Random Happenings in the Boat Yard

sunset in boat yard

Here we are at another spot where the projects we’re working on are just so long and drawn out that I’m waiting to be able to do a full post on them, or they’ve been so small that they barely feel worth mentioning.

So until I can compile a full post one one of the six projects we’re working on at moment, or since I do want to quick show you other little things that have been taking up our time, check out some of the random happenings around Daze Off.

 

  • We’re getting our water tanks ready for use.

No plastic water tanks on this boat.  Just like everything else, they’re aluminum.  And just like everything else aluminum, there’s bit’s of corrosion or pitting.  To make them use-able we first had to get them completely cleaned out.  Matt went to work in there with a combination of tools (but mostly just a grinder) to get them all polished and pretty.  It created such a huge dust cloud that after two minutes we realized that we needed to contain this mess as much as possible and threw a tarp over him while he worked with a flashlight to guide him.

When that was done it was time to protect them and make sure that our drinking water will stay safe and pure.  We’ve decided to go the route of epoxy.  The first coat has to be sanded in to give a slightly rough surface for the epoxy to bond to, but any coats after that can be painted right in and act as a barrier/protector.

I won’t lie.  While he was under the tarp sweating like a pig and getting blinded by all the dust around him, I was sitting out in the cockpit in the afternoon sun and sipping on the remainder of our Madeira wine straight from the bottle.  Don’t worry, I had my work cut out for me too.  I had the job of putting the final coat of epoxy on after Matt did the initial one.  I know, my life is so rough.  Feel very bad for me.

  • We’re still working on the fridge.

I know that a lot of you are really excited to see our next post on the final stages of us building our own refrigerator, but it’s been a lot of slow steps and that post is still coming. But don’t worry, I have not forgotten about those of you that are in the middle of the same project or just about to start it.

I’ll let you in on a little sneak peak of what the past few days of work on have looked like though. At the moment we’re focused on the lid, getting it to fit properly in it’s space, and then priming and painting everything.  I don’t want to spoil too much for my next ‘Stage 3’ post on it (but maybe it would let me skip having to write it then? No…) so I’ll give a quick gist of it. to make sure the lid and the fridge come together perfectly where there are no odd or wavy gaps allowing cold air to escape or causing strange rattles, we spent more time with our newest hobby of filler.

Mixing Q cells into expoxy, we spread the thick goop over the lip of the insulation we had already cut down.  Placing a plastic garbage bag over the lid itself so it does not permanently adhere to the epoxy, we set it in it’s place to form a mold with the filler.  Pressing down on the lid forces all the excess out which we scrape off and allow the rest to dry. Then sanding down the remainder once it has dried, we give it a smooth surface, see how well the lid fits into place at that point, and then do it again if we are still finding gaps.  Needing 24 hours to dry and sand each time, this is a very lengthy process.

Once it finally finished, 4 coats and days later, I was finally able to start painting!  Which at least lets my mind think we are near finishing this project even though that is in fact quite far from the truth.  But at least it’s something to keep me distracted and covers the ugly fiberglass coated insulation in a coat of pure white promise.

  • Our Gumby Suits came in the mail!

Yes,  I know, that is not the technical name.  They are full immersion survival suits, but after looking at the photos below you can see how they got their nickname. The purpose for them is that if we ever have to abandon ship in cold waters, these suits (if worn properly) will keep you insulated from the cold temperatures and keep you from getting hypothermia.  Although we’ve only purchased them for when we get close to Arctic waters, of which we’re still nearly two years from arriving at, it’s suggested these be worn any time you might find yourself prolonged in waters under 84 degrees as hypothermia can begin to set in then as well.  These suits let you survive in those waters indefinitely and give you a much better chance of surviving cold waters.

  • Work has begun in the head

Very slowly mind you as this is another case of a lot of epoxy work and filler and even more time of waiting for it to dry and work with it again. I have a feeling this project will take quite awhile and I will be doing a full post on it soon, so at the moment I’ll give you a quick preview of what we’ve done so far.

We started with the basic project of templating our sheets of Eurolite to fit against the hull and become our wall.  Or in this case, our shower.  It has since been layered in fiberglass to give it extra strength and to make sure that no water penetrates inside and rots the wood. Once all of those boards were in place we’ve needed to fill any cracks and gaps with epoxy and filler to make those water tight as well.  The real pain in the butt has been sanding down the colloidal silica.  It takes f-o-r-e-v-e-r. Once we get to the Q cells though, it should make it much easier to smooth down the excess filler.

Building our Refrigerator Box: Stage 2

Wednesday October 7, 2015

building refrigerator box

The last I had left you with stage one progress on our refrigeration box is that we’d measured and cut all the pieces of marine plywood, nailed them into place, and then filled the cracks with colloidal silica.  Doesn’t sound like too much work but did take us the better part of a few days.  Things still felt like they were flying along though since having large items constructed and taking up space in your galley is a constant reminder you’ve finished something.

