Seat Blocking Kind Words and a Testimony

Seat blocking & angle finder


My planer / jointer & a bunch of shredded mahogany

Seat Blocking?
Yesterday, I made the 2 pieces of blocking that will go under the ends of the rear thwart. Thanks to my angle finder, I knew the bevel on the blocking needed to be 15°. I cut that bevel by adjusting the fence on my planer / jointer, and running the pieces of mahogany (roughly 12” x 2” x 1” each) over it a few times. Everything looks like it should fit just fine. I’ll trim the pieces of blocking down about a half inch or so, before actually installing them. 

The next step will be to remove the seat and attach some reinforcing pieces to the bottom, in an effort to straighten out the slight bend in the plywood. 

Kind Words
?Earlier in the day yesterday, I had attended a funeral mass for a friend’s mother. I’m not very familiar with Catholic services, and I was sitting in the back with others who weren’t really sure when to sit, stand, or what words to repeat. Some people can feel pretty uncomfortable about that, but I find the awkwardness a little fun. Some of the rituals of the mass were similar to Episcopal services I’m more accustomed to, so it wasn’t entirely foreign to me. But ultimately, such ritualistic expressions are not the main point. “Religiousness” and “faith” are two entirely different things. 

That was on my mind as I walked through the narthex, greeting old friends… many of whom I haven’t seen in a long time. One of them, who knew a bit of what I’ve been through as far as divorce, heart surgery, and other things, spoke the kindest and most affirming words to me that anyone has ever spoken. I was entirely humbled by the man’s eloquence and consideration. I was not worthy of it. 

What totally floored me was when he said that, whenever he faced difficulties or hardships in his own life, he thought about me; that in doing so, he found inspiration in separating what really is, and what really is not, worth worrying about. I was speechless. I was even more speechless when he gestured toward the altar, with the crucifix on the wall above it, and said that he had no use for the supernatural, but instead found inspiration in other people. I understood, because I knew that my friend is a devout atheist… Just as I professed to be for the majority of the time he & I have known each other. 

What changed? 

I thought of the words of Peter: “Be prepared to give an answer to everyone who asks you a reason for the hope that is in you.” All I could do was gesture back toward the crucifix on the wall. 

A Testimony
Don’t worry. This is a boatbuilding blog, and not a platform for proselytizing or shoving religious agendas in anyone’s face. Of all people, I completely understand how irritating that is. I just wondered, how would I share with my friend who I admire and respect, the reasons I had gone from sharing his very same viewpoint to the one I hold now? 

For one, there is this: Most atheists I know are very sensitive to notions of right and wrong, and are almost all advocates of kindness and social justice. From a humanist standpoint, I began to ask myself, “Where do all these sentiments of knowing good from bad, right from wrong, come from? How and why are these sentiments so innate in most people?” 

You may have also heard the expression “there’s no such thing as an atheist in a foxhole.” True enough… when most people are pushed to points of absolute desperation, why do they say phrases like “please, God… don’t let this be.” Is it only an expression? If so, why is it so instinctive, even for the non-believer, in those most desperate moments? 

Also, I began to question why I had such a disdain for religion. After a lot of honest self-examination, I realized that I truly did not have a problem with a God… if there was one. Instead, I had a general disdain for “christians.” You know — those hateful, rude, self-righteous people who express their moral superiority over everyone else & tell the rest of the world they’re going to hell. Those people. 

I have come to believe that “those people” with “that attitude” have done FAR more to alienate people from faith than they have done to share it. 

So, at a point in one of my darker moments during the early stages of my divorce, I made a decision. I decided I would discard EVERYTHING “those people” EVER told me about God. I decided to discard every sermon, from every denomination…. every shaking, judgmental finger that had ever been pointed at me. I jettisoned it ALL. 

I realized that, throughout much of human history, during times of the most corruption and evildoing in the name of God, “the church” held the power of one particular point of leverage over common people: Literacy. 

Much of human history has been filled with unwritten, average, everyday people who could only dream to read. These people had to rely fully on “the church” to explain the words of the bible. With the power of literacy and the fear of a wrathful God in their hands, “the church” gained an almost absolute power over common people. 

Today, we largely take literacy for granted. I realized that my impression of faith had largely been based on what I had seen and heard from “those people,” and NOT what I’d read for myself. My impression of faith had also been formed by things I’d heard and read from vociferous opponents of religion, and what THEY had to say about the bible…. NOT what I had read for myself. I had absorbed everyone’s opinions but my own. Maybe it had just been easier that way. 

In any case, I decided to change it. 

