Hi GregT yes there are a few too many tubes in places buy still surprisingly light I can lift it up at either end with one hand with little effort and it has lasted this long without any major twisting or sagging so it can't be all bad. the welding looks to be mainly gas but with some TIG as well for the repairs. I am not a confident welder so I will do all the donkey work and then a friend who is a tradesman welder will do the hot stuff.
