Fairing the Chines:  During this session I finally got down to fairing the chines.

Several weeks previous to this session I had taken the hard edges off of the chines with a hand plane.  Today I changed the sandpaper on my flexible board from 36 grit to 40 grit and smoothed out the bumps and other irregularities.  The job went well and only took about a half hour per side.

A tool that comes in handy, if you're extra compulsive, is a can of fast drying lacquer.  You can use the lacquer to create a "guide coat".  After sanding the guide coat area, the lacquer will be sanded off the high areas and will remain on the low areas (see the area above and to the right of the can).  At that point all you have to do is keep sanding until all the lacquer disappears or add filler to the low area and sand again.  This will ensure a fair surface.

Shown above is a cross section of  part of the area cut from the transom.  Note the gap in the fillet.  While fairing the chines I wondered if there might also be a gap below the area being sanded.  I took a Dremmel tool, and using a burr attachment I cut a small inspection hole.

As soon as the burr penetrated the chine it dropped into a gap.  I knew then that I would have to run a slot down the entire chine to get rid of a channel that might conduct water/moisture.

 

Shown on the right is the Dremmel burr tool, and on the left is the Dremmel grinder that I used to cut the slot.  When I went to get additional grinder blades I found out that I had been using a metal blade instead of wood/laminate blade.

This is the proper blade for the job.

While cutting the slot I needed a light to check for gaps as I went along.  After doing some searching I found the proper tool right on my key chain!  It's an LED light that Radio Shack sells for about four bucks.

This is how I used the LED light to look through the slot to see the gaps.

This if the faired chine with the slot cut the length of the hull.

During the next session I will repeat this procedure on the starboard side.  After that I will fill in the slots with epoxy. 

Total time spent in the shop today was about 2 hours.
