Finishing the centerboard case and half floors

Progress on Tammie Norrie took an unexpected delay due to Hurricane Harvey.  I live in an area that was especially hard-hit by the storm, and though I count myself as fortunate in that my house didn’t flood, however my son and his family lost their house and both their vehicles from the storm.  They are living with us now.  My wife’s car also flooded from the storm, so she’s got a brand new car sitting in the driveway now (and I’ve got a brand new car note), but all things considered, we came out pretty well and I’m grateful for it.

I’m slowly getting back to work on Tammie Norrie.  The centerboard case has a vertical brace on either side.  With those epoxied in place, we can glue on the upper rails which were dry fit on the last post.  The forward and aft ends of the case also have end caps which are also epoxied in place.  Once again, you can never have too many clamps.

With the structural work done on the centerboard case, it’s time to turn our attention to the half floors.  Four floors were installed earlier, but there are also two sets of floors that are bisected by the centerboard case.  The procedure for making the half-floors is the same as was used to make the full floors.

The shape of the floors was traced from the plans onto mylar, and then transferred to 1/4″ ply pattern stock.

Two blanks for each half-floor were cut oversize and glued together, then shaped to fit the pattern.  The block plane and the Sur-form rasp were the tools of choice; the half-floors were a little too small to use the router.  When complete, I had two pairs of half-floors.

The half-floors get two coats of Clear-Coat epoxy before being installed.  The centerboard case is temporarily installed and used to set the location of the floors.

In the photo above, you can see pieces of blue tape to mark the location of the floors.

With the floors marked, some coarse sandpaper is used to rough up the surface so the epoxy will have better adhesion.  You can also see a scrap of wax paper against the side of the case so that the half-floor doesn’t accidently get glued to the case.

After the half-floors are epoxied to the hull, the centerboard case is removed and finished.  The plywood sides have already had two coats of Clear Coat epoxy, so they only need two coats of varnish before the sides are finished.  The “real wood”  receives six coats of varnish.  The bottom of the case also gets a groove around the entire perimeter; this will serve to hold the sealant between the centerboard case and the keelson.

Fun times are ahead.  Next step is to start work on the thwarts.
