I didn't put this in my post late last night. But it really comes down to what you desire to get out of the education. If you just want self knowledge on how to better work on your own firearms. Then most of the at home Gunsmith courses will do that very well. If your looking at going to work for a big name firearms maker, I.E., Remington, Ruger, Winchester, ect. Then the at home study course will not cover all the bases.
As Balming is stating doing sometime as an apprentice to an already practicing Gunsmith is a great way to learn hands on. Also getting a nice library of firearm dismantling books or CDROMs will be a big help and go a long ways.
When it comes to the large equipment almost any hardware store carries them. Also about 75% of the hand tools you will need to get also can be found now days at most hardware stores at cheaper than "Gunsmithing" tool outlets. There are also some tools that you can build yourself. Some tools and tools sets you might only use once every 5 years. These tools can be gotten as you need them. When it comes to gun vices be it just to hold a firearm why you work or clean them, or shooting vices to use for sighting in firearms, these can either be built yourself or bought pre-made. Which will save money for beginners. Also benches, work or shooting benches, can be self built and will save money. For those who are going to try to start their own Gunsmithing business, your own garage might work for starters. This depends on your state and local laws. If your going to also have your own business as a gunsmith you will have to get a Dealers FFL. It all takes time and money to get started.
So either way you look at it, if your going to do home study, apprenticeship or a full collage. It will take money and time to get everything started. Also helps if you can find a town or city were there is not already a huge number of gunsmith in business.
