Header tank planning

Did some initial planning on the header tank today.  We will be fabricating the header tank using a 1/8 inch thick aluminum tube that is 6" inner diameter.  We wanted between 2 and 2.5 gallons, so settled on a tank length of 19" which will fit nicely on a vertical support behind passenger seat and give us a capacity of about 2.3 gallons.  We cut the tube to length as shown in the picture, and the left-over piece will give me the opportunity to practice up TIG welding before making the real tank.  The bandsaw did not have the height capacity to cut the tube in one pass, so we fed the tube part way, and then rotated it slowly to finish the cut.  This worked great as we got a nice straight at the end of the tube.  Hours: 1.0
