Mast rebuild 5

Today was a hard day, I shaped the mast. It went from a long hollow box covered with glue to a tapered oval all done by eye. I started off by using the power plane to cut the excess material away until I had a even sided cleaned up box. Then I made centerline marks on all 4 sides.


Now comes the hard part, take everything away that shouldn’t be there and leave just the mast. First you use the electric plane, then the hand plane, then the sander and finally hand sand it. A labor intensive job that took about 5 hours.




After that I repaired a couple of knots that were in the wood and gave the mast a coat of penetrating epoxy and added the final shims at the top of the mast.




The joints came out pretty good (for working on saw horses behind a building) and the mast is really “shaping” up nice!

    Have you been able to determine cause of failure?

  3. The main cause was a failure in the old glue joints at the top of the mast. I had repaired one of the joints (and it didn't fail) but the other ones did.
