Getting close to the finish


 In the past week I first carved the letters of the boat's name on the rubrails near the bow, in English (starboard) and Greek (port).  I used a borrowed gouge and sharpening strop and my own rubber mallet to do so, and it was tricky but ended up being good enough (first photo).  I then nailed and glued the decorative top on the centerboard trunk.  I sanded all tops and insides again and put on a first coat of epoxy on those plus locker doors, oars and masts.  Then I filleted the keelson-to-garboard joints on the inside bottom and cut out a scoop on the transom to fit an oar to use as a scull.  I had to stain the transom reinforcements (which are aspen and very pale) to match the plywood, and used epoxy tinted dark with Minwax stain.   Finally, I drilled the holes for the oarlock sockets with a 7/8 inch spade bit, glued on some reinforcements for the oarlock boards from under the side decks and drove a couple of screws through from below on each one for good measure.

I then sanded the first coat of epoxy and laid on a second one.  The weather has been quite cold, so to encourage curing I kept  the garage door closed and gave the garage the occasional blast from a space heater; the combination made the fumes pretty bad, and I was very glad to be wearing the respirator.  The boat is looking beautiful already!  [second photo]  When the decking is painted and the insides varnished it will look even better.  After that I am going to highlight the carved lettering with gold paint (nail polish actually).

Then I drove to Marblehead on Lake Erie and bought a new trailer from Islander Marine.  The winch strap hook needs something to attach to.  I planned to reinforce the bow from the inside and put a long welded eyebolt through the bow, and the inspection port hole makes that possible, one more reason I'm happy I cut it.  Unfortunately he winch hook is too thick for the eyebolt I bought, so I exchanged the eyebolt for a U-bolt.  I need to drill two holes but should be even stronger.

In the coming week I plan to varnish the unpainted surfaces, paint the decking white, install the inspection ports, put in the ballast and assemble and coat the flooring.  So hopefully the boat (except the rigging) will be ready, almost to the day, a year after I started.

Then it will be time to set up the rigging, with blocks, cleats, wooden eyepads, metal eyestraps, bullseyes, snaphooks, a minimum of 64 screws, four kinds of line (sail lacing, halyards, sheets, snotters, tack downhauls, painter, anchor cable, miscellaneous loops, etc., etc.), and other fun stuff like knots and eyesplices.  I already bought all the screws I need (it was tricky and I may have forgot something) and a piece of closet rod for the mizzen sprit (I already have one ready for the main) which needs epoxy and varnish.  Also I will put leathers and rope buttons on the oars.  At the very end I will also make a boarding ladder from rope and oak boards.  I think I will tie the top end in a single loop to hang from an eyebolt or cleat.  So actual sailing may not happen for a while, but I hope soon at least to launch the boat, row and scull it, check for stability etc.

More miscellaneous progress

This past week I first finished filleting all the seams along the bottom and the splashguards.  I then installed the mizzen mast step and assembled the ballast box with filleting compound, screws and nails.  You can see the box in the first photo.  It has two narrow compartments, and I will pour 25 lbs (11.4 kg) of lead shot into each, on a bed of caulk, after they get two coats of epoxy.  The ballast box will be covered by the middle floor plank.  In the meantime, the lead arrived by mail.  I wonder how the postman avoided getting a hernia or back trouble: 50 lbs in a small parcel was deceptively heavy and very awkward to lift.

I then measured and cut the cedar floor planks and tried them on for size (see second photo--they are not properly spaced or assembled yet).  The 30-inch-wide cockpit can be covered pretty exactly by eight 1x4 planks (3 1/2 inches wide in actual dimensions).  The part of the floor aft of the centerboard trunk and thwart will have eight such planks.  The forward part, however, has a middle plank covering the ballast box, so there are three planks on either side of that plus one plank ripped in two lengthwise for the edges.  On the starboard side I had to cut a notch into one plank to accommodate the centerboard trunk.  I also cut pieces that will connect the planks on their undersides from 1x2 lumber.

Then I mixed up a batch of filleting compound and did several things.  I put in floor supports on both sides of frame 5 (under the thwart) and on frame 7 (which is the bulkhead forming the aft seat and storage compartment).  The floor support on the main forward bulkhead (frame 2) is on already.  So now there are supports for the fore and aft ends of the two parts of the flooring.

I also glued on the boards for the oarlocks, which are centered 10 inches (254 mm) aft of the rowing thwart.  I widened the reinforcement along the top of the transom by adding another board.  Finally, I finished some details on the rudder and tiller and cut the decorative plywood top for the centerboard trunk.  I am now ready for the first coat of epoxy on the insides and decking.

