CREST Bulletin July-Dec 2017

During the second half of 2017, CREST volunteers Brett, Dennis, Gary, Ian, James, Mike, Paul, Rob, Stan and Steve  under the supervision of Dave Lewis, undertook the following restoration work ….

 

FOREDECK
IMG_8350.jpeg
Handrail 
Mike, Rob & Stan applied black marine sealant between deck and base
of all 6 handrail supports before retightening securing bolts . . .
Mike removed the masking tape from around each of the supports . . .
 

 

WHEELHOUSE
 
Rob removed the layer of t&g planks on top which are not be replaced,
but the t&g planks below will be restored
Rob scraped back the layers of paint . . .
Mike carefully removed screws in need of replacement
on the wheelhouse windscreen frames . . .
 attended to replacement stainless steel screws and silicon bronze nails,
ensuring countersinking of each. . .
….. Rob removed timber cover strip between wheelhouse shelf and cabin top …..

Having removed the timber cover strip, Stan scraped back the timber                                 in preparation for replacement cover strip  . . .

Mike and Stan continued with removing gal screws and replacing with brass screws . . .

Mike continued with replacement ss screws and silicon bronze nails on the cabin’s interior,

 Stan completed the template for the replacement cover strip for the exterior where cabin meets front deck

 

Mike continued with delicate removal of fasteners in need of replacementIMG_9395.jpeg

and of internal timber window surrounds …

IMG_9418.jpeg

Mike & Stan continued with removal of timber window trims (16 down – 7 to go) in need of replacement

. . . and made markings for replacement fullwidth trim piece.

Dave & Mike worked on getting the angles right for each of the corners for the first of 6 wheelhouse window internal surround pieces ..

Stan continued with shaping the timber strip to run along the underside of the front of the wheelhouse….

Mike & Rob  combined efforts to sand and prepare the surrounds where 150-odd  silicon-bronze or copper fasteners are now in place

to mix the epoxy filler

Frame-10-10-2017-06-20-44.jpeg

and to apply same to match the wheelhouse’s timber surfaces

Mike & Rob continued with the scraping and sanding of the infill covering of the new fasteners, as well as preparing the timber surfaces for later painting

Mike completed measurement and cutting of the dressed maple quad for the portside window

and made a start on the s’board window quad . .

IMG_9995.jpeg
Mike prepared 2 lengths,

IMG_0060.jpeg

then glued & screwed these to the sboard & port sides of the top of the wheelhouse . .

. . . at a later date a wooden handrail will be attached to these timbers utilising recently donated brass fittings.

CREST nameplate

In July, the CREST nameplate on the starboard side of the wheelhouse was removed and placed for safekeeping in the storeroom

 

Paint work

In mid-July, Rob started brushing blue gloss oil paint as overcoat on the faces of interior timbers – planks, stringers and ribs . . .

During August, after hand sanding the first coat, Rob completed the second overcoat . .

 

COMPRESSION POST

Because the Crest has a deck-stepped mast, a support, known as a compression post, is needed to fit the underside of the deck below the mast-step and the keel timber.  
Stan has been working his magic on a shaping a length of oregon which will become the compression post, which will be octagonal in cross section and marine varnished to show its grains..

1911 penny

Earlier Stan had put out the call for a 1911 penny and in December Barry brought one in

IMG_0533.jpeg

The penny will be secreted at the base of Crest’s compression post when the time comes ..

1951 pennys

In late August, Paul removed 3 copper fasteners which had been used on the midships beam shelf starboard side and after cleaning the paint off the washers, 2 were revealed to be 1951 pennys.

IMG_9197.jpeg

Midship BRACE

In September, it was decided that the midship brace needed to be removed and replaced. The existing brace, a galvanised iron bolt was replaced with 2 stainless steel rods which will be threaded and joined with a ss turnbuckle tensioner below deck.

2 photos below shows the gal bolt alongside the ss rods & tensioner . .

PORTHOLES

In August, Stan took on the job of chasing up replacement glass for the 2 brass portholes before they are re-attached to the hull  ..

