    Default Goat Island Skiff (yawl) build in Perth, West Oz

    Tacky. It helps to avoid creating problems with the first layer when you tug and push on the second to smooth out the bumps and creases. I imagine it also promotes better saturation into the wood, but I could be making that up.

    Yes ... I normally try to tease up a corner of the first layer as a test before proceeding with the second. I want the feeling the first layer is just held down a little. Otherwise you end up with two layers sliding all over the place.

    If you get a wrinkle in the first it is just about impossible to get rid of.

    Thanks MIK and David
    I went with your advice and waited until the first layer went sticky before dropping the second layer on. I've applied another two coats of epoxy on wet on wet to fill the weave backing that up with a skim coat of fairing compound. I'll wait for it to cure overnight before sanding and recoating to ensure a smooth surface.

    And now the photos. ..

    Glass checked for size.

    I found a 4 inch metal scraper the most useful for this (my plastic one melted in the acetone )

    Second layer on and wetted out, just needs a trim now.

    That's all for now.

    G'day again

    I trimmed the excess fibreglass off today and sanded. I then followed this up with another coat of epoxy, unfortunately this highlighted how much work I still have to do to get this board fair.

    So I applied another coat of fairing compound and I'll wait for it to dry and sand again.

    With fairing goop (much smoother)

    I'm trying to get the board as smooth as possible before painting, otherwise it'll take forever to get a nice finish on it; especially as I plan on painting it black.

    Cheers Dan

    G'day again

    Well I've got the port side of the board all nice and smooth now. Time to start work on the starboard side.

    My main issues with getting the board smooth and fair stemmed from the initial glassing of the board leading edge up. I did the glassing in the second half of the day to prevent any bubbles, unfortunately my garage door points east providing sub-optimal lighting for picking up runs. So when I move onto the rudder I'll setup some decent lighting to try and sort it out.
    Additionally, are there any major issues with filling the weave using the epoxy fairing compound? I think this'll do a much better job of it and I'll throw another couple of coats of epoxy on afterwards to make sure it's well sealed.

    I used my rudder as the practice piece for each step of the process. Of the two blades, I would rather have to remake the smaller one. Plus, the rudder is far less important for performance so if I screwed up the shape or the finish, I'd be less inclined to try to make it perfect and could just apply the lesson to the major foil.

    G'day again

    Work got in the way a bit this week but I managed to finished fairing the dagger board, next stop glue up blank for the rudder. Unfortunately work is back in full swing again so my build rate will drop significantly. That being said I'm hoping to launch by a December (summer) this year.

    I'll tackle the masts the way you suggest David, starting off with the boomkin before making the mizzen etc.


    The finished board minus paint. I'll wait until the end before painting as I'll spray as it makes more sense only to set the spray booth up once for everything at once.

    Cheers Dan

    Hi Dan, Just checking in. Looks like you are well on your way to figuring out epoxy. It's almost magical stuff. I noticed the small sanding block on your board. If that's what you are using to fair there is a better way with a longer block say 300mm or so. This will span lots of bumps at a time and do a better and quicker job of fairing.

    G'day Simon

    I was using the small block to smooth out the top end of the board, for most of the sanding I've been using a 1/3 sheet sander initially followed by a 70cm ( 2'4" ) torture board. I've been using the yellow Norton sandpaper as the white stuff has non clog additives on it. It's been working well and I can get it in 25m rolls.

    No further progress over the weekend as house commitments got in the way. I might be able to get stuck in again next weekend.

    Cheers Dan

    Back again
    Work has decided to get in the way again however I've now got the next couple of weekends free to work on the boat. So far this weekend I've glued up the rudder blank and smoothed it with a power plane now to sand it down and shape it. uploadfromtaptalk1361064660051.jpg
    This has been running concurrent with setting up my shed (built a workbench 4.5m long 80cm wide, with overhead wood rack), and putting up lights and picture hooks for the wife etc.

    I'll be ordering the paulownia on Monday, dressed to size and shipped across a continent comes to a bit over $400 ($100 of that figure is shipping), still cheaper and lighter than wrc. Since I'm adding weight in the form of the yawl modifications, I've gotta pull weight out elsewhere (always a difficult proposition). Must resist the temptation to use the jarrah (850kg/m^3) I have lying about (maybe a small insert in the breast hook) .

    Cheers Dan

    G'day again.

    Slow progress but I've managed to get the rudder blade shaped. I had a bit of tear out when planing in vicinity of the scarfs but nothing some lightweight filler and wood flour can't fix.

    uploadfromtaptalk1363004977353.jpg

    I also had the paulownia rock up last week, well packed and all intact so a big thumbs up to Whitewood.

    I'll get some glassing done this week but we'll see how work goes with regard to further progress.

    Dan out.

    Howdy,

    I would be REALLY interested to get a weight of this, the second Paulownia framed boat. Have you already chatted with Bruce about where he used the Paulownia?

    He worked quite consistently to keep weight out of the hull through the building process - lightweighting is really more of a consistent process of trimming weight at each point of the build - and got a hull that weighed in at 105lbs.

    This is actually quite good even for something carbonish composite.

    Best wishes
    Michael

    No pressure eh Mik?

    It will be difficult to lose the weight of the additional mast steps required for the yawl build, but I've got a few ideas on how to drop some weight.

    1) All mast step boxes will be made of 4mm gaboon ply. 33% reduction.

    2) Gunwales and inwales made from cedar vis Oregon. 10-15% reduction.

    3. Mast steps made from lightweight meranti (400kg/m^3).

    4. Considering drilling out inwale spacers and framing to lighten. However I'm not sure if the extra epoxy required to seal will add more weight than I save.

    5. All framing material paulownia.

    6. Can I shave down any of the framing stock or am I courting disaster?

    I'll still tape the chines and epoxy IAW the manual.

    I've not talked with Bruce but I've studied his log which is full of great ideas to drop weight.

    Cheers Dan

    Let me lighten the weight I just put on your shoulders!

    You are doing more than I would!

    I really meant more like making sure excess epoxy doesn't go into the build. Some see epoxy in the bottom of a mixing container and think ... where can I put that.

    The reality is that the boat is strong enough already so there is nowhere for extra epoxy to go!

    Sorry I sounded like high expectations!

    Commenced glassing the rudder today.

    Just the tip (Archer reference)
    uploadfromtaptalk1363484357653.jpg

    I'll finish off the glassing this week and then I'll have to take a 2 month hiatus for work.

    Cheers Dan
