I'm building an air cannon for firing tennis balls/potatoes/other stuff. Most tutorials on the subject are american and recommend getting pipe from hardware stores where a length of pressure rated 3" PVC pipe is around £5ish. B&Q, Homebase and Wickes are all very limited and the only place I can seem to find any similar pipe is from places like http://www.plasticpipeshop.co.uk/ where a similar pipe is £20-£30 at their shortest length.
I'm wondering if you have any experience building something similar and if you could recommend anywhere to get some pipe & fittings.
