Re: New boat project CCSF25.5 - build thread

[Admin - Shine]

Sprayed the last coat of EMC primer last week, now in the process of lifting her off the jig.  Most of the jig is removed from the underside (molds were in two pieces so that was easy).  Jacking it up off the platform, then removing the platform.  Will put it on casters so i can roll it into the paint bay for painting the bottom.  Then make a jig and flip

platform removed, most of the jig removed. Sanding the final primer on the bottom and prepping for paint...

Nice!!

[Admin - Shine]

Put a coat of paint on the bottom this weekend.  Will be putting on another coat to build some more thickness.  Gloss is outrageous.  Paint is the EMC Quantum that I use/sell.  Color is snow white.

I have been following your build and your boat looks fantastic. I started building a flats skiff and have been deciding whether to go graphite/epoxy or 2 part paint for the hull bottom. After seeing how yours turned out I may end up spraying EMC on the bottom/sides.

Welcome!

Its really pretty easy, just have some primed sample panels to dial in your gun before moving to the boat. I like the graphite, but it does not give nearly the same level of finish.

feel free to post any questions you have about finishing or the the build, always interested in seeing other projects

[Admin - Shine]

roll over cradle is finished, now just have to roll it outside and get a piece of equipment to pick and roll.

[Carolina flare]

Nice job on the cradle. Can't wait to see that boat right side up. I'm real interested in the build out from this point forward, should progress nicely with out all the frame work of a stich ang glue design.

it will certainly go much faster.  Most of the rest of the build is flat/straight parts

[Admin - Shine]

A few pictures of the flip. Have a short video on another phone. The google gallery for this build has all the pictures.

Rolled it over almost all the way. removed casters from top and relocated them to the bottom before setting it all the way down. Spun the hull around and rolled it back in the shop (bow first)

Looking good Joel, keep up the hard work.

[maxtork]

Wow that looks great! I have been watching this build for awhile now hoping that it would motivate me to finish up my boat project. Well it did and I am back underway working on it again. I hadn't seen any progress pictures in awhile and I was going to bribe you with a purchase of a few gallons of epoxy and some glass to finish mine if you would post some more pics!

Great job and don't worry I will still be ordering stuff to finish mine up. I need to get it out of the garage so I can start building one of these!

Thanks for the kind words Max. Hasn't been a lot to show as of late, sanding/painting can take days, but the boat doesn't really look much different. Work is going into high gear starting now. Next step is to block up the hull, remove the rest of the molds and interior cradle framing, then start glossing the inside of the hull.

[Carolina flare]

That's outstanding Joel!
Do you have do do much filling between the planks with thickened epoxy before glassing?
Well you be able to fill and glass wet on wet?

I filled most of the strip gaps from the inside before I glassed. Up in the bow, there were too many molds to be able to fill very well from the back side, so in the bow especially I have some filling to do. I will do as much as I can wet on wet. Start by grinding strips and excess epoxy down smooth, then fill gaps, then (while still tacky) lay down glass.

Will be running a wide strip of biax up the keel first thing so that its all better tied together. Took the molds out this morning, very happy with how stiff the hull is and how its supported.

[Admin - Shine]

molds and jig supports are all out, now just prepping for inside fiberglass.  

[Admin - Shine]

almost ready for glass, grinding out some putty that squeezed through strips, leveling out some of the strips. Will be trimming the strakes back so the are almost flush with the rest of the hull.

looks the same, but this is after grinding smooth the bottom section

[cvincent]

Nice progress on your boat. Will the stringers run along the side of the strakes inside the hull?

[Admin - Shine]

Yes, the stringers are located just outside the inside strakes.

Started glassing.

[Wej]

Looking really nice Joel!

[Admin - Shine]

Looking really nice Joel!

Thank you !

A little more progress.  Glassed the STB side chine.






Cutting out the transom core.  This is 1.5" core, it will be epoxied to the 3/4" that is there already.  After the inside skin on the hull is laminated, then the transom will be glassed in.





BTW, I have two extra sheets of this core. Its 4'x4' and 1-1/2" thick.

[Admin - Shine]

transom core is epoxied in place.

Dry fit, wet out surfaces with neat epoxy, apply epoxy glue (a mix of silica and wood flour), clamp/screw into place. both surfaces were very flat with a very nice fit, did not need a ton of glue. Used about 2 quarts of epoxy (before thickening)

[Admin - Shine]

I was planning on glassing the the bottom before putting in the transom, but unfortunately I had a bit of a setback. Last week we had a crazy downpour and one of my roof vents leaked into the boat. So I have to wait until the moisture content in those places comes back down before glassing. Its interesting just how dry the cedar was, some of its under 4%. Plywood, stored dry is 11% The places that go wet are no more than 8% on the cedar, but the plywood in the keel is 19% in one place.

[maxtork]

Sorry to hear about the roof leak. Set backs are inevitable but that one really stinks. Great progress so far though. That transom is going to be stout at 2 3//4" thick.

Quick question- when you wet out the transom prior to gluing on the core material did you thin out the epoxy to get it to soak into the wood better? I know you can do this with polyester resin but I have little experience with epoxy so not sure if a chemical exists that allows you to thin it out.

Keep up the good work. Grab a hair dryer or two and get that wood dried out! lol

Hi Max,

It is possible to the epoxy with just a little acetone, however I do not recommend doing so. Thinning it compromises the bonding ability of the epoxy, so while it make soak in just a tiny bit more, the next coat of epoxy (glue in my case) would not be bonded as well. West system published some data on bonding with thinning epoxy showing this. The only time I would thin the epoxy if if I was trying to get it to soak into rotten wood.

My warehouse is as hot as an over right now, and I have a fan running over it. After one day the worst areas had already lost 20% of the moisture
