I designed and built my bumpers/suspension/crossmembers/rollbar/rockerguards/etc mostly with just a 4.5" grinder and a drill. I only paid a pro to do the welding and the tube bending. Maybe in the future I'll get a nice welder.
I'm just sayin', don't let the lack of welder keep you from the fun of Jeep building. :thumbsup: Start small, build up your confidence and tool collection, and you'll be well on your way to tackling the tough stuff. :clapping:
