Cutting Tools for Aircraft Tubing

Most projects include some amount of 4130 steel tubing. One of the most economical methods to cut tubing is the hacksaw. A bench grinder may be used to curve the edges to mate for welding. If you have a lot of tubing work there are regular tubing jigs available that will drill and cut the tubing at different angles in one operation. This is one of the fastest ways to cut and prepare the steel tubing for welding. Another economical method, which I generally use, is a fiber blade steel cutoff saw. I finish the end using an air grinder to mate the surfaces before welding.
