We just started it yet. The shop were he works at does other things and he started doing this as a hobby. So the machines are assigned projects and can only make them on his free time. The shop owner is getting a new machine so he offend it for sale. So my friend is trying to buy it and will make nothing but 80% on this's home if he reaches his goal.
He has produced a few for friends. I have one my self that I have built. One of the best I have seen so far!
