I was just looking into a set of chisels for mortising barrels and locks and for use in carving stocks
I am just curious as to what you guys use and brand
Any advise is appreciated
Take a look at these from Track of the Wolf. I own some and they're good chisels. They also have other gun smith/building tools. It's a good starting point.
Chisels for Inletting, forged in the U.S.A. - Track of the Wolf Also, I'd recommend a good Dremel kit, good hacksaw, good wood and metal working files, three sided files, There will also be certain tools you'll have to make yourself such as channel planes (not really necessary but they really work well and should cover, 13/16, 7/8, 15/16, 1, 1-1/8 inch which are designed (by you) to clean up a barrel channel... There's quite a bit more, but it also depends on how deep you plan on getting into the building. I honestly don't know if I could complete a list... Tap and dies, you'll need them. Ram rod drill(s), depth gauge, drill bits...
When I started building muzzle loaders I just jumped in with the tools I had, and tooled up as I went from there.
