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

Hello, did you happen to make a public version to download? Would be a big help, doesn't matter if it isn't finished yet. Thanks

hi greg, great video!! i came across this as i'm trying to draw up a sequential dogbox model in fusion 360 which i'm going to 3d print, but i'm having trouble modelling the shift paths on the shift drum, can we talk through email or somewhere where i can attach files?

[@gregbrown-onshape7555]

I'll see if I can clean up the shift drum and make a follow up for it - there's certainly some interesting modeling in there!!

[@lenardchang743]

thank you very much :)@@gregbrown-onshape7555

Hello Greg. Nice work. Can you offer any advice or direct me to any Onshape tutorials for how to model the gear teeth and selector parts?

[@gregbrown-onshape7555]

Thanks for the suggestion - I can dig one more level into this model if you like and show you how I did the teeth and selectors. Stay tuned...

[@sankaran1382]

i want the link for this design

[@gregbrown-onshape7555]

I'll see if I can clean it up and make a public version...

What kind of bike is this from? triumph?

[@gregbrown-onshape7555]

Although I have owned Triumph bikes (Street Triple 675, Tiger 1050) in my past.... this one is in fact from my Suzuki RGV250. I have a couple of spare engines hanging around so it was convenient to pull apart and take some measurements!

2-stroke? can you ride it on the street or is it track only?@@gregbrown-onshape7555
