Steering a course
I've temporarily bolted on the Gudgeons, I'll take them off again to epoxy the holes, and for painting. But I need the Gudgeons for 2 reasons.
1) I will need to go fetch my mast, so I will need the trailer lights mounted, which will mount onto the Gudgeons.
2) I wanted to make up a test rudder.
I was in two minds about a kickup rudder, see the diagram at the bottom of this Glen-l Letter page. And I want to test out my planned method for creating the foil. Both begged for 2nd rate plywood rather than the expensive stuff.
I drew and cut the rudder as shown in the Glen-l Letter, and then made up the cheeks with 6mm ply. I used a large bolt for the pivot. All went very well. I think I'll laminate up 2 x 6mm ply for the cheeks of the final rudder.
So then I went on to the rudder release.... If I hit the bottom I don't want stuff to break, so I tried out one of the Auto-Release Cleats from Duckworks. See http://www.duckworksbbs.com/hardware/cleats/sd002570/index.htm
Be warned, the angle of the lead makes all the difference in the world to how hard it is to pop the cleat. Since my clear was on the cheeks, and the line lead to the rudder, 6mm or so "lower". The line lead "up" to the cleat.
A quick decomposition of vectors later with a pen an paper confirmed that if you lead "up" to the cleat from below, it simply won't pop open, it's not the fault of the design, simply basic geometry. Smacking the rudder off the ground to simulate hitting an underwater obstacle simply dented my rudder (this is a mock up - so that was no big deal.)
I tried a simple sacrificial wooden pin (a disposable chop stick) and I got much better results, but it would be impossible to clean out the broken "pin" and replace it under way. So I need to experiment with the auto-release again, now that I understand why it did not open. (Yes, I had it set to the minimum resistance setting)

It all slots together
There are two pairs of cleats on the frames, and matching cleats on the bottom of the floorboards, so when you drop the floorboards down they have to locate properly and it all ends up like this
If you look at the cross piece on the underside of the floorboards in the top picture, you see it extends beyond the slats, this runs under the centre floorboard which is fixed in place, and helps hold things together.
The boards on each side can then be lifted out by raising the outboard side.
Easier, simpler, and cheaper than stainless steel hinges.
I think a bit of cord and some simple wooden Jam Cleats on the frames should hold them in place. The cord can simply be doubled through a pair of holes in the locating cleats on the bottom of the floorboards. Unobtrusive, cheap, simple.
I really should give things a wipe over before taking photos....

And somewhere to stand
The floorboards are made up of the centre which will be fixed, and the two sides, which which are removeable.
The battens which join the four slats on each side extend under the centre peice to fix them down.
A small batten at each end locates the side forward and aft. And some angled blocks (yet to be added) will locate the floorboards to prevent them sliding side to side.
They are sanded screwed together above, I have to take them apart and add a drop of glue, and then oil them when they are dry.
I'll have either turn buttons, or simple cords to hold the floorboards down on the outsides.

Is that sharp enough
Damn, end grain in Sapele is as hard as a Hamiltonian Path. (really hard)
I think it was Lincoln who said "If I had six hours to chop down a tree, I'd spend the first four hours sharpening the axe", well I sharpened my little low angle block plane till it could do this to the end grain.
Good man Lincoln, with sense like that, he should have been let run the county.
The obligatory birds mouth test
Even with this rough and ready attempt, it came out rather well. Go to Duckworks website and search for Birdsmouth. They have LOTS.
I penciled in the outline of the joints, othersiwe you could hardly see them.

Introducing the Lady Caroline
Now that the deck is glued into place, and trimmed, I can see what The Lady Caroline will look like.
I've just started the seats. I have some filling over the screws & sanding to do on the deck.
It's all coming together.
In other news, my Mom recycled an Old Leather Sofa. I acquired large amounts of the leather. And a short strip of it made a nice strop. Turns out that a scrap of leather with some polishing compound on a backing of birch ply will sharpen up a blade just fine. The more I practice sharpening tools, the more I wonder what all the fuss is about.

The deck is attached.
The entire deck is now glued and screwed in place. It started raining about 10 minutes after I'd finished the aft panel. That could have been a small disaster if the rain has arrived 30 minutes earlier.
I see a router and an edge trim bit in my near future to trim back the over hang on the deck.
I've started work on the seats. The slats look really nice with the deck oil on them. I just broke the corners with sand paper. The wood has a wavy grain, back and forth a few mm every few feet. Fine in terms of the strength of the slats, but running a block plane along the edge is a disaster. 18" of slicing through the grain followed by lifting a chunk.
To bend the slats into place, I've clamped a block to the outside of the seat supports, and reversed a few QuickClamps to make pushers out of them. An extra one vertically placed at each end keeps things from springing loose.
I've just sanded and oiled two slats so far to see how it goes, now I need a more efficient way of doing the remaining 12 for the seats, and 9 for the floor.

A picture during the day
I've rough cut all the panels for the deck. They are all epoxies on one side, the other sides next on the list.
Then I start to glue & screw it down.
You can see the slats for the seats sitting in the boat.
Sorry it's a little... untidy. My workshop consists of two D&B workbenches side by side.

Today I started the deck...
I have already rough cut the 5 pieces that will make up the deck. But now the framing is completed, screwed, glued and dried.
So I've finally started work on the deck proper.
I've cut the backing blocks for the butt joints.
All the main pieces are rough cut and I've gotten one side of each soaked in epoxy. (much easier to do now rather than climbing inside later.)
I've started screwing the fore deck in place and laying out the remaining part to mark them up.
I really feels like I may have a boat soon.

