steeky147
all rims would be formed in that same way and the thing was that the metal was very thin as it's stretched out to form the rim..i think [could be wrong] the rung that broke on you steeky147 is a 1 piece rung right thru the stiles but that is squashed in a press to form those rims you describe. but if you bend aluminium to 180 degrees it is very brittle at the bend point .
