A double layered bottom

November 21 2016: Got ahold of my epoxy and hardener; the three to one stuff recommended by the US Composites tech. Also got the shop somewhat ready for the colder weather by plugging up some holes in the tin with duct tape and readying the stove and chimney. I further brought in two space heaters as well as some clamp on lamps that I can hang over the hull. All of this should help keep the shop in the daytime around 55 degrees which is essential for the epoxy to set up.

Yesterday evening my wife after she returned from her shopping trip and myself went out and began emplacing the next layer of sheeting on the hull. A little bit of give and take was required but it was all emplaced by 8:45 in the evening. The shop at that time was relatively warm; I’d say easily into the sixties. Pretty remarkable since it did not get much above forty the whole day. Yet that still meant I had to keep the temperature in the shop up for at least another two hours; so at 11:20 I called it a night.

I figure the next big task will be fairing the edges around the sides and preparing to sheet the sides of the hull. My older girls will be down here around that time so hopefully they will want to help lol!dsc01718 dsc01719 dsc01720

Good Information

Hey there shipmates. Well I contacted US Composites today concerning an order that I had placed which was the wrong order. Turns out I have been using the wrong type of Epoxy and resin. The technician stated that the 1 to 1 epoxy system  (which the 1 to 1 system can only be used with the thick epoxy resin) was the wrong system to be using on the boat. Turns out the thick epoxy resin is to stiff and rigid to be ideal in boat construction. He recommended the thinner stuff with a three to one ratio as that seems to be the best choice for boat builders. Using Mark’s plans and tips for the boat, he called for a one to one epoxy and hardener ration; thus when I saw that US composites used the one to one only in their thick stuff, I naturally chose that. Anyways the thin epoxy system I have is what I will be using from here out and the tech said not to worry as using the thick stuff thus far would not be a deal breaker.

On the subject of temperature, the tech enlightened me that the three to one system requires at least 55 degrees to set up and cure for at least the first two hours. Good to know as it should stay in the sixties and fifties around here for a bit. Also he suggested that in the colder months, heat lamps could be used to ensure that the epoxied surface will be at least at fifty five degrees. So I have an infrared thermometer and several heat sources I can em-place around the boat to ensure this happens.

So bit of an enlightening day and glad I called and got the info.

Issues with Temperature!

November 13 2016: Yes I know this is becoming a bit of a thing with me posting for a few days’ of work and taking forever to catch everyone up. What can I say things are busy and when I am on the laptop I am doing school work! If anyone knows how much it sucks being an adult and responsible it is I.

I have tweaked the port side of the bot with more epoxy and screws and began fairing her down. The Starboard side of the bow was sheeted again in much the same fashion as the port side. I happen to think it looks a little better than the other side but maybe that is because I found a few tricks to help.

Since it is getting later in the year and as one might expect; it has cooled down a good bit. With temperatures at night getting into the thirties. I think this is starting to wreak havoc on my epoxy as I have had the bow planking strips begin to delaminate when I pull the screws. A judicious amount of epoxy and more screwing has seen the remedy of this problem. It is somewhat curious because before I never had a problem with things delaminating like they seem to now. I can only assume it is because that it is due to the cooler temperatures.

If it is because of the temperatures, I am going to have to figure something out. If the epoxy will simply not set up during the cold I will need to either wait for warmer weather. Or I will need to find a new adhesive I can use that will do the job just as well be darned the temperature. Perhaps an email to US Composites is in order!dsc01715 dsc01717 dsc01714

Second Layer of Hull Sheeting and Panic!

November 8 and 9 2016: Well on election day I went ahead and began emplacing the second layer of plywood on what will be the port side of the bow. That actually turned out to be somewhat harrier than the first layer. A lot of creaking and groaning happened and a few of the strips actually began to split! I figured that could be dealt with by adding a healing layer of epoxy. I used a lot more screws as well because the strips had a hard time wanting to hold shape. Further I figured out that the splitting actually lessened when I walked the curve up with the screws. Installing them every few intervals on differing sides of the strip. I also used copious amounts of thick epoxy to ensure a good amount of stickum was spread for safety sake.

The next day after coming home from school I discovered that both layers of sheeting I had applied on the port bow actually sheared away from the chine log. Needless to say I was almost in full panic mode. Yet I assessed the situation carefully and decided I could use one of my bar clamps to move both layers of sheeting back to the chine. I did this in intervals and applied 3 inch deck screws for extra grab and hold. That seemed to work fine but I also decided upon actually spreading a large amount of epoxy along the inside and outside edges for extra stick. I also figured that this may happen to the starboard side when I go to sheet the second layer over there. Thus I applied the same technique on that chine to reinforce it as well. So far it appears to seem that it will set up rather well (or so I hope).

After that calamity was averted, I went ahead and trimmed the excess from the second layer of strips. Looks pretty sturdy!dsc01714 dsc01712 dsc01711

Transom and first layer of hull Sealed!