Oak is sharp !
The deck framing is now almost complete. I've one or two dovetails to cut, and I've almost all the fairing done.
One thing that I learned is that white oak chines, when planed, can be sharp enough to remove chunks of skin. You always remember not to have a hand in front of a blade, in case the blade slips. But I forgot that a 60° oak edge is just as much a blade to the soft skin on the side of your hands.
To avoid anyone unnecessarily setting up a "Save Dave" web site, and associated charities to pay my hospital bills, I should say that my hands are still fully functioning, the missing skin didn't require any more than a plaster.
One other thing that I spotted is that before I screw in the last few pieces, It will be a lot easier to measure and mark the coamings. I can cut them to roughly fit, and mark them exactly in place. If I screw and glue the remaining pieces first, then I won't have that option.
All going well, I'll get the coamings and other details sorted this week during the evenings, and start the deck next weekend.

That bit looks big enough
So I wandered out to the boat last night after the munchkins went to bed, and I spent a while looking at the place where a cross member needed to go, and trying to figure out if I could laminate up a piece, since I didn't appear to have a piece big enough. I wanted to avoid another long trip to get one plank, when I noticed a piece that I'd tucked away under the boat a while back.....
Looks just about right, hold it in place, clamp a few bits in place, mark it up, double check everything (all under a battery powered florescent inspection lamp and a head torch) and whip out my Pull Saw. I can now cut compound bevels to a line as accurately as I can see. You got to love pull saws.
(I came across a small article in a magazine a while back about cutting a starting notch for the saw with a stanley knife. Make it 1/4" deep by paring the waste side down, and you have a perfect guide to start the cut.)
I can't fire up power tools late at night, the neighbours would (quite reasonably) be peeved, but no-one seems to mind the nutter with the hand saw and the head torch.
Anyhow, in an hour or so, I went from planing to spend an hour on Saturday cutting and laminating a piece to simply having it cut to length and fitted.
I've marked off the curve for the top of the piece too. I'll run it through the band saw later this week.
I can run the band saw after dark, it barely makes any noise as it slices through 1" of white oak... which is kind of scary in a way. At least a table saw screams a dire warning that's pretty hard to ignore. The band saw just quietly cuts through pretty much anything.

Can we go sailing now daddy?
The Cut.....
So I have 2 pieces of oak, 3" x 1" x 10' for the Carlings. (good luck finding that on Google without coming up with larger, or sports - try "Carling and Deck)
All I have to do it cut them to fit.
At each end, there's a compound bevel. And the wood curves along the length of the boat. So if you don't take account of the curve, it will end up short.
You can see here how you cut the angle to get the length right.
I was accurate to about 1/10" over 9 foot on one side, and a snug fit on the other.
Measuring and marking the wood in place, if you can, it easily the most accurate, and least error prone way of doing things.

Making Sawdust....
The last consignment of wood arrived yesterday, so I took a days holidays to.... get the wood tidied away out of the house.... yes. Get it Tidied....
I have a cheapo shop vac that I can connect up to the power tools, after ripping various oak and mahogany planks into over 20 1", 2", 3" and 4" wide slats, each over 9' long, I had enough sawdust to fill a large kitchen bin.
I now have all the wood I need to finish the boat. All I need now is time and good weather.
I now have to round the edges of over 400 feet of wood. And then Oil it all.
I'm going with deck oil rather than varnish. It's more continuous maintenance, but the maintenance is a lot easier. Just rub in more oil. No Sanding, stripping back to the wood. Just rub in more oil every 6 months and you're done.

A weekend of progress...
I got out my Bevelator 1000 again. This time to bevel the sheer clamps where the deck will go on. I also cut 2 of the three beams that will sit under the foredeck.
The remaining wood arrives over the next week or so. So I should have a deck on the boat in the next 3 weeks.
Then it's the seats & floors.
I found this for making up foils. Nearly as good as a 3d Cad system.

New Toys....
Against the day that I might actually have to sail the thing, I've started accumulating various bits and pieces that I'll eventually need.
I picked up a marine compass a while back, and a last week I came across this http://www.opticron.co.uk/Pages/trailfinder_ii.htm
Note the Inter Pupillary Distance. 58~77mm. For those who can't get a one size fits all baseball hat to fit, the normal ~72 mm IPD on binoculars leaves you with a very cumbersome monocular, with a spare attached.
Many of the other Binocs with a large IPD were Lecia or Swaroski or Steiner, and the prices were quite exotic.
If you are to look through both eyes at the same time, these may be worth a look, so to say.
The are (to my unpractised eye), pretty good, solid, the focus mechanism is reassuringly free of play, and they have a 5 year guarantee.
I don't have any real experience with Optics, so someone more knowledgeable may pour scorn on my advice, but two eyes able to see at the same time is a huge improvement.
I would have preferred the traditional 7x50, but they were ~74mm IPD, and I could not try them out locally.

Snow ?
This is Ireland, we get 3 or 4 flakes of snow each year. That's it. Unless you are up the "mountains" (hills) and you might get enough to make a very short snowman.
This year we had several inches, and real cold. Not the 2 Celsius (35 F) that we usually get, we were getting -10 Celsius (14 F).
I took my 3 year old out on a sleigh. She loved it till she got cold.
People's pipes froze, and burst. Lakes froze over. Some people I work with took 5 hours to get home.
All this means that I have done very little on the boat since I took the pictures.
I've sharpened a few hand tools, and read a lot, but real no progress.

Pictures at last
Monday, December 21, 2009
I’ve started painting the inside.
I’m painting at night, in the cold, with a site lamp and a head torch. I must look even stranger than usual.
