How to make a gear box using worm gears, part 3.

I made a video showing how I used a gear box that uses worm gears to power up a weak rechargeable drill. Using a gear box, you can even jack up cars. The rechargeable drill I'm currently using is a very old model with specs: voltage 4.8V, capacity 1.2Ah, and rotation speed 460rpm. →The latest drills have higher voltage, capacity, rotation speed, and torque. I think you can get better results if you use them.
The videos are in a series and are a bit long, but if you're interested, please take a look.
Sequels are planned to be released one after another.
