Hex Axle- How to

[HammadB]

We are looking to switch to a hex axle system this year, and I honestly have no clue how it works, is hex as simple as slide a hex-broached wheel/sprocket on and then snap ring it?

We are looking at WCD style for next year, and were thinking of using super shifters/tough boxes (repacked with our own plates) with a hex output. We want to have it layed out as such:

gearbox-->Sprocket-->Tubing w/ bearing block-->Wheel. Can we use the long hex axle that AM sells or do we have to machine our own? We are using performance wheels, for the time being...
