YQ Bluenose by Johan [COMPLETED BUILD]

Hello Johan. This is a massive amount of work you have accomplished. I am very glad that you have found / are on your way finding a solution to the waterways. Like you said, this is the advantage of a group build where ideas can be shared and issues discussed. And we are doubly fortunate in that we have some master builders who can give guidance.
 
The last few days have little progress to show for. I occupied myself with adding the three keelsons to the hull. Instead of using the copper wire for representing the bolts in the keelson to frame attachment, I used toothpicks like I used on the frames, except where the keelsons are interconnected or attached to the keel. There I used nails instead, due to the assumed higher loads being transferred at these locations.
After completing the installation of the keelsons, I moved to sanding the inside of the frames. This proved to be a tricky job, a) there's almost no room to maneuver and b) it takes quite a bit of time ánd patience.

The three keelsons in place.

After sanding the inside hull, I started on the eight clamps, or floorbeam supports, running in longitudinal direction. At first sight one might be led to believe it's all pretty straightforward.
Again it's removing a lot of char, but it also requires quite a bit of beveling. The lines given by YQ are really a big help, but it still requires total focus on what you're doing.
While beveling these supports, I continually dry fitted them to make sure I didn't overdo the sanding.
Now the first clamp/support is bonded to the hull. Once the four upper clamps/supports are in, I will start on the sister keelsons. They are not part of the YQ build, but some of my predecessors, @Peter Voogt and @Canoe21, did add the sister keelsons and I think it's a nice addition, plus I want to do just a little more than what's in the build description.

Good to see, after all the preparations, you now can instal the inner beams. The hull will get her strength more and more.

This part was not fun, I remember that much!
You’re doing a good job so far!

Thanks for your encouragements.
I have this tendency to put things off I'm anxious about. Then, after overthinking things a bit, I jump into it, with fingers crossed.
With a "little" help from my SOS and DBBS friends.
 
Yesterday saw the installation of the second clamp. Not looking half bad, if I may say so myself.

And for the first time since the covid-madness began, we went to a concert of Hans Zimmer in the Ziggo Dome in Amsterdam. Great night with a great performance. Music form Pirates of the Caribbean, DaVinci Code, Dark Knight, Dunkirk, Dune, the Lion King, it was all there.

Picture 1: A nice couple, well placed.
Picture 2: A nice couple, well placed.
Both pictures made me very happy. :)

After a busy weekend, preparing for a service where I was to play the organ, enjoying Hans Zimmer's concert Sunday night and being busy at work yesterday, today saw some building activity on the Bluenose.
All four upper clamps are now bonded to the frames. It was a nerve wrecking experience. One has to apply about 27 dots of adhesive per clamp, then position the appropriate clamp, followed by adding a number of clamping devices to ensure proper seating of the clamp against the frames. Both the bow and the stern are the areas of concern, the stern more so than the bow. Towards the stern, the clamps need to warp in order to follow the contours of the frames, but not only that; the top side of the chamfer of the aft clamps has to align with the frame notches ánd it would be nice if one could maintain some symmetry between the left- and right hand side.

After installation of the clamps, I shifted my attention to the sister keelsons and the lower deck clamps.
For the sister keelsons I followed @Peter Voogt 's stunning build, in the sense that I will add the sister keelsons from the bow to the end of the keelson in the stern.
The sisters will consist of three separate pieces each, with splices in the vicinity of the keelson splices.
The picture below shows the dry-fitted forward twin sisters.

Since I had the fwd lower clamps already prepared, I decided to install both sister keelsons and forward lower deck clamps in one sequence. In itself the tasks are not overly complex, but having to use two hands, or one hand and a pair of tweezers, makes the bow area to be overly populated.
Luckily, after a couple of hours, I could declare succes.

As a very wellknown build log pointed out, it is beneficial to check whether or not the upper- and lower clamps are parallel to one another and to check whether the hull is warped or, very much preferred, still straight.
In the event of the clamp positions are not parallel to one another, it means removal and re-installation of the lower deck clamps. A royal pain, but doable, probably requiring the manufacturing of one or two new parts and some sanding.
A warp would prove to be more bothersome. To be honest, I wouldn't know what to do in that case, applying tension in the opposite direction of the warp while simultaneously moisturizing the keel is probably the way forward. If that would yield the required results, I don't know. Maybe some of the more experienced modelers have come across this phenomenona.

This is the picture cure I took to check parallellism and warp. For me, good enough.

And this is the completed installation of the fwd sister keelsons and the fwd lower deck clamps.

Now dinnertime. After that, we'll grab our bikes and go for an evening ride, thanks to daylight savings time.
Till next time!

Sisters here, Sisters there, Sisters are everywhere. :) (As a variation from another build log;))
Nice job, Johan.

Excellent progress Johan. You are right, just looking at the pictures there does not seem to be any warping present.

I can tell you Heinrich, it was a huge relief to see no warpage. Since I saw some fellow modelers having this issue, I was far from confident.
And I also learned that pictures are a lot less forgiving than what my eye-brain wants me to see...
 
The three sets of twinsisters are in. During installation of the twins, or rather after installation, I noted that my sanding job of the inside of the hull was far from perfect. This means that the six sisters do not show a nice, fluent flow from bow to stern. Two decisions were made, based on that fact: the sister keelsons receive the disposition "use-as-is". The second decision was to redo the sanding of th inner hull surface. Remarkably, that was rather easy; apparently the deviations were close to the keelsons and not on main area of the frames. Since I was at it, I also started sanding the outside surfaces. The weather was dreadful, so an appropriate job for the weather...

With some extra attention, your sisters are now laying nice in line, Johan.
