November 2019
After many hours of hard graft by the Kerne Engineers,
volunteers and curious enthusiasts we can now report that following the removal
of the affected 60 stay tubes (plus several smoke tubes to gives us extra
working room) the thread re-cutting of the tubeplates and re-gauging is finally
complete. This has been something of a marathon job requiring skill, patience
and brute strength over a period in excess of 12 months, but now we move on to
the next critical phase – the threading of the new tubes. The tubes have
already been swaged out to the correct diameters (the smokebox end being
slightly larger than the combustion chamber end) and are now on their way to
precision engineers together with the gauging tool. The gauging determines the
relative start positions of the threads on each tube, so it was necessary for
us to record the gauging results for each tube and these readings enable the
engineers to cut the bespoke threads for each tube. We now await the outcome!
In the meantime swarf and other debris that has ended up
inside the boiler as a result of the thread cutting has now to be cleaned out. Away
from the vessel, the new smokebox bottoms are under construction, but we shall
probably leave installation until we have finished the tube job.
Above the Boiler Room there has been a great deal of
activity in the re-fitting of the
Wheelhouse from its appearance as a storage shed to more like the operational
area it should be. The ships wheel is back in its rightful place, and various
mountings and shelves that support equipment such as the echo-sounder, radio,
GPS, Engine Room voicepipe etc have now been installed. In addition, stainless steel
drip trays have been installed below the BECLAWAT sliding windows. These have stainless
steel drains which discharge outside of the structure. Whilst the original
wheelhouse did not have these drains, it was clear that the deterioration of
the previous structures was the result of water getting past the rubber seals
and accumulating on the horizontal timber members behind the interior cladding,
so these improvements should extend the life of the rebuilt structure. The next
major task in the Wheelhouse is the installation of the timber decking within. In
order to ensure an adequate air gap between the boiler casing and the timber
deck, we plan to bolt angle steel to the front and rear bearers and to span
these with timbers lying fore and aft. This will ensure that the deck timbers
are short and light enough to be lifted and removed therefore giving easy
access to the top of the casing for maintenance and painting.
As reported in an earlier bulletin we had managed to acquire
a superb Wardroom Oil lamp which the Mate had refurbished. Thanks to the generous
donation by Bill Edmondson, a volunteer on the Ffestiniog Railway who saw the
first-acquired lamp on our Facebook page, we now have two such lamps. Whilst not
by the same maker, the lamp donated by Bill is virtually identical, so we now
have two beautiful additions to our Edwardian Captain’s Cabin.
So, whilst we now await the arrival of our treaded tubes, it
is time to get into the Christmas Spirit (although I personally prefer beer!!)
Merry Christmas and a Happy New Year to all.
