I've never seen anyone look for ways to put a mile of extra weld on a roll cage before, It's your business but you will never be able to work for yourself full time doing all this unnecessary work, you won't be able to charge accordingly for the time spent on a project.Most welders aren't very good fabricators, you just have to figure out which you want to be.And all those joints everywhere instead of bent bars, or the solid bars in the roof is terrible from an engineering stand point.I will leave you alone and let you get after it after this post, you've got enough going on already, just something to think on

There is a reason you don't see mitered joints instead of bends in the cage portion of a chassis/roll cage. The bends help absorb energy through flex. Mitered joints are strong, but they don't flex or absorb energy as well as a bend. You are one hell of a welder in terms of being able to lay down a nice bead, but I think you still have a lot to learn in terms of knowing how the heat from your weld affects the material. To most passer-by's, the large weave welds make it look like you had horrible fit-up on your notches, and had to run several passes to fill in the gaps even if you really didn't. There are only a few companies pushing this large weave style weld on thin material in the trophy truck world (Camburg comes to mind) and even then, your weld is only as strong as the weakest material being welded. If the joint is going to fail, its most likely going to do it beside the weld, in the HAZ anyways.

And take it from somebody who is in this business, you will never turn a profit building cages like that, unless your customer has money to burn and is paying by the hour. Focus on simple, clean designs that can be built quickly and are strong. It is the small details and appearance of your welds that will sell your work.

Well said sir.

I think everyone that has said, I need to build a simple production cage is spot on.... I'm sure it will happen, along with many other future production designs. It's just not the intent with this particular build.

What in the Sam Hill is going on with that dash?

Why not finish the cage first?

Yeah I figured that, just odd looking and seems like one bad bounce and the dash will get punched hard.

I'll keep watching this every so often to see how his progress keeps going.

I'll guess its a cooler that will have a 3-D snake painted onto it after he spends hours tig welding it so it looks like real scales. :flipoff1:

Just admit it, you are building a fawking ironman suit.........i totally respect that, badass.
