Ah so you're the guy made it, pretty nice job though i would suggest finding some more parts to get that base or drum. No offence but i think you look like a hippy lol.
If you find a bigger motor that is of lower RPM you could get a much lower tone and maybe retrofitting an assembly line for some drums and other sounds.
He could actually hack the washing machine to control the tub rotation. If you add a weight to one side of the tub to off balance it, I bet you could make a nice bass sound.
I'd add some relays too, for a little extra percussion!
