Jacques,

I admit that I am not too enthusiastic about 3-D-printing these batten ends for junkrigs. You will soon find that the shown batten end fitting lacks a hoop or something for tying on the sail itself.
The photo below shows the leech end of the battens for Ingeborg’s sail. Crude, maybe, but quick, simple and strong. The bolts also let one lash the sail’s leech flush with the batten ends.

There is another, even simpler way, which I have seen in Stavanger: Both batten ends were just given biggish holes where needed. After grinding off any sharp edges, the sail was tied directly to the battens via these holes. The bolts for tying on the sheetlets were kept, but the owner didn’t bother with those chain stubs.

With the 2-3mm Dyneema lines available today, this direct sail-to-batten connection should hold forever.

Jacques,

As it happens, I am designing a deck ring assembly for another JRA member, to suit a 7 inch tube which is very close in diameter to your 18cm mast. The components are to be 3D printed in suitable plastics for outdoor use. He is planning to join a 200mm tapered tube to this 7 inch tube as indicated in the drawings, but it would be just as good to make a hybrid mast using the 7 inch tube, or just to use an 18cm tapered tube as you are doing.  Would you be interested in joining the project? 

Hello David, 

I am interested in joining these project ( File N° 1).

I printed "30mm+aft+end+plug.stl " - file enclosed- What are the 2 drillings for?

Good day

Jacques 

Are you just interested in batten ends for the moment? Can you make your own designs to print? If not, just let me know the size of your batten tubes, and then I can do it.

There is a rounded end to the hole going forward, so that when the sheet span is put through the other hole and tied with a figure 8 stopper knot, it never leads around a sharp edge, whatever point of sail you are on.

Hello David,

I begin my rig ( and batten ends) : please find enclosed photo . I think it's necessary to secure the end piece( yellow) with a rivet (or bolt)or glue it with epoxy. what do you think? 

Good day

Jacques

Bonsoir Jacques,

if you don't paint the aluminium mast and battens, it will stain the sail. That's all. It is a decision of aestetics, not function. I did not paint my Ilvy's sail, and it works fine. Maybe with a new sail in the future I would paint it, but it is not a must.

Cheers

Paul
