August 2,

I really got in quite a bit of work over the weekend.  There was a lot to work out and I've made good progress.  

Time to buy a new dovetail saw.  I had to work way too hard keeping the cuts straight.   That poor saw has cut way too much oak already.  

The cut is a little messy.  I actually had to redo this and managed to do a much better job but I did not get a picture.  Notice how the cut is off the line at the top.  

Not too bad.  Needs a little cleaning up with the chisel.  This is also one that I ended up redoing.   I really wish I would have taken a picture of the actual one I installed.  It was much nicer.

It fit perfectly with only a slight tap of the wood mallet.  This is the second time I installed this beam.  If you look at the top right in the photo, you will see where I had to cut it out an move it.  I installed it in the wrong place the first time.  Lost about 3 hours of work but like I said above, I did a much better job this time.  Practice makes perfect or near enough.

That's a pretty tight joint.  

One of the corners where the cockpit narrows forward of the wheel station.  A nice 3" (7.5 cm) radius.

This is where this will actually go.  Checking fit.

Everything is tacked together with sheetrock screws as I temporarily build out the cockpit.  The horizontal plywood in the center will eventually be a sealed but removable hatch for installing and removing the engine.  Maintenance access is elsewhere.  There is an 8" step from the rear cockpit to the forward cockpit.  That odd looking piece of plywood sticking out is a spacer and will be replaced by the rear cockpit floor at some point.

The removable engine hatch temporarily put together with drywall screws.  I've rounded the  edge in front because that will be the top corner of a step.

Some more progress this weekend.  A lot that wasn't particularly picture worthy but basically I'm working out the cockpit framing.  

Top of bulkhead framing,  Now that it fits tight, I'll mark and cut the curve for the top to match the bulkhead.  I've cut down the corner blocks and notched them for the framing.  

Sometimes you come across a piece of wood so pretty that you put it aside to use on the interior where it can be enjoyed.  This burly white oak is too tough for my plainer.  The burl is still rough.  I'll have to sand to finish.  It's a 5/4 board about 6 1/2 feet long and near 8 inches wide and burly most of the length.  Not sure where I can use it but I'll find a place.  

My next task is to complete the cockpit framing and temporarily install the plywood sides and bottom.  Temporarily because I want to be able to remove all of that obstructing material in order to build the rudder controls and bore for the rudder post that will come up aft of the bulkhead shown in the middle of the photo below.  The wheel shaft will power the rudder post via a simple worm gear.  No chain and rope complications.  The downside is that there will be no feedback through the wheel.  Some would call this a plus but I'm more use to tiller steering and like to feel what the boat is doing.  With no feedback, I will have to rely on wheel position to know how much weather helm I have.  The self-steering vane will have to be an auxiliary rudder type off the transom.  On the plus side, the self-steering vane can double as an emergency rudder.   It's a tight cockpit, but everything will be within hands reach for single handling.  This is a very important safety measure.  I want to make sure that if one of us is unable to sail, the other will be able to handle the boat at minimum with the staysail and main (both self tacking).  

The rear of the cockpit.  The port side longitudinal is installed.  The starboard on is just laying in place.   The cockpit is a shallow "T" shape with the top bar of the "T" aft and 8" lower that the forward part.  You can see the step and the forward part in earlier photos.  It is all removed here so I can get around better.  The aft part will have to be actually installed first.  I needed to work out the forward part first in order to figure out what I want.  Everything in a boat is connected and you have to be very careful in the assembly order or you'll make yourself a lot of extra trouble.

I got that starboard longitudinal notched in and glued.  It went fairly easily.  My dovetail saw that I use for those notches is starting to cut a little crooked.  Seems like one side might be a little dull or the kerf is off.  It's too small and too inexpensive to sharpen and it's time for a new one.   I have two and the other is too dull to use.  I might have hit a screw with it and thats the real issue, I don't want to spend money on an expensive one (100$) because I might hit a brad or screw.  The ones I have are made by Stanley and work really well but no one in my town carries them anymore.  The closest I can get is offset handle flush cut with shark tooth teeth.  I guess I'll have to order one.   This is the one I ordered: https://www.amazon.com/gp/product/B001V9KOFA/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1

I'll let you know how it works.

Addendum October 12, 2020:  That dovetail saw above has a handle that will not fit my hands.  I ended up reshaping that handle to something a bit more uniform.  It still turned out to be a very marginal saw and a waste of money.  I guess I'm going to have to spend the big bucks and buy a real saw... another $100.  

