I don't know where he got his money, but it wasn't making guns. He seems to be spending tons but the incoming appears a trickle in comparison.

From my visit, I'd say his burden shop rate would be up around $100/hr. That's no amortization of engineering/development. That comes out to 30 hrs to make a $3k gun (his cost). If I'm wrong by $50/hr high ($50-75/hr is common for a small low overhead machineshop), that's 60 hrs to make a $3K gun (his cost).
