Saw a couple of guys weld a new frame for a car on Spike TV power block. the actual cutting and welding of the frame looks easy, if you have the skills, but the actual transfering of the rest ofthe car onto the new frame looks like it might be a royal pain in the ass. Host of the show havent gotten that far yet so I havent seen the finished product. Just wondering if anyone had done it before.

im guessing they're fabricating a frame from scratch, the actual cutting and welding if you have done it before you can get by, but no way easy. like cuts using a band saw, chop saw, oxy, plasma, etc. all have different things to be keep an eye out for. welding done easier with a mig but tig is much harder but if you know how to tig, you get a better product. the precision measuring, compensating for kerf, figuring stress points into certain areas, and drawing templates to transfer onto metal is the hard part. it's a show, and they literally fit a 5hour process in 2 minutes. if building a competition frame as in a tube chassis or something they have to keep everything within the rules of the sanctioning body of the racing event the car is intended for. outside dia. of tubing, thickness of material, a certain kind of metal, tubes in their regulated locations, etc. just a few things checked for before racing.

tube bending is definitely difficult. making sure size of tubing, figuring how much ft to use, get right dies, marking tangent lines, finding cl, etc. one thing off and your f'ed. been fabricating stuff for a bender for a bit longer than a week now, cant wait
