Rich,
I've been on the road so much that I haven't had time to respond until now.
All these guys have your best interests at heart. We all took our own path to learn what we did and I would bet that most of us are still learning. A few years back I was at the Gunmaker's Fair and a bunch of us were sitting around Acer's tent critiquing my mostly finished squirrel rifle when Taylor said, " I really like your carving around the tang. The problem is it is sitting on top of an 1/8th inch of wood that shouldn't be there."
I had labored numerous hours on that bit of carving! I was mortified! But when I got home and took a hard look at my "masterpiece" I had to admit he was right. I took my Nicholson 49 and, tearfully removed both the carving and the 1/8th inch of wood. I then re-did the carving (it went faster the second time around) and got the gun finished by the next Fair. I got a yellow ribbon for - you guessed it_ carving. Thanks Taylor.
On your riflegun, you have to think of a rifle as a functional scupture that has embellishments applied after the fundamental form has been designed, executed and, at last, arrived at the point where it is ready for the finishing touches. That means, for example, that the wrist is carved as an arcing cylinder that flows into the lock panels. The lock panels are actually perched on top of the portion of the cylinder that flows into the forestock. Peter Alexander's book deals with this the best, I think.
There is a lot to learn before you build a good rifle. My first has been mistaken for a fence-post! I sawed the blank out of a tree! The curve of the trunk looked about right. But it wasn't in reality. It took me 10 years of attending the Gunmaker's Fair and 6 entries before I got it right (and "Journey" isn't perfect - there are 20 points of deductions on that tally sheet!)
So, if I were you I would start saving up for a kit. Look at Barbie Chamber's kits. While you are saving up keep practicing on the stock blank you have. Eek as much useful experience out of it you can! Also, get your hands on one of the books like Recreating the American Longrifle or the Gunsmith of Grenville County. They are great references I still refer to them from time to time.
Remember, most of us do this for FUN! And as you have a question, remember, too, that you ar3e amongst friends.
Best Regards,
JMC