IMG_9086 (1) IMG_9089

CHAIN PLATES

Also in August, Gary made up new copper bolts, complete with head and thread, and then secured the refurbished chainplates to the hull…

and at the end of August secured the bow’s chain plate . . IMG_9301.jpeg

BREASTHOOKs

A breasthook has the function of securing the hull’s port and s’board sides where they meet at the bow and is placed across the stem.  The Crest has 2 breasthooks – one, of timber, at the level of the first stringer, and the second, of metal, at the second stringer.

In December, Ian shaped the spotted-gum timber needed to hold the hull’s refurbished galvanised iron breasthook when it is secured back in place ..

 

 

KEEL-RIB infills

In the space between where each set of ribs meet on the keel, an infill is required.       One such space can be seen in the photo below.

fullsizeoutput_821   There are 40 pieces needed and are to be made from spotted gum timber.

In August, Gary, having worked out the measurements,IMG_9131.jpeg

made a start on making the pieces using a 6metre length of spotted gum which had been milled some 12 months previously.

The sequence of photos below show the steps gone through . .

. . the timber length is marked up ….

…..cut length-wise on the portable bench saw . .

IMG_9153.jpeg

. . . put through the thicknesser . . .

IMG_9156.jpeg

then, up at the Museum’s workshop shed, cut precisely lengthwise vertically into two pieces,

IMG_9159.jpeg

IMG_9166.jpeg

then, after thicknessing to 16mm, marked out,

IMG_9193

. . and cut into the sections as required . .

 Each infill must be precisely fashioned for where it goes . .

IMG_9237

and then treated in marine preservative . . .

. . . and secured . . .IMG_9635

 

PLANKS

From July onwards, Gary took on the job of measuring up and making the replacement planks. The number of planks to be replaced at this stage is  4 on each side of the keel – a total of 8.  Each had to be made from Fijian Kauri and scarfing (overlapping) is required.

Before continuing with the replacement planks, Gary shaped a short length of softwood (1st photo) to make the replacement stopwater* which is a dowel driven into the hole drilled in the joint of the keel and the deadwood (which are both hardwood) at the level of the rabbet line.  (2nd and 3rd photos) Because this is below water line, the softwood swells when wet and helps to ensure no seepage between the timbers at that joint.

*Stopwaters are also known as trunells (an abbreviation of tree nail) and are most commonly used to fasten planks to ribs and/or frames.

 

 

For the replacement portside garboard plank, Gary shaped the veneer template then matched it to the Kauri pine length before cutting to shape

Gary continued with cutting, planing and shaping the 2 lengths of Kauri which will make up the new garboard,

 

and started on the 5.7metre long veneer template for the 4th plank on the s’board

 

and in August, Gary checked the veneer template for the 4th plank on s’board,

before removing and laying it on 25mm thick Kauri,

IMG_9005

then, after marking up the key positions with ruler and compasses along its length,

lightly hammered in nails at those positions before laying fairing batons against the nails,

and drawing profile lines top and bottom,  before cutting with electric jigsaw or rotary saw

Once cut, Gary then put the plank through the thicknesser to reduce to 20mm.

In August, Paul took on sanding back the faces of new planks which are sitting slightly proud of existing . . .

ensuring fasteners (brass screws & copper nails) were countersunk on the new planks  . .

. .  to allow for sanding of the new timber. . .

IMG_9134.jpeg

In October, Paul started preparing a short section on the underside of the keel just in front of the rudder post where an infill piece is required to match the face of adjacent planks. The tapering infill piece will be glued and secured.

Also in October, Gary made up the starboard garboard which will be in 2 sections with scarfing (overlapping) as needed …

first putting the kauri through the thicknesser ..

temporarily securing flexible baton to draw the edge lines . .

then cutting the length just outside the edge line . .

IMG_9700.jpeg                        By mid October, Gary had completed the shaping and scarfing                          of the 2 lengths for the starboard garboard

IMG_9867.jpeg

RABBET

In October, work on setting the keel’s rabbet continued . .

On the portside amidship, Gary chamfered edges of the timber infill sections

after which 3part filler was mixed and applied to nooks and crannies between infills and keel timber . .

IMG_0001.jpeg

 . . . and then a 3metre veneer length cut to which a slightly longer pine baton was air-gun stapled . .

… and then shiny-brown packing tape applied to the veneer’s surface along the length . .

IMG_9996.jpeg

. .  before clamping the veneer, tape side up, against the ribs.

The clamping enables the filler to be held where most needed while it sets.

