Cabin Top Work

DSC00022The cabin top has been glassed with 2 coats of epoxy.  I noticed the cabin top edges looked a little thin (weave not quite filled), so I went over these areas with a 3 coat of epoxy.

DSC00023I wrapped the glass up the side walls of the mast box, which already had one wrap of fiberglass all the way around them.  (Others have suggested doubling up this area of the mast box with additional okoume plywood.  After thinking this over, I decided against this because it would prevent me from screwing hardware into the cabin supports just under the top.  So I decided to wrap this area again for additional support.  Not sure it needed it…but it made me feel better).  DSC00026I used a round over bit on the top and bottom of the fore and aft cabin top edges.  DSC00027This finishes off the cabin top edge very nicely.  I have used a 1/8″ rounder over bit a lot on this build.

DSC00024The bow of the boat will be finished a little differently.  I cut it flush with a flush cut router bit and Japanese draw saw.  I am going to fit a solid piece of Sapelle here like I use for the rub rail.  I’ll tie this piece into the rub rails for a finished look.

Details to follow.

 

 

Installing BH 1-3 and Mast Box

With the mast box built and glued to BH3, I was ready to move forward with the installation of BH 1-3.    DSC00016Stem installed with cleating.DSC00001I used a sharpie to mark each of the cleats.  They all need two coats of epoxy and routered edges.  DSC00005Mast box and BH 3 installed and filleted.DSC00002BH 2 installed plus cleating on both sides of the stem installed.  DSC00004You can see the fiberglass I wrapped around the lower mast box in this photo.  DSC00012More stem cleating installed.DSC00011Glass wrapped around the top of the mast box.  DSC00006Ready for BH 1.DSC00006I used the supplied plywood panels to properly align all bulkheads.

DSC00004Notice the deck support piece clamped in this photo.  Where does it describe the installation of this piece in the manual?  To my knowledge, it doesn’t.  I had the support beams filleted and then just happened to stumbled onto this piece.  Fortunately, the fillet had not cured.  I removed the sides and bottom fillet just in time to glue up and install this piece.  DSC00003The top of the deck supports joining BH 2.  I kept this area clean for installation of the deck top to come later.  Sure glad I found this BH 2 support piece in time to install before the fillet set up.

DSC00001Cabin supports installed (though they didn’t exactly line up with the cut outs in BH 4) and drilled for under cabin accessories.  Note, the plywood supports will come off in a later stage.

Just one step of a time, keeps things moving forward.

Glassing Mast Trunk

The plans call for wrapping the outside edges in fiberglass.  I decided to add the glass while the epoxy was still curing to avoid sanding.  I’ll add additional epoxy to the weave in 8-10 hours.  DSC00002These top edges will be cut flush with the top of the mast trunk, with a razor blade in about 8 hours.DSC00003This bottom wrap was a bit of an after thought.  It would have worked out a lot better if I had rounded the bottom edges before attempting the wrap.  I’ll try to work a little more epoxy into these white edges after things set up a bit.

Building Mast Trunk

After several last minute vacations, before my kids go back to school, I found some time to continue building Shackleton.

I decided to follow Dave’s lead (building #243) and build the Mast Trunk on the bench.  After mocking up the process dozens of times, I finally decided to just start building.  The process went rather smoothly as follows:

  1. First I rolled and brushed all joint, dado and fillet areas with unthickened epoxy.
  2. I then brushed thickened epoxy into all dados on BH3, mast ramp and bottom plate.
  3. I then positioned the mast trunk sides into the dados on BH3.
  4. I then shot two 3/4″ staples through the bottom plate, into the mast trunk sides (at the forward bottom corner location). This held the lower mast trunk sides vertical.
  5. I then positioned the top ramp piece and clamped it to the mast trunk sides.  This held the upper mast trunk sides vertical.
  6. I then filleted both inside and outside joint areas of the open mast trunk (this was really nice because it allowed great access to create the inside fillets).
  7. I then placed the Y piece on the top.
  8. After checking all alignment, I weighted the top and clamps the sides together.

I’m having fun, baby!
