...twin Wood Duck 12 build...

fairplay · 31 Jan 2012 8:39 am

...as my work-table is a little over six meters long and a Wood Duck 12 has about 3,66 meters in length i thought i'd try to build two of the at the same time...

...step #1 - unpacking - always fun:

...step #2 - assembling and preparing stuff to glue:

...step #3 - glueing stuff:

...the puzzle-joints worked out quite nicely:

...i am not yet sure if i really like the puzzle-joints; from a technical point of view they are great and result in perfectly aligned panels...but i am not sure that i will like the looks of it...we'll see ...

...was able to start with stitching the twins:

A flotilla of boats on their way - I look forward to seeing the launch regatta!

I like the puzzle joints. I think they are an elegant engineering solution, and look good on the presentation side.

...ouffh! - about two months have passed without any progress...however, i was a little distracted when we went onto a nearby frozen lake and i stumbled upon this:

...i even managed to track down plans for this little boat...perhaps a new project for autumn ?...

...now, this week i finally had a chance to do some work on the twin Wood Ducks, stitching them up:

...during the stitchting session i realised that shaping the ducks is more difficult than it was with the Pax...especially the bow and the stern needed a lot of persuasion and extra-support in form of extra-holes and extra-support-structures:

...luckily also another little box arrived in time with stuff that helped a lot for todays task:

...so today i was able to finish the tacking of the twin-ducks:

(Pax no. #2 - still waiting for his new deck to be attached - smiles from above to the new arrivals)

...a little progress - predrilling the hatch-cutout:

...cutting the hatch:

...first half:

...supporting the cutout:

...learned that the support forms are very close the hatch-cutout:

...dry-fitting the cutout:

...the saw i was using has a special feature that makes cutting curves easier by moving the blade a little back and forth all the time - unfortunately this also caused the wood to chip. When i used the saw on the second Wood Duck without the curve-cutting-feature the cut was much cleaner...lesson learned...

...got a chance to glue the hatch-cutouts:

...could finish another step in the build - glassing the inner hull...

...as i am covinced that - to make a strong lightweight hull - you need two strong layers and one soft layer inbetween, i deviated from the manual and glassed the lower inner hull completely, not only the cockpit area...

...my belief is also supported by the fact that epoxied glass is strong when being pulled but not when being pushed, which means if - for example - an underwater rock hits the boat, the layer that takes up the most energy and needs to resist to prevent breaking is the inner hull, not the outer hull or the wood inbetween...

...cutting and laying the glass:

...the filleting and glassing came out pretty nicely, still with a little bit too much epoxy:

fairplay · 10 Apr 2012 12:15 pm

...plan for today - filet, glas and epoxy the deck-underside:

fairplay · 11 Apr 2012 7:23 pm

...deck-underside fileted, glass-striped and epoxied:

...and footrest glued onto cured-second-epoxy-coat of the lower hull:

fairplay · 9 May 2012 10:22 pm

...ooops, seems i left out some steps here...ok, i have an excuse: i dropped my MacBook mid-operation from one and a half meters and it did not survive that treatment...so it seems a few photos got lost...

...progress today - glass and first epoxy on the decks; cutting the glass:

...first layer of epoxy:

...acutally, it's a thin layer of epoxy :

...leaving a few threads to be cut when the epoxy starts to cure:

Looking good.

Ouch for your mac! You could probably recover the data from the hard drive though. The drive unscrews fairly easily and you could then plug it to a working terminal.

fairplay · 10 May 2012 9:15 pm

...hey beaker, thank you for the hint...

<OT ON>
...actually the drive is in an external case for two weeks now, and the data is being recovered bit-by-bit as it is barely possible to read complete files from it anymore...

...some data is lost unrecoverable - for example from the iPhoto library i was only able to recover about 70 GB of a total of 85 GB before - while a lot of (for me) important save can be saved...
<OT OFF>

...so, today i finished the third coat of epoxy on the upper deck...

...even while i was working very carefully there will be a lot of sanding needed later on, as there are a couple of runs i couldn't catch in time...

...next i plan to reinforce the the stern and the bows outer hull with little pieces of glass and epoxy hoping they will withstand scratches and damage from careless handling better...

...just installed the coamings on the twins:

fairplay · 16 May 2012 8:43 pm

...had a little time to spend on the coamings today...

...sideview onto the second Ducks coaming - and the underside of the hatch-covers that i also did while epoxying the coamings:

...view over both Ducks:

...used two router-bits to shape the coamings - a straight one and a rounded one for a nice smooth touch:

Fairplay, It's all looking good. Have you set a launch date?

fairplay · 17 May 2012 8:53 am

...hey Phil, thank you! - i hope to be able to get them wet before may 29th...varnishing is planned for monday to thursday...depending on the weather that is...

...just finished the preparation for the end-pour and will now start mixing the epoxy:

...ouffh! - a little more than a month later the Wood Ducks finally saw water for the first time!...

...unfortunately i did not have the time to make any more photos during the last steps; after extensive sanding sessions the hulls were washed with water and laquer-thinner and then varnished by spraying five - very thin - layers of varnish, sanding in-between all the layers by hand with waterproof-paper...

...after applying the last layer of varnish i had to leave for a couple of days - time, the little ones used to grab the boats, carry them to the lake and get them wet all by themselves ...

...when i came back yesterday i added a little detail on the boats regarding the hatch-covers: i tried to used a magnet-based-mechanism to keep them fixed into position, which seems to work very nicely...

Congratulations, they look very handsome. The finish is beautiful.
