I have a friend who claims to be a traiditionalist. He would rather use a brace and bit, or scrape the varnish off with a piece of glass. His thoughts are that the best furniture was built without power tools. He will hand cut a dove tail, or mortise joint.
My argument with him is that "IF" power tools and tools like the Kreg Jig were available 200 years ago, they would have used them. I think they did what they did, because of what was available to work with. Its evolution, progress, or whatever you want to call it.
When a guy like me can make a frame and know that it won't fall apart during assembly, then I feel like I'm doing the same thing my fore fathers did. Since purchasing my Kreg Jig, I have been looking at projects that I would never have attempted before out of fear of failure. I'm just waiting for the weather to warm up (I don't have a shop or garage) so I can try more projects.
Now I can say, I did that with my own two hands.
