January 3,

I measured how much epoxy I have left and have decided that there is not enough to ensure full saturation of the cloth for even one side.  I'll have to save up my pennies and purchase another drum of epoxy.  I don't expect to have that kind of money for some time so in the mean time I'm choosing projects that can be accomplished with little or no money.  One big one is the construction of the skeg keel appendage.  I'm making the skeg out of laminations of 3/4" Meranti plywood ripped to 4 inch widths.  This will produce a strong and stable appendage.  I've been cleaning out the boat shop so naturally I have a large collection of scrap plywood from the bulkheads and keel stump construction.  I used every scrap I had and was able to collect enough for the entire skeg.  Keep your scrap, you never know what it might be useful for.  Now comes the task of lamination.  I've dry laid the entire skeg and bar clammed it together.  I lost 3 inches in the clamping process.  This means, I'll have to lay up the laminations in sections compensating for the lost length due to clamping as I go.  I figured as much and have a few extra pieces of lamination for that purpose.

I've detailed this process in the February section.

Merry Christmas, Happy Hanukkah, Happy whatever you're into.  Solstice was a few days ago and we're in a new year.  I'm hoping for some warm weather next week to lay up half the hull with fiberglass.  Yes we are expecting warm weather almost in the 70's.  The warmest is over Christmas where my wife and I are obliged to spend this wonderful weather indoors eating and drinking.  I'd rather be working on the boat or enjoying this wonderful weather out doors.  Well, that is how it goes.  I have received the fiberglass necessary to encapsulate the hull.  Well, I think I have enough, I'm starting to think that I did not buy enough but I have a contingency plan.  I'm splitting the formidable job into two parts anyhow; the port and the starboard side.  I'll access the need to purchase additional glass once I lay up the starboard side and buy what I need.  It should not be too painful.

I spent the entire day and a bit of yesterday cleaning the shop and getting the dust off the hull.  I also was concerned with dispensing a 80 pound roll of fiberglass.  I was counting of using the angle of the bow to my advantage, so I did not want to cut 50 foot lengths and lay them up.  I wanted to be judicious as possible.  Remember, I'm on a tight budget.  To that end, I built a vertical dispenser using some scrap lumber, a lazy Susan, and some 3/4" black pipe I had laying around.  I really did not want to roll the fiberglass out onto a table or the floor.  I want to keep the glass as clean as possible without any possibility of snagging or warping the weave.

So this is my dispenser.  I used a 25 X 25 inch base made out of fiberboard.  I added 2 X 4's for feet and to give  some depth to insert the pipe.  I had a lazy Susan lying round with 1/4" plate aluminum riveted to one side.  It was from an old project that was abandoned.  I drilled a hole in the aluminum so the pipe would fit down the middle.  I drill a 3 inch deep hole in the center of the fiberboard so that it went almost through the 2 X 4's to receive the pipe.  I cut another square piece of fiber board (13 X 13 inches) with a hole in the center so that it fit on top of the lazy Susan.  Now the 13 inch board freely swivels.

This was much easier than I anticipated.  I laid the roll of fiberglass on its side.  Slid the 3/4 inch pipe through the center.  Added the 13 X 13 inch plate, lazy Susan, and then the 25 inch base.  Then I used the black pipe to leverage the whole contraption vertical.  It was much more stable than I anticipated and the fiberglass should pull right off without having to roll the mat out on the floor.  You can see the end of the Starboard bow to the right of the roll.  We are almost ready to tack the glass in place.

I've also worked out how I'm going to hold the glass in place while I roll the epoxy resin on.  I'm planning on hanging the cloth in place using brads nailed about a quarter of an inch into the hull and let the cloth drape naturally.  I can clip the heads off so that only about a quarter of an inch remains to hold the cloth and apply the second layer of cloth again hanging it on brads.  The clipped brads will interfere minimally and once the second layer is draped I'll press it onto the clipped brads.  All the brad heads will then be clipped short.  The epoxy can then be rolled on.  Once there is enough epoxy to hold the cloth in place, the brads can be removed.

Finishing up the keel stump.  I've built up the keel with plywood and planed it perfectly flat to receive a final plywood cap.  I've altered the original pattern so it now duplicates that last plywood cap.  I will then be able to continue building the keel on the workbench and bolt it on later using the nice flat mating surfaces.

This is the built up portion of the keel with the plywood capper off to the left.  Notice the nice horizontal stripes that are  the different plywood layers.  I used these stripes as a guide to maintain a smooth even cut when I leveled the stump.  The bottom of the image shows the aft end of the keel which slopes forward 3 degrees.

This is the forward part of the keel.  I also worked on the transition from the keel to the bow.  I think it needs  more faring but I don't want to cut too deep.

Looking aft.  Each of those colors is a different layer of the plywood.    

