Daggerboard trunk glued up and rear seat glued on

Ok my patient mates, heres some photographic evidence of my work on the boat last week before I left for self-imposed exile at work.

First, I finally got that bedamned daggerboard trunk glued up.  Somehow, I wasnt forward thinking enough, and I glassed up the daggerboard without really giving much thought to how it fit in the already made trunk.  Well, I did but discounted further planing on of the daggerboard and decided that I was done with all the planing and sanding thank-you-very-much and whatever I had, I had.

This was most unfortunate, because I few more minutes of planing would have produced a superior quality board, and it would have fit in my daggerboard case.  So then I was stuck with the project of widening my case, but only by 2-3mm at most because really, all I needed was 1-2mm.

Fortunately, I found 3mm Okoume marine plywood at Goose Bay Lumber, and cut it to fit over the framing for the trunk.  This widened the trunk appropriately.  Here is the widening sequence in pictures:


Very self-explanatory, I think.

Next, I still struggle with the hardward issues for the rudder and transom gudgeons.  I dont know how Im going to get this rudder assembly attached to the boat.  The problem is that the hole to accomodate the tiller does not have the vertical clearance required to use a gudgeon-pintle scheme, which is by far the most convenient.  I toyed around with it and thought about enlarging my tiller-hole, but my pintle arms didnt fit around the rudder cassette.  A second order of larger, more heavy-duty gudgeons for rudder and transom fit great, except not with each other, and the arms were too long for the spacer in the cassette... A rod pushed through the gudgeons would not have fit cleanly and I would have had a clunky feeling rudder, the round peg in an oval opening thing, if you can visualize that.  So I still sit, wondering how I will fix this conundrum.  Many people have done it successfully, but Im still hunting around for the best hardware.

Because of all this drama, I have delayed gluing on the rear seat.  I got tired of having it loose, and glued it on before I left.  Here, yet again, is my "Forest of Bricks" holding it all down.


And the gratuitous parting shot:

Quick Fair is amazing!

HOLY BALLS its been a long time since my last update.  Work has been eating me alive, folks, eating me alive.  Im actually home now for more than one day, so I can update this blog, and work on the boat, but in the reverse order because the boat comes first.

Several weeks ago I ordered some Quick Fair from the fine folks at Duckworks.  This stuff is A-M-A-Z-I-N-G.  Its well worth the money.  It mixes easily, quickly, with little fuss.  It applies itself with astonishing ease, especially using a plastic spreader.  It dries quickly.  It sands easily.  I made several corrections over time as I got used to the stuff and ended up with a chine that is-- wait for it-- very fair.  It filled in the little weave bumps left over from the fiberglass tape, it nestled into the ridge between the tape and the hull that hadnt been filled with epoxy, it filled in some holes, and it faired out the gap between the hull and the stem-dowel-thingie.

I am in love with Quick Fair.  To boot, it even looks like chocolate pudding, except if you ate it, you would die.  The smell tips you off to this.  It smells, bad.  I used my respirator.

I also bought a little digital scale for twenty bucks at the local pharmacy.  Its a "The Biggest Loser" scale, named after the TV show, I believe, I wouldnt know because Ive never seen it in my life, but the box talked about it.  This made mixing the Quick Fair in the appropriate manner mucho-easier, because frankly, theres no way to tell how much you have.  It doesnt pour into a graduated cylinder or anything like that.  I am also using this little scale with my epoxy, and it cuts down on waste.  Another "shouldve thought of this a while ago..." moment.



Heres my chine, needing some serious fairing, including little holes in the fiberglass tape that sanded out because there was air trapped underneath and Hand of God seriously pissed:


And bingo!  Quick Fair to the rescue!



Heres a progression of working around the stem.  Slop it on, spread it out, sand it, touch up, presto!


Oh boy!

For all your fairing needs, Quick Fair is the way to go.

I watched this video for some very good tips.

Rudder design 4 daggerboard glassing

After many trips to the hardware store getting stainless steel carriage bolts and machine screws that were often the wrong size, I finally got my rudder box together in some sort of usable fashion.  As my intrepid readers may remember in three other previous posts (search in the month of March), I have been trying to figure something out in order to get my tiller to be detachable.  I went with the final option, illustrated in this post. 

The rudder box is glued up but not glued together.


As you can see, I am wearing my camo Converse sneakers.  Very cool.  The original tiller design calls for the tiller to be permanently attached to the top of the box, where my shortened tiller stock is now-- so originally that would be much longer, but permanent.  This way, I can remove the tiller and leave the rudder in the water, freeing up open space in the boat during quiet times.  I used a carriage bolt with a butterfly nut tensioned by a split washer.  Dont drop it, and carry a spare! 

