Adding cranks to a road front or rear hub?

I built a wheel like that out of a 700c deep-v rim,

are you building a bicycle or a unicycle, because you said you are in a welding class but using carbon forks, bicycle forks have a rake, uni frames are straight, you can just locate a used uni to cannibalize for 50 bucks, some cheaper ones are 50-100 dollars anyway. would be way cheaper to just do that than to buy and pay shipping, all you need is a wheel with no offset like on a single speed or front wheel that has the same size flange on the hub as the uni hub, assuming you know how to spoke a wheel.