I also worked out the main cockpit and made the framing members that define its shape.  The sides are angled just so that the angle between the deck and sides are 90 degrees.  The front and back are straight.  The front being the bulkhead shown above and the rear will mostly be the helm seat and foot rests.  I'll have all this temporarily put together shortly and I'll be able to sit where the helm will be and see how the site lines are.  From what I can tell so far, I'll have a clear view over the cabin deck house and can easily see the entire bow.  

The is the cockpit section of the boat.  The hanging frame off the curved beam in the middle is the aft end of the cockpit.  I've secured the joint temporarily with square gussets.  Later a beam will run from the hull framing across to the other side and locate and secure that framing and also act an attachment point for the 3/4" plywood that will make up the cockpit.  You can see the framing duplicated on the bulkhead to the right.  

I've added the structural beam across the bottom of the cockpit attached to the hull with a short pice of wood spanning two of the hull longitudinals.  The temporary gussets are removed. The piece of pine in the middle of the image temporarily holds the framing at exactly the right place.

Same as above but starboard side.

looking at the rear cockpit framing from above.  

This will almost be my view from the helm.  The camera misses a bit but I can see most of the deck forward of the cabin deckhouse even when the deckhouse is finished.  The deck house is surprisingly low for minimum windage.  The more I learn about boats the more I anticipate this boat being a real nice sailer.

Worked on the deck framing at the aft end this weekend.  

A right angle drill to get between the floor boards and drill limber holes to let bilge water through.  I suspect this will come in handy in other places as well.

Most of this is temporarily put together with drywall screws.  You can see I put back the forward cockpit area.  I have to make the side rails which will double as a seat hatch bracing. 

I spent some time planning my next project this morning.  I'm putting together a new laminated beam that will go just forward of the bulkhead at the top of the figure.  The one I made is 5" (12.5 cm) too short.  I had assumed it went between the carling supporting the deck house but on close inspection, the carling actually goes through it.  It is an extra large beam 2"x5" (5 cm x 12.5 cm) that will support the aft end of the deck house.  I'm going to use the too short one for the back of the very same bulkhead.  The beam stops to the left and right of the narrow cockpit area so being too short is not a problem since I'm cutting out a big middle piece. 

I'm trying to proceed carefully, I've just caught myself about to make a few mistakes.  I do not like making mistakes, they cost time and money.  So far, I'm very happy with how everything is proceeding and I'd like to remain happy.

Fitting the last full length deck beam.  This is 2" x 5" laminated full length beam that I'll try to dovetail into the sheer clamp.

More complicated than I thought.  You can not fully cut out the dovetail because it does not got all the way through the beam.

You can see why it was a bit more complicated here.  Looking good so far.  A little clean-up and this should work well.

Success!  

Another angle.

Nope, there is never a square cut on a boat.

The other side is done as well.  Now I just have to cut the female matching side in the sheer clamp.  The lines above the dovetail are reference lines.  It's doubled here.  I used an electric saw to cut the mostly down the end.  This is a compound cut and I cut it long the first time to make sure the angles were correct.  Actually, one of them was a little off so after making an adjustment, I used the correct reference line and was able to cut the compound angle perfectly.  Well the skill saw used could not cut it all the way so I had to finish it with a hand saw.

I used a 3x5 index card to make a pattern for the dovetail.  I also measured and those are the lighter lines.  The pattern is more correct.  

The dovetail required a little clean up with the chisel but by the time I was done, it was a very tight joint.

Nice fit.

Not too bad for the most difficult joint I have ever made in my life.  

The epoxy actually acted as a lubricant to help me pound this joint together.

The finished beam.  You can't tell from this perspective, but the crown is 1/2" (1.25 cm) higher than the one directly aft.  This will allow water to flow away from the cabin deckhouse which starts right on this beam.

The inboard carlings are made up of three 4/4" laminations about 3" wide and are 30 feet long.  They will support the inboard part of the deck and the deck house.  They also determine the rake of the deckhouse sides so there is a camber of about 17.5 degrees cut on one side and the width of each layer are 1/4" shorter than the first.  The real strength will come from the 5/4" 6" wide strake attached to the carlings at the angle of the deckhouse sides.  That along with 3/4" plywood sides should be plenty rigid.

After laying them all out so I can use the natural curve of these pieces to good advantage, I've glued up the 1:12 scarf joints of the first layer of carling.  This one is for the port side.   Note at the very far end how the wood curves to the right.  There is an almost matching set for the starboard side.  It should help me get that fairly difficult bend at the forward end of the boat.
