Having learned to dive late in life I made up for it in my first year by clocking up 120+ open water dives in places from the UK to Australia. I went from a non diver to a technical deco diver in 9 months and loved every second of it. Since having kids not been able to travel as much so spend my time watching videos and reminiscing, hope you enjoy my site as much as I have making it.
If you're interested in a potential mod, try a washing machine transmission coupler between the tank and the motor shaft. If the shaft and the coupling have less than perfect alignment, won't they have a tendency to become brittle due to flexing and metal fatigue? I really like your design.
I love your engineering! I'm kicking myself for tossing out a functional garage door opening motor. I recently came across a perfectly sized motor but it's a 220 VAC single phase input.
They make polishing media for that. The rocks are probably going to gouge the inside of your tank.
This process is called "TUMBLING" not rumbling.
