Hello Sam,
No I haven't decided, we'll use your ideas and pics as a starting point though. Noel has had quite a bit of experience fitting pipes.
Did you end up joining [welding] the headers to the meggas or did you use the dinky clips and springs supplied by Swarbrick.
It seems to me that welding them into one peice would make a more solid pipe.
I see you too are a night worker. I've been doing shift work for 30 years and can't wait for the day I give it up. Meantime - bills to pay, kids to support [uni] and toys to work on
Andy
