TIME MACHINE

                                      

After installing the cabin top on the boat, I cut out the access hole and climbed inside my now, completely enclosed boat,  I sat to look around and plan/plot my next steps and had a wave of nostalgia wash over me, sitting there, in my cool boat cabin (I almost wanted to sleep out in the boat, that night) I was transported back in time, to being a young kid building structures (boat cabins among a few!) with my friends out of all the bed sheets in the house, all the adventures we had dreamed,,,, what a great time, and not a care in the world,,,, so, for a brief moment (if only we could capture that magic in a bottle) I was a kid again. I have to think that the younger me, would think it is very cool,,, that his older self is building a boat, a boat for adventures, with my family & friends. 

After such a trip back into time, it seems only fitting that the boat has now named herself,,,

 "TIME MACHINE", and my mind, much like my younger self ,while thinking of adventure, is working overtime, thinking of the possibilities for boat graphics, maybe a bit of Jules Verne or H.G Wells. an image of rivets,gears and alchemical symbols.

My high tech clamping system while the epoxy dries.

On a building note: I filleted and taped the interior, but decided against fairing anything to save weight...

Layers of unidirectional and plain weave carbon fiber to reinforce the bow, there will be allot of force trying to pry the front of the boat apart.

I am going to use an aluminum bowsprit and mast for the first season or so, while I educate myself enough, to feel comfortable building everything out of carbon fiber.

These foot bensons should be bomb proof.

The cabin floor has gone in. I did not go with dual bunks and decided I wanted a one piece, seamless cabin floor, I also decided to try out my new HVLP gun and pre prime the interior, which was a good thing, as I am not ready to paint my exterior with it, it would seem that I have a little learning to do before I tackle that. FYI: I am using Interlux Primekote and will use Interlux perfection as my finish cote. Read the MSDS sheets as this stuff is pretty nasty when sprayed.

I also fiberglassed the cockpit floor and used peel ply for the first time, take my advice, go with peel ply, it left a completely smooth beautiful surface, (I also figured I will leave it on for awhile, as it makes a really good drop cloth and will protect the surface). As usual I am behind on posting, and can say that now that the cabin top is done, it was worth the time I spent priming, and sanding is allot easier while the top is off.

 Let me add this, prep everything you can before bonding the top sides, tape 6mil plastic sheeting to the floor, wrapping up the sides, and you are ready to bond the deck and cabin top, with little care if you have any epoxy drips or runs.

I won't bore you with the small stuff, but after squaring and tabbing everything in place, it just becomes a ton of filleting and taping. I got advice from a friend that is building a 43' Dick Newick designed trimaran in Aspen, CO, and after that I started doing my fillets as follows. 1- mix and fillet several feet (I usually would try to mix up and fillet about 8-12 linear feet). 2- after filleting, start precutting your double bias tape (set aside in an order you can remember). 3- set up a piece of plastic sheathing on a flat work surface (I did mine on a 1x12 set on sawhorses). 4- Wait until fillets start to gel, and mix epoxy in small batches, wet out the precut pieces of tape on top of the plastic (I used a chip brush and squeegee), wet out then lay the tape to your fillet and squeegee in place (I found the side of my gloved finger worked well) also use your finger to gently push/slide the tape into the fillet, so that you get a good bond. doing this technique I felt I was able to work very efficiently, and created my best fillets.

Stringers: I pre marked where I wanted my stringers to sit, then cut plywood scraps to length and roughly 4" tall, I then used a technique counter top installers use, and held my stringer to my layout marks, then used a 3/4"X3/4" block/pencil to slide along my hull panel and transferring the exact hull shape to the stringer, I then cut to the mark with my skill saw, check that it fits right, now use it as a template to cut another, (if you laid your frames out correctly it should fit perfectly on the other side of the boat), repeat until all stringers are cut, then you get the fun of doing more fillets, by now it will be second nature (I put my iPod on shuffle, cranked it up, and just kept moving).

