Understanding a motorcycle gearbox is easier in CAD

Join me behind the scenes for another of my single-take rehearsals for demos that I am prepping for, test-driving new concepts, or generally practicing. Usually recorded late after all my normal work is done, you might enjoy some of the tips and tricks I hope to offer.

In this session... I look at one of my favorite little assemblies I use all the time for demos: a motorcycle gearbox cassette. This is the typical 6 speed sequential shifting design (I reverse engineered this from my own track bike which is a classic Suzuki RGV250 2-stroke race replica)

Of interest is the use of named positions, but the focus is on the External thread feature and how it is represented in a quick 2D drawing
