Hand planes might just be the most used tool in the hand tool shop. We use them to face rough sawn lumber, we use them for joinery and we use them for moldings. While there are plenty of new planes out there that are just about ready to go out of the box, you still need to understand how they work and why they work well or don’t work at all. The best way to understand how a plane functions is to get an old one, take it apart and tune it up. Even if you buy a new, premium tool as a bench mark for performance, it’s still helpful to clean up and tune up an oldy but goody to better understand what kind of things can impact their performance. That’s exactly what we do in today’s episode.
