  1. Ocracoke 20 in OZ

    Thanks Alan for your detailed reply. I tried what you suggested and discovered the highs were voids full of epoxy. I then tried larger pads in conjunction with pressing the sheet down with my hands a bit harder (to help expel any excess/pooling resin) before torquing the screws. Problem solved! Also helped tightening the screw in the middle of the planks first then working outwards (helped squeeze the excess resin out the sides).

    Thanks Paul, most of my holes were pre-screwed and surfaces cleaned prior to applying glue. Possibly some debris could be coming off the perimeter of the holes though. After meticulously fairing rib bands and inner layer, its so dissapointing to have the final layer coming out so terrible.

    Gents, im having some issues glueing down my 2nd layer of planking. I've dry fitted everything and it feels really nice and fair. However, when i apply glue and screw it down, the result is a bit lumpy upon removing the screws. Not sure whether they are high points between the screws or low points at the screws. Im talking 0.5-1mm and speculating enough to cause a fairing headache. Not sure whether im torqueing the screws down too much? Too much glue or trapped glue? Im getting a good epoxy squeeze-out and using a notched trough to try and apply evenly. And feedback appreciated. Thankyou

    You are doing a great job with the hatches and waterproofing. Do you have an ideas how to glass the edges of the exposed bulkheads? I though about vac bagging any sharp edges to avoid the need to round them off, then build them up again (e.g. chine edges).

    The possums have been a good intermission for my lack of updates :-) How is she looking?

    Lotus, also worth considering using a uv stable polycarbonate/lexan as opposed to an acrylic. My current catamaran boat has lower windshield made of acrylic with upper shield made out of polycarbonate. After 10 years of service (offshore fishing) the polycarbonte has outperformed the acrylic in both long term clarity and durability (the acrylic now has a crack, and its thicker than the lexan!).

    hehe - I can imagine the fire works when the wife gets home!! :-)

    Progress! albeit slow. Went with a meranti bottom, stringers and transom. Test fit of the chine flats today. Onto topsides soon and switching to Joubert Okoume for this, and the remainder of the project. Have started thinking about the glassing. Pondering how many layers to put on the keel for protection/abrasion resistance, yet not cause a fairing nightmare. My regular crew never fail in scraping the bottom of boat at the ramp when I am off getting the vehicle :-)

    That colour blue will look nice out in the sun. What paint system did you use?

    Thanks for your advise PAR - it allowed me to continue progress today. A few of the planks were already glued down with really tight joints and some glue starvation as you mention. I opened them up with a thin hacksaw blade and refilled with epoxy. I feel better they are properly edge bonded now.

    Guys, please can i request some help/advise! I'm well into the planking (1st layers) and i have done such a good job with scribing my plywood planks, they are butting together so tight that i am getting quite a glue starved bond between plank edges. Is this a problem? Is there an ideal gap to aim for? Or not considering the 2nd layer will overlap the joints. Thankyou

    Looking really good Lotus! I wish I had such progress to report on. I like the tip re breaking into sections. At least if feels like you are getting somewhere when you can see the results in a particular section. I have never faired a boat before, however I have done heaps of epoxy windsurfers, and in recent times, we have been faring them by 'wet' sanding. Mostly to cut down on the terrible dust and stop sandpaper from clogging. Also seems to 'cut' a bit better. I use mini long board with sanding belt for the sandpaper. They last forever. Use the usual 'guide' coat as well to spot the highs/lows. Could this method be on a boat? At this stage of the project, I wouldn't think waterproofing should be of a concern? I.e. a light spray of water.

    Superb! I'm looking at the rib bands and speculating how you are going to finish the inner top sides. Personally, I think either covering them or leaving exposed looks good.

    Looking good Lotus. What is your method of flipping the boat?
