I just finished my bed in my '48 using wood that my wifes uncles had sawed up close to 70 years ago. It was rough-sawn lumber and stored in the barn loft along with piles of other woods. The wood I chose to use was Cherry Sap Wood which the beetles absolutely adore munching on. After I had the wood all milled down I sprayed it down on both sides with "Bora-Cure" which is basically a solution of boron and glycol. Of course the wood was bare of any finish and the wood soaked it right up. I let the first coat dry and gave it one more application to make sure the wood got a good penetration. The glycol additive really assist the boron to penetrate deep into the wood and after spraying both sides and ends with the product I'm hoping it will work. After it dried I sanded the wood down with 220 grit sandpaper and began applying my Tung-oil finish. The worm holes produced a patina in the finished work that I really liked and being it was from the family farm even made it more special.
