Rejoining a Mast

    My mast was cut in two pieces before I acquired my W28.  I am preparing to rejoin it soon and was looking for hints as to the process.  The previous owner had two internal aluminum sleeves machined which makes things a lot easier, but I'm still trying to figure the best way to do this.  

    Also, the spreader brackets have been cut off and I must come up with something in that department as well...

    I've watched Yves Gelinas repair the mast on Jean-du-Sud, a 30 ft Alberg.  It appeared that he used an epoxy and I believe he said, "Glued, Screwed, Riveted, and Bolted."  That immediately presents four questions... What type of glue?  What size & type of screw? What size & type of rivet? What size & type of bolt?  (OK with conjunctions, 7 questions).

    Stainless or Aluminum?  A friend in Australia recommended Monel rivets dipped in tef-gel and 1/4 inch rivets.  

    Pics of my mast are here, .

    Any advice would be appreciated.

    I would recommend using aluminum rivets, and epoxy glue.  Rivets spaced about 2" apart.

    Thanks for the info... What size rivets would you recommend?

    I don't know what is available to you locally, but I would say 3/16" or 1/4".

    I really hadn't thought about this much, until reading this post. But it a short piece of internal sleeve of the appropriate size would seem like a great spare to have aboard for anyone doing long-distance cruising. 

    Were the masts consistent enough through the various Westsail model lines to make this feasible add-on to your parts inventory?

    I'm curious who else might be interested in purchasing such an item. It would certainly be more economically feasible to create these in volume than one-up.

    Not too feasable an idea.  There were too many different mast sections used, from four different mast builders to make it practical.  The ones I have seen done, and some by the mast builder, use sections from smaller masts, cut apart and bent to fit as well as possible to the inside of the mast. 

    A piece of wood carved to match the inside of the mast section would work, and could be fabricated locally most anywhere you happen to be where you can take down and work on a mast.
