Michael at least you had go, that's what matters really, and more importantly you know your limitation as to what can be achieved personally. I think Andrew could have fixed it and I would have had a good go, maybe taking longer to complete, they are complex machines, and finely tuned to make all those plates spin at the same time. Well done for have a go, I will always help someone who's willing to at least try......

To your last line above there Paul,...precisely the right outlook and attitude that our hobby and forums depend upon nowadays!
Very well said Sir!!
