Joining vertical round battens for in-mast furling mainsail

[haydude]

On a previous thread I asked for information about the battens for an in-mast furling mainsail.
I received lots of useful information and now I have all the correct specifications. I know which product to buy for the battens from Bainbridge that for my sail size of 55 square metres is 8mm diameter round batten.

Due to the very long size of some of the battens (12 metres for the longest) initially I debated whether to have the battens as joined segments for easy handling and storage or as single size. I decided for the single segment and guess what? Bainbridge has 10 weeks wait to get the longest reel that would allow to cut them to the full size. Shorter segments are available in stock. Good enough to have only 2 segments for the longest battens.

So now I have one further question around joining the battens. Bainbridge says that they do not have any product to join the battens.

Please could you let me know what is the best way to join 8mm diameter round battens? And if I need a product, which one, and where to buy it from?

GRP tent poles are joined using short lengths of metal tube as sleeves, maybe 3 inches long. I use them for my sun awning and the curve made by each pole with four joints looks pretty smooth to me. I think the tubing is aluminium.

FRP sail battens are made using the "pultrusion" process, bit like extrusion for FRP!

You could join them using some thin walled metal tube. However, speak to these guys http://www.rbjplastics.com/standard-profiles.html they are a UK pultruder of these smaller sized profiles and could help you.

I have some you can have for free. Need to check suitability.

The batten for my furling headsail have 8 mm carbon top joined to 8 mm fiberglass bottom.
joined with a piece of SS tubing and spring pin to lock the tube to the pole.
