Frame fabrication

 

The frame is extremely strong, and produced using aerospace grade 4130 CRMO steel tubes and sheets. The steel is brazed together using bronze, in a process called fillet brazing. A well-made braced joint will surpass the strength of the parent metal.

The parent metal is heated up to 900 degrees Celsius and the metal will need to glow a dull cherry red; at this point, the bronze rod and flux is applied and will melt quickly on contact with the hot parent metal. The filler is applied evenly around the parent metal joint to create a strong clean fillet.
