i have a question regarding the best way to scribe my miter lines at various angles; where the down tube connects to the head tube for example. i am GTAW welding a steel frame, so i can use the inside of a lug to get my miter lines.
Any suggestion would be helpful
tubemiter.exe is a Windows program that prints miter patterns that are then taped to the end of the tube to mark the miter lines. Inputs are miter angle, wall thickness of tube being mitered, and tubing diameters of both the mitered tube and the mating tube.
