■ RIGGING, ATTACHMENT TO LOWER UNIT

If no turnbuckle is required, attach the rod marine eye directly to the integral toggle on the 2.5.

If a turnbuckle is required, it must terminate in a marine eye that will fit directly to the integral toggle. Use a Navtec C560

turnbuckle or similar for rod with either a

/4" (19mm) pin diameter.

/8" (15.9mm) pin

■ TOOLS REQUIRED

Sharp Hacksaw, Sandpaper, Small Triangular File, Heat Gun, Razor Knives, Sandpaper.

■ SUPPLIES REQUIRED FOR GLUING FOILS

Rigging tape, blue masking tape, 9430 Hysol Epoxy (supplied), Scissors, mixing cup, mixing stick, glue brushes, acetone, paper towels cut into quarters, plastic to cover splint area, clear packaging tape, wood alignment stick and placemat-sized table covering.

Alignment Splints - Use 90° angle extrusion to make splints.

Sides to be about

/4" (19mm). Cut extrusion into 8" (203mm)

lengths and remove burrs from cutting.

■ RETROFITS, FITTING ROD

If you plan to reuse the existing rod and turnbuckle: Lower End—If you are using a standard Navtec turnbuckle

with integral toggle, the lower body must be replaced with a standard Navtec marine eye body. Check to make sure that this eye will mate with the Harken integral toggle. Two cross pin sizes are available. They are the same size as the clevis pin. See above.

Upper End—You must take apart the marine eye so that you are left with a threaded nosepiece. Check to see if this is pos

sible. If necessary, contact Navtec or Riggarna for correct pro cedure. You will slip carbon foils over this threaded nosepiece. If you cannot remove this fitting you will need to cut the rod.

■ HEADSTAY LENGTH

Note: When cutting rod to length or making up new rod, make sure that you can take apart the rod terminal (usually the top eye) so that you are left with a threaded nosepiece.

Make up the rod headstay or adjust the turnbuckle so the Harken toggle fits below the rod terminal eye. The pin-to-pin

distance of the Harken toggle is 3

/4" (83mm).

Note: The 2.5 Carbon furler has an integral toggle. No additional toggle is required below the furler.

■ FOIL CUT LENGTH

The Carbon 2.5 furler has an integral toggle. No additional toggle is required below the unit. To check the foil length, lay foils alongside the stay before cutting top foil. Make sure

that turnbuckle is set to desired length.

■ TOP FOIL CUT LENGTH

Instructions for worksheet below: 1 Fill in total pin-to-pin headstay length. 2 Fill in A length. 3 Adjust B length if necessary.

Note: There must be enough space between top of carbon foils and bottom of rod terminal to allow for turnbuckle adjustment. As turnbuckle is adjusted, terminal is pulled down towards top of rod. If no turnbuckle is used, there only needs to be

minimal space—

/2" (12mm)–between the carbon foil and rod terminal.

We have put 4" (100mm) as a starting point. This may need to be adjusted based upon how turnbuckle was set when headstay was measured. If there is less than 4" (100mm) “take-up”, less space can be left and vice versa. The space between foil trim cap and bottom of turnbuckle must be more than “take-up” on turnbuckle.

4 Add A, B, E and subtract from total pin-to-pin headstay length. SUM = _________ 5 Choose the number from foil multiplier below closest to, but not greater than,

sum from step 4. Fill in D length.

6 X 72" = 432 6 X 1828.8mm = 10972.8 7 x 72" = 504 7 x 1828.8mm = 12801.6 8 x 72" = 576 8 x 1828.8mm = 14630.4 9 x 72" = 648 9 x 1828.8mm = 16459.2 10 x 72" = 720 10 x 1828.8mm = 18288.0 11 x 72" = 792 11 x 1828.8mm = 20116.8

5 Add A, B, D, E. Subtract from pin-to-pin length for C (top foil length).

IF YOU HAVE SHORT TOP FOIL

If top foil is less than 8" (203mm) do not use a recessed top connector. The top foil must be at least 4" (101mm). If it is less, shorten the upper 72" (1.83m) foil to make the upper foil 4" (101mm).

CUTTING TOP FOIL

Once you have checked the top foil length by laying foils alongside the rod, use a sharp hacksaw to cut top foil. Tape foil and cut along tape. Sand bottom end of the foil so it is square and to remove any carbon burrs. Lightly sand inside of foil where it will be bonded with 220 grit to remove any grease or mold release agent.

PREPARATION FOR ASSEMBLY

Tape outside ends of all foils using blue masking tape. To make sure tape edge lines up with end of foil, extend the tape over foil end. Use a sharp razor knife to trim tape even with foil.

Coat rod with mold release agent or wax to keep epoxy from adhering.

Heat rod terminal and remove threaded screw and threaded nosepiece. If rod terminal has been upset (peened), follow Navtec or Riggarna procedures for removing peening.

Tape threads of nosepiece and tape nosepiece so it will not slip down foil when pushing it back out.
