Framed Angles

We mentioned on our last post that plank two didn't fit at the bow and the stern.  The reason this did not fit is not yet clear to us, we have talked to Alec in Scotland and Gardner from Hewes and Co. in Maine. We all agree that this plank is an anomaly. This is our second St. Ayles, built on the same molds as our first. Our garboard plank laid on with little effort. We double checked the set-up, the scarph alignment on plank two, both seemed to be correct.  We glued up plank three, and fit on our strong-back with no issues.  Instead of forcing it down into place at the bow and stern, we decided to fix the problem by cutting the plank where it was lifting off the molds at Station one and two and Station ten. 
This proved to be a great problem-solving lesson for the students, and is all part of the joys of woodworking and boat building.  
To check how far it was off, we laid the port side bow section on starboard plank two.  You can see that if the plank fits in the notches at the bow, it starts lifting off the notches as it goes aft.

We stacked the plank pieces on top of each other and cut the scarph with a power planer. 

The cut is in between Station two and three, where the wooden handscrew clamp is.  The plank faired out and fits our strong-back.
We applied epoxy to handmade scarphes cut into the second plank. 
We applied epoxy to the "land" on plank one and the frame.  First, we spread unthickened epoxy to wet the grain of the wood, then we added thickener to fill any gaps.
We applied epoxy to the 2nd plank in order to attach it to the boat.  Success!
