Default Just Another Shift Kit

There has been quite a bit of discussion about shift kits, and who designed them and who copied. None of these bike parts are patentable, but rather than copy someone else's I decided to build my own. I don't care who copies it as I don't plan on building them to sell. It is just kind of a combination of different things I have seen and the way I would put it together.

Very nice work! Pressing those bearings in must have felt very gratifying. The moment they align and begin to sink is one of the best feelings in the world! Did you go "old school" and use a turntable for the nice radius work on the right hand plate?

I know it wasn't supposed to be the focus of those photographs (your jackshaft set-up is dang nice too), but I really like the shiny edges on your cooling fins. Gonna have to sand mine like that...

Actually I really went "old school" on this project. I used the clutch cover as a template, and just laid out the plate and sawed it out. I also used a fly cutter in the mill to bore the holes to 1.3745. It's kind of fun doing it that way. You can tell by most of my projects I love working with Aluminum.

John,
You never cease to astound me with your talents. That is beautiful work and I admire the quality that is obviously in the design. Thanks for sharing with the members. You're an inspiration.
Tom
