FRIENDS VISITING

Friends been visiting 16 January 2021 bringing lead from Peter Ny and Epoxy from Nils Malmgren

Here are two videos Petter made one Captain Grahn made one. Captain Grahn and me sailed an old Abin Vega to Florida 2007 Captain was 19 at the start. We are still friends.

MORE STRIPES

Hi Friends.

Progress has been strightforward so far but now I have reached the bilges and building speed is slowing down.

I have been clamping the stripes down and inward but for down I need longer clamps and its at a slant so they slip. I solve it by help contraptions it just getting  a bit more interesting.

Before I made 1 stripe on each side every day now its one stripe on one side a day.

Soon I be over the bilge and then speeds pick up again.

SCARFING PLYWOOD

Hi friends.

Here is a video showing me scrafing 5 cm strips of 2.4 meter long plywood.

I do it on my table saw. I use a piece of wood to get the desired glue angle. After some initial trials I found the way.

8 stripes build 5 cm of the planking. So far I can do the boat round in one day. In 5 days its 25 cm high.

The table saw used for scarfing behind Exlex to the right of the green bandsaw. A pile of stripes rest on the jig redy to be used for progress

A BEGINNING

I have now two stripes of 5 cm planking all around Exlex the Canoe Cruiser. The second was a bit more easy as I had the first one as support. Also I had learnt a bit how to handle the pieces. The plywood is 2.4 meters long hence a lot of scarfing, 3 on each stripe on each side. 12 scarfing so far, but I am learning. It goes better and better.

BENDING 15 MM BIRCH PLYWOOD

Hi Friends.

Today with the help of Peter we cut 2 sheets of 15 mm birch plywood into 5 cm strips. 6 cm was the original idea. I cut one 6 cm strip with the jigsaw to test the bending. It worked and I cold have bent it more with some force but take it easy. Therefore 5 cm was decided. It was easier to twist and less angle to twist.

Not a good idea to glue the planking to the molds. Previusly I put tape on the frames to isolate from the glue. Today I split PVC hose. That will also be kinder to the real composite boat so I thougt I might as well test it now on the mock up.

Below one picture.

The photo shows one 5 cm strip of 15 mm birch plywood temporarily attached with clamps. Also a split PVC-hose on the stern to insulate from glue. On top of the molds the 2 sheets of plywood cut into 5 cm strips

THE JIG DONE

Today I completed the jig.

Paradoxically, its seams that the boat going to give me lots of space at the sme time it do not take up very much space in my workshop. The is plenty of space for me to do good work.

I am very happy with the lines so far.

Now I am going to clean the workshop and sweep up the sawdust before cutting up the 15 mm birch plywood into 6 cm stripes.

Below are two pictures. Click once or twice to enlarge.

And one without me.

I am going to try to get a phone that has a camera with a wide angle lens that better can show my new boat that is longer.

PROGRESS ON THE HULL JIG

Hi friends

There is good progress on the hull jig.

Half of the molds are now on the strongback and me I think it looks fine.

Below are some pictures, click once or twice to enlarge.

A tiny string helps me to center the molds left and right.
The molds one side
The molds the other side. The hull will be symmetrical fore and aft. I will put the rudder on this side for no special reason than that previus boats had aft this side. The lines seams to be sweet.

Also Sailing la Vagabonde have published a video interview with me done in the Azores. We also spent some time together in Porto Santo. There is many comments.

RESTRAINING THE MOLDS SIX DEGREES OF FREEDOM

Molds and other rigid bodies have six degrees of freedom. They can change their position forward and backward (surge), up and down (heave), left and right (sway). Translation in three perpendicular axes, combined with changes in orientation through rotation about three perpendicular axes, often termed yaw (normal axis), pitch (transverse axis), and roll (longitudinal axis).

When setting up the jig it is important that the molds are rigidly fixed in all the six movements movements.

The aluminum profiles take care of the up and down movements and roll.
The lengthwise markings on the aluminum profiles takes care of the forward back position and yaw.
The centerline takes care of the right left movement. The plumb bob takes care of the pitch.

Its good to be careful and make strong hull jig because each plank adds to the pressure on it. There is a concrete flor in my workshop. It is strong.
Below is a picture of the aluminum profiles fastened to the floor.

THE MOLDS ARE DONE

I started to cut the middle mold from 18 mm spruce plywood supplied by CEOS. Then I did the ones fore and aft. To my surprise the had more beam. The joy of my idea to mirror the aft part of the model had clouded my thinking. Of course the widest part of the boat was not in the middle but a bit aft.
A step from the beaten track and you are a child in a new world. There is always something to go wrong when you try something new. The world is to complex to be predictable. My molds had brought me back to reality. If at once you, fail try again.
The easy fix was to make the middle one a copy of her neighbors. When the hull is lifted of the molds it bulges out in the middle anyway a small bit. So that takes care of that problem.

Here they are. All af them. This will give me  a more roomy boat. Exlex 2018 had an inside beam of 96 cm Exlex of 2020 has an inside beam of 114 cm. That is realy sufficient. Exlex the Canoe Cruiser will get an inside beam of 122 cm.

CRISTMAS HAS BEEN SAVED

Today i borrowed a big van from Håkan and drove to CEOS in Norrköping and loaded a big pile of plywood. Thanks CEOS for that, more about that later.

Peter helped me to get it into my workshop.

Peter with his plywood car. The first run was with one sheet. Later with succes he became braver and loaded her with six 18 mm pieces.
Me on the CEOS-plywood Some are for the molds some for the boat.

I also got new ideas for the lines. I cut the parabolic stretched model in the middle and put her on a mirror and played around a bit. Slowly as I watched the images from a distance it became very clear that mirroring the aft end was the ansver especially taking a Cape Horn passage into consideration.

The left one is the aft partit got more stability and is better for the higher orbital flow that exists in stormy waters. It also give me more space for the doors or hatches to the central dry part of the boat. Rolling the models on the bench indicates the better stability
An other photo of the two half models. The ast part to the left. The boat will thuse be symmetrical for and aft like Bris a boat that I in the 1970 and 80s made many ocean passages in.

I have also changed the layout. Below is picture of my notebook.

There is two bulkheads with waterproof hatches dividing the boat into three parts. The middle one is nice dry and cosy in all waether the for and aft ones is is for navigational purposes handling sails and such. The outer ones are 2.4 meters long The middle cosy one is 2.8 meter long. My bed and office is 1.9 meter long 0.8 meter wide. The dining and recreation room is 0.9 meter long. The sailing full scale wooden mock up version will decide the final layout. There is plenty of deck space in this version.Good for conserving leg muscles. There is 3 mast. The forward ones side by side like the 2018 Exlex. It worked well.
