I am almost sure that it will save you a lot of money when making those wheels... it might weigh a bit more but it will still be cheaper...

If you have a hex broach and an arbor press, it will be much cheaper than $15/wheel to get the hexagonal hole.

A 1/2" hex broach is only like $200 on McMaster, so if you plan on making more than 13 hex broached parts, its probably worth it. (A 6wd live axle would require 16: 6 wheels, 10 sprockets.)
