    That is the way I have envisioned it.

    My concern, is with the innaccessable contact surfaces between socket and shelf, and socket and the aft bulkhead. They would be "dry". It may not really matter, especially if there is solid contact. ie , no "lumps".

    The balsa is being bagged down on the deck as I type this-
    Four mm okume wemt on first, then 3/4 balsa ("I core", from merton's)

    Today was a workout!

    up and down the scaffold. I did it alone, because I had the window and no one was around to bribe. I hope I did it right, we'll see. A thin coat rolled on the 4mm; a thin hot coat rolled on the balsa (opposite the scrim side) let it sit for a while; a slurry coat troweled on the 4mm again (balloons and aerosil), layed it on scrim side up, bagged it, sealed the edges with liquid nails on the runwild part of the ply overhanging the sheers.

    Tomorrow, I will trim and fair it, and lay up the glass on Sat. I hope.:)

    Cool, it's starting to look like a boat! In the olden dayes we had to bag balsa upside down, then pull the scrim, do they make it epoxy compatible now?

    Yeah, I was told by several folks that the scrim is made to stay on now.There is actually very little to it-- fairly wide mesh, but thin, and strong filaments . I didn't have any pieces come apart, etc.

    You mentioned "print through" as a problem with your build... was it done scrim side up? How would you do it differently if you had to do it again?

    I heard the same about the scrim and thanks for posting this, Charly! It's like looking into a parallel universe for me. ;)

    She's coming out great! Board trunks, decks... before you know it, I think you'll have a boat!

    Thanks CatBuilder! You will be passing me pretty soon I imagine. Course then you will have the interior... my interior is pretty much done. (rough:D)

    I really wish I had the time to take the interior to a higher level of finish, but I am antsy to get those other two panels down from the wall-- they have been there now for several months. They seem to be well supported, etc, but I want to get them out and re-positioned as soon as possible. I will probably be cursing myself for not at least painting inside.. I know it will have to be done at some point, or something for uv protection, but it would have translated into another couple of months. It is a drawback of building in a small space.

    I spent the last two days fairing the sheers and glassing over the balsa deck.

    You guys were right about the balsa not fairing easily. Different densities in each block makes planing or sanding a fair line a challenge. Not to mention the dust. Any way, we got it to an acceptable level with a grinder, and a plane, then a belt sander then hand sanding.

    The decks got two layers of 17 oz biax with a sandwiched layer of 6oz uni running athwartships. I got the biax on sale, but it is only 38 inches wide. plus overlaps with the uni all made for an unperfect surface. Better to have done it all in one swoop with two 20 oz triax, ie, no seams

    the photo shows the peel ply draped on, (and a dirty shop);)

    Im hearing that tune "roll em roll em roll em"...

    I have been pulling my hair out over the moving problem, First I thought I could build a cradle on an "oxcart"-- some sort of wheeled contraption out of osb and galv pipes.... then I realized I have a height restriction at the garage door, which would severely limit my wheel radius.. so then I thought maybe rioll it out "Egyptian style" using some 4" pvc pipes and some kind of "training wheels" to keep her from tipping over.

    :idea: When all else fails consult the designer.:)

    So, the roll out party will be this Saturday. per designers suggestion I will tip her over on her side, atop about 120 two liter empty plastic soda bottles (caps on) and roll her out.

    There will be pics

    Rollout!

    This has to have been the most exciting and apprehensive operation so far in the project!

    I can now affirm that empty, two liter soda bottles work great when moving the hull about the yard. I had about 150 on hand. It takes longer than I thought to round up that many, but I was lucky to find an ally at the local recycling drop off.

    The triangular contraption is a "sled" that I tacked together to help slow the fall when rolling the hull over on her side. The idea was that it would slide over laterally, and the fetch up against the wall, letting the sheer contact it and then slide on down to the floor, atop the bottles. I was afraid to get a bunch of people in there, and ease it down by hand, since I didn't know how maneageable the thing would be, and I didn't want to squash anybody.

    It worked fine. The bottles held up, and the hull was easy enough to roll. At any one time, there were probably only one fourth, or maybe one third of the bottles actually bearing any weight. The trickiest part was flipping the hull over again outside then, onto her back. There is nothing to grab hold of. So, we levered her up a ways, blocking as we went till we could get up underneath. I think we had about ten guys at that stage. She flopped over onto some tires we had set out, without incident.
