Occassionally I buy extruded already anodised aluminium sections from my local B&Q. What they have in stock on any day is a bit of a lottery. Does anyone know of another supplier besides B&Q and Wickes?
On the same subject, I know pre anodised sheet is available but finding a supplier for anything less than a full sheet is not easy.
Many years ago I recall ready finished sheet being sold by architectural metal suppliers, also I have been told that the control line model aircraft fraternity use thin (0.3mm 'ish) hard anodised sheet to make wings but my searches have been fruitless.