Slow progress

Last weekend I sanded the masts smooth and tried them on again.  They really look good, but it's clear if you look closely that they were not precision-cut on a lathe.  I prefer the hand-hewn look anyway, it has my handiwork all over it.  I will need to sand them with fine grit and epoxy them, but I will do that as part of a big coating push later.  I also cut the hole for the inspection port in the foredeck (next to the mast hole) and began sanding the decking. 

In preparation for further work on the insides of the boat, and for selling the old trailer, I moved the boat to a cradle I built out of the original building frame long boards and some more lumber.  I won't have to stand on a stepladder and lean over a precariously balanced trailer to do what I need to do any more.  Now that the weather is warmer (although not as warm as we had in the middle of March) I have moved all the tools and supplies back into the garage.

This weekend I cut the lumber pieces for the ballast box, drilled a hole in the centerboard for the pivot bolt, tried it in (it fits perfectly as per plan) and test-fitted all the ballast box pieces and the mizzen mast step, which sits at the aft end of the ballast box against frame 5.  I measured the size of the box and estimated how much lead shot it could take.  Turns out it's under 75 pounds.  Given the weight of the boat without the ballast, I decided that 50 pounds of lead shot is a good amount: it will help make the boat more stable without adding unnecessary weight.  And lead is not cheap anyway.

I also gave every part of the boat on the top and insides a good sanding, vacuumed up all the dust and shavings, and started putting in the epoxy fillets along the inside bottom seams and where the splashguards meet the fore and side decks.  In the coming week I hope to finish all that, build the ballast box, and perhaps carve the boat's name on the rubrails.  Then, after a final light sanding, I will be ready to put on the epoxy coats, and finally the paint and varnish.  It's good to be able to see the light at the end of the tunnel!

Masts planed and fitted



This weekend I planed the masts to a round shape and tapered their ends.  As expected there was a huge amount of shavings.  The masts will need sanding, then two coats of epoxy and at least two of spar varnish.  But before that I had to try to step them to check everything fits.  It took a little extra planing but they both fit well.  I couldn't resist taking photos.  I can now imagine the boat completely rigged, flying in the breeze!

I had said I was hoping to launch the boat on the first warm, sunny day of the season.  Given the crazy weather we've been having, we've already had many warm, sunny days (it is 84 degrees Fahrenheit, or 29 Celsius, as I type, in March, in Northwest Ohio!).  But I still hope to lauch the boat by late April or early May, no more than a couple of weeks past the first anniversary of the first cut.  Wish me luck!

More mast and sail work

Two weekends ago I sanded the oars down to a ready-to-epoxy stage.  Then I finished the scarfing of the mast boards (or so I thought) by doing a lot of sanding.  Then I test-fitted the boards together.  Amazingly, they fit to the right length (except for an extra inch of length on one layer), but some of the scarf joint surfaces needed to be sanded further for a better fit.  I did some of the gluing at one end of each mast (first photo, left side).  I also ordered as much chandlery as I could think of from Annapolis Performance Sailing and Jamestown Distributors.

Last weekend I re-sanded the remaining scarf surfaces, then I finished gluing up the main mast blank (first photo, right side).  While the epoxy was curing, I bought the lumber for the boat's floor (mainly cedar 1X4 boards), and filled the recessed nail holes in the boat's top and insides with putty.  The next day I glued up the mizzen mast.

This week I finished the sails by putting in battens (photo) and reef points.  Finally, I started on the shaping of the masts.  This involved first trimming the laminated piece from 2½ X 2¼ inches to 2¼ square, then cutting the corners off at a 45-degree angle for an octagonal cross-section (last photo).  The rest will be achieved by rounding the eight corners with drawknife and hand plane, then sanding.  There will be tapering from mast partner to mast step, plus a little at the top.  I will have to do all this to both masts before they can be epoxied and varnished. 

The next steps will be:
  1. Cut a hole for an inspection port next to the main mast hole, for access to the space between bow and first bulkhead.   This compartment may have some water leaking into it through the edges of the mast hole.  Rather than build an elaborate mast tube with drainage system, I will simply dry the compartment as needed.  It may also provide useful storage.
  2. Sand the benches and the decking.
  3. Fillet all the joints along the bottom (seat risers and  bulkheads with bottom, and seat risers with frames).  This will improve strength and the water-tightness of compartments.
  4. Build the ballast box.
  5. Put in oarlock sockets and carve the boat's name on the rubrails (in English and Greek).
  6. Lay two coats of epoxy on insides and decks. 
  7. Fill the ballast box with lead shot.
  8. Put in the floor and epoxy the planks.
  9. Finish everything with paint or varnish.
  10. Set up the rigging.
Wow, that's still a lot of work.  In case you are wondering why I often list my next steps, it's mainly for my own benefit: I need to work out the sequence because I designed the boat and the rigging and everything else and I am figuring out stuff as I go along.

