I wanted a tube notcher for a while. Cheap ones aren't good, good ones aren't cheap. Went through my odds and ends pile and found a pieces of 1.375" shaft and 3" X .250" wall tube. $10 for bearing that would make the 2 work together. A "V" block from a machine shop exercise and some other scraps. A little lathe time and fired up the welder. Even painted it.
