    I started working on a model of my sail, but I finished the actual sail first after only completing carboard templates of the model's panels. The big one is fun, crawling around on the floor with a measuring tape and pencil, I felt very clever and accomplished. Arne's instructions are very clear, follow them step-by-step and you won't go astray. Any doubts I had were relieved with two mantras I often repeated: "Make one to throw away", meaning that I could always call the first one an educational exercise and make the "real" one later if I really screwed up. The other was "how bad does it have to get before it won't work at all?" to remember that a bedsheet hoisted up a log will work as a sail for awhile, and people make sails out of plastic tarps and duct tape. The only way to fail is by not starting. Good luck!

    Yes, there's not doubt about the fact that Arne is a pretty slick sailmaker, but if he hadn't tried making the first one, he'd still be going to a sailmaker now!  I'm  completely with David on this one: sailmaking is relatively easy to learn, especially for junk sails.  Indeed very, very few of the sailmakers that I know ever had any formal apprenticeship and more than a few taught themselves.  Making sails is really satisfactory work: clean materials, not working bent double in a confined space, no nasty chemicals, out of sun, wind, rain and snow and requiring little in the way of specialised equipment.  And best of all, every other person who is intimidated at the thought of making their own believes that you are some sort of superman!  If you are nervous about wasting expensive fabric, make a scale model out of a nice light material and stick a model mast in the ground to play with it!

    There's really no need to be intimidated, Dennis. Look at it this way: almost all professional sailmakers in the world know less about making a junk sail than you now do, if you've looked at Arne at work, and read through the info scattered around this place.

    And the professional sailmakers have to charge you for the time it takes them to climb up the learning curve to the point where they are competent to make a junk sail. Time is money for them. For an amateur, time invested in learning a useful skill for a sailor to have, is a good investment. If you can make it, you can mend it.

    It ain't rocket science. It always surprises me how many people will go through the whole process of building a boat, mastering all the many trades involved - except one of the easier ones, sailmaking.

    Hi Antoine and Dennis

    I am sorry if my photos discouraged you. I didn’t mean to be smug. Remember, there has been a first time for me as well. Actually, when I made the 32sqm blue cambered sail for Malena in 1994, I spent less time on that job (around 40h). That was because I used ‘Amateur Method A’ which was much quicker. Also, the rope type boltrope I used then, which was hand-stitched onto the edge of the sail, came on faster than the webbing I use now (triple-stitched). I remember that I roped that sail in 8 hours sharp, and that included splicing in the big hoops at each batten end  -  24 short-splices. What I saved was the fitting of corner loops plus all the little black webbing loops at foot and head and at all the batten ends. The webbing type boltrope is ‘for everyone’   -  if you can ‘drive’ a sewing machine, you can rope the sail.

    It is quite a mental struggle to start such a project, I can see the point with that.
    The main thing you must master (to some degree  -  you need not be an expert) is the sewing machine, and the machine must be able to handle fairly thick thread.

    This time I decided to loft every panel onto cardboard templates first. It is better to make the errors (which I also do) on paper.

    My lofting procedure this time went like this:

    I started with one of my master sailplans with AR=1.90. This was scaled down so that batten length B=4.90m (instead of 5.077m in the master sail). After having re-calculated all the measurements needed for lofting, I could clear the floor in my living room and set to work:

    1.      First I lofted the parallelogram shape, common to panel 4-7, and added the calculated round onto the cardboard. The cardboard template is the net shape of the panel, so when laying the template onto the rolled out cloth, another 20mm was added for hems etc.

    2.      All the panels 4-7 were cut out to this template  -  there was not room for lofting and sewing at the same time.

    3.      Then all panels were hemmed where they should (Panel 7 even along the foot).

    4.      Then I started sewing the panels together along the battens. I use staples for basting them together.

    5.      With these panels assembled (and all staples removed) I put this section aside.

    6.      Lofting ‘the transitional panel’, panel 3 was done by reshaping the template for panel 4-7, and the sail was cut out from it. This time I had to add a little corner as the cloth (163cm?) was not wide enough. Triple-stitched flat seam was used. This adding of cloth was of course also needed on the following two top panels.

    7.      Lofting panel 2 (from top) was done onto fresh cardboard and starting with the triangle shape, shown on Sheet 2 of the sail plan, and the panel was cut out from that.

    8.      Finally, panel 1 was lofted by reshaping the pattern for panel 2.

    9.      Then the 3 top panels could be assembled, much in the same way as the lower section.

    From there on it was a question of adding all the bits onto each section  -  surely a lot of sewing, but still easier work than the lofting.

    Finally the two sections could be mated along batten 3 and the last bits fitted to it.

    The Odyssey III which I used, is a wonderful, amateur-friendly material to work with, and the use of my  amateur method of joining the panels means that there is no need at all for passing big rolls of cloth through the sewing machine.
    To spell it out slowly:

    Anyone who can sew a handkerchief
    can sew a junk sail!

    Cheers, Arne

    PS: No doubt my string of photos has left black holes of  (lack of) info, so just ask if you need to have details explained.

     PPS: Antoine, I will use 50 x 1.5mm battens for the two upper ones plus the boom. For batten 3 - 6 I will use 35 x 2mm tube. I haven't quite decided on the yard yet.

    PS3: I uploaded a photo of the thread bobbin to the same album. The needles are size 110 (/18). The sewing machine is of the ordinary domestic type, so the needle socket is called 130/705 H.

    Hi Arne


    You seem to have mastered the whole process ! Nice work.

    It is a little bit intimidating seeing you work your way throught this as easily. I suspect I will struggle much more when the time will be to start my own sail (which, by the way, will be almost exactly identical, as it fits pretty good what WaterBear needs).


    If you don't mind, I have a few questions :

    you said in other thread that you use 35 and 50 mm Ø battens. Is the 50 is for the yard, or for the 2nd battens (I think remember you said once that this batten has to be strengthened) ?

    What kind of stropes do you use for webbing ? (heard that car safety belt could be used)

    What needles and sewing thread are you using ?


    Thanks


    Antoine (WaterBear)

    Tonight I finished the new sail for Ingeborg. I haven’t kept record of my use of labour. I have worked every day since I started, but some of the days I just worked for two hours, so my guess is that I spent between 50 and 70 hours on the job. No major setbacks. The sail actually came from the same roll as the sail for Frøken Sørensen in 2013. The photo album has so far risen to 40 photos, mostly in chronological order, and all with captions.

    Today I started the construction of a new sail for my Marieholm IF, Ingeborg. It is happening in my living room. Although there is barely enough floor space for it, I think it will encourage me to get the job finished, hopefully within 2  - 3 weeks. I start with the lower section, panel 4 – 7. Here it pays to make a paper template first. I may even use templates for the upper panels, to avoid making errors directly on the canvas  -  we’ll see.

    Instead of making a write-up about it, I this time just take photos as I go and upload them to a special album under my member’s albums.

    Cheers, Arne

    PS: Here is Ingeborg’s sailplan.
