Thanks Gadge, I didn't get involved with the deck, pulley setup on the Anniversary one I had last year, this had all been replaced by the previous owner just before he gave up on it. The diagram is good and this will now allow me to sleep at night. I wonder how many sleepless nights old Mr Greenfield had staring at the ceiling trying to work out how to make it work. Same with the drive clutch wheels, always grabs my attention when I see the 2 wheels side by side on a single shaft with them turning in opposite directions. Thanks again that cleared that up
