Well, since you are just starting out, I say forget the carving part. Learn to build a good solid correctly built rifle First. That will take 5 to ? depending on your skill. Nothing screws up a good rifle more than poor carving, cause you cannot see past the poor carving. And forget about Making it My Own $#@*, if the urge his you. Many many many have put $1000, in rifle parts & end up with a $200 rifle.
Keep it Simple, Basic, Clean, Slow, THINK before you do it. And if you do a Precarve, get ALL the parts from the same guy. (His pattern is inlet for His Parts) Absolutely DO NOT jump into this & start inletting things. There ARE steps you need to do In Sequence & if you do them Out of Sequence, you are headed for trouble & on allot of things, you cannot back up, what is done is done. (I have a step by step if you email me)
Chisels. Like asking What Beer is the Best ? 40-11 dif answers.
For inletting & just starting out, I suggest Inletting chisels like they show on TOW. (Chisel BC-14 ?)They are all steel, easy to use, easy to sharpen & last forever. Dunlaps used to sell them as a set. Log cabin may sell them as well. I suggest a straight & a curved in each in 1/8", 1/4" and 3/8" wide. I know I built at lease 2 dozen rifles with just those & a few hand made scrapers. And I still use them for allot of jobs. See the handle below I slip on of removing allot of wood.(Saves you palm getting sore)
I like them & I also use allot of Flexcut carving tools on Inletting Locks, because I like the handles (palm type) Some builders like long handles, others like short palm type. I have several good sets of long handle German chisels & never touch them. Don't like the big long handles. (Note I built ? 60+ rifles before I bought the Flexcut tools)
You will need a Mainspring Vice & a few other tools as you go. A small table top Drill Press is nice to have. Make or have someone make you a Drill Point for the drill press. This is made from a 3/4 x 8” bolt. A push handle for the chisel made from piece of hickory. I think Dave Rase or Dave C ?? Someone on here makes & sells a Drill point for doing the underlug & RR tube holes. Mine is made from a old hand made C clamp my grandad made. Couple scrapers made from cheap carving chisels from flea market. Heat red hot at bend, quench it in a cup of motor oil. Couple from drill rod from the hobby shop. Heat, bend, quench.
Here are a few of what I use.
Also keep in mind you don't need to spend $200-300-400 on a bunch of expensive tools starting out.
What they look like & cost means Nothing, as long as they get the job done you need from them.
