I have dismantled the drill to the best of my ability.
Due to cost reasons, I am going to use Evapo-Rust for the smaller parts. I will try “The Works” toilet bowl cleaner which has been mentioned by Chris Schwarz and Wood Talk Online. I am curious to see how “The Works”, works, since I have never tried it. Evapo- Rust is great and always works well, but getting enough to soak a huge part is too expensive.
Maybe I should make a video to show how or how not to use the works to remove rust, since this is becoming a hot topic. Stay tuned.