The next step after the box itself was set up and water tight was to insulate it.  Instead of using the same spray foam we’ve been lining our hull with, or the same kind of stuff we spent hours chipping out of the old fridge, we used polyisocyanurate foam.  Which is a fancy way of saying that we bought the big sheets of foam insulation from Home Depot.  Overall we’re looking for a depth of 3″ of foam insulating our refrigerator.  This made it an easy choice to get the 3/4″ sheets instead of 1/2″, ensuring we’d only have to do 4 layers vs 6.  Less work for the same job = much better in my book.

Once the huge 4×8 sheets were dragged back to the boat we needed to cut them to size to fit in the box we’d just built.  After Matt had done a little research on the subject he’d found out that staggering the joints is the best way.  This means that instead of cutting 4 sheets of insulation the same exact size for the bottom and then measuring for one side, cutting 4 sheets the exact size, and moving to the next; you do one full layer around before starting the next.  So each layer for the bottom should be 3/4″ smaller on each side than the previous one.

Although it sounds like this should be one of the easiest steps in the process it was actually one of the hardest and most time consuming.  For each layer and each side in that layer we needed to take measurements (with two sides being odd shaped pentagons), mark and trace those measurements onto a sheet of the insulation, try and cut as straight of a line as possible with the knife on our Leatherman, and then squeeze it into it’s new spot in the box.  Usually with a few adjustments to be made.  Sometimes with the whole thing needing to be redone if we didn’t get the angle of the pentagon right.  It was a pain in the butt.

When we had 3″ of insulation all the way around we had to begin to shape the freezer as it’s own separate part of the box. Cutting two sheets to make a divider, we then built up the freezer space from the bottom and sides to make it smaller but with double the insulation.  In the end the space was bigger than we thought, bigger than we had in Serendipity, and something we should easily be able to fit a half gallon of ice cream in.

After that we ran foil tape around all the edges to seal off all the porous foam and making sure no water could get inside.  Another pain in the butt project but mostly just because it was so time consuming.  At one point we decided to save it for an after dinner activity where we worked on this tedious task while sipping Miller High Life and watching Archer on Matt’s tablet.

The next day was the fun step of putting all of the 24 pieces in to make sure they fit.  Which they did!  Bad part though was we forgot that we were supposed to stop 3″ from the top to make allowances for the lid.  Ooops!  Luckily the Dremel was on hand and ready for the project.

To permanently attach the sheets together we used two methods.  The very first layer which was being attached to the epoxied wood was stuck in place with a thick batch of colloidal silica.  We clamped the insulation to the wood, placed other long sheets of foam inside as a bracing system that would push the two together from the inside and left it overnight to dry.  The next day we finished adding the remaining layers with a gap filling insulation foam.  Once again it was left overnight to dry and the next day we filled all the remaining cracks with another thick layer of colloidal silica.

Whew.  I’m tired just reliving those steps.  But we’re not done yet for stage 2!

Since we couldn’t just paint the inside layer of sheet foam and call it good (although by this time I wish we could have) we needed a solid surface in there.  We decided to use fiberglass bathroom paneling. Turning it around we made sure the bubbly side was facing the insulation and the smooth side was out.  This was attached with colloidal silica and also had all the seams filled with a thick layer.  Another overnight of drying and then everything was ready to sand down and be given a coat of primer.

Seriously, I’m getting exhausted here reliving all these steps.  And to think we’re still near nowhere near being done!  Those of you who have written stating that you’re about to start your own project like this are lucky you told me or I probably would end the post here, just attached a few more photos and call it good.  Sheesh.  If we were smart we would have purchased multiple dorm fridges instead and added more solar to cover the charge.  I’m sure it would have been cheaper and much less heartache in the end.

Buuuut, we’re stubborn.  And so are you people that want to do this yourself.  Don’t say I didn’t warn you.

Ok, onto the lid.  This also required four layers of sheet insulation to equal the 3″ total we need for the top layer of insulation.  The *easiest* way to do this would have been just a simple rectangle to open and close over the areas, but it would not have made it very easy to open and shut in the end.  We needed three of the four sides to be at an angle. So, a little extra work now will save us a lot of hassle in the future.  We had been so proud of ourselves when we whipped together the lid for the fridge area in just a matter of a few hours, all measured, glued, and angles cut.  Only to find we cut the angle the opposite direction we were supposed to.

Another oops.  And other trip in to Home Depot to get an extra sheet of insulation so we could try again. One attempt later and we had it right.  From there it was set aside so Matt could begin multiple layers of fiberglass on it.

