I never seen a balance job like this.

Most likely the balancer drilled the lightest pole first and tried to compensate for the other 2 poles.

 

Another  "THINGIE" history oddity 

        FRENCH 36D

(Armature pole numbers 1 thru 3 by me)

Pretty funny Gene... kind of looks like an aftermarket job! 

 

I had a few of those French arms in the box and they were all pretty clean.

Is that balancing or a shotgun blast?

I wonder if much of he epoxy flowed to the can end of the arm while drying & that's what all the drilling was trying to compensate for? My Champion grind balanced arms of that era didn't look this bad, but neither did my one French bought in 1968.

Were any of the others anything like this one Gene? 

 

You wouldn't think that they'd let this one off the assembly line!

They look like were done by an old time balancer (name withheld as they may still be alive) that Bob Green referred to as a "Butcher". The free balance race prizes were often discarded on the track floor. This has to be among the worst looking balancing I've ever seen, a bad day at the shop.

Quickly looked through 7 factory cases (84 arms). one plastic box had 2 each arms, the rest have 1 each

A few have no balance marks.

Was there ever a French product\parts listing sheet? 

Parts FM137 have gray comms and FM138 have brown comms.

Part FM137 have gray comms

This arm has not been put on the lath polished and comm trued yet.

You haven't lived until you had to dremel the corners off the stacks because you ran out of balancing room for drilling. . .

As riddled with drill holes as it is, it has every appearance of being a French arm, in my opinion.

 

I know early Champion, Mura, Lenz, and French used Tradeship comms for a short period of time before the Kirkwoods became the comm of choice for many years. Tradeship made 16D/26D and 36D comms in 3 different timing cuts in both CW and CCW directions. They were 0°, 11° and 22°. 0° comms were either brown or black. 11° comms were usually gray and 22° comms were brown. 

 

I have a few of some of those comms NOS I have picked up here and there. Most of mine however are CW direction. I guess most of the CCW ones got used up back in the day or hoarded up in people's stashes.

 

Someone on ebay is still selling ones he got somewhere. They are brown with a 22° CW cut and fit .078" shaft.

 

https://www.ebay.com...ommutators.TRS0

 

His ebay ad says 0 degree timing. The ones I got from him were 22 degree CW. The ones he shows in his pictures are 22 degrees CW.

 

FOAMY SAID:

"You haven't lived until you had to dremel the corners off the stacks because you ran out of balancing room for drilling. . ."

 

Well, Dennis, I guess I have lived. I haven't had to do it much, but I have done that a few times  :good:
