Contractor Modifies Milwaukee Hackzall Into Portable Cat6 Cable Untwister

A contractor known as Analytical Horsepower on YouTube took on a job that required making 50,000 custom Cat6 cables, resulting in 100,000 terminations. Initially, he purchased an industrial tabletop wire-straightening machine and modified it to be portable with a battery and bike pump. However, that setup proved too bulky for tight spaces. To solve this, he studied the mechanics of the machine and realized he only needed a reciprocating tool combined with a clamp. By utilizing a Milwaukee Hackzall, he was able to use its detailed data sheet and instruction manual to 3D print and laser-cut the necessary parts. The resulting handheld device successfully straightens twisted pairs in under two seconds.
