Made a Grinder Machine Using Speedometer Cable ⚙️ | DIY Invention

In this video, I made a flexible grinder machine using a speedometer cable connected to a 775 DC motor. ⚙️
The cable works like a flexible shaft that transfers the motor’s rotation to the grinder blade, perfect for small cutting or polishing experiments.

⚙️ Materials Used:

775 DC Motor (12V–24V)

Speedometer cable (used as flexible shaft)

Grinder or drill bit

Power supply and switch
💡 Working:
When the motor runs, the speedometer cable spins fast, driving the grinder bit — making it a portable and flexible cutting tool.

⚠️ Safety Tips:

Always wear safety glasses and gloves.

Do not use for heavy metal cutting.

Avoid touching moving parts.
