Explaining Undercut in Spur Gears

Than you!

Thanks It's a good explanation ☺

Should it be "increasing the distance between center points of two gears? Im confused.

I imagine the undercuts aren't designed to bear pressure from the meshing teeth. If so, why wouldn't the tooth tips simply be shortened to avoid the interference? I assume the tooth would only gain strength by following that approach.

This video needs a remake. There are times when it sounds like you talking to yourself and not the listener (4:30 to 4:50). At time point 4:50 your explanation needs a graphic showing two meshing involute gears. In the current version this section was to difficult to understand. I stopped listening at this point because I could not follow your explanation. I'm 65 and familiar with gears but I don't know a lot about them and wanted to learn more. I'm sure making videos is not easy, even teaching a subject can be a challenge.
