Lloyd,
Old topic around here. There isn't a gun around that didn't have machines involved in it's manufacturing process.
When someone says 'it's a hand-made gun' they either have no idea or are just using a vernacular for a gun that is hand fitted and finished on a lot of the surfaces.
For example:
How do you make a barrel without a lathe?
How do you drill a hole without a drillpress or mill (and yes, I've seen and used handpowered drill presses. They are still machines regardless of how they are powered)?
How do you make a screw (pin, to some of you) without a lathe?
Machines came before guns. Machines allowed for the making of guns. Without machines, guns would not exist. The "all hand-made gun" is a myth. At least any gun that we'd want to use for sporting purpose.
