Can anyone tell me what the black thing of a ma jig is on the early HB model?

G'day Russ.It's an insulated support for the brush holder connection or switch slide (top and bottom)It has a copper ribbed section to told the brush holder in position and maintain power to the brushes as you adjust the  speed.Sorry for the poor image but I hope it gives you the gist of it.
Cheers j

Another shot.. The insulated black disk on the back side of the brush assembly has a brass clamp that  supports  the brush holders.The opposite side of the clamp makes contact ribbed conductive slide..allowing power to the brushes
if that makes any sense :wondering:

So basically, the black "round peg" sticking up through the top of the motor's housing is just a locating tab to help keep the position of the insulating disk?

Thanks for the black thing of a ma jig report gentlemen.  And we will all give Mr. Kearns an "E" for effort.  :clap:


So far I am aware 5 owners of this early model.  It appears David Dimitrion has the title for the earliest serial for this 12-15 model?  Anyone out there with and earlier serial? :wondering:

G'day David. The black pegs holds the curved wavy conductive plates that puts power to the brush holder. The Black insulated disk is on the back side and moves with the brush holders. I haven't taken mine apart...as you can see by its filthy original state:shock: but the black insulated disk must be held central by the rear motor housing.
