    Default Second Garboard Strake

    How to fasten the second garboard strake while glueing? So far I’ve gotten along without any metal fasteners, but this one is eluding me.

    I have scoured the internet but all I’ve found are pictures of the strake screwed to the keel. Is there another way, or are screws it?

    If this is the second, how did the first go on? I fit one so tight that it stayed in place while I grabbed the screws and I removed one the other day where all of the bronze screws had melted away. Why would you not want to connect the garboard to the keel?

    Default Second Garboard Strake

    On this boat, the strakes are connected to the keel with epoxy. The key point here is that I only have one side glued on at this moment, and I cannot get clamps around the other one.

    Improvise clamps using scrap battens longer then the garboard is wide, and cord to pull the ends of the battens against the plank. Then some slender wedges between the batten an plank to harden it up. Do a dry run to practice and ensure that the cord strops are the correct length.
    A couple of temporary nails to ensure that the plank does not slide about on the glue would be a good idea.
    It really is quite difficult to build an ugly wooden boat.

    You will probably need some boat gripes as the build progresses

    Blocks of wood and gently tightened ratchet clamps can do wonders. Careful to not over-tighten! What design is that? Watching with interest

    This is Ian Oughtred’s Elf. Loving the process and it’s certainly a learning opportunity!

    So, can I do the extended wood clamps against the keelson?

    Yes, just make sure that the end on the keelson is grippy enough not to slip off due to the angle. Do a dry run to check it out.

    As Nick mentions, you need movable ribands to clamp to. The cloths pins work well for double or lap streak planking.

    Some people appear confused as to what this is. Glued ply lapstrake with just three big wide strakes. At least I'm assuming it is lap. No chines, no stringers. I suggest you get used to temporary fastenings, and recommend truss head pocket screw style. You don't need a lot of them.

    Or go ahead, if you insist, make really long clothespins. They will want to slide off. Maybe stick some sandpaper on the tips.

    There is a variation on glued ply lap that uses stringers, but I don't believe this is it.
    Ribbands not so much associated with small craft lapstrake.

    Totally right. I can use some small screws to temporarily hold the strake while the epoxy sets.

    Unfortunately I have a new problem. it seems the unopposed torque of the port garboard strake has bent my entire strongback so that now the keel is no longer straight. Trying to force it back into shape hasnt been easy...

    Has anyone seen this problem?

    No, most people avoid the risk by keeping everything symmetrical and hang strakes in pairs.

    Well you have two or three more pairs, sol a lesson learned for the rest of the build.

    Haha yeah, just hoping I can straighten it out in order to put the second on. Not really sure how to go about that!

    Temporary countersunk screws make great clamps. Permanently intalled screws are better. Fasteners keep the wood from starting to slip off the epoxy and the ply from delamminating.

    Can you bolt the jig down to the floor? Spanish windlasses applied where they will do most good might pull her back.
