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.

Rudder and daggerboard ready to be shaped mast lumber!

Today was a surprisingly uneventful day in the my personal Goat Island Skiff world.  Ive been stumbling around lately trying to get traction on a number of projects, some held up by other projects that needed to be completed.  Two large steps forward happened today.

First:  I wandered into Goose Bay Lumber haphazardly and found 4 pieces of 20 x1x4 finished Douglas Fir boards.  All of them were straight, maybe three knots in the bunch, and relatively nice straight grain to boot.  Just four, all four were good, I grabbed them.  These will be my mast that powers my vessel.  I had them cut to 15 8", since the mast is just a smidge over 15 6" tall, this gives me an inch of "oof" space.  Also, they had a 15" planer, I had my daggerboard, and we fed it into the mouth of the machine.  It spit it out a little thinner, and nice and smooth on one side.  The planer was not a precision machine, and while I can lose 0.75mm, Id rather do that by hand than take out a huge chunk or something.  But it helped.

Second:  I called my bro-in-law and he was home, with his 13" planer.  I strapped my mast bits onto the roof of my sedan in a fashion that screamed "I will impale the person in front of me if you rear-end me" and roared up the interstate to the second planer.  In short order I planed my rudder down to the requisite 22mm and it came out amazing.  Then, away I planed my mast stock down to the 1/2" it needs to be.  Back on the roof with a little less mass and a little more wobbliness and back to my garage where I trimmed the trailing edge of my blades and got them ready for shaping.

 

Heres my mast stock. Hmmmm Hmmm delicious stock.

 

So I need to shape the rudder, to make the rudder box, so I can install the rudder hardware to the boat, so I can finally glue down the rear seat.  Then, daggerboard so I can glue down the centercase.  Then, make the mast, make some spars, and then I can start finishing my boat.  One day, one step, at a time.
