Bill ( FAZE 5) recently turned up witjh a sailboard mast cut down to a nice little 3 piece. I decided that it fitted so nicely in the sail bag I would make some too.
the mast I'm using is a 4.3m mast which has a 49mm ID at the base.
I have cut the mast at 1.65 and 3.30m from the base.

The joining plugs will be 300mm long giving an overall length on each section of 1800mm which is the same as the length of the seat and the boom.
you will need 1500mmx50x50 of really strong wood eg RAMIN, TASSIE OAK, old growth DOUGLAS FIR(Oregon pine). I think Bill used Ramin. I am using 20 growth ring to the inch Douglas Fir. it comes from some 1945 army stretchers that had been stored in an air raid shelter until recently . they ended up at the tip and were rescued by me .cut into lengths of 2x300mm,1x700mm,1x200mm.
Always choose the correct saw as some larger tooth pattens may splinter the wood.
The cut ends are measured for ID then that is marked on the end of a 300mm piece of the wood. The square is rounded with a plane by 8 siding then 16 siding.
my choice of weapon is a lovely 1910 BAILEY /STANLEY No 7 with a 1920's sweetheart blade.
Next I sand the top 150mm to fit the upper section. This is how I cheat. be careful,especially if the fingers that are holding the wood are already missing some bits.
when fitted I sand the lower half so that it will fit up the tapered section and poke out 150mm. When the fit is good it is slid in with liquid nails on the lower half and rammed home with a broom handle.
this process is repeated for the next section.
the 700mm piece is rounded and tapered to fit in the base of the mast. the top edge of each plug should be rounded off so there is no sharp edges pressing on the inside of the mast.
when finished I waxed the exposed parts of the wood.
