I need to form some 10mm round bar and 20x3mm flat bar for a garden arch with a radius of 1m, doesn't need to be super accurate, just repeatable. I don't have access to a ring roller and can't afford one which will roll 10mm round bar. I've seen people forming round a ply template but for one arch the ply would cost a fair bit.
Would it be possible to use 5 or so pieces of 2x4 or similar around the radius to bend it round?
Also how much smaller roughly does the former need to be to account for the spring back?
