Tom, I understand your position, but all I can do is honestly show how I go about building this rifle. I try to make it clear that I'm not a professional, or even an advanced hobbyist. I'm just a normal guy trying his first build in 20 years.
Back when I was actively building flintlocks in the 1970s and 80s, there weren't the resources available today. So I undoubtedly picked up some bad habits. But, having said that, I don't feel bad about using the Dremel for tenons. It works well for me, and it is hard to mess up that small, straight cut.
As a cautionary note, in the next update I'll confess to two sins that will probably result in you losing what little respect for me that you may still have. But, as I said, I feel that it is only fair to show what I've actually done, rather that what should be done.
