The Sitka Spruce for my spars has been stored since thickness planing in July 2008. The thickness was still accurate and the moisture content was 9 percent. The layout of the front center section spar flanges, to utilize the best areas of the spruce, was the most time consuming part. Making the cuts was the simple part of the process. Supposedly it takes a 5 foot Sitka Spruce trunk to yield spar grade lumber. If this has been growing hundreds of years the least I can do is take an evening to optimize the postion before I cut. This included making full size templates on drafting tissue. This might seem to be over doing it, but these spars are 1.86" thick and getting Sitka Spruce this thick isn't typical.

Spruce spar stock width is ripped on the bandsaw. The narrower width was easier to hold and cut using my taper jig for the tablesaw cuts. Yes, a big smile! I built the taper jig to make these cuts in 2009 and the wood was purchased in 2008. My work schedule the last few years has allowed precious little building time. |

The 2.5 degree cut was perfect and the simple part.
