Deck the Hull with more epoxy, fa la la la la, la la la la (sorry, I couldn’t help it!).
At this point, both the inside of the hull and the inside of the deck are fiberglassed, and it’s time to put them together. The outside seam is easy; the inside seam is another story.
Day 48: 7/24/12 2.5 hours
I flipped the deck back onto the hull and taped it down again. To make sure the bow butt seams stayed aligned, I rewired the holes to keep the deck in place. I used a razor knife for adjustments, especially near each end. Taping down the deck is easier with an extra hand, so Mark volunteered to help again. One of us would hold the deck in place, while the other taped. Next I added a strip of blue painter’s tape close to the seam to catch any drips. The last step for the night was to squeeze a bead of epoxy in the seam. I finally broke out a new syringe – it’s amazing how much easier it is to work with a new one. The tip is still small because we haven’t cut it yet to allow for the epoxy thickened with wood flour. The new rubber on the plunger makes it much easier to control than ones that have been through many epoxy and acetone treatments.
Day 49: 7/25/12 1.25 hours
Now that the boat is glued together, I removed the fiberglass tape. I had to fill the gaps left by the tape with epoxy. I also added a bead of epoxy thickened with wood flour to the entire seam.
Day 50: 7/26/12 2.5 hours
Tonight I started on the inside seam that holds the deck to the hull. Keep in mind that now there is only the cockpit hole to work with, and I need to fill the entire inside seam of a 17-foot boat. I wish I was taller! In any case, the instructions have you make an extender for the syringe. Basically you tape the syringe to the end of a 6-1/2′ stick. Then you screw two small eye screws to the stick, one 4″ from the syringe and the second one at the other end. You insert a 1/4″ wooden dowel through the 3/8″-diameter eye screws until it butts up against the syringe. Since Dan has made at least ten boats by now, I figured he already had this contraption – which he did.
Dan showed me how to prop the boat up with a stick so that the seam was horizontal to the floor and the epoxy wouldn’t drip. Once I filled the syringe with thickened epoxy, I had to wedge myself into the cockpit as far as possible to try to reach the ends. I also had to fit both arms in front of me and control this long stick with a syringe in the end. I probably picked the hottest day of the summer to work on the inside seam. In addition to the heat, I used a small lamp to see inside the boat which took the temperature up 20 more degrees! This was a horrible process – and I couldn’t get to the end of the boat with it. Dan said that, in the past, he never was able to reach the ends of the boat, but that was okay.
After filling the seams, I cut a piece of fiberglass tape and layed it on the seam as far up as I could reach. Then I painted over it with clear epoxy using a small disposable glue brush. I also added another bead of thickened epoxy to the outside seam that was now on top of the tipped boat. I was happy to leave the boathouse that night, and Dan was probably happy to have silence instead of listening to my complaints!
Day 51: 7/27/12 .75 hours
The next day at work, I read an email from Pygmy Boats that advertised their boat building class. The class is only six days long on-site and you get a lot of the boat done. You don’t leave with a finished boat, but you get pretty far. They have found several ways to speed up the build time. I thought for sure they’d have a better way for filling the inside seams so I called them. Although they have improved some processes – such as taping more and drilling and wiring less, they still used the stick contraption to fill the inside seams. Pygmy also suggested that I try harder to reach the ends. It was time to make a longer stick.
As usual, I trotted down to our Product Development department with my request. I am now known as the one who comes up with the most outrageous requests for tools. Although we didn’t have any long dowel rods around, George handed me 6′ metal shelving standards. I dug around the office and found three large binder clips. I taped the clips onto one standard and slid the other standard through a space in the clip. This enabled one standard to slide to push the plunger on the syringe. I thought it might work!
I showed up at the lockmaster’s house that night with my new contraption, and Dan rolled his eyes as expected. I checked out the stick I used the night before and realized it was only 4′ long. Turns out that Dan had used a 4′ stick instead of a 6 1/2′, stick and the dowel rod was only 3′. Since Dan has built his last boat, Pygmy updated their instructions to a 6′ stick. Dan read the instructions for the new boat he was using and realized it said use a 6′ stick and get to the ends. Anyway, I taped the syringe onto the end of my new metal syringe extender. It worked SO MUCH better! In fact, the metal shelving standards were very light and had a nice bend so that the syringe hit the seam at a nice angle.
Day 52: 7/30/12 2 hours
Today I showed up ready to hit the other inside seam with my new invention. I handled this one like a pro! I tipped the boat the other way and easily filled the inside seam with a bead of epoxy all the way to the end. Then I laid out the glass tape and painted it down as far as I could reach over top of the recently epoxied seam. Finally I hit the top seam with the second layer of thickened epoxy.
Day 53: 7/31/12 3.25 hours
Now that the deck was securely attached to the hull, I could scrape off the epoxy on the outside seam and use the required force without harming anything. Since I know one of my weaknesses is hand scraping these seams, I recruited my husband Mark to help again. I showed up first and started to take the edge off the seam with the yellow sure form shaver that has been one of our primary tools. Then I used the paisley shaped cabinet scraper to remove the rest.
I was busy working my way down the first seam when Mark arrived in the shop. I showed him the tools and the steps, and he went to work. Having him help that night was a fantastic idea! He finished all four seams by the time I finished one! We finished the whole job in one night! Woo hoo!!
Gary and Dan were working on the inside of Dan’s deck while we were scraping away.
Day 54: 8/3/12 2.5 hours
I made it back to the shop on Friday to sand the deck and prepare it for fiberglassing! With Dan’s help, we moved the boat outside and I broke out the Festool Rotex Sander and Dust Extractor. I used 220-grit sandpaper.
When I finished sanding, I vacuumed off the dust, brought the boat inside, coated it with epoxy and smoothed out the bubbles with a foam brush. Wow – does it look great!