This is the keel stump with the plywood cap temporarily in place with two metal pins fore and aft.  The  pins locate the cap in the correct position and will be removed after it is epoxied into place.  They are great for quickly placing the part in the correct position after the epoxy has been applied.  Epoxy makes things very slippery and the part to be fastened in place will slid around making a mess.   I used drywall screws to fasten the cap in place after the epoxy was applied.  This gave nice even clamping pressure.  The screws were removed when the epoxy was partially cured.  If you allow the epoxy to fully cure, it will grab the screws and you risk breaking them off when trying to get them out.  There are no permanent screws in the entire stump.  I do not want anything to interfere with the drilling of the keel bolts.  A screw could redirect the long drill bit or dull it.   The 3/4" stainless keel bolts will be sufficient to add mechanical strength to the keel.

June 2016,

We are almost ready to start fiberglassing the hull.  Only a few more things I'l like to get done first.  One of those is building the ballast keel stump.  The is just leveling the bottom of the hull where the keel will bolt.  I started by building a pattern of the external keel as it would be up against the hull.  I laid this pattern in place on the hull and marked its outline on the hull.  After removing the pattern I made sure that the hull within the outline athwartship  was level.  This required filling with more filler strake or planning existing hull off.  The result is a level surface (athwartship) that I can start building up the keel stump.  The next step is to take the keel pattern and transfer it to 3/4" marine plywood.  This takes two pieces 8 feet long and we will call this a keel slice.  This first layer or keel slice is fitted into place and bonded with epoxy and stainless staples.  I perform a similar transfer and make another keel slice out of 3/4" marine plywood but this time I have shortened the forward piece around two inches.  This is because the forward part of the keel sweeps back at a 45 degree angle and the aft part of the keel sweeps forward 3 degrees.  I purchased the straightest 2X6X14 foot long piece of pine I could find and mount it edge up to the new keel slice making a ~16 foot long section that is rigid.  Using a 6 foot level I place this keel slice in place and temporarily fasten it so that it is perfectly level.  I actually left out a few steps; One is attaching the 14 foot 2X6 to the pattern first and setting it into place so that I could measure how much shorter the keel slice would be which is a function of the separation of the installed keel slice and the perfectly level pattern.

Leveling the second keel slice using the 2X6 and a 6 foot level.

You can see the first keel slice which conforms to the hull along its length and the second above that is perfectly level.  The space between the two slices of keel will be filled with plywood.

 The gaps between the two keel slices will be filled in with plywood.  I am planning to use 3/4" plywood to fill as needed with square cuts and then the triangles that remain will be over filled with 1/4" plywood.  This way, when I sand the edges smooth, I will only be sanding the 1/4" plywood and will have a reference every 1/4" of vertical measure.  It's also a good way to use up that left over scrap 1/4" plywood from the hull construction without using a lot of the expensive 3/4" plywood and sanding most of it into dust.  The top slice will then be permanently bonded to the keel finishing up the keel stump.

Later, when the boat is righted and the keel is ready to install, I'll bore the bolt holes through the keel stump first, align the keel and bore the holes through.  I will then cut out the ballast section and send it to the foundry for casting and pouring.  If I had a good lead supply, I would attempt this myself but lead is hard to come by these days.  All the tire companies seem to be contracted to someone in some manner and won't deal with me which leaves me buying lead on the open market and that is just too expensive.  So, I'll go with a cast iron keel for now.  The material is free but the casting is expensive.

Here, I have added the 3/4" plywood fill for the keel stump.  Notice that I still have the wedges to fill in front of the plywood.  I plan to over fill these wedges with 1/4" plywood so when I plane the excess of the 1/4" plywood down I'll still have the corners of the 3/4" as a running reference of how much material I need to remove.  More steps this way but less work and more accurate results (I hope).

This weekend I have finished the lamination of the hull; all four layers.  I started this process on July 2, 2013.  I still need to do a little trimming on the port side and some sanding at the stern and bow but it's all installed.  That was 128 sheets of 1/4" plywood cut to 10" strips (640 strips).  For most of the hull, two strips were scarfed together (320 scarf joints) to make 320 16 foot long strips which were temporarily fastened to the hull.  They were marked and measured, cut and planed, resinstalled and checked (repeat as necessary), and finally permanently bonded to the hull with epoxy and stainless steel narrow crown staples.  Then the seams were sanded smooth.

This is where I was on May 21 working toward the stern.

This is the keel.  I'm preparing to trim the port side at the keel.

My new 36" X 4" long board for fairing the hull.  I built this from the 1/4" hull plywood which is fairly stiff.  I added 24 gage stainless steel to the bottom and wrapped it with 36 grit sandpaper.  Remember all those hand saws I went through when making the notches well that is one of the handles from one cut at a comfortable angle.  The front handle is just some rounded off oak.

Keel all trimmed up and ready for the filler strake.

All the plywood is installed toward the transom.

All the plywood is installed toward the bow.

All the plywood is installed toward the stern.  A bit of trimming and sanding is still needed.

May 30.

