Too job, both Peter and Rowdy. Rowdy, you're an old man mate - you should be sleeping at that time of night!
I'll try to take a pic of my 'knock out block' later. Nowhere near as posh as yours Peter, but it does the job. As you say, the first one is a pain but after that they get easier.
I just got to many ideas running through the old grey matter aint got time to sleep.....
