I had been struggling with setting the camber in the panels. This is an ingenious device!

If you bother to follow it, you will find that it works very well.

I'm sorry but I thought it was a very poor tutorial.🤔

Flaxbybuck,

It refers to an earlier post mentioning the Claudio device and how to make panelled sails. This is one of the videos that post refers to.

Er? Shouldn't that be Head nor Foot Flaxby?😁

Sorry Tiggy, but I couldn't make head or tail of the video. 🤔🤔

You can use 6mm double sided tape to fix the luff tape down. Works very well. Available from most stationers or Amazon.

Hi Jim
I have used the "Claudio Gadget" to make my yacht sails. There are videos on U-tube if you search the name. Makes sails of the correct camber and I found easy to use and has never let me down.

I favour using a jack-line in the mast and attach the sails using stretched out dress fasteners. If the sails are terylene or man made fibre (ripstop nylon) the dress fasteners can be superglued in place.
Sails for the Aeronaut Bella are made like this.

Hi all, lately I have made my own sails, not panelled ones but simple material. In UK there is something called wunda web. It is a gossamer thin tape but is actually glue. You can find it in the old type drapers shops or where cloth material is sold.
I make up the sail by washing the material and then ironing it dry and then spraying with starch. This makes it stiff and you can draw on it.

For a triangular sail the longest edge should run with the weft of the cloth or non-stretch edge. Allow enough extra width for 2 seams i.e. one fold and then another. Use a steel ruler to make the folds as sharp as possible. Then feed the wunda web into the folds and make the 2 folds and iron them flat. The glue will melt and hold the seam in place, I have sails 10+ years old with no sign of coming apart.

Nylet can supply eyelets with backing washers of small sizes for the corners, they can also supply a metal punch or drift with a machined end protrusion for the size of the eyelet. Perhaps for the smallest eyelets you might want to reinforce with the merest amount of super glue.

If you do not line the sail up as above with the cloth you will get an unwanted fold appearing in the sail when it is in place.

It is a quick method especially for the likes of me with no sewing machine skills.

Competitive sails are made from multiple panels, as by doing so you can produce the right shape for the sail that you require. Each panel rarely has a straight edge, so that when the panels are joined the sail forms a natural curve. In competitive sails that curve can be induced into different parts of the sail for whatever you want. So if you want a light weather sail you might chose to have a full belly, i.e. a big curve in the lower part of the sail, a storm jib though might have absolutley no curve in it, as it will be dealing with a strong wind, and needs to be as flat as possible. The science of sailing and sail making is truly an art, and there is nothing short of experience to tell you what is right.

A friend has successfully used Balsalock to turn the edges of a sail and glue them down. The sail edge is turned over and then ironed down. 😉
