Made this during the corona virus shutdown. The base is a discarded quadriceps weight lifting machine, the black part. The rest is small scrap steel pieces I had lying around. The saw handle is supported by two hooks and is tensioned by two 1/4 inch round bars with 1/4 inch bolts welded to the ends. They go through existing holes where the seat was on the weigh lifting machine. The tool rest is a 3/8ths thick piece of aluminium which is attached to the saw. These saws are available at harbor freight currently via a coupon for $89 bucks......the blades are junk, so go to Lowe's and get the Lennox blades, cuts steel and aluminium like butt-ah.
