Hi Ant, steel's fine, and your right I wouldn't want the lip on the outside as it's a HSR look I'm after which is flush on the outside. As far as costs, I've no idea - and I wouldn't want to insult you!. Tell me what you'd be happy with (PM me if you don't want to voice it) I wouldn't have a clue as to the material costs never mind your time!.

Cheers

Bob.
