wall thickness of the lambretta front down tube
Posted: Mon Oct 31, 2011 11:28 am
Hi sorry me again, has anyone got a cut up frame that they can measure the wall thickness for me, or does anyone know what guage tube is used in standard frames?
Im building mine in a different style, rather than tube Im using flat sheet, with bored and welded cross tubes, then boxed in top and bottom
my first thought was 5mm, but wondering if that might be overdoing it?
the sample pieces are cut from 3mm and work very well, so do I go with 3mm?? or belt and braces but nearly double the weight??
risk of it resembling a battle ship with the way I do things LOL
