  1. Thanks so much Don, Denis, John, Carl, Michael and the "likes".

     

    Don, I have to admit that it was less a matter of pre-planning than some trial and error on the first couple of frames that led to the seemingly organized sequence. :)

     

    Carl, the keel will be glued in place after the full frames are completed. This is how Hahn shows it in his book.

     

    Michael, since the keel is used to insure proper positioning after every couple of frames, the effect is the same, but without having to maneuver the frames between the jig and keel to get them mounted. BTW, judging from your results on Halifax, you wouldn't have had any problem, however you went about it.

  2. Time to get started on the frames. I've settled on the following procedure for doing them: 

    1) Remove the 9 parts for a frame from the laser sheet

    2) Remove the laser char from the joints between futtocks

    3) Using double sided clear tape, attach one layer of parts to the plan sheet for that frame, with the joints glued

    4) Glue the second layer of futtocks on top of the first

    5) Sand the faces of the frame until there is a fit to both the keel and the jig

    6) Fill any joints, as necessary, with filler made of sanding sawdust and glue

    7) Use strip wood to make any adjustment necessary to the keel notch on the frame

    8) do some preliminary fairing to both the outside and inside edges of the frame

    9) Treenail the futtock joints using the "drill and fill" method

    10) Apply Wipe-on poly to the faces of the frame

    11) Glue the frame into the appropriate jig notch using clamps to hold it in place and a straight edge to keep it square

    12) Use the keel to insure proper fit and spacing after each pair is set at opposite ends

     

    I've completed two pairs of frames now and so far, so good. The good news has been that using the laser cut pieces is a whole lot easier than cutting them all out by hand. The parts also fit the drawings fairly well. The not so good news is the amount of work necessary to get a snug fit  to the keel. Also, as I feared, the frame drawings and parts don't match up to the jig exactly, causing some need for further tweaks. All in all, I'm pretty satisfied with how it's going to this point.

  3. Grant, there will always be a front row seat for you.:)

     

    Michael, I originally received the resin parts, but remembered that they used to do laser cut wood and asked Ev at Lumberyard if they still had them.

     

    Glad to have you aboard, Anja and Steve.

     

    Good question Mark. The frame parts seem to match up to the drawings, so it's hard to know where the problem lies or how it will impact the build.

  4. Once again, welcome aboard to all. your interest is always appreciated.

     

    A few words about what I received from the Lumberyard, and about the direction that I intend to take. To begin with, this is a build using Hahn plans (included in the package), and the Hahn upside down construction method (a laser cut framing jig is included). The package contains laser cut framing pieces, including the keel, stem, stern post, rudder, keelson and frame futtocks. I ordered all of that in boxwood. There are various other laser cut pieces such as deck beams. I also got a sheet with laser cut pieces for the stern transom windows and carvings and the quarter badges and windows. The package also contains a good deal of sheet and strip wood in boxwood, pear and some other woods for planking and other purposes. In general, the laser cutting appears to be very good and the strip and sheet looks good, but not as smoothly finished as that from Crown. One potential problem looms. The jig and the keel assembly ( which I have put together) don't match the drawings in length. They do, however, exactly match up to one another. Hopefully, this means that the construction will proceed without difficulty, although yielding a model slightly longer than that shown in the drawings.

     

    I have obtained a copy of Hahn's book "The Colonial Schooner 1763- 1775" to assist in construction. It is my present intention to plank both sides from the wales up and to leave the lower hull unplanned, although I may decide to fully plank one side of the lower hull. I intend to detail the interior of the hull, with lower decking, partitions, etc. Upper decking will be left partially open to allow a view of the lower interior.

     

    I am attaching a photo of the jig, a rather poor photo of the package contents and a photo of the assembled keel. It's now time to get to work on the frames.
