Austin, you are correct, the 12lb tub was used in the '63-'64 Multimatic, as well as the '64-69 Rollermatic. What I meant was the tub I'm using in the Super Unimatic actually came out of a late 60's Rollermatic machine.
As for the Recirculation Flume a Kenmore or Maytag fill flume sprays the water outward in a circular fashion. What I really want is a fan like high-pressure spray, like the fill in the '59 Philco or the Spray in the Whirlpool/Kenmore Combo, but with higher pressure. The reason I want this is mainly for the "4 Minutes of Magic" cycle with will spray a high concentration of water/detergent on the clothes as they are spun, similar to the Kenmore Catalyst cycle. I'm going to get the tub up to full 1140rpm and then cut the motor but leave the brake solenoid energized so the tub will simply be coasting from 1140rpm down. I want the fan spray to be aimed at the right side of the tub as to help push the tub along and help it coast clockwise with the spray. Also a fan style spray will help reach the entire sidewall of the spinning washing tub from just under the top rim all the way down to the bottom.
(1) Since the tub is wider, might there be more of a chance of the tub hitting the cabinet when starting to spin, before the load balances out? Would the window be at risk of getting broken?
Peter, the WO-65 cabinet is 25" wide, the outer tub in the Rollermatic machines is about 25.5" so while it might hit the side; it won’t hit it with much force. I did put a piece of rubber at the top of the window where the tub might strike it just in case. In "phase 2" I'm to teach the Super Unimatic how to communicate with the computer so I'm going to install an unbalance switch that will tell computer there is an unbalance load, but I probably will program the software to only stop the machine if the sensor is hit more than once. But that will come later.
(2) Would the same flume be used for filling and recirculation?
No, 3 separate flumes. One to fill the outer tub with fresh water (wash fill), one to fill the inner tub with fresh water (rinse fill) and one to recirculate a fan spray. Hey I like your idea about the 1/18 Circle Spray I didn't think of that! That might make a perfect inner tub fill flume; I can make one out of flexible rubber hose. Thanks good idea!
That's also not a bad idea about having the filter screen inside the agitator column, since there will be a separate detergent dispenser. But I do want a fan spray for the initial “Four Minutes of Magic”, but maybe I can use a diverter valve and spray the recirculation water during agitation into the center of the agitator, through a screen. More to think about.
