  1.  

    Almost exactly a year ago I decided to build the little ship's boat that comes with the kit (I wasn't going to start for main ship's build but want'ed to play).  I got part way on that fiddly little boat but ran into some challenges.  

     

    One for PdN builders to be aware of I documented in a PM to @Azzoun.  It has  to do with the spacing of the rib formers on the keel.  He posted it the info here.  

     

    Although I pushed on with the boat build for a while I had great trouble getting decent results.  Partly it was a problem trying to bend the 1/16" square basswood but mostly it was my lack of experience and patience.  I put the little boat on the shelf.

    Unfortunately (or not?) things don't always stay on shelves where you put them.  The little boat skeleton was broken in a fall so I put it further back on the shelf where is has stayed for months.  Thinking I would abandon it I saw that Model Expo sold the kits for these little boats as stand-alone projects.  Since my assembly instructions called it a 5-Incn Typical Ship's Boat  I order the 5" version from ME.

     

    Here is a comparison of the 2 laser cut sheets for the original (top of photo - from my PdN kit), and the one just received (bottom one on photo)IMG_2870.jpg.a06d3e81cf3526593cf22c0db29fbeaa.jpg

     

    here is a comparison of the 2 partially assembled

    I think this is a clear demonstration of the expansion of the universe.  - the new 5" boat is much larger that the old one - what other explanation could there be!

     

    Advice for little boat builders.  If you're building the one from your kit firstly measure the spacing of the rib formers on the keel before building the jig.  Secondly look carefully at rib former #1 (it's labelled) to make sure that it is smaller that the other 3 - mine isn't and it makes it impossible to plank the hull.  Thirdly if your rib former #1 is the correct size realize that using the building jig which makes the top of these formers (top when the boat is in floating orientation - bottom in construction orientation) level will leave a gap preventing you from attaching the rib to the keel without some shimming.

    Fourthly, consider throwing out the basswood 1/16" square stock and using some wood that takes bends more easily (I'm using walnut). Fifthly, don't expect to get the lovely sheer line shown on the plans since the building jig makes the run from rib 2 to 4 level (probably not big issue).

    I'm going to build the bigger one before I decide if the smaller one can be salvaged by some changes to rib former #1.  Otherwise it will be back to ME for the 4-1/4 inch boat which I believe is the size in the PdN kit

     

     

     

     

     

  2. I have a ropewalk on order and was looking for yarn for experimenting.  I have a supply of fine linen and cotton yarns from our home weaving studio.  The finest is labelled 28/2 which yields 7200 meters/kilo. I checked our sources for weaving yarns and discovered 90/2 (27,200 m/kg) , 60/2 (18,000 m/kg) and 35/2 (10,600 m/kg) lace linen in black and in natural.

     

    These are sold in small spools of about 250 m for around $8.  One source is Vavastuga located in Massachusetts.

     

    Once I receive the ropewalk and the lace yarn I will do a few experiments and post some results.

     

  3. Hello Jack,  I’m enjoying watching you build.  Everything is coming together beautifully.

     

    I have one question about your simplified planking technique.  I see in the last photo that you allow the plank to stop at its natural width whether or not it is ona bulkhead.  I see what appears to be a small support under one of the planks.  Do you add a support under each of these places before you attach the triangular filler plank?

  4. I have a question of technique. 

     

    I have started to shape the spars and have an issue with the yards.   I need to taper both ends.  I've done one end by chucking the dowel in a drill and sanding it down.  Now I'd like to flip it around and taper the other end.

     

    Problem - if I put it in the drill chuck the nicely tapered and will be marred (crushed).

     

    Looking for techniques to accomplish tapering on that 2nd end. 

    Thoughts:

    1 - sand by hand instead of drill - this is the fallback solution but I'm a bit lazy and don't want to do all the hand sanding.

    2 - wrap the end to be chucked to prevent crushing the nicely tapered 1st end - I tried this using tape - no good, and then by wrapping some brass sheet around the dowel - still crushed.

    3 - try to find a collet that can fit in the drill chuck and can take the dowel and hold it firmly - the dowel is tapered to the collet doest grip it well.

    4 - buy a lathe that allows the yard to be inserted so the appropriate collet is holding the middle of the yard where it isn't tapered - my preferred solution except that it is expensive and would introduce a longish delay.

    5 - ask MSW gurus how else to approach the problem

     

    I'm going to try #5 1st and failing that #1 for now and #4 eventually (got lots more yards to taper over the next few years!)

     

    How about it - any suggestions?

  5. I've been remarkably slow in getting this launchway built.  I blame the weather.

     

    The plans for this require a board with a set of timbers to create the incline.

    Then the timber frame is built with additional keel supports every 2nd timber.  The ship will be held in place with a pair of brass rods inserted into the keel.

    Not shown are the support timbers that will eventually (appear to) support the hull laterally.  They'y won't be added until the hull is ready to be permanently fixed to the stand.  I've opted not to embellish the stand to make it look like the ground around the launch way.

     

    I'm not totally confident in the strength of this as a stand but if necessary I can add some additional support to make sure the timbers don't become unglued by stress.  Part of the problem with weak joints to date may have been that the shed where I assembled it first was not heated and perhaps the glue was too cool to set well.  I'll see how the regaled timbers survive some handling.
