As the channel name implies, [Workshop From Scratch] is building a growing list of tools and machines from scratch. His latest edition is a heavy-duty metal band saw.
As with all his tools, the frame consists of thick welded steel components. The blade runs on a pair of modified belt pulleys and is driven by a motor with a worm gearbox. The blade tension is adjustable, and so are the pair of blade guides. To slowly lower the blade while cutting, [Workshop From Scratch] added a hydraulic piston with an adjustable valve to limit the lowering speed. When it reaches the bottom, a limit switch turns off the motor. The saw is mounted on a heavy steel table and can rotate at the base to cut at different angles. A heavy-duty vise, also built from scratch holds the workpieces securely in place.
Judging by the amount of steel he cuts for his projects, we imagine this saw will be a welcome addition to the shop. It’s impressive what he is able to build with just a drill, angle grinder, and welder. Many of the other tools used in the video, like the magnetic drill press and hydraulic vise are also his handiwork.
