Once the cut ends are free of snags, be sure to clean any oil or rust inhibitor from the tube that was applied at the factory as it can contaminate your welds. Cleaners such as Simple Green work great for this. After cleaning the tubing, mark it for bends if the piece needs bending or determine the angle of the required notch. Poly Performance uses a computer program known as Bend-Tech that takes the CAD drawing and determines the distance from the end of the tube to the start of each bend, the degrees of bend and the rotation of the tube needed to start the next bend.
