Cad Works Gas Tanks - Tech STC

The material was placed in a 500-ton double-action hydraulic press, and then formed utilizing a process called "Deep Draw Forming." Using the Deep Draw Forming process prevents distortion and spring back associated with other forms of stamping methods.

Once the part was formed, it was cut to size with Cad Works' six-axis Fanuc Robot. The result is a trimmed part ready to be welded.

The trimmed stampings were then turned into a complete gas tank in this process.

Each tank was welded together by an American craftsman utilizing the tungsten inert gas process. The complete gas tank was composed of three sheetmetal pieces: Left shell, right shell, and the tunnel section.

They also welded in a pop-up gas cap, petcock bung, and sunk-in mounts. After all the weld lines were grounded smooth, it gave the appearance that it was not even welded. All of the pieces used in this gas tank were made in-house.

Each tank was then pressure-tested using over 10 psi. Next, the fill holes were sealed, and then the tank was placed in a drum. (A large bucket filled with water will also work.) This is done to check for air bubbles, which could be a sign that there is a leak.

The tank was held underwater for over 10 minutes. Following that, the tank was dried and marked "passed" with the tech ID No. You don't want to have to worry about fuel leaks, especially if you have an expensive paint job.

After the tank was dried, it got one last sanding with a Scotch Brite pad and a little WD-40 to keep the rust off while the sheetmetal is being shipped.

Here you have a perfect tank for any bike build or stock replacement. Make sure that you pick the right tank and sheetmetal for your size frame: Wide tire or stock, stretch frame or stock. Check out the website for fitment measurement and opposition. All the major builders do!
