I know one who cuts his own trees, and forges his own barrels and other furniture as requested. But even he usually buys the lock components other than the lockplate. He made one completely by hand and fashioned 100% of the components (including screws & bolts) just to say he'd done it - and you could buy a 2012 Jeep Wrangler for the same price.
Didn't ask if he used grass for toilet paper on his breaks while working on it. ;-)
