Ready for the next deadline

Posted in Classes on April 29th, 2007

plus equals about how close we got to missing our deadline. Phew. Not that it would be huge deal, the price is that you have to come in an hour early every day for a week, but we prefer to have that be voluntary.

In the past few days we finished fitting and painting the sole

and now the inside of the boat is a consistent, boring shade of Beetle Gray. We’ll have all our fun with color on the deck and hull. Read the rest of this entry »

Brief Interlude

Posted in Newport Life on April 28th, 2007

If you don’t live in Rhode Island I’ve heard that you won’t know about the following thing:  Coffee Milk.  Like Chocolate Milk, only with coffee.  I just discovered this stuff the other day and I’m here to say that coffe milk and a bagel in the morning makes everything good and right.

Wow.  Who knew?

IYRS is nothing if not a monument to the romance of building wooden boats.  When you throw in a foggy day like it’s been today, it only adds to the charm of the place.

Out back by all the old Beetles waiting to be restored.

The pier alongside the Coronet building.

That’s it.  Coffee milk and fog in Newport.  The foghorn on Jamestown Island sounding every 15 seconds.  This is a pretty great place to be.

Secrets to happiness

Posted in Classes on April 26th, 2007

A while back, I left it up in the air about what the final decision would be regarding the mast: does it get a Dutchman or does it have to be remade completely? Well, here’s the photographic answer:

Woo hoo! That’s a jig for making a very straight slot in the mast so I could put in a Dutchman. This is exactly the kind of thing that I love to do: to come up with a way to save materials and time while working out an interesting problem.

The real challenge was to lock in the mast so that it wouldn’t move while I ran the router down its length. If you look at the very top of the mast there, you can see 2 little blocks wedged into either side of the top. Those hold the top centered and straight. The box around the mast is just a track for the router sled to ride on. It worked very well, and I got a nice 1/8″ slot straight down the mast along the epoxy joint. Looks like this:

Add in a spline of sitka spruce and you get this:

It came out nicely. Epoxied that puppy in, planed it down to just barely proud of the surface of the mast, sanded everything round, and it’s just right. From start to finish it took about 2 hours. Compared to the time and materials it would have taken to build a new one… that was a total bargain. For some reason I didn’t take a photo of the finished product. Later I reckon.

So, secret to happiness No. 1: find something interesting to do that will save you time and materials, and then do it. Read the rest of this entry »

Monks, monking around

Posted in Builders on April 24th, 2007

One of the unexpected side effects of this blog is that I get to hear about other interesting boat projects from folks who stumble onto the site. For instance, Glenn in Alaska has been working on a 1953 Bristol Bay gillnetter with a really cool transom:

Here’s to BB Twelve, and another labor of love.

There’s this whole world of folks working on their boats, or their programs, or something else that they love, sharing what they know freely to anyone who happens to bump into them online. This open sharing is one of the ideals that the net was created to promote, and I feel proud and lucky to be able to add a little something to it.

Makes me think of a story I heard about monks begging in India. The monks only own their robes and begging bowls, and every day they live on whatever people give them. The monks say that they’re doing a service to the community, because when people give something, they know that they’ve made a difference in a person’s life. That’s the gift back.

We’re all monks on this bus.

Curvy little joints

Posted in Classes on April 17th, 2007

I’m forever amazed at how tricky some of these seemingly simple joints are. That amazement tends to come after I’ve screwed up a piece and didn’t see it coming. There’s a big “HUH…” squinty eyed look, like the part has just told you something you don’t quite believe. What the hell, I measured you, I cut you accurately, what do you mean “I don’t fit??” That’s just crazy talk.

Everyone says that the tough thing about building a boat is the lack of right angles. Personally, I think that’s one of the most interesting things about it. In some cases, you can work out and mark the cuts you’re going to make ahead of time, and in other cases, you have to look at the part carefully and make little marks on it to guide you in what is essentially free-handing when you plane or chisel. Today was a little of both. Let’s start with the Carlins.

Ok, you totally saw that coming.

The Carlins are the longitudinal supports that attach to the ends of the short deck beams around the cockpit. They help support the little deck there. Just looking at them, you’d think, what a simple thing. You cut the piece to length, maybe bevel it a bit, and screw it to the deck beams. How easy is that?? Here’s the starboard carlin clamped above the short deck beams.

A few things are worth noting here.

  1. The carlin curves outwards to follow the curve of the boat.
  2. The carlin also curves upwards slightly as it goes fore and aft to follow the sweep of the sheer.
  3. The carlin also remains roughly plumb as it curves (the inner face stays straight up and down)

Since the carlin curves outboard, you can’t just sit the rough carlin on the boat and measure how long it is. The curve adds some length. Cut it by laying it out straight and you’ll be about 1/2″ too short. Also since it curves outward, the surface where it meets the long deck beams forward and aft are not 90 degree cuts. They’re beveled (you can see this by curving your fingers slightly and holding your fingertips against a flat surface… they don’t meet at 90 degrees), and you have to figure out what that side-to-side bevel is.

Since the carlin curves upwards as well, there’s also a top-to-bottom bevel that has to be taken into account.

Since the carlin ends up plumb, you have to keep it plumb when you pre-bend it to work out your bevels. The carlin is resting on curved deck beams both fore and aft as you’re doing this (you can sort of see that in the above photo) and it doesn’t Want to stay plumb. It wants to sit on the curve of the deck beam. Also, bending the carlin in 2 directions makes it want to twist out of plumb.

Now we’re having some fun, eh? Read the rest of this entry »
