Top Sides Fiberglassing and Misc Woodwork

After finishing glassing the footwell I moved on to the cabin top and the remainder of the front.  This all was much easier work than the footwell (see last post).  It went quickly without any issues.


I chose to use one piece of fiberglass to wrap around the front of the boat to the opposite side.


I made some additions to the fiberglass schedule on the front of the cabin top.  Before continuing the fiberglass down over the front of the cabin top I added an additional layer of biaxial tape along the front edge.  This is in response to reports of separation at this join, especially with PocketShips that have a removable tabernacle as I am planning on employing.


I continued the front fiberglass over the inside edge of the bow.


Here is my table saw jig setup for cutting the 10:1 scarfs for the rub rail.  This jib worked immensely well at cutting perfect scarfs.  Took literally 10 minutes to build.


If you look at the stack of wood just to the left of the white PVC you sees all the consistent scarfs cut with the jig.  I chose to make the rub rails out of black walnut because I love the way it looks when varnished.  It has a deep brown/black color with lighter grain patterns.


The PVC pipe is my steaming box.  After a failed attempt as getting the walnut to bend around the bow I decided that I would steam bend it.  The PVC pipe is 7' long and has a brass nipple at one end to attach the steam generator.  I've already tested it and it should do the trick.


I also used the block walnut for the toe rails.  The bend needed here isn't as severe as at the bow.  I was able to achieve this bend with no problem.

Finished Cockpit Glassing

So 25 yds. of new fiberglass arrived on Tues.  Since everything was prepared I rolled out a length for the center of the cockpit including the foot well.  This was by far the most challenging fiberglassing I've done to date.


The geometry of the footwell in combination with the front of the cockpit and the transom makes for some interesting curves and bends.  I cut darts and overlaps where I thought it made sense and smoothed everything out.  Again, trying to get everything as close and as smooth as possible before mixing a drop of epoxy.


I started laying down the resin with the center of the footwell and worked my way out and up the sides.  I had to do this while sitting in the cockpit and trying to avoid disturbing the dry glass that was there.  This involved some pretty strange contortions where at times I was on one knee with a leg hanging out of the boat while leaning over the footwell.  I had a difficult time with getting out all the bubbles in the corners and to a lesser extend the bottom edges of the footwell.


From there I moved on to the forward center section of the cockpit right behind the companion way opening.  This being flat was much easer to do.

The rest of the area to be epoxied could be reached from outside the boat and also flat so it was much easier to do.

Upon inspecting the work I noticed that I still had some moderately sized bubbles and lifting in the corners and along the edges of the bottom of the footwell.  I went back and worked out as many of these as I could.


After about 2 hours (using slow hardener) I went back to check the work and some of the bubbles had returned (or I just missed them in the first place).  I put on a latex glove dipped my finger in alcohol and pushed these back down.  That did the trick for most of them.


After drying I noticed a few small bubbles that I will have to take care of and there will be some sanding in the corners to remove a few rough strands of glass.  But it is a step done.  From here out the glassing should be MUCH easier.

Glassing the Cockpit

After getting the cabin top glued down I went to work rounding everything off.  I did most of this work with a sanding block and 60 grit sandpaper.  It was pretty easy work.  I also did some filling of cracks, divots and holes that I incurred during the process of building.


I rolled out the last of the fiberglass that came in the kit.  I knew I was going to run out of this because I chose to fiberglass a lot of areas that aren't called for in the manual.  These included the bottoms of the seats and the bottoms of the foredeck and cabin top.  I ordered more from CLC.


I laid out the glass and cut darts to fit the corners.  Using a large "wallpaper brush"  I brushed and stretched the fabric.  Instead of using my normal roller and squeegee method I saturated the cloth using a cut-down chip brush to keep the fabric stretched out as much as possible while I was wetting it out.


For this round of fiberglassing I chose to use a technique that was outlined in a video I found at OffcenterHarbor.  This is a for-pay web site that has a lot of information about small wooden boats.  The video was one that shows how to fiberglass a stitch and glue kayak.  But the techniques that were demonstrated seemed like a method would also work for me.


In the end the technique worked nicely and I felt very much more in control of the wet-out process.  As I got better with it the technique the results improved the starboard side was done first.  The port side used noticeably less resin and I had less pooling as I learned the technique.  The final results on both sides were very good.  I actually look forward to do the cabin top and the bottom of the boat with the same technique.


The footwell and set centers will be done next.  I'm waiting for more fiberglass to arrive so that I can continue.
