...Or just give them to me for hand delivery dude. We don't live that far away.
Hehehehe. I don't know if you're fully aware of how ridiculous our current project is.

Looking good.

Brando, Technically the hubs aren't knurled. The grooving that is visible in the picture was done by running a tool at a relatively high rate across each plug. Technically, it's not the right way to create a strong press because the cuts are in the same direction as the wheels would see force but I'm very happy with the results so we'll probably just stick with this method since it's easy for our Lathe guy to knock out - and it's pretty easy to replicate in house with minimal skill/effort.

Adam, you're right on the money with this. I doubt we'll do a run of double sprockets again unless they're absolutely needed or it makes sense to do so.

This entire project is heavily influenced by a few factors:

-We wanted to try some new construction methods.
-We wanted to build a lighter more competitive drive than what we used in 2008.
-We wanted to move to an 'assembly' style build method.
-The shop foreman at our machine shop told me to design something 'interesting' for his guys to make - one thing lead to another and yeah....

Here are some more pictures for those of you that are interested:
