If you’re cutting metal in the workshop, you’re likely using a table-mounted cutoff saw, or perhaps a bandsaw for finer work. The power hacksaw is an unwieldy contraption that looks and feels very old fashioned in its operation. Despite the drawbacks inherent in the design, [Emiel] decided to build one that operates under drill power, and it came out a treat.
The build uses a basic battery powered drill as its power source. This is connected to a shaft which rotates a linkage not dissimilar to that seen on steam locomotives, but in reverse. The linkage in this case is turning the rotational motion of the drill into linear motion of the hacksaw, which moves along a metal rail, guided by a 3D printed bearing.
With a body of plywood and plastic moving parts, this might not be your tool of choice for high-volume, fast paced work. However, as [Emiel] notes, it’s faster than doing it by hand, and it was a fun build that by and large, used what was already lying around the workshop. It’s not the first time we’ve seen a powered hacksaw use 3D printed parts, either. Video after the break.
