Power hacksaw - video

[yair feldmann]

So, why do I need a power hacksaw? What is is better at than other options?

The best answer I can think of is the challenge of designing and building it.

Please see here my version, using 12V car wiper-motor, and a ratchet wheel to gradually press down the blade frame. The saw is mounted on a ball bearing drawer runner slide. The WiFi symbol is there only because I used a hotel door-key to activate the ratchet... A micro switch cuts the power when the cut is finished, here a 8 mm steel rod.
