Hawkeye,
I think Bill in MD had some good advice. On this forum it is an under-represented voice:
"When recreating 18th and 19th century long rifles, a good rule of thumb is to use the tools that gunmakers back in 18th and 19th century used to create the originals. Never allow the destination to rob you of experiencing the journey."
The best money I ever spent on gun tools was not on routers, dremel tools, etc. (which I did spend money on). It was on good quality chisels and gouges. (In my case I went with antique English tools. But modern made Pfeil "Swiss Made" tools or Two Cherries tools are every bit as good and they come polished and ready to sharpen. Antiques usually have to be reconditioned, which is a learning curve in itself.)
One of the best investments I ever made in terms of time is closely related. It was learning to properly sharpen and use my chisels and gouges and planes and scrapers.
