Though much of what you say is true, I’m thinking you might scare the guy off, haha!
I studied archtop building some years ago. Nothing on a professional level, just my own research, and seeking out builders to ask advice of.
Bob Benedetto was very gracious to share his time over the phone. I highly recommend his book,
What I found in my research is that many people who built archtops had no experience in woodworking at all. A lot of those folks purchased all the tools they needed because they had none prior to building. They were that green at it! They did it all with inexpensive, consumer grade tools.
I met one older woman near me who got into building. She showed me eight guitars she made, including a Dobro. She was quite an inspiration to say the least.
My entire reason for posting is for Sergio’s benefit. Having the x-carve will decrease the amount of time spent in getting the perfect shape. In addition to that, you actually can get the perfect shape! I can’t imagine the process of creating an archtop with a drill press, as defined in Bob Benedetto’s book. That’s the exact reason I never even tried. Yes,I’m kind of lazy! However, with having an x-carve to take care of some of this work, building an archtop is number one in my bucket list. There will indeed still be a lot of hand work, but the x-carve has cut the drill press method in half, if not more. Forget about the inlays!
In short Sergio, go for it. The worst that can happen is that you scrap some wood, big deal. To cut down the expense risk, make your first out of pine. Others have and they turned out nice. You won’t get the same sound as you would with a good tone wood, but the practice will make that one look better, and spending the cash on good tone wood will put your mind at ease having built the “junker” first.
Good luck my friend. I sure would like to see what you end up with.
