What a unique treat that was
Side mounting seems to give the best of both worlds, up down, back forth, and around. That is the most versatile impeller I've seen with the most original water current patterns. At first, it looked as if you did not load up many items, but as you sluiced them over to the spinner, I see you had a nice size load in there.
And the second load--wow!--that was a monster, what we call a Bobload after our friend Appnut.
Kic, you really like washers, playing with the controls, switching them back and forth, moving the hose up and down, but real give away was rinsing out the tub with the impeller on. Sweet. Great fun! You're not alone.
Couldn't tell if the gentle speed was a shorter stroke or a slower one.
Can hardly wait to have my socks blown off, speaking of which, I see you're in flip-flops. What's the temp down there?