November 7 2016: Sorry for the delay in getting back and updating everyone. It has been a very busy few weeks with a short turnaround for drill that was exceptionally long as well as school being a bear. However I have made some pretty good progress on the boat.

As promised more Epoxy and cabosil did arrive which was used to fill in gaps between the pieces of plywood and finish the transom area to get her closed in. I had to extend the keel as well as cut smaller pieces of pine to create fill in between the four ply transom and the bottom of the hull. They were cut and epoxied into place relatively easily and secured further with screws. Next came the encapsulation of the stern with the plywood for the bottom of the hull to frame J and another enclosing layer of plywood over the four ply piece. In essence the actual transom that the motor will mount on ended up being five pieces of plywood. Yet all this was epoxied and screwed into place to seal up the stern.

Looks pretty good all things considered and I think we are ready to emplace the second layer of plywood sheeting to the underside of the hull.

Time to Tidy!

30 October 2016: Since tomorrow is my refill day for Epoxy and I am currently all out; figured it would be a good time to tidy the shop. It frankly had gotten kind of out of hand. So after my doing some homework, it was off to the shop I go like a good little apprentice! I spent probably a good four hours just cleaning and reorganizing. No doubt when it comes to shop cleanliness and organization I am my father’s son (sorry Dad!).

When that was done however I began thinking about how to button up this transom when the epoxy arrives. Pretty sure the idea I came up with will work fine, but I will percolate on it until the stickum gets here.

Gocycle

We’ve had some various electric bikes and folding bikes on here before… here’s another one that looks slick:

This is will be the fourth generation of their product, so it’s probably not a total shot in the dark, but I can’t vouch for them myself. Certainly looks like it packs up pretty nice for on-board stowage.

Transom attention

October 29 2016: Today began with determining that I may have indeed made yet another mistake; although once again nothing that cannot be rectified or one that is irreparable.

The plans from what I read after sheeting the majority of the hull call for the transom area and lockers to be sheeted and emplaced first. That means the four half inch ply transom meant for the motor and the walls for the inboard side of the split transom emplaced before sheeting the hull.

Since the interior transom called for an angle of 12 degrees, I figured it would be a good time to have my wife come out and help. Being she is the math whiz behind this consortium of effort. She readily verified the drawing and we soon had the exact location and emplacement of the transom. We also had the exact size negotiated; since I simply created a four ply transom from the hole between the two split pieces. Evidentially that is not necessary (its way to large) and the four half inch plywood piece for the motor is actually somewhat smaller than the hole.

I cut the big ole transom down to size with my sawzall and planed the rest to the correct size. The locker sides were cut for the most part without issue and dry fitted into place. Once we had everything ready to go and fitted; epoxy was mixed. We attached the side pieces of the lockers first with screws and epoxy before fitting the beasty four ply middle section. The honking transom piece took some persuasion with a mallet and muscle to fit appropriately. Savannah and I screwed and epoxied the crap out of it until we were satisfied it was emplaced securely.

While there are still some gaps to contend with, I have every confidence that they will be dealt with accordingly. No doubt using copious amounts of both timber and epoxy!dsc01691 dsc01692 dsc01693 dsc01694 dsc01695 dsc01696

Hull Skin Part 1

dsc01690

Today started with the usual hot cup of coffee and opening of the shop; followed by what I planned to do today on the boat. Seeing what I got done the days prior, I figured it may be prudent to ask my lovely wife for help. She is a much better and skilled climber than I (after all she has had to do it all her life! lol) and I figured she could manage the on top of the hull part of sheeting the boat.

I didn’t really need to beg as perhaps one might imagine, she quickly got on her shoes and decided to assist me.

We soon had a tentative plan worked out on how best to tackle the jobs that day. Firstly we went ahead and trimmed all the overhanging plywood so as to make the space a little more user friendly. After that, Savannah mounted the hull and I began to hand her sheets of plywood to lay out at the correct angles for attachment. She would hold them in place while I secured the outer part of the plywood to the chine with screws and epoxy. That went rather well; although some issues arose pertaining to gaps and the odd pieces to fill them. Yet all in all, the sheeting of the hull to approximately frame B went rather well.

Afterwards we decided a divide and conquer approach was best. She would trim the excess plywood from the keel and the outboard sides. While I planked the forward part of the hull with two and a half inch strips of plywood. These narrow strips or planks made it much easier to create the “bend” on the forward part of the hull.

At present I have enough epoxy left to make one more batch and that is it. More epoxy is on the way and according to UPS should arrive Monday. I plan on using epoxy to fill in all the seams on this part of the hull prior to emplacing the second layer of sheeting. My cabosil reserve is also becoming a tad low, however not in the danger zone yet. That cabosil filler is absolutely awesome and seems to really last! I plan on placing a Cabosil order today; but this will only be my second refill order.
