and you got a good idea though. I had that idea once. but I need many things to start. tube bender, jake press, welding equipment (which you said you had) then you need to get into the design of the whole vehicle. one tip would be design the vehicle of triangles. because triangles would be the strongest layout of the bars. then you have to make sure the bars are the right degree you want them at. then that is just the chassis. then you get into the front end. you have to either purchase spindes or machining your own. then you get into steering and where everything is going to be. and don't forget the little things you run into like header location becuase you can't just buy them off the shelf the way you want it. then you get into the rear end. you have to make sure your axle is square. im done hah

that is just the many things you have to do.

good luck and if you are serious i'll be glad to help ya out