The spacer is as of now temporary, but I could do one of three things.  I could lengthen the spacer to make it full-tiller length, giving the tiller laminate strength; I could shorten the spacer; I could make two evenly spaced spacers, I could leave it the way it is.  This is yet to be determined.  Heres a closeup for the interested:


Im having some serious problems with my hardware for the rudder, unfortunately.  I wanted a pintle and gudgeon style assembly, but my 1.5" gudgeons are not fitting around my rudder box, even though its 1.5" wide.  Something aint right.  Also, Id have to expand my tiller access hole in the transom to accommodate the up and down motion to get the rudder in and and out.  So Im scraping the pintle/gudgeon idea and Im going to go with the gudgeon/gudgeon idea, as the original plans stipulate.  Which means I have to find some sort of long pin to thread between all of them.  Boo to that. 

Also today Ive been working on my blades.  My rudder got sanded down to the matte finish, and I carefully taped off vertical areas that would run, and applied one last thin coat of epoxy onto one side of the rudder.  Tomorrow, the other side.  I used a plastic spreader, and it went very well, very smooth, and Im very happy with my luscious result:


Youll notice on the left hand side that the leading edge still isnt coated, this was taped off earlier.

Then, off to glassing my daggerboard!  Much like the same for the rudder, except I cut a bigger piece.  I had a lot of runs in my rudder, and I figured this time I would lay the board flat, spread epoxy with a squeegee, and then turn it over, do the other side, and then hang it up. 

So I went ahead and did one side horizontally:


 I thought I was being pretty smart. 

So then I turned it over and did the other side.  Something caught my attention and I looked underneath my board and...

... well I didnt take any pictures because needless to say the whole first side has very neatly peeled away from the board, thanks to Mr. Theory-of-Gravity.  Gravity is only a theory by the way, they should teach both sides in schools so kids know this, because there is lots of evidence that gravity does not exist, but "they" dont want to show you it.  I digress.  Today, gravity was obviously working quite well.  I finished the job at hand, and then hung it up, and re-spread the cloth down.  Fortunately not much damage done, but for my smartness, well, not so smart now.  Here it is all hung up to dry:



Its late, Im still periodically coating the board to get the weave filled, and Im tired.  I timed this one bad.

Thanks for reading!

New post!

With nothing in it!

Work on the Goat Island Skiff has been temporarily stopped due to a return to work/on the road status.

I have pictures of some work I did just before I left, but they are unfortunately inaccessible at this point in time.  Stay tuned until next week!

Daggerboard case intallation spars

WELL Im on a schedule where Im home about 48 hrs a week, which means 47 hrs of boatbuilding, and 1 hour of laundry.  Not really.

So during my past 48 hrs home I got to it and was able to install the daggerboard case and I hit on a major find for my spars.

For starters, I dragged my boat out of the garage into the driveway and noticed a pronounced twist in the stern.  This.was.bad.news.  If the intrepid reader remembers, I glued down my rear seat last time, and gluing down the rear seat definitely locks in and twist into the hull.  Because of this I was super super careful to make sure there was no twist when I glued it in, using a level and some strategically placed buckets.  I ran outside and moved my boat... and the twist was still there.  There was no way I was going to get any work done if the boat was twisted.  Using some brute force and a rigid vacuum tube I rolled my boat to the pond and threw it in the water.... and she floated straight as a die.  No twist.  PHEW!!!  HOLY HOT HEART ATTACK BATMAN!

Back out of the water, I did some sanding in the interior of the hull to make it easier in the future, and went around installing the daggerboard case.  What is most important is that the case is straight.  If it comes off-kilter, Ive got a giant blade dragging me off into some obscure direction that Im going to counteract with the rudder, and its going to be drag city.  In order to make sure that the case is straight, I stretched a string from the center of BH2 to BH3 over the top of the case.


So here it is, mocked into position with my centerline string.  I tried at first to do this on the ground, but I got much better results up on the buckets.  I think the runners are slightly different and offering tweaked ground handling characteristics.

I cut the ribs for the front of the seat amidships.  They actually came out ever-so-slightly larger than needed- a mistake- that ended up helping me out in the end.  When I put the case into position it would slip around with the oversized rib, I could gently cajole the case into position which was verified by the string.  When everything was straight, I carefully clamped everything into position.  Youll notice the square behind the ribs next to the case to increase gluing area.  The port rib is a little higher than it should be (remember, they were a tad oversize) and Ill plane it down level for the seat installation.