The very last step in this stage two of building our refrigerator box was to create the holes that will allow the cold air to flow from the freezer where the evaporator will sit and into the fridge.  In theory, once we have everything hooked up there will be a thermostat in the fridge area that reads the temperature.  Once it gets above a certain point a fan will kick on in the freezer and begin flowing cold air from the freezer to the fridge via the tube in the bottom.  Any warm air will circulate from the tube in the top of the fridge back into the freezer to be cooled down once again.

We also placed two shims inside the freezer for the evaporator to attach to which will then keep a 1/2″ distance between it and the wall of the freezer.

There you have all the work that went into stage 2.  Really, really should have bought those dorm fridges instead.  Stay tuned for stage 3 where we hopefully get this up and running!

Building our Refrigerator Box: Stage 1

Matt leveling floor

After searching for what seems like months now for the perfect refrigerator for Daze Off, we have come to one conclusion.  Although it would be soooo nice and sooo easy to buy a pre-made one that we just slide into place and plug in, there seems to be two definite problems with that.  1.  Our hull curves in so much that any of the larger sized fridges could not fit into the space we’re looking for, and if we put it against the flat surface in the center of the boat then the depth came out much further than one would like to have remaining foot space in their galley.  And 2.  The ones that would fit either of those areas were too small for our taste.

To go into a little further detail, we would have preferred a pre-fab fridge with drawers, but those all fell in the category of not fitting into the space well.  All the front open fridges we could find that did work with our hull shape and also the layout we have in mind for our galley usually fell in the 4 cu ft range.  We had 9 on Serendipity.  That would be cutting our cold food storage in half.  Not that we always filled Serendipity’s fridge to the top (unless we were headed out on passage or to the Bahamas), but it became a terrible game of ‘I need what’s sitting under 8 other layers’ the times we did.  Plus we could only imagine opening the door only to have all of the items inside topple out on us if there were any kind of motion on the ocean.

The only good solution left was to build our own.

A lot of planning went in to this (on Matt’s part, god I love him for figuring all of this out), and once we had our approximate measurements of the outside of the box it was time to head to the hardware store to buy a sheet of 1/2″ exterior plywood to begin the project.

Our first step was making cleats to add on to a few of the aluminum frames that came out on angles from the hull, allowing us to be able to have a level board sit down when we were finished.  Once the cleats were installed we were ready to cut the bottom board but also had to take into account the frame, slicing a small section out of the plywood’s edge so we could fit the board around it.

The back wall of the box needed to be built in two pieces to allow for the curve of the hull.  We do want to maximize the usable space in this fridge as much as possible which is why we decided not to build it straight up and leave a large gap between the box and the hull. Making sure that everything was level and that we’d be ending at 90° angles, we measured and cut the back two pieces, also having to make an allowance for the frame on the bottom of the two.

I had thought the sides would be much easier to cut but forgot to factor in that they needed to be pentagons to, once again, work with the curve of the hull.  You should have seen the drawings I had in my notebook as Matt was giving me measurements to write down. Top – 23″; front side 19″, top back side – 8″, remaining – 12″.  Eventually I had to make drawings to keep it all straight so we could remember what line connected to what when it was time to mark the lines on our plywood.

The front was by far the easiest, and once we loosely assembled it together it was nice to step back and say “Wow, look at all we were able to complete in one day”.  Except, we were still so far from finishing. I had also forgotten that we needed to cover the metal frame that was running through our refrigerator box. Using sheets of Eurolite for this we cut two pieces that covered the top and side and also cut some sheet foam to slide under that area so that once it was closed off it wouldn’t be sucking cold air into a useless area.

That was enough to fill one whole day, but in the end it still felt like we accomplished a lot more than we have on a normal day lately.  Day two was prepping the wood for final installation and also do all the final prep to that space before the boards were permanently placed, such as insulating and running conduit.

While I was sent outside to ‘epoxy the s#*t’ out of the boards, as Matt put it, he was inside working on more spray foam insulation. It turns out the previous owners of our boat once again had it all wrong.  Where you’re supposed to have insulation from the overhead leading to the waterline, they instead had bare metal all the way down to the waterline and then decided to insulate from there to the bilge.  Oh that’s right.  They needed a place to hide their drugs.

So Matt went through and properly insulated the rest of the hull and made a huge mess in the process when he tried to add a little extra to the existing insulation to the overhead.  But it was also kind of nice knowing that I’m not the only one who makes big mistakes on this project of a boat.  So yeah, a lot of my free time is now going to be spent scraping off bubbles of foam from the walls, cabinets, floors, and even the plexi hatch.

A few days later once the plywood had two coats of epoxy we were ready to screw all the boards in place and fill any gaps.  Working with my new best friend, epoxy, we added some colliodal silica to make a nice thick paste which we then ran along all the cracks and made sure they were thoroughly filled.  This should make sure the frame of the box will be completely water tight.  A very good thing when condensation is a high probability.

So there you have it for stage one of building our own refrigerator box.  Stay tuned for the next step where we get to insulate!
