I think that I'll finish off reading The Gunsmith of Grenville County, then make my choice if I want to get a Chambers kit or build from a plank.
Apparently, inletting the barrel and ramrod channel is the most difficult part, and almost everything else is just fun.
I was less interested in a kit where I just assemble the pieces, but if the Chambers kit involves some inletting of pieces, then that may be something I would be more interested in.
I'll have to look into those rifle styles. I appreciate all the help, everybody!
Oh you really stepped in it now ...
When you are finished the gunsmith book, pick up "Recreating the American Longrifle" - pretty much the same with a few differing points - It's cheap and a fun read and good to get a couple different perspectives.
Barrels, Rice is pretty much considered top of the pile for production barrels, I like Colerain and Green Mountain as well, but if you are looking at a swamped barrel I believe Rice & Colerain are the only options. (Chambers kits use Rice barrels BTW)
So - if you are looking at a Lancaster (Pennsylvanian-style) rifle, your barrel will probably be swamped and anywhere from 32" - 44" .54 is a good choice, You would not want to carry a .50 44" barrel for very long. .58 would be even better.
If you were to go with a half stock, Hawken style, go with a tapered barrel, .54 at least .58 would be better. (lighter that is)
Locks and hardware, most hardware is pretty much the same supplier to supplier, but they all have different people doing the castings, so quality can vary - Chambers has very nice castings.
Chambers locks. nothing else. (I actually have about 10 of these on hand)
Your plank, Sugar Maple, (good luck!) or a particularly hard piece of Red Maple - other Maple species are too soft. It will be challenging to find a board over 2" thick. Ideally 2 1/2" is what you are looking for.
If you are going for Walnut, shop carefully, again hard to find a board thick enough and newly cut Walnut just does not seem to have the density of a 200 year old piece .... (oh well)
Other options are Cherry, Birch and Ash - Curly Black Ash can look pretty remarkable.
As far as building, yea, barrel channel and ram rod channels are the no-guts-AND-no-glory jobs, but you can get 90% of them done with a router in a little over an hour. (unless you don't know what a climb cut is .... then you are in for it!)
The challenging moment is drilling the ram rod hole. (you need a 4' drill!)
So yea - the payoff really is looking at your hands thinking "I made that with these" ... let us know if you need any pointers and HAVE FUN!
