The first live axle version did use a coupled stock sprocket from McMaster, but I decided to move away from it because 1/2″ bolts (and 3/8) are actually really undersize, so it would have been much harder to make it spin true. Asking people to drill through steel in a coordinated fashion was also one of the things I thought was extra risky.

Plus, more things for you to waterjet!

Why not just buy pre-made sprockets?

first, i agree with you 100% on your rant.
second, firstcut(dot)com is a decent(but expensive) CNC milling operation. they are pretty quick on quotes too.

Very cool. I have been trying to figure out how to build SOMETHING ride-able with a giant hobbyking outrunner attached to it (except not fankart style…) since seeing all of your posts.

I will definitely be following closely, and depending on exactly how ‘not cheap’ it is I may try to build one! Thanks for taking pity on us deprived commoners! :P

I haven’t gotten past the first paragraph yet, but w00t!

I am the one that was clamoring about how ‘we can’t source / make these parts!’ on hack a day, so this is a GREAT post to see!

I’m sure many will appreciate the instructions. Just a tiny leetel suggestion if I may: please consider also hosting the project on some ‘non-instructables’ site (like http://makeprojects.com/), considering that since it boldly went ‘profit-oriented’ there are quite a number of people out there who hate the guts of instructables.com with a white hot rage compared to which even the fiery depths of Mount Doom would seem like a mere Bose-Einstein condensate.
