This is my first time on the forum , I have a few questions if I may ask ? can a dragster be built with mild steel tubing?, is it legal in the states ?Can it be certified ?Chrome moly tubing is expensive and I don't have a tig welding outfit however I do have a mig and reg arc welders , my mig I can set it up for steel, stainless steel, and aluminum welding I have a milling machine and lathe and laying out in the yard I have 4 20 foot I beams I could use for a jig to build a chassis on .I do know some door slammers use a mild steel chassis but not sure about a dragster or maybe an altered.
