TA RAIDER,
Let me help you out here. I HAVE a degree in gunsmithing I got from the Colorado School of Trades almost ten years ago.
Lots of good info in the posts above, but you BETTER take into account certain expenses that if you ARE going to be a gunsmith will have to be addressed sooner or later.
For example, hours billed and hours worked are NEVER the same. I've got friends that bill WAY more than the fifty hours a week they actually work. Generally they bill specific times for specific jobs. Times the shop rate. So they can effectively bill out over twice the amount of time they are physically in the shop working. Just like an automotive mechanic. And just like any mechanic, hopefully you will get better AND faster at each job. I know I did, though the amount of time I had in any given firearm rarely mattered much to me, because I ALWAYS bill BY THE JOB. A trigger job is so much, mount a recoil pad something different, mounting a scope or DCOA (disassembly/clean/oil/assemble).
Second, NO ONE HERE mentions the cost of liability insurance. Trust me, as a gunsmith, you BETTER have liability insurance. A million dollar policy is bare minimum and it's not free (or even cheap). These days, a good personal injury attorney can run that up well above the $10 M level really quickly. And the LAST person you want to meet is your client's WIDOW'S ATTORNEY.
How to get experience? There are several companies that produce gun specific videos. Like for the 1911 or for Smith & Wesson J frame revolvers, etc. Books on disassembly/assembly from several different sources (there is a series put out by the people who publish Gun Disgest). Plus several books on specific TYPES of firearms, like those published by Jerry Kuhnhausen (his books on the 1911 are THE WORD when it comes to this specific firearm).
THE gunsmith provider of all things a gunsmith will need, including books, videos, tools, parts, etc is BROWNELLS.

Also, if you really want to become a gunsmith you need to learn to think critically. Be able to look at a problem and learn to see the things others do not. Learn to take a problem and turn it 180 degrees on it's head and see if that gives you a different perspective to the problem. Yes, that means you need to learn the right way to fix something as well. But before you can fix it, you must figure out what's wrong with it. Which leads us into know the 'cycle of operations' of all firearms.
KNOWLEDGE IS POWER.
So start purchasing the books. Start purchasing the videos. Then if you want to practice, have your folks find you a BROKEN firearm. Like a 1911. Or a 1903 Springfield bolt action rifle (or a 98 Mauser). Or perhaps a beat up old M1 Carbine. Or a S&W revolver. All of these firearms have problems or issues that have been dealt with over the years by others who came before you. A broken firearm is always cheaper than a working one, so go find one on the cheap. Then figure out what's wrong with it, order the parts and away you go.
Last but not least, continue to use the internet as your source for asking questions, just like you did when you started this thread. And continue going to school, especially keep your computer skills up to snuff.
If you have any specific questions, let me know and I'll do my best to answer them.
I may be incorrect, but Susanville Comm Coll no longer offers an associates degree in gunsmithing. OR anything else related to becoming a gunsmith anymore.
