Finishing and fitting the new Centreplate Case Capping
(Page 4 of 4)
This last page illustrates the finishing of the
replacement centreplate case capping and the final
fitting to the boat.
Drilling the fixing holes
After marking out the position of the eight fixing
holes they were drilled out and countersunk. All
marking out was done in pencil on the under-surface
of the capping.

Positioning the capping for fixing to the
casing
Two wooden jigs were constructed to wedge the
capping in exactly the right position whilst the
fixing holes were drilled into the underlying GRP
of the casing.

Drilling the fixing holes in the GRP of the
casing
Using the jigs to hold the capping in exactly the
right position, the pre-drilled fixing holes in the
wooden capping were used as guides to drill into
the underlying GRP of the centreplate case top.
These were then ready for the eight 12 gauge
self-tapping stainless steel screws which hold the
capping in position. The screws are 1.5" long.

Finishing the capping
Before finally screwing the capping in position on
the centreplate casing, some final finishing was
carried out. The edges of the capping were roughly
bevelled using a plane.

Sanding smooth the edges
The roughly bevelled edges were then sanded smooth
with a sanding block. Finally the wood was given
several generous coats of Burgess Woodsealer

The finished capping in place on the boat
After attaching the stainless steel stop-plate, the
completed capping was then screwed into place using
the eight self tapping stainless screws.

The final check!
With the boat launched it was time to see if, when
the centreplate was lowered, the arm and attached
shackle cleared the capping. The photograph shows
that this has been successfully achieved by welding
an extension on to the original arm. The steel
stop-plate at the back of the slot protects the
wood from being damaged when the plate is let down.
All objectives successfully achieved!
