Milling Stringers

We spent a couple days ripping and planing stringers out of CVG Doug Fir and Sitka Spruce.



The stringers were ripped a few millimeters oversize.  I used a new Freud Thin Kerf Glue Line blade that did a really nice job.




The main hull needs 60 meters of 19 x 25 stock for three courses per side,  The ama requires 38 x 25 stringers and a 25 x 25 deck beam.  The ama is expected to take some pounding, so the timber is a bit beefier.



I was able to rent the use of the large Powermatic planer at the Northwest Maritime Center.  The planer allowed me to remove any saw blade lines as well at get the thicknesses down the the millimeter.  All of the stringers were run through together to ensure identical thickness.  Nice scarfs are dependent on consistent thicknesses. The stringers also have to fit CNCed notches in bulkheads and come out flush with the hull sides.

Task time: 15 hours
Total project time: 253 hours
