thank you very much gentlemen. I'm sorry about the links to the pictures - for some reason, I can't seem to get the pictures to show - no matter what type of URL type I try. I'm usually pretty OK with that sort of thing but in this instance it would appear that I'm not. I'll have another play with it shortly
If your interested to see more, I have got a complete build log here if you would like to see how it went together :

thank you again for your comments and I'll try to fix those pictures
Kind regards
Simon
