For what it's worth...Richard,

3 videos and a photo.
I've mentioned all but most recent video already here, if recall
rightly.

"Mine and mineral recent videos and pictures"

It's our local scene here in West Cornwall - interest in geology, mining
and minerals.
All are joint endeavours
Projects have been going from strength to strength.

Most recent is separating galena - lead ore - on a shaking table.
"My" rod-mill project and the rod-mill working was a necessary link in
the chain.
I've been asked if the rod-mill is portable - ie. can it be slung in a
car and taken to where there's some minerals actions? That is how far
it's gone.
The answer is yes just about - but nowhere near as much as I'd like it
to be portable. The design where the shell rolls as it will on four
wheels, two driven - enables the cylindrical shell to be put in the
passenger footwell, where it stays put hemmed-in by the small space and
balancing the car, while the frame with motor should go in the back -
maybe everything else out of the boot (truck) onto the passenger rear seats
and the frame with motor in the boot so it is restrained during travel.
Else fold-down the rear passenger seats and in it all goes.
Obviously - that the mill runs on domestic "mains" easily, within a
fraction of what our "mains" can supply (always 3kW at any socket)
and could be on the end of a 10's of metres extension lead totally
helps.

The one about about the inverter VFD (Variable Frequency Drive) drawing
1ph output variable-speed driving a 3ph motor is "the biggie" I had no
inkling of at the outset - as a readily achievable solution.

Best wishes,
