Hi Kevin, and welcome aboard! Wow, that's an innocent enough question, but it got me thinking and I have no idea how much I've spent on tools... I bet if you ask ten guys, you'll get ten different answers to that question. Some guys like to make all, or most of their tools, others buy. I don't know about cost wise, but thinking about the tools I use the most, 1/4" and 3/16" chisel, cabinet makers rasp, scrapers, files... I think what you'll find is that you're going to have a better idea once you start. Each step has it's own tools that you'll need (want). I'm thinking that just starting out, you're looking at a couple, three hundred bucks? I know with me, I didn't go out and drop all kinds of cash up front on a list of tools generated by others. That's not to say I didn't use those lists as a guide. I did and their very helpful. It's just the ten guys / ten different ways thing... I know I'm rambling, and hope this makes a little sense. Other guys will jump in and help, I'm sure. I can tell you I've spent way more than three hundred bucks on tools, I'm just not sure how much I spent when I first started!
