Alan,
What is it that was said..."Rome wasn't built in a day" I rewired a very large cattle market many years ago, you think by the end of it you were on nodding terms with the cattle that came in there, it took ages. Patience and aye, deffo a holiday laddie is what is required. But, get that dod of wood fitted first
You can be a project manager, but bosses have the last word!
Only joking, honest
Iain.