Stitching the hull and setting frames.

This was an exciting time in the build, and you get to see a boat take shape very fast. This is also where a good cradle will start to pay off. I found that my panels just laid in place, no bending, forcing, or very much tension on the zip ties was required. The green strap was used to just hold the sides roughly in place, there was no pressure on the strap, and the hooks kept the panel in place as I set frames and started to zip tie everything together. 

 Frame alignment/squaring the boat:  I had pre- marked the centerlines on all my frames, top and bottom and had snapped a chalk line down the center of the bottom panel when I had cut the frames/panels (I had also marked the centers of all my cradles) this helped in several ways 1- it allowed me lay the bottom panel, centered exactly on the cradle. 2- having the marks on the frames allowed me to set the marked frames to the chalkline on the bottom panel, and I was able to zip tie the frames in while also seeing their alignment down the centerline of the boat. 3- At this stage I had used auto jacks to level the cradle from my sloped garage floor and set the cradle level down the length and side to side, I then ran a string line down the length of the boat, at centerline, and was able to verify that my centerline marks at the top of the frames, lined up down the length of the boat. Everything lined up perfectly and after measuring diagonals from the stern, I had a little less then 1/16" variance in square,,,, TIME to start filleting…….

4- You will later be happy that you made those centerline marks as you construct your keel trunk, install your compression post, etc, as the marks have already been made, and by now you know that things will line up almost automatically. I hope that made sense and helps a little.

I plan to make the cradle available to any Colorado boat builders Spring/Summer of 2014 and would like to help anyone with an interest in getting their boat going, you can email me : i550sailor@aol.com

I cut all of the hull panels and almost all  of my frames with a skill saw, (only using my jigsaw to connect the dots on inside corners or the tight radiuses needed for cutouts).  A skill saw will cut most of the radiuses faster and more precise then a jig saw and will save you a ton of time. (buy a sacrificial piece of 3/4" plywood to stack on your saw horses, set the blade depth to 5/16" and cut away) also: look a little ahead of the blade, and you will follow the radius easily.

The next time saver was to do away with the messy paint to mark the tyveks, I got tired of waiting for paint to dry, so I stretched my tyveks across the 1/4" plywood, held in place with frog tape, and used a dark highlighter, to mark the outline of the tyveks, it created a nice sharply defined edge to cut to, with out the mess and wait time of paint.

Cradle

Hello and welcome to my blog page. I am building an i550 sailboat in Palmer Lake, Colorado, to race.

I was not going to start a blog, and just concentrate on my build, (not spending my time blogging about it).

But after thinking about it, I wanted to create a blog that is (hopefully) as helpful to other builders, as I have found the blogs, of the people who have already built their boats. Great job guys, and thanks for your help and taking the time to share.

Now on to some boat building. I am starting my boat by building the keel, rudder and compression post, along with the parts for my cradle first, my reasoning, is that my garage is going to get smaller, very soon.

I am much further along then this (I started the cradle in the beginning of November and should be glassing the bottom by the end of February, early March at the pace I am at), so it is time to update the blog, the nice thing about being behind on my blog is that I can use hindsight, to tell you what worked  for me and what didn't. On the things that worked great and I could not stress it enough, spend some time on building the cradle, it will pay off big dividends thru out the build, and the large wheels I bought at Harbor Freight work great for moving things around in my small garage.

I built my foils to plan (we will see how the rudder works later?) . I epoxied in (2) 1/4' stainless steel threaded rods thru the length of the keel, to attach the bulb. I then laid out my naca 12 profile and set my table saw to the depth and distance needed to cut to the profile and made (4) cuts per adjustment, 1 cut to the side of the keel, then flip end for end, rip again, then do the same steps for the rudder. I then adjusted the fence and blade depth and made the next (4) rips every 1/8". I used a block plane to connect the cuts, and in about six hours I had very fair foils ready to glass.
