Bill......

I see how you did the box. Are you just using the rags in the first pic to try and make a good seal between PN & cardboard? I see like a false back inside?


 


<a name="start_33360.364042"></a>What color is the Model G that your mother-in-law gave you and your wife? Electrolux changed the Model G color from aquamarine green to tan in 1966 to indicate that the motor had been tweaked to give it higher rpms (the armature was wound with more copper and more commutator segments). A quick way to tell the difference (if a motor had been swapped out at some point) is that the aquas' motors had black brush holders, and the tans' motors had burgundy ones. Another reason for the color change was likely to differentiate the more durable plastic used in the brown-colored wheels than the teal ones. It's definitely more common to see broken teal wheels than brown ones.


 


Fred; Ours was the aquamarine green, or what I always called 'turquoise' or Jetson Green. I remember that now on the motors of the G....been some yrs since anyone has said that. I don't remember the brush holder colors offhand. I bet anything it's the later motor that wound up in there, though not from my doing. I didn't realize they made any attempt to make the wheels stronger on the tan G. I never even noticed the wheels were different diameters from front to back until I broke all of them. Was playing around with my dawgs and fell...well, more like a Swan Dive right onto the center of the vac.


 


<a name="start_33360.364042"></a>Aerus (and perhaps aftermarket companies) makes brush strips with cut-outs that minimize the collection of contaminants at the edge of the bristles. Consider swapping out your standard ones for those (the brush plate needs to be removed first, then the metal grips are bent back with a flat screwdriver or knife to remove the brush strips).


 


I'll start looking around. That configuration makes a lot of sense as you explain it. I have plenty of original floor brushes, so I can certainly treat myself to one that is highly functional with bristles.

Kevin,

I used a high-end microfiber cloth to ensure a good seal just in the front of the rug plate. I have seen other manufacturers on YouTube use them (i.e. Dyson).

The "false back" you *thought* you saw was actually some 2x4's used to prevent cardboard box droop when testing machines over 16 lbs. So all the Kirbys needed them...

At some point, I will rebuild the same airflow box, but instead from cardboard, I'll use wood so I can test water lift from the power nozzle. My cardboard one definitely couldn't withstand any sealed suction tests as it would implode.

Bill,

On a second look-see the wood stiffener was apparent. Maybe like you say...when I build the box I'll do it in wood for a final version. Thanks!
