Making your own timber and furniture oil

Been treating the barn framework with a mixture of 60% linseed oil, 40% turpentine and a drying agent 2%. The old timber beams and uprights needed wirebrushing and cleaning, but now they are all painted with the oil, the colours in the wood stand out. Some of the timbers are pre1750, most from early 1800s, all very local I think. Many had already been used a couple of times at least. 5 new timbers were from local oak trees cut up by Phillipe Abadie at the saw mill less than a kilometre away, and delivered as green oak in Sept 2008, when we started the barn renovation, so lees than 2 years old. The oldest timbers are nearly black and deeply grained, the 1800s uprights are deep red/brown and the new oak as you would expect still very pale but darkening even after 2 years. Great pleasure to see these warm colours come alive from the dust and years of use.
I  have used this mixture on floors (chestnut), the stairs (turkey oak) and garden furniture.
The beans and tomatoes planted in late May are going crazy now, enough for some everyday.