This whole skeleton will be glued together by the center seat.  This, with BH3 and the forward ribs will create the lever that will hold the case in place.  Remember, when I capsize, Im going to be standing on the daggerboard to right the boat, with all my pressure on the case.  This massive gluing area will keep it from ripping out when Im in the water in the middle of nowhere.

Here are two shots of my daggerboard case lined up with my string.


In other news, I went over to Goose Bay Lumber to grab some Doug Fir 1x4s so I could glue up some spars.  I had come up with some crazy idea to put the spars together as a laminated structure since I didnt think Id find blanks that were large enough.  I did.  I found some finished 2x6 DF boards that were 20 feet long.  I had them cut to 12 feet.  A quick rip on my table saw, and I had two skinny blanks and one fat blank.



The spars are on average 40mm diameter.  I get 37mm with the blanks.  My spar is about 37mm x 40 mm or so.  Ill keep it like this for the length and not taper it.  Its kind of bendy, and I need some bendy up at the top of my sail, since I hear that the Duckworks sail can be a little flat.  This should help.  My boom will be 37mm x 50mm or so.  If these are too bendy, I can laminate some ply at key areas to stiffen it up.  This was a quick, easy, and totally suitable solution.  Easy!

Until next week, intrepid reader!

The Unlikely Voyage of Jack de Crow

Since Im on the road all the time, I tend to do a lot of reading to pass them time.  This is good, but its also not-so-good as I get to daydreaming about my unfinished Goat Island Skiff.  However, sometimes a book comes along that not only motivates, but helps embellish daydreams and pass the time.

I just finished reading this whimsical adventure book, and I highly recommend it to my fellow small-boat aficionados.  The author takes his 11 Mirror Dinghy from Northern Wales in England, down to the Channel via rivers and canals, then crosses the Channel into France.    Once in France he sails and rows his way across the continents surprisingly extensive canal and river system until he gets to the Danube and takes it to the Black Sea.  Filled with fantastic literary references (hes an English Lit. teacher), sailing, rowing, high adventure, and out-loud laughing points, I enjoyed this book immensely.

This book gets me all the more excited for my Super-Secret Summer Adventure that I am planning in my Goat Island Skiff.  Tally-ho!

Mast glued up rudder and daggerboard glassing

Ok, another frustrating boatbuilding day here in New Hampshire.

The mast got glued up today in a long session.  It takes a deceptively large amount of glue.

First, I laid down the mast ladder frame, with the two sides to be glued next to it.  I primed the wood to be glue with unthickened epoxy, and then made up the thick stuff.  Application of the glue went along the base plug, narrow staves, and ladder framework.  Afterwards, I picked up the ladder section and placed it upside down on the wide stave.  The other side of the ladder was then glued up and the wide stave dropped onto that, making a sandwich.  Mr. Storer recommends a clamp every foot.  I only have 9 clamps that can be used on the mast.  Mr. Storer advises his customers to use packing tape... use a clamp, wrap the mast with packing tape to hold the pressure, move on.  This method has been used by other Goat Island Skiff builders, successfully.  It kind of worked for me, but not to the degree I would have liked, the clamps hold more pressure.  Regardless, better than nothing, and with some careful maneuvering I was able to make sure that all gaps were closed up.


It took longer than I thought, and a lot more glue than I thought.  There were a few areas where I really had to force the staves into position, and this was a pain.  For some reason I dont have any real overlap in the lower half part of the mast or I could have used nails to hold it in place.  I used my muscles instead, and clamped them down, and hoped for the best.  In  a few locations theres an overlap on one side and an underlap on another... not much, about 1mm, but I see it, and it pisses me off.  I should be building to tighter tolerances by now.  I dont know if its impatience to get this done with, or its a level of meticulousness that drives me batty.

Off to check the bottom runners, shall we?

Oh look, gaps!


 In my quest to use less glue (I keep throwing out tons of squeezed out glue) I went with what I thought was a moderate amount of glue... but it obviously wasnt enough.  These are, surprisingly, my worst scarfs on this boat yet.  This is not the end of the world, I can force some glue in there, they are not necessarily under pressure (that would compromise the scarf) and they will fully glued onto the hull.  So this is not the end of the world.

This is:


My daggerboard.  What a mess.  I was so concentrated and focused on making sure I got it smooth around the end of the board, I didnt really care what happened along the edges of the glass.  I figured I could sand it smooth later.  Now, Im realizing I really screwed myself up the wazoo.  This clean up job without going through the soft wood of the board is going to murder my day tomorrow.  UGH.
