I just finished my first and second rifle builds. Not from planks, "parts sets". I started the Isaac Haines but got lost. I didn't realize that there is a whole lot of "know how" needed to building a muzzleloader. I drove down to Alabama and took one of Mr. Jim Parker's gun building classes. I purchased a Jim Chambers' Pennsylvania Fowler to build in the class. It took me 5 days, 12 hours a day to get it put together. I have a very high respect for all you skilled gun builders. Rifle building is an art form you don't learn with two rifles. My hats off to you!
Below is a picture of my builds. I'm a little nervous showing my rifles with all the beautiful rifles that are shown on the site.
Top: Jim Chamber's Pennsylvania Fowler in 20ga., 46" barrel.
Bottom: .50 cal. Isaac Haines parts kit. I purchased from one of the forum members here. Barrel and hard ware from TOTW and stock from Dunlap woodcrafts. I have not had the courage to attempt any relief carving, wire inlay or patch boxes yet. I did enjoy the builds and plan to do another.
