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.

You can take the TOOLIE out of the shop but you can't shop out of the TOOLIE.

Nice job, I like the freewheel setup!

I think I see your freewheel bearing on the gear that goes to your pedal sprocket. Did you build that too or is it store bought?

Not to answer for John, I'm not sure if John made his or not.You can order a freewheel adapter that threads into the freewheel with a 5/8 bore.They are a little pricey.

Toker is right, you can buy the freewheel adaptors at either Staton or on e-bay. They have the
1 3/8 thread on the O.D. and a 5/8 bore with 3/16 key I.D.

The reason I don't get into selling parts is there are just to many variables with different bike frames. I have enough parts, like different cranks, sprockets, and enough material around to make everything fit. I had to do some machining to the sprockets, and adaptor to get everything to fit.

I guess the one thing I did forget to mention on the first post was that the jackshaft is going to a 3 speed Sram I Motion rear axle. The final gear ratio is 4.22 to 1. I may have to go up or down a couple teeth on the jackshaft out sprocket.