So keep checking 176inches as the saga continues.

More planing and scarfing

The past two weeks I have been working on the oars and I started on the masts.  Last week I cut new oar blade pieces and glued together new oar blades.  I used filleting compound (epoxy and wood flour) to glue and reinforce the joints, and put the pieces over a heat register to make sure the epoxy cured properly (first photo).  Once that was done, I did a lot of planing to taper the oar blades to the right profile and rounded their corners (second photo).  The oars were a little heavy, so I decided to round the shafts all the way from where they meet the oarlocks (where the so-called button will go) to the blade.  I did it with drawknife and plane, using only my eyes and sense of touch for guides, and created an unbelievable amount of wood shavings (my wife said, "too bad we don't have a hamster").   By now the rough carving of the oars is done and they will need much sanding before they are epoxied and varnished.  Hours of physical labor went into it but there is something very satisfying about this type of woodwork.


Today I started on cutting the boards for the masts and creating the scarf joints.  I thought I would try to cut the joints rather than spend hours sanding the joints away.  First I clamped together six boards, staggered by 4 inches each, and clamped on a piece of leftover poplar 1X2 as a cutting guide for the circular saw (third photo).  It worked, sort of: keeping the blade absolutely vertical is not easy.  So now I have to finish the job by sanding the scarfs flat (last photo), but at least 80% of the material is already removed.

Then I cut two of the remaining boards in two, using the same kind of diagonal scarf cut.  I got two pieces of approximately 48 inches and two of just over 43.  I got three pieces of 24 inches out of the ninth board, and a 19 inch piece from a bit left over from the my original, abortive oar blade work.  Once again the scarf joints were not cut 100% right and they need sanding to the final shape.  After that, the boards will be arranged in the following way:

Main mast: top layer eight feet plus four feet; middle layer two feet plus eight feet plus two feet; bottom layer four feet plus eight feet.  This will create a mast of about 12 feet, with scarf joints at different places to avoid weak points.

Mizzen mast:  top layer eight feet plus 43 inches; middle layer two feet plus eight feet plus 19 inches; bottom layer 43 inches plus eight feet.  This will create a mast of about 139 inches.

There will be more sawdust flying, clamps tightening and epoxy curing, so keep checking 179inches.

Yards, oars and masts

The sails are now done.  I still need to sew reef points, which involves sewing on square pieces of sailmaker's tape with a buttonhole at the center of each (some people prefer grommets, but I'm good with the machine buttonhole stitch) .  Reefing, for landlubbers, means shortening the sail and rolling up and securing the loose ends by tying loops of line that go through each reef point buttonhole.  Since the leech of the sail is rounded for maximum sail area (this is called roach, again no idea why) I need to use battens to stiffen it, which means sewing in batten pockets made of folded-over sailmaker's tape.  Both these will wait until I order all the chandlery (blocks, cleats, fairleads, rope, anchor, assorted hardware and battens).

Meanwhile I have rounded and sanded the two yards, and have put on one coat of epoxy.  After drilling holes at the ends to tie the corners of the sail's head onto the yard, there will be sanding, a second coat of epoxy, more sanding and a couple of coats of spar varnish.  That will take time, so I started on making the oar shafts, by laminating together two layers of 1X2 poplar, 1 1/2 inch-square (or 37 mm square) in total actual dimensions.  Then I cut and edge-glued the rough oar blades from 1X2 poplar (center) and 1X3 pine (sides).  You can see them in the photo.

While I was tapering the shafts down to the blade's thickness of 3/4 inch (19 mm) with a hand plane, both blades managed to fall to the floor and delaminate into two pieces each.  Better now than later, I think.  Clearly the temperatures, even in the partially heated basement, are too low for reliable epoxy curing.  I think I will take the opportunity to redo the blades.  I originally decided to use pine on the sides for the visual contrast, but pine is probably too soft for an oar blade that could be scraping against sand and stones.  I also realized that the original blades are a little stubby.  So I will make the new ones longer, and will cut them from poplar like the rest of the oar.  I don't mind: remarkably, this is pretty much the first thing I've had to do over in this whole project.  I will have to glue the blades and shafts together with thickened epoxy, and make sure I keep the basement and/or the piece warmer.  Then the blades will have to be tapered to a thinner edge, the corners rounded, etc.  In the meantime I have started rounding the shafts at the hand-grip ends.  Next I will round the shafts where they meet the oar locks, and that part will need leathering and buttons put on--I'll explain later.  All in all there will be even more planing, shaving, sanding and other work before the oars are ready for coating.

In between all this I will also be cutting 14 mast boards and preparing a total of 16 wedge-shaped board ends for eight staggered scarf joints.  Check 176inches for more details and pictures of mast work.
