There is a big difference between making a gun for a hobby, even when you've done it lots, and making them for a living. When someone is paying you hourly, or you're paying yourself, you must learn quickly to work fast and efficiently. Otherwise, you or your boss will go under.
I worked for a little over three years for a gunsmith, making Hawken rifles, from precarved walnut. I was hired to create the prototype, and it was the pattern for every rifle thereafter. Over those three years we added models like full stocks, short ladies and kids rifles, and a pistol. But working with a precarved walnut stock that was very close to finished dimensions, and uniform parts, allowed me to turn out a rifle in a little more than three days, completely finished with DemBart's Oil, and browned with Birchwood Casey's Plumb brown.
My point is that if you're living depends upon it, you will learn to work fast and efficiently. But when you're doing it for pleasure in your spare time, and it doesn't matter how long it takes, think of it as making love. Savour it.
