Fantastic Graham! The big spirals on the left are interesting, what are they made from? Maybe it's time for another ball roller but it certainly won't be this one! ( I hope you can guess my true identity!)
Ha! Of course, Bert :) The large diameter spirals are Channel Segments joined and sprung slightly to make that spiral, about 16 of them as there seem to be two full circles of them (8 to a circle). The troublesome part was the elevator in the centre. That took some time (a year or two on and off) to sort out to make reliable in capturing the balls at the bottom, and then discharging them at the top.

Fascinating device!
Thankyou, Catherine. I'm pleased you like it! It had a long life and was shown at many Meccano shows.
Magnificent Graham.
Thanks Baldy. It had a good innings, being shown at many Meccano gatherings over the years .
I like it 👍👍
Thankyou, Georg. I should have retaken the video before dismantling. It's OK, but that;s all :(
