I started building my ghetto rock sliders and have learned a few things...
Stirrups, although the right shape to make the support arms are a PITA to use because their L brackets are all over the place.
I am ridiculously bad at welding, not impressed by the finishes at all but it'll have to do for now...
Welding round tube laying on a flat surface is hard and filling that gap between the curvature and flat face is not fun.
LUCKY i had to buy a minimum of 10 lengths of this 40x40x3 2.4m steel at $3 a length so I have a few back ups
