Many thanks for the kind comments gents, I have no problems with things going OT now and then, it makes for interesting discussions, and, or a good laugh. Michael, I like the idea of the competition but max size for entries is only 30 x30x30 cm. now if that was cubic meters !!!!!. Neil, in an earlier post you made on this thread you said "not an easy option for a clock build " (or words to that effect). I now know the wisdom of that statement. Stew and Alan, the cheques are in the post.
Cheers Derek.
P.S. The clock is now finished, and when a pal of mine next pays me a visit he plans on taking some GOOD photos and a vid, so for those interested keep watching this space.
