August 2014 Keel Repairs Continued
After replacing the keel of the bow in 2013 most of the work
has been concentrated afterwards on other projects.
This summer a start was made with the painting of the
complete under water ship and the hull.
After the underwater ship has been scraped from the antifouling
paint and base coats a further inspection was made of the keel.
The stainless steel rubbing stroke was removed from the keel
between two supports, it was noticed when the stainless steel strip was removed
that sikaflex was standing like little mountains on top of the strip indicating
that there were cracks in the wood.
The wood was cleaned and indeed there were some cracks in
the wood and the sikaflex covering the bolts was loose. But the things did not look
too badly.
A layer of Priomacon paint was applied as protection. Upon
further inspection after the paint dried the wood did not looked to good.
Since it looked like that the cracks were not too deep it
was decided, to use a router and remove the wood which was in a bad state.
There is approximately 20 mm wood removed till wood was
found in the keel with only hairline cracks.
Wood was cut to seize and dry fitted it was slightly thicker
and the depth of the groove, to be able in a later stage sand all smooth again
with the original height of the keel.
The next step was to glue with epoxy a new piece of wood in
the large groove made in the keel. The good thing was that the cracks were only
ion the middle part of the keel and not running into the sides. The new wooden
strips were hold in place with screws alto to make sure when screwed ion place
that excess of epoxy was compressed in the little cracks left in the keel.
When all was dried the new wood was sanded to the correct
height of the original keel.
Screws were removed.
The screw holes were drilled out and filled with wooden plug
which were glued in place.
All was sanded again and painted several coats with Primacon
In a later stage the stainless steel strip will be glued
back again with sikaflex and stainless steel screws.