I discarded everyone else’s interpretations, explanations, and opinions of the bible. I bought one, and simply began reading it. It was a turning point. 

Have a great day.

False battens blocking for deck framing and shiny stuff

Trying to push this project on toward completion, tonight I started measuring for the deck framing. So far, it has been mercifully simple.

I clamped my big adjustable T-Square onto the forward frame at the centerline, and measured the halfway point between the frame and the breasthook. Then, I set my 48" ruler across that halfway point, at right angles to the T-Square. After determining the rulers contact point with the sheer was an equal distance from the frame on both sides, I clamped the ruler into place, and marked the sheers. Then, I measured the angle at the intersection of the ruler and the sheer. Thankfully, it was a very easy-to-cut 20°. 

Measuring for the deck framing.

The blocking for the deck framing required a simple 20° cut. Here is the starboard side being epoxied into place.

Blocking for the deck framing on the port side.

Here, the false battens on the floor are being epoxied into place. All those boards look a little excessive to my eye, but the false battens do serve a practical purpose.

Tonight I drilled the holes & installed the stainless steel grab handle on the forward frame. The first time I rode in a Glen-L Utility, I realized this is a "must-have" item.

Progress...

Seat blocking epoxys love affair with tape

It has been a busy week with band rehearsals & back-to-school shopping, but last night I did manage to get the blocking for the rear seat attached.

I had covered the ends of the seat with blue painters tape in an effort to keep from gluing the seat down just yet. In short, it worked. But, after I had pried the seat off of the blocking, I was reminded that epoxy really likes blue tape. Epoxy likes blue tape a lot.

Thats a mess to clean up another day.


16 clamps to install 2 pieces of seat blocking? Yep. Some to clamp the seat to two levels; some to clamp the seat to the center support; some to clamp the blocking to the seat; and two used as spreaders to push the blocking upward & outward.




The larger Irwin bar clamps are great, because you can switch them around & use them as spreader bars.

Port side blocking attached.

Starboard side blocking attached.

No, I wont win any prizes for fit and finish. (Im not trying to.) Even with the imperfect fit, the thickened epoxy is tenaciously holding the little mahogany block to the side of the boat.

I can fill in the remaining gaps with epoxy when I encapsulate the inner surfaces of the hull.

Eastern Arctic Kayak Construction Blocking in the keelson

My last post on the EA kayak, probably should be called EC kayak for Eastern Canadian kayak, mentioned that I blocked in the keelson.  But I didnt have any photos yet.  Now I do. 
This view shows the pieces of two by four that hold the keelson at the desired distance from the deck. Pieces of rope hold the chunks of wood in place.
Heres an overview of the entire assembly.  I installed a block of wood at each deck beam.  I usually do this since when I install steam bent ribs; they push up on the keelson and distort its shape unless I lash the keelson down very securely. But in this case, the ribs will be flat and exert no pressure on the keelson and so would not need all this blocking. I kept the keelson pretty straight.  Regular EA kayaks have some upsweep near the stern to let the kayak turn into the wind when the hunter is approaching game.  But for recreational kayak, turning into the wind is an annoyance and not an asset and so I have chosen to keep the keelson straight.
Heres a view of the setup for an EA kayak. The rib blanks have been inserted into their mortises and await bending.  The height of the ribs will be judged by eye and the keelson wont be added until all the ribs are in place.  This is probably more efficient than what I am doing if you know what the bottom profile of the boat should look like.  I imagine they bent a few key ribs and filled in the rest for a smooth transition between them.

Blocking

The keyword for the current phase of the build, I suppose, would be "blocking."

"Blocking" is the term to describe the little pieces of wood that you add, here and there, to support or reinforce "other stuff," such as: 

  • seats, 
  • deck framing, 
  • and in the case of this post... the quarter knees.

The blocking for the quarter knees, like the quarter knees themselves, are cut from 3/4" mahogany. This blocking will also provide support for the transom handles Im planning to add later. 

To attach the blocking, I simply used epoxy thickened with #2 silica. 


Blocking for the port quarter knee.

Blocking for the starboard quarter knee.

Starboard side, with the clamps removed.

I used the extraneous thickened epoxy to fill holes and gaps here and there. This is the sheer-to-transom junction on the port side. Here you can also see a cross-section of the overlapping fiberglass cloth on the corner.

I filled in this little gap on the transom, near the motor board. This may be "marine grade" Douglas Fir plywood, but its obviously not made to BS1088 standards. (The outer layer is 1/4" BS1088 Meranti.)

Small gaps filled in around the top of the transom knees.
