Do you have a welder? If not nows a good a time as any to buy one and learn how to weld and build one yourself. It was the 4x4IRON bumper that prompted my to buy a bender and build my own. I wanted to buy one back when they were in bussiness but I just could not get past shelling out $675 I believe at the time for a bumper. I thought I could buy a bender and notcher and build a hundred if I wanted to. I had a welder already, so that is exactly what I did.
I bought a bender and notcher, now I have built a bad ass bumper, two bad ass cage, one for my bud Suzuki Samuri one for my K5. So I actually thank 4x4IRON for inspiring me to learn more and get more into fabrication then what I already was. Learning the skill of bending tube has been so much fun, that skill is an awesome skill to have. If you dont have a welder, instead of buying a bumper, I would buy a welder, buy some steel and go to town. Ask help from someone you know that know how to weld already. MIG welding is the easiest welding there is.
To me if you can draw a series of evenly spaced symetrical curly cues or basically circles that overlap and circle back on each other by about 1/2 the circle diameter you can weld. Sure there is a learning curve but it ain't that hard. Read, ask questions and in no time your welds will be very good. The hard part of fabrication in the Engineering and Design. Some guys just don't get it and never will. The things we see from time to time posted is horrifying, and I would not want to be driving with my family in a car next to them with their death trap. JUST because a person knows how to weld does not make a good fabricator.
Thats the harder part to learn. Learning how to build something with good triangulation, structure, what ever is necessary to make it safe and then looks come into play too depending on what your building. Weight is a factor too. I build overkill and I know it, BUT not too overkill. I fell my stuff is pretty damn built tough, looks good, and is funtional.
I say buy the tools and expand your mind & skills man.
