" One method was to soak the stock with a mixture of raw linseed oil and turpentine (2-oil 1-turpentine)many put this coat on warm or hot."

By soak I would think that meant to immerse the stock in the oil/terp mixture which was possibly heated. Is that your understanding?

Or was it just rubbed on until wood would not take more - i.e. was saturated by the mixture?
