Details

1370 mm long. Made of high modulus UD carbon fibre for best possible stiffness for the weight and diameter. The 1370 mm length weighs approximately 80 grams.

12 mm diameter for approximately 870 mm with 500 mm of tapered section. The section goes to 12 x 5 mm at the very top. Designed to be the upper section of a mast for a Marblehead or Ten Rater with 14 mm diameter round tube for the lower section. This provides high fore and aft stiffness in the upper section combined with low windage. Use off-cuts for booms.

Side bend in tapered tubes: The tapered tubes are checked for sideways bend. The distance that the centre of the top of the tube deviates from a centreline through the lower half of the tube is measured. A deviation of less than 1 mm is considered ‘straight’. We no longer have any ‘straight tubes’ and do not anticipate having more deliveries. While stocks last we can offer tubes with a deviation of 1.5 to 2 mm at a discounted price (40% off the full price). The price you see here is already discounted by 40%.

  • Cutting carbon
  • Always wear a mask when cutting and abrading carbon fibres.
  • Clear up the work area carefully afterwards.
  • Use a wet rag to mop up carbon dust rather than a vacuum cleaner or brush.
  • Before bonding
  • Check each piece of mast tube for bend.
  • Arrange to use them so that the bend in the mast will be forwards going upwards.
  • Abrade all surfaces to be bonded with abrasive paper
  • Use Acetone, alcohol or methylated spirit to clean all surfaces to be bonded.
  • Bonding
  • Use liquid epoxy to wet all surfaces to be bonded
  • Then add thickened epoxy to the surfaces that will be bonded
  • Avoid applying local pressure that may distort the parts during bonding
  • Avoid raising the temperature of the work piece until the epoxy is cured
  • Allow the work piece to cool gradually after post curing.
