The sexiest of all vintage motors, Pablo, and in your good hands, bound to come out NASA-spec.

 

Build-on!

With that motor and wind, just attach a fan to the shaft and blow any hurricane away! :)

 

Cheers,

Thanks, guys. :)
 
Don't remember where I got this can, but it was true enough to pass the straightener test "no problemo."
A thin film of ATF and she went home nice and snug.

The bearing hole only needed slight reaming to perfectly accept the 6mm BB using my Goat Boy BIT.

Super Glue adheres to these endbells well (I tested it :D ) so I used it to secure the endbell ball bearing.

Endbell hardware aligned without drama and passed the "shaft drops through the brush holder tool under its own weight" test perfectly. Not usually an easy thing to achieve on a 45+ year old motor.

Nice, Pablo!  

Careful with that armature, I hear they're pretty rare.   :)

Dusted off my Goat Boy arm slugs and selected a .535" for this motor.

"Do it today before it's too late."

Yes, Pablo, how often people put things off, waiting for the "right time." Somehow I don't think that's your style. You seem to "live in the moment."

"There's no time like the present."

I think that's enough idioms for today. 😀

Magnets were a perfect fit in the can; no shims needed. A few squirts of Super Glue, done.

 

The arm OD is actually about .518", so I went with a .538" hone and a dummy "C" endbell to make a perfect hole.
