Before we plank....




 So the frames are standing, the engine and fuel tanks are in, the Transom and stem are up, there are still a few things that need to happen before we start planking (and remember, there will be two layers of plywood that goes over the planking later on).

First, before the cross bracing can come off the standing frames, we need a little more infrastructure to the framework of the ship.  Where the sharp angle or Chine of the hull turns up, there needs to be some solid wood built into that angle that gets notched into the frames.  In the photo to the left you can see the Chine which we have laminated out of SYP and Doug Fir (3 layers of 1X stock).  The laminated chine was easier to fit to the curves and mitigated issues around butt joints (because planks don't come in 44 foot lengths ;-0 ).  Later, the planking will be fastened to the frames, chine and stringers (on the bottom part of the hull).

Next we needed to make and install Deck Beams to the frames.  The Deck Beams become the frame work for the deck which is also the cabin ceiling depending....
The Deck Beams were cut from whole pieces of 3 X 8 Douglas fir with a 3.5 inch crown.  Many builders laminate the deck beams on a form but I chose to cut mine out of whole timbers.  They were sanded and then oiled with Tung oil.  You can see the curve (or crown) which sheds water that hits the deck and the difference in finish between a coated and uncoated beam from photo above. 

After a final fairing of the frames, the last step before planking is to put in the Stringers on the bottom (next blog topic).
