This one started as a Russkit "22", and the end bell (in my best Maurice Chevalier..."but of course mes ami!") got tossed.  Can got stripped and painted gloss light blue and the el-junko can bushing replaced by a 5mm x 2mm bearing.  For a new end bell, I used one from a Hong Kong produced Mabuchi FT160.  These are both "genuine Mabuchi" product, and at this stage definitely "vintage".  While they look sort of like a cross between a Mabuchi FT16D and Champion end bells, these things are made from an extremely tough, durable and heat-resistant material...seemingly as tough as any modern end bell, maybe tougher?  I removed the stock sintered metal (magnetic/iron content) bushing, machined a reducer and epoxied-in a 5mm x 2mm  bearing up there as well.  Lastly, I trimmed the edges of the end bell so it's not proud of the can (*the HK Mabuchi has a MUCH thicker can metal).  Lastly, I drilled top and bottom inspection/cooling holes and dyed the end bell purple.

 

I had one of the Mura can-in-a-can shims and epoxied that, along with a set of really stout ceramics (after a fresh zap, they measure over 1300, about the top on my meter for ceramic singles).  By removing the shim's internal clips, I wound up with about a .535 "hole".

Like I said, these end bells are tough as nails.  No real bulletproofing is needed here, although I will install post sleeves just to increase the posts' OD to better fit the springs.  For an arm, I built a .460 stack and wound it 38/27R.

Now that's really nicerer than nice...

Thanks guys.  As I've said, these cans make for really good motors...even for "modern ones".  The only strong magnets that work for these without a shim are the modern ones, and those work best with a .560" diameter arm, so there's always a choice to be made...no shim/larger arm, shim/smaller arm.  The HK Mabuchi end bell is THE answer that came too late for these old motors, but at least there are some of them left.  When I first "discovered" them, I got some, but my supply is getting pretty low.  Put the right combination of parts together, and you can build/wind a real screamer and not have to go through all kinds of "improvements" that would still often result in catastrophic failure.

sharp as a tack!!!  fundamentally group 27 right

 

but if group 27s are faster today than yesterday musnt cl double 27 must be outa sight?

Id love to see a d 27 look that neat,and someone put up a video or audio of the scream that was so memorable ,especially going into the bank of the blue king!

I have done double #27 winds Bruce, but what would that have to do with a single?  BTW, a double #27 is pretty much a useless armature, being roughly equivalent to a #24 single.  I've done #24 singles as well, and those are pretty much useless also...except maybe as a conversation piece.  If you pay me, I'll make you one of either and you can have it mounted to wear as a necklace. 

(*edited, I originally said that a double #27 was equivalent to a single #23, when it's equivalent to a single #24)

Hi John,

 

Yes, but I can't seem to stop building necklace bling, maybe some professional help might be in order...

I make many many really big wire arms also Geary, and many go to repeat customers who I'm confident know what to do with them.  In terms of "racing", I seriously doubt anyone has much use (*other than drags) for a #23 or even a #24 wire arm.  Even though I believe that doublewinds *may* have a real value for slots, I don't think anyone actually races those either, although I've done many of those as well as triples and even a few quads.

The arm is done and ready to go out with the next group of arms to Bill Bugenis for grind/balance.  Resistance comes in at exactly .158 ohms per pole on this "long-ish" .460" stack.  This motor will be a runner for sure.  Team Russkit could have done some real damage with this bad boy

[havlicek]

Oh and, I should mention (because I made up the wind AND the designation) that the "R" in the 38/27R means "reverse wound".   So, it's really just a "me" thing.

 When that motor was new Team Russkit did not have a controller that could handle this much motor. 

 

Beautiful motor John.

great idea,but if it becomes a fashion craze and makes millions will you expect more than your regular armature fee?

Thanks Eddie.  In the race for more speed, the controller folks would have figured something out!

[boxerdog]

You know, that is absolutely right. One thing I do recall about slot racing in the sixties was that something was always melting...endbells, arms, controllers. Pretty exciting for a few years!
