Not trying to throw cold water on this post but in order to build guns, whether from kits or from scratch, you need tools and you need to know how to use them. Not necessarily a lot of them but you need good quality ones and they are not always cheap. I think most of us that do this, have some sort of background or at least interest in woodworking so have at least some of the essentials. For example, a high quality, 1/4 inch chisel will do most of your work. A few planes, rasps, files, drill bits with an egg beater drill and one or two gouges will suffice at first. Try going to flea markets, see if you can find someone that has antique or used tools for sale. You can save a lot of money there if you are careful. However, that can be tough if you are not familiar with tools as you might pay .25 cents for a high quality one made of the finest steel or $3.00 for one made of pot metal that can't be sharpened to cut butter. Any chance you can find someone with some tools that will help you with your first project so you can see if this is for you? As far as what you need, most of the books have a decent list of the essentials.
