Stock finish/refinishing Link added

There's lots of ways and lots of stuff to use, right now I'm going to hit one. I got the original information on this from a string at The High Road, but they've been unavailable for the last week or so and I can't find the thread to link to.
(update: this is the link)

The stuff I used here is Minwax Antique Oil Finish. Really nice finish, and there's no stain involved so it won't change the color of the wood. And being an actual oil finish, it soaks into the surface of the wood, fills pores and/or grain and once it cures it's a very hard, protective finish. Easy to repair if damaged, too.

Start with a stock that's been sanded, grain raised, etc. Use a soft cloth and put a generous coat on the wood. 'Generous' does not mean 'dripping off', just covering the wood nicely. Put it aside for a day to dry.

After dry, get the steel wool out: the first few coats are to seal the wood and fill in the grain, so you want to clean the surface off for the next coat. So use the wool to cut the finish off, down to the wood. That'll leave what's in the grain. Then put on another coat, set aside for a day, repeat as necessary. Depending on the wood, it can take anywhere from 2-5 coats to fill the grain most/all the way.

Now you're at the point the grain is completely or almost completely filled, so for the next stage you put on a light coat, let it sit a few minutes until it gets sticky and then buff it with a soft cloth, then set aside a day, then steel wool it off. This stage is to finish filling the grain and level the finish, so repeat as needed.

At this point you've got two options: you can go for a matte finish or the full-out gloss. If the matte, two ways to do it. One is to put on the final light coat, let it dry, and then wool it down to the wood; the stuff is soaked into the surface and will give good protection, and this gives a dull finish. The other is to put on a final very light coat, and buff it all off, as much as possible: this gives a bit more shine than the first, but not as much as the gloss finish. In either of these cases, after putting the final coat on let it sit for at least two days so it can cure hard.

For gloss, wool it down to the wood and then put on a very light coat and, after it gets sticky, buff lightly with a soft cloth. You don't want to remove much, just leave the last coat very thin and smooth. Again, let it cure for at least two days, and then buff it with a pad made of burlap.

Done right, this stuff makes a beautiful finish, very hard and protective. And if it gets scratched or otherwise damaged, you can sand or wool it clean(whichever is needed) and repair it by putting on a couple of coats.

The M1 Carbine I built turned out very nice, and the stock Og found is a very nice piece of walnut which I decided needed a proper finish. So I smoothed it a bit, then treated it with this finish. Here's the result













This is the semi-gloss finish. Took about two weeks with the drying periods, and came out flat beautiful.
