Thanks Terry,

That's easy enough to do.

Overall, from the feedback so far, maybe this wasn't the best circuit to have stumbled across?

Something that occupied my time indoors when it was too cold to be outdoors jet-washing my drive and patio.

All done now that the sun has got his hat on! (Good fun - I think I must have been deprived of water pistols as a child).
