Flinder´s bar
(Extra)
If ordered four cylinders (305 mm, 152 mm, 76 mm, 38 mm length, all 78 mm
∅
) are seprate included to
delivery. The Flinder´s tube is fixed to the binnacle column and in it there are four wooden spacers (280 mm,
140 mm, 70 mm, 35 mm).
The Flinder´s bar is used to correct the longitudinal field (B
2
) caused by the ship´s weak iron. The first
adjustment of Flinder´s bar on maiden voyage remains preliminary because the latitude influence cannot be
established at that time. When passing the equator at first sufficient deviation data has to be collected to allow
the final adjustment. On locally operating vessels like habour tugs or in coastal fishery a Flinder´s bar is not
necessary.
Open the Flinder´s tube by removing the upper plastic cover. For adjustment lift up tube to allow access to the
weak iron cores and the wooden spacer pieces. Loosen the tube by unscrewing the fixing screws at the upper
and lower Flinder´s bracket. Refer to the illustration below.
