My method is straight raw linseed oil. Boiled linseed oil has chemical driers added and will probably need the turps because it doesn't penetrate as well and dries much quicker. I stopped using it when i learned what the original finish was 20+ years ago. The original finish was raw linseed oil warmed in a tank with the wood submerged for variable times depending on condition and dryness. I modify this a bit by sitting the wood out in the sun and warming it up, then applying the RLO with a sponge brush, let soak for a half hour turning as necessary for full on sunlight, gently rub out by hand using 0000 steel wool and wipe off the access with a blue paper towel. Make sure you take a toothbrush and clean out the bearings while wet so there's no build up because it can change the bedding if you don't. Keep adding coats until you like the finish or the wood stops absorbing it. I usually do about 4-6 coats. I've never mixed RLO with turps and the finishes I get are identical to original. Unlike BLOicon, RLO will remain a little tacky when you're done but that's the way it should be and it will go away with handling and use pretty quick. It also naturally oxidizes over time giving a nice reddish tint. Many use stain to try and duplicate this with BLOicon and other finishes.
