"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.

Richard,
     Your mill looks quite portable as is. Many times I've taken my folding engine crane in the car to pick heavy items up or to load them into the estate car and then loaded the crane along side so it could be used to remove the item later. I've moved various engines, welders, a floor standing bandsaw.
