The old saw about linseed oil/bee's wax/ turpentine/ finish goes like this. A coat a week for a month, a coat a month for a year, a coat a year for the rest of your life. Works for me. I keep some in a can in the shop, and about once a year heat it up in a double boiler made from some cans (NOT IN THE HOUSE, unless you live alone, or have a spider problem) and rub it into the wood, it'll be like a soft paste wax at this point. I usually warm up the stock before I do this as well. Wipe it down with a soft cloth afterward, and its good for another year.
