If I can work out how to put a photo on my post, I'll put one on tonight mate .....what I need to achieve is simple though - imagine you get your spirit level and mark a straight vertical line on a wall - how do you transfer that line in exactly the same opposing position on the wall behind you ? ...normally we don't need to, we just take the horizontal round .....but In this particular case, I do need to !
