CUTTING THE MANDREL TO LENGTH
The mandrel (16) should be re-cut of exactly the same length of the one having been
cut off from the boom profile.
III 9 b 1 – Remove the bearing holder (19)
+
bearing (17) assembly from the rear end of
the mandrel (16).
III 9 b 2 - Cut the mandrel (16) at its rear end with the same method as the one having
been used for cutting the boom profile (15). Same as § III 9 a2. File the rear (cut) end of
the mandrel and foot track ends smooth.
Caution : the forward (drum) end of the mandrel (16) must not be cut !
III 9 b 3 - Fit again the bearing (17) and bearing holder (19) into the cut/rear end of the
mandrel. Tap at M6 (6mm) at 30 mm from the cut end. Fit and tighten the screw (29).
III 9 b 4 - In case the mandrel has been cut a little too short, the fore and aft play must be
reduced to a minimum. To do this, loosen screw (29), push the mandrel forward, pull out the
bearing holder (19) so that the washer (20) touches backwards, tighten again screw (29).

FITTING THE MANDREL ONTO THE BOOM
III 9 c 1 - Fit the mandrel (16) into the boom profile (15), fit the washer (20) and the drum bearing (18) onto
the stainless steel pin (36) inserted in the drum boom end fitting (22).
III 9 c 2 - Check that the mainsheet bails (25) and boomvang hound (28) are properly fit in the bottom track
of the boom as shown on drawing 12.
III 9 c 3 - Slide the bearing (17) located at the rear end of the mandrel (16) onto the stainless steel pin
inserted in the rear boom end fitting (23).
III 9 c 4 - Completely insert the rear boom end fitting over the rear (cut) end of the boom profile (15). A
ratchet tie down strap is a handy tool to do this.
III 9 c 5 - Drill holes
∅
5mm at the rear end of the boom profile (15) through the pre-drilled holes of the rear
boom end fitting (23). Fit the corresponding pop rivets (37) supplied into these holes to permanently attach
the boom end fitting onto the boom profile.
