    Yes, the link works for me. You know you can post pics direct from your phone/hard drive now? No need to use a 3rd party host. We laminated the stem today, much easier than the main frame. Next we make funny angles on the edges.

    Thanks mate - good to know. So its no longer a link to a third party....
    the forum must be hosting them somehow....?

    Got this in the post the other day - Vesper XB8000 AIS transponder. not for the nutshell.
    Pics a bit small.

    until you submit - and then its fine

    Flipped her over, feels nice to be at this stage. with Strip building this stage takes a lot of time to reach.

    popped her off the molds and onto the grass outside.

    Off with the molds and boat back on. from the bow;
    flipped from the front.jpg

    and underneath;

    will need to chock it up a bit better than that maybe - I'll wait to see if its necessary.

    Next - Quarter Knees, fillets inside, clean up the splinters and other scrapes caused by screwing together.

    Ni e work and good progress. We are still,shaping the main frame and transoms, not all that accurately, but it's being done by my 14 yo boy, sometimes on his own, so it's OK.

    The design is pretty forgiving i think. The strakes are over size, there's plenty of room for rough treatment.
    Its quite fun.

    Got some fillets on the inside. the work comes up messy against the white of the boards, but the fillets are fairly light.

    got out some material for the quarter knees. this is a bit of Australian Kauri.

    Bow knee material.jpg

    Trusting my bevel gauge and bench saw - worked out okay in the end.

    Forward knees in place. I also gave the transoms a coat of Epoxy, i was worried about the various fixed creating stains. i want to finish the transoms bright.

    Messed up with the first knee i installed.
    I didn't think the screw holes through well enough. i drilled through the transom parallel to the knee, which means the screw head doesn't lay flat against the outside of the transom.
    for the rest i drilled up at an angle, 90 degrees to the transom face.

    bit like this; A) Bad, B) Good.

    Dry fit of a rub rail.

    got the timber out of a big plank of DF i was given.
    the danger with recycling timber is nails - so i inpected very cafrefully before pushing it through the table saw and thicknesser.
    didn't detect an old nail buried deep inside - took a gappy tooth out of my thicknesser knives!

    overall - I'm not keen on recycling timber, the old holes all have rot around them. but rub strips are more or less sacrificial anyway. I'll dose the screw holes with some acetone i have on the shelf and then epoxy it all in eventually.

    I left the rub strips over size but couldn't bend them to the shape.
    I thicknessed down to the design dimensions and they bent in fine. I would say those dimensions are the maximum unless you are keen to steam them in or something.

    Music to my ears!! We are about to mount the transoms and mid frame on the building stock. We somehow cut the transom out with the slab of wood we'd made up somewhat crooked. So the glue lines have a distinct slant to them. Not to worry, the timber is quite dark, PNG Rosewood, and the glue lines barely show.
    I milled some Bluegum today, not at all the colour of yours, more a yellow/cream colour. Different variety, or local variation? Dunno.

    If you can adjust the knives lengthwise, shift one to the left and the other to the right. That way you can avoid having to resharpen the blades until it happens again or they're blunt. A lot of small thicknessers don't allow this but others do.

    very possibly Rick. I bought it a few years ago to make pedals for a pedal boat (which didn't quite work out).

    i do recall the guy at the yard noting distinctly that it wasn't NZ Kauri - so i have had it in my mind that therefore it was Oz Kauri.
    i meandered the WA Karri forests once - absolutely magnificent forests.

    I think as Peter said, there's Sydney Bluegum and tassie Bluegum, and they are not the same. Some we cut today is a bit darker, but certainly not red.

    We put our transoms on the frame last night, and it seems the bevels are all a bit out. Need to take a bit off the inside edges all around.

    Learning a bit more about the importance of careful measuring and marking today, as we transfer the plank measurements from the scale plans to the sheets of ply. By about the third try we got most of it right and the batten running fair. But man, those imperial measurements on the plans, and hand written 3s, 5,s and 7's often looking pretty much alike, it does my head in. Is that 15 and 3/16 or 13 and 7/16? And what the heck does a 16th of an inch look like? Oh and now it's 5 and 3/8! Bugger me sideways my head hurts!

    That's exactly my experience.
    I haven't had to use imperial since, with the single exception of thicknessing the rub rails - i used the dimensions as per the plans. I was struggling getting the upward bend at the stern, would take a bit off and try again. eventually i just went to the designed thickness and it worked.

    Port side rub rail glued on.

    Port side rub rail low shot.jpg

    That was a later shot, the baton extended beyond each end and i cut off once the glue had set.

    Rub Rail extend aft.jpg

    here is that side sanded back with the SB side going on.

    Port side rub rail sanded back.jpg

    SB side glued on, waiting for the overrun ends to be cut off.
    also note i left the cross piece on, not sure if it makes any difference, but i thought the rails, as i put them on, wcould push the boat out of shape. Maybe hog it a bit or something. so i err'd on the side of caution and left them there. The instructions say different.
    one side of the centre frame needs to be cut down to the gunwale.


    SB side rub rail glued on.jpg

    the cross piece had a screw covered in Epoxy, so using a soldering iron to melt it - i found a use for that valve sprint clamp i inexplicably bought for a dollar many years ago.

    The whole thing is looking more boat-like each day.

    Bugger.

    The pictures is a puzzle. sometimes they appear and other times you just get a line saying attachment.
    They seem to come back once the post has them edited back in.
    I'm pulling the images straight from my hard drive - do you think they'll only appear as long as i use the same computer or something?

    Applying the fillets does tend to get messy. You can reduce this by using masking tape first, or by scrupulously scraping-up the dripped bits immediately after, before they cure.

    Either option is better than sanding the dripped fillet material after. The filleting blend is quite hard. You tend to sand hollows in the wood around the dripped bit -- the wood is softer.

    Does anybody know if the Nutshell can be put on a swim platform with Weaver Davits? The kind that rest the dinghy on it's beam.

    I’m hoping the task set for Henry’s project is something like Explore and Exploit the Extreme Extent of the Gap Filling Properties of Epoxy.

    I just looked at that last pic, and thought Oh bugger, I should have faired the bottom edge of the garboard before I put it on. Face palm. But I think it just gets planed off flush with the bottom, rather than left as a lapstrake finish. Well, that's what's going to happen anyway!

    However I think the subsequent planks are to be finished lapstrake, which is not what I see in Trev's pics?

    Nice one Phil Y, i had a double take there for a minute - I though it was my boat

    I've planed all me edges back. i'll be beach launching quite a bit, and my boys will be thumping it about too - so I'm going to glass the outside i think.
    Plus, i didn't do a great job of my strake edges, so its a way of hiding that.

    Nice transom, what did you use?
    That centre laminated frame looks like hardwood - is it?

    I often use sanding dust form the belt sander to thicken my epoxy.
    Partly because I'm a cheap skate but i do like the idea of reusing - and i live in hope that the dust will match the colour of the wood.
    But you got to be careful with preparation i find. the saw dust will absorb the glue, so i liberally soak both mating surfaces before i add the thickened epoxy.

    Here's my dagger board case being glued up. i used micro balloons here, they do give a far neater fillet.
