is the car Geary has built up?

 

Like Sano Dave mentioned, it's in a red Manta Ray.
 
FWIW, it has a 20t set screw pinion.

[Bill from NH]

Bob, put it in a car that doesn't need brakes. I've got one squirreled away for a special application too, maybe for a brass rod 4.5" stock car.

There are two issues with the SS-81/SS-91 motors:

 

1) If you remove the armature, the Alnico mag loses much of its charge according to period literature by Globe.

2) if you disassemble the motor, putting the brush springs back requires an amount of patience that will test the most relaxed person on the planet. because there is no enclosed channel to retain the brushes, they keep popping up as you try to wind the funny hairpin-style springs. Best is to make a little circular fixture to "lock the brushes, and once done with fitting the springs, gently insert the factory retainer and keep it there while re-assembling the mess... good luck.

3) Gearing

Because of the 1/8" shaft, the motor cannot be geared correctly because you cannot find a pinion small enough to gear it right, that will fit over the shaft. Two solutions to this:

- Use an 11t 64P pinion about 1/4" wide and machine a 1/8" hole in half its thickness. This will allow the pinion to fit over the shaft while retaining enough strength once soldered over the motor shaft. See illustration below over the 1/8" shaft of an SS-101 that uses the same armature:

 

 

Be very careful as there is almost no metal left under the teeth! For example, if you try this with a 10t pinion, there is not enough material for drilling the 1/8" hole.

- Find an older Weldun or Tradeship setscrew pinion, 48 or 64P, with the smallest number of teeth you can find.

 

After that, depending on if you are using a sidewinder or inline config, find the largest gear that your tires can support, giving you enough tire wear.

Then you will find that the motor is extremely fast for its era and has tremendous brakes. The issue I found with the little Ferrari 330P4 I built with that motor is that the Cox-based chassis was grossly unable to handle the power... so i parked the little beast for good exactly... ten years ago.

 

 

 

 

As I am going to unload my own vintage and Retro cars pretty soon as I am basically done with slot cars, don't be surprised if you see it on ePay before too long as well as all my other cars, controllers, motors, chassis, you name it! 

[don.siegel]

Actually, for scale cars, it's not much of a stretch: a 10 tooth pinion and a 50 tooth spur gear, easy to find, and that will fit 1/1/8" tires - that will give you some brakes, but it still won't stop on a dime! According to a friend who's had a few of these, most don't have brakes, but occasionally one does! I did have one rezapped by a great guy in Calif, but now I'm not sure which one it is... 

 

I still have at least two of these in pieces, and haven't had the courage to try to get them back together! And I took apart my SS-101 in 1968, thinking to rewind it - and all that's left is the ball bearings! Never did get around to that...

Don,

The one I had did have great brakes once geared properly. The SS-101 brakes like a GE, like, right now!
