I haven't done any fab on my Jeep for a while but I haven't bought any component I can make. Best tip I can give, and it's nothing new, spend more time drawing it up and measuring than fabbing and you cant go wrong
Another tip for steel parts is to score the back to thin it out, bend the part and then weld up again, easier than cutting into individual parts and then welding together.
Anyway, couple of pics of my stuff.
Winch bar, rock sliders and roof rack.
Rear bar and carrier
Drawer system with fridge and inverter
Cheers
