Caledonia Yawl project: Gluing the the stern apron and stem laminate strips 

I had planned to glue the laminate strips in one go on Wednesday evening. But as things go when doing something for the first time, things take longer than expected. It was a cold evening and the epoxy was more viscous than I expected so spreading it on each laminate took much longer than I anticipated.

Caledonia yawl project: Making more sawdust

The process of cutting thin strips for laminations is a reductive one. As I don’t have a band saw, I’m using a table saw with a blade that is just shy of 1/8 thick. So for every 1/8″ thick strip I cut, I loose as much in sawdust.



I have just two more 2×3 boards to rip and I’ll have everything I need to glue up the bow and stern apron and stem.

Caledonia yawl project: Ripping Jig and other preparations for the stem and apron

To be able to get the 2″x 1/8″ thin strips needed to laminate the apron and stem I need nice clear (knot free) vertical grain wood. In my case that will be Douglas fir.

Last weekend I was able to find several 2×3 lengths that if ripped on its edge will give me 2.5″ wide strips that will give me the margin to plane down to the 2″ width specified. To do this you need to rip accurately, and the solution I found is to make a little jig that attaches to the table saw that should help yield consistent strips throughout the 8″ lenth. After each cut you move the fence over until the board stock rests against the jig guide wheel & repeat.

I also went back to the lumberyard to get western red cedar to build up my centerboard and rudder. I’m doing this while the strongback is free of the boat and I have a nice flat surface. That way I’ll get all my laminations done at the same time.

I’ve borrowed from the Gougeon Brothers and tu Gurit Embh. publications on wood foil construction.  Ian Oughtred’s plans and instructions in “Clinker Plywood Boatbuilding Manual” are good but basic and as water is so dense small improvements in execution should have dramatic impacts in performance.

Gurit’s guide also suggests that in testing stiffness western red cedar sheathed with three layers of unidirectional carbon fiber had a 67% gain in stiffness over just using mahogany.

Last scarf, moving on to the aprons and stems.

This weekend I was able to get back up to speed on my Caledonia yawl project after missing a week. I glued one of the two scarfs on strake 2 and will leave the other to do when I’ve got the station molds up as there is the most twist in the forefoot of strake 2 and it will be easier apparently to glue it down first and then do the scarfs.

It was then time to tackle the apron and stems of this Caledonia Yawl. I’ve decided to try the method of laminating thin strips 1/8″ of Douglas fir with epoxy and West system 403 microfibre additive. The part I’ve been struggling with is that in Ian Oughtred’s plans the apron is 2″ wide. So I need to find a stock of wood that is at least 2.25 or 2.5 inches wide so that after it is laminated I have a little margin to plane it down and fair it.

Punching through the plans to create a pattern for the mould that will be used for the lamination.

 

But all the standar lumber jumps from 1.75″ to 3.5″ and it seems wasteful to rip down a 4×4 timber just to get something 2.5″ wide. After a visit to a couple lumber yards I decided to get a few vertical grain clear 2×3’s and rip them along the wide edge to get the width of strips I need.

The stems are only specified to be 1.75″ wide and so I am able to use rough fir 2x4s to cut the lamination strips and I’ll have 1/4 inch of material to plane off and to keep it true.

After using my full sized plans of the bow and stern apron and stem to punch through all the reference points onto my pattern board. I traced it all out again.

Video from my panel discussion at the IMTM 2015 FuTurism.com conference in Tel Aviv

You can now see the panel discussion in which I participated at the IMTM 2015 FuTurism.com conference in Tel Aviv on Feburary 11th.
The moderator of the session was Jonathan Mieri who is a digital entrepreneur who started the app Superfly on the panel with me were:

  • Amir Halevi, director general for the Israel Ministry of Tourism,
  • Li Baochun, deputy secretary general for the World Tourism Cities Federation,
  • Gideon Shmerling, spokesman for the Tel Aviv Yafo Municipality
  • Jenn Sander, head of global initiatives for the Burning Man Project.
  • Ido Ahoroni, the consul general of Israel in New York was slated to be on the panel as well but unfortunately was not able to attend.

The topic was broad “Mass tourism and Viral tourism” and other than some preliminary discussion with the moderator as panellists we did not get much more direction than that on the focus of the discussion. I tried to think of my fellow panellists and the audience in my contribution to the discussion by focusing my answers less on the what I do at Tourism Vancouver as an energy specialist and more on the why am there doing the work that I do.

Here is a direct link to the Youtube post for the panel discussion on mass tourism in which I participated:

From Tel Aviv to Vancouver learning from each other

I had the great fortune to be able to participate in the FuTurisme.com conference plenary discussion on mass tourism and the future of tourism at IMTM 2015. I was there at the invitation of Tel Aviv Global which is a municipal corporation tasked with promoting the economic development of the city attracting investment and developing tourism.
One theme that was very prominent in their strategy is to leverage the tech start up ecosystem of the city.
The conference had 42 travel related digital startup companies pitching their ideas and vying for the mayor’s digital travel award.

Getting a tour of the startup ecosystem in Tel Aviv. The big questions seemed to be that starting things was happening in an organic way but holding on to the dividends of that innovation was the challenge. Keeping successful startups in the city and making sure international investment was not just pulling the human capital out of the city.

That evening I was invited to a cocktail at city hall with the mayor of Tel Aviv where they unveiled a commemorative stamp of the city. Tel Aviv has been recognized by UNESCO as a world heritage site for its white city collection of Bauhaus architecture. It also recently was recognized by UNESCO as a creative city in the digital sphere and they are running with it as a branding element for the city.

The Tel Aviv Global team also came up with a wonderful idea to put a call out to students to volunteer as local hosts for the conference speakers. This was an opportunity to meet someone with an interest in your subject matter, but also they acted as ambassadors and sometimes interpreters or even personal assistants. I found it to be invaluable and rewarding, helping me develop more insights and broadening the conversations I had.

Suite à la publication de l’article dans Skift que j’ai poster récemment. J’ai reçu une invitation a participer a un congrès de tourisme international a Tel Aviv le 10 et 11 février. Avec tout juste un mois de préavis je n’étais pas sur que l’invitation soit sérieuse, mais après un échange de communication au ralenti à cause des onze heures de décalage.  Ils m’on confirmer qu’ils cherchait réellement à me fair participer à une colloque avec le ministre de tourisme de Israël, le consul général de Israël à New York entre autre. Le thème est de discuter le future du tourisme et l’impact sur le développement durable des destinations. Je vais parler de mon travaille et le contexte qui le met en valeur a Vancouver.
