I am looking to taking on the task of building me a drag racing funny car chassis . Now the kit I am looking it has already pre bent and notched tubing. I am a complete rookie at this and been reading all the resources on this site. How hard would this be to do? Does anyone have expeirance in building a jig to do this? Any help would be great. As a rooking would the $1700 tig welder Diversion 165 be ok to use? PLEASE HELP ME!!!