Finally, I got a camera with a panoramic setting so I can get the whole boat in one picture.  This is it.  The planking is completely finished with all the sanding trimming and fairing.  Well, I'll probably tweak things while I get the appendage keel stump built.  That is the last thing I'm building before glassing the whole thing.  I am also quite busy at cleaning the shop.  No spare sawdust hanging around during the glassing process. 

March - April 2016

March 8

Last weekend was a remarkable time for working on the boat.  The weather was perfect.  Except for a few last items the starboard planking is complete.  I still have to trim the edges, sand/fair the hull and add the last few strips to the stern all which needed to wait until I made some custom sized strips necessary to compete the stern.  Those custom strips are compete and I have the starter strip for the port side installed.  While finishing up the last layer on the last side, I'm starting to think carefully about the next steps.

•   Overall fairing of the hull (minimal because the hull is in remarkable shape).
•   Installing bronze screws through the planking into the keel and transom.
•   Installing the filler strake beneath the keel and sanding the planking flush to the filler strake.
•   Leveling up the keel with dead wood to create a platform (keel stump) for the installation of the fin keel and skeg.
•  Fiberglassing the hull with a layer of mat and woven glass.
• Building up a few layers of barrier.  This will be the West System epoxy with a special barrier coat additive.  
• Apply a few coats of epoxy paint.  

All of these should be straight forward although leveling up the keel of the fin keel attachment has take some thought.

March 10

I ordered West 206 slow resin hardner for the warmer months as well as enough thickener to finish up the hull.  I've also purchased another 5000 5/8" staples which should get me through the last bit of planking.  I'm ready for Spring, are you?

March 11

Sanding of the starboard side is almost complete.  I've started marking a few small low areas about the size of my hand that need filling.  This will be the majority of the fairing that will be performed.  I know I have a few larger areas in the bow area where the hull changes rapidly but I do not expect the need for excessive fairing.

March 17

Sanding, sanding, and more sanding.  I woke up this morning around 5:00 am and worked on the boat for a few hours before my real job.  Starboard side has been sanded.  A good supply of strips for the final layer of the port side have been made in preparation for a nice work weekend.  I had already switched to the West System 206 slow hardener for the warm days that we have had.  This weekend is going to be much cooler and I'll have to switch back to the 205 fast hardener.  All of the supplies I ordered on March 10 have arrived and I'm looking forward to making a lot of progress.

The port side final layer proceeding nicely. I still have a bit of sanding to do.

The right side is complete.  The left side is moving along.  I start as far astern as possible so that the strips lay on top of the last one installed.  This is much easier than pushing them underneath the last one.  I'll have to do that a little in the back but  it really saves me time to start as far aft as possible.  Of course you have to judge the angle the strips lay correctly or you will run out of length as you get to the fatter sections which happened a little on the left side.  I add a little filler piece and gradually change the angle until the strips are again long enough.  No harm in that.

Another view of the bottom of the boat looking forward this time.  You can see the filler triangles in this view.  Once they are sanded they will disappear.   

April  8,

I breathed a sigh of relief yesterday when I got that strip in that laid flat and nice.  The middle of the boat hull has a tight radius just below the water line that makes it extremely difficult to fit the strips properly.  It requires screwing the unshaped piece, or blank, into place, marking, cutting and rescrewing the strip in place to check the fit.  More often than not this process must be repeated more than once mostly because the hull shape changes even in those ~2 inches (50 mm) that the blank is set off from its final placement. Very time consuming.  Now that  I am past that portion of the hull, the blank can be laid into place with only the clamps and marked, cut and checked.  This usually takes one iteration and goes much more smoothly.  I am done with the tight radius hull section and on to the easier smooth sections.

April 11,

Unfortunately I've taken on a temporary second job on the weekends to make a bit extra cash.  I still managed to put in a half day on Sunday and got 53 square feet (5 square meters) of hull installed.  Not a bad half day.

April 22,

I bit more of the hull installed and I've prepped some work for this weekend.  I'm mostly working on Sundays now that I have an extra job on Saturday.  Hopefully this extra job will only last a few more weeks.

Getting to the shorter and easier pieces on the bow.  This should go quickly.  I still have a good section in the stern to finish so no celebration yet.

A top view of the bow.  I still need to clean up the starboard side at the bow near the bottom of the hull.  I'll take care of that on Sunday.  Of course there is still quite a bit of sanding to do.

February 2, 2016.

We had a few warm days that allowed a bit of boat building.  The heated epoxy box made it a breeze.  I've made quite a bit of progress on that last layer on the starboard side.

I have quite a bit of the last layer of the starboard side complete.  I've certainly gotten past the hard part.

You can see were I mark the panels at the keel where I will need to cut them,

Looking toward the stern.

Feb 17.  It's been too cold to work with epoxy for the last two weeks.  I've prepped some strips and look forward to a good day of boat building this weekend.  Temperatures should be around 65F (18C), a nice day for boat building.
