Repair and Maintenance of a Drascombe Lugger
Drascombe Lugger: Constructing a replacement centreplate
case capping (page 2 of 4)
Having decided that Sospiri's capping was beyond
further repair, the first stage of replacement was to
take careful measurements from the old damaged capping.
Several modifications were planned to protect the new
capping from being damaged when the centreplate was let
down.
Constructing a replacement capping: Measuring up

The damaged capping
Picture shows the damaged teak capping. The slot to
allow the head of the steel centreplate to swing up
through the capping shows damage at the aft
(bottom) end where the pin of the shackle has
impacted into the wood either side of the slot.
Extending the arm of the centreplate should solve
this problem. The wood had completely split into
two pieces from the slot to the end of the capping.
The two halves had been crudely glued back
together.

Sketch plan of Lugger capping
Figure 2. Sketch plan of capping with the
dimensions marked. To prevent the centreplate and
shackle damaging the replacement capping it was
initially decided to reduce the length of the
slot. However it would need to be shortened by
about 3 inches which would mean the plate could
not be fully let down. A better solution is to
weld a small 2 inch-long extension on to the end
of the centreplate arm and this has now been
done.

Sketch plan of 'Stop-Plate'

stainless steel 'stop-plate' which will be fitted
at the end of the slot in the wooden capping. The
plate will be made of two 0.25" thick stainless or
galvanised steel plates welded together.

The drawing was sent to a local steel fabricator
who was able to make the part in stainless steel.
Here is the result which cost 5 UK pounds!

Constructing a replacement: Additional considerations
Note that the dimensions in Fig. 2 (above) apply
to Sospiri which is an early Mark 2 Lugger.
Dimensions probably vary on later Luggers and may differ
according to manufacturer (e.g. Churchouse or Honnor
Marine). Anyone considering replacing their capping is
strongly advised to carefully measure the existing
capping before opting to construct or purchase a
replacement. If purchasing a replacement double-check
with the supplier that it is compatible with the
measurements of the existing capping.
