Step 4: Lumber / Wood

Picture of Lumber / Wood

From all the research I did the best wood to use is Paulownia wood for a chambered wooden surfboard. However it's not indigenous to my area so I am using the most readily available lumber to me: SPF, Spruce, Pine and Fir. SPF is sold at all home building suppliers and is used for construction. It's relatively inexpensive, easy to obtain and very strong for it's weight and dent resistant, the disadvantages is the wood is denser than Paulownia so it's heavy even when dried.

I purchased 2x6 SPF construction lumber and let it season (i.e. dry out) for a several weeks. When sorting through the wood at the building supply I picked from bundles that were stacked tightly, this makes finding straight and true pieces easier. Usually construction lumber is in varying degrees of dryness and the issue is as moisture leaves the wood, depending on how the wood is cut and the number of knots, the wood will warp, twist, cup or crown in varying degrees. To help mitigate this I clamped all the pieces in one large block so as it dried it would all "warp" in the same rate.

After the drying period, I noticed that the wood was still very straight, so either I got lucky or my method paid off, regardless this saves a lot of aggravation later. Ideally running each piece of lumber thought a thickness planer would remove any cupping or minor warping (next time).

Also I included three stringers that were made from red cedar fence boards. I noticed that cedar is not as dense as the SPF, making a board completely from cedar would be nice too but expensive.