Once set and dried, the  filler is cleaned and sanded . .

Gary continued these steps for the rabbets on both sides of the keel until the end of the year

The reason for setting the rabbets correctly is to ensure that the garboard planks will fit flush with the keel timber.

STERNPOST

In October, Paul started scraping down and cleaning up the the sternpost’s bearing adaptor piece . . .  which had been removed sometime ago.

IMG_0091.jpeg

IMG_0184.jpeg

This piece attaches to the aft of the sternpost on the underside of the keel, and has the propellor shaft through it. 

IMG_0188.jpeg

IMG_0228.jpeg

That part of the original sternpost above the keel line was previously removed.  
Brett spent sometime getting the shaping and positioning of its replacement piece, 

IMG_0054.jpeg

so that it will key-in correctly with the extant sternpost . .

IMG_0074.jpeg

IMG_0079.jpeg

IMG_0126.jpeg

Dave and Brett  finalised the position and the setting of the replacement stern post.

IMG_0164.jpeg

IMG_0163.jpeg

 

AFT BULKHEAD

Brett and Dave worked on getting dimensions and measurements of the replacement aft bulkhead.

Photo below shows the removed bulkhead and bollards (corner posts).

IMG_0227.jpeg

A horizontal reference line between  coamings was established,

IMG_0233.jpeg

IMG_0235.jpegthen the distance between bulkhead and the rudder post measured

IMG_0269.jpeg

and Brett was able to give a thumbs-up for the dimensions and measurements … IMG_0288.jpeg

Later positioning with the coamings and rudder post were confirmed

and a start on making the replacement bulkhead from maple got underway . .

The first section to be made is the splashboard . .

which includes shaping of the bollards

Rudder post, Stern post, horn timbers, and washbox

These timbers were a priority in the second half of the year.

Running either side of, and attached to, the rudder post and the stern post are pieces known as horn timbers which function to support the overhang of the stern. And behind the rudder post is the wash box.

From early July, Brett, Paul and Dave set about preparing these pieces .

Brett and Paul, applying two-part filler and black marine sealant as needed, manoeuvred, propped and clamped  the horn timbers, rudder post, and washbox into position, and when all aligned tightened the clamps . .

 

When the filler and the glue had dried, clamps and props were removed and brass screws were turned and  copper nails hammered as needed . .

   Brett and Paul continued with sealing the horn timbers, rudder post and wash box … this required mixing 3 part filler (resin:hardener:filler powder – 5:1:as needed) troweled into spaces as required. Brett also troweled filler onto those sections of the cockpits coamings previously scraped back and preserved.

 

COAMINGs

Repair and replacement of portside coaming first ..

 

   Then, in October, the s’board coaming  ….

 

FLOORs

Work on replacing all the floors continued ….. at the beginning of July, Barry, Ian and Dave checked on Ian’s templates for heights and alignments for each of first 6 floors

After which  cutting, shaping, drilling, thicknessing continued …

By December, Barry, Ian and Stan were able to give the thumbs up to the shaping and positioning of 5 of the floors ….

 

Engine beds and bearers

  Engine beds sit on top of the floors and bearers sit on top of the beds.

The  photo below show the bearers and beds before removal in mid-2015.

IMG_2933

In mid-2017 the decision was made to make replacement beds and bearers, and as with the floors to be of hardwood.

Over the ensuing weeks, Ian, Barry and Dave shaped, milled and cut 2 lengths to make up two new bearers.

 

ENGINE

LISTER 3 cylinder diesel

Having got the Lister running in June, Steve continued with sorting

out a recalcitrant fuel pump and injector….

IMG_8473.jpeg

after which getting the governor to do what it should …

IMG_8914.jpeg

and in September having to sort out a minor leakage in 1 cylinder’s fuel line

Frame-05-09-2017-05-16-16.jpeg

and in October successfully attached the flywheel drive gear

IMG_9739.jpeg

tapped (rethreaded) 8 bolt holes on the flywheel drive . .

IMG_9872.jpeg

and worked on the throttle  . .

IMG_9937.jpeg

In November, the governor spring setting needed attention . .

IMG_0248.jpeg

as did how the aft shaft stuffing box and its interface with the sternpost adaptor piece which Paul was working on would be best achieved…

IMG_0240.jpeg

IMG_0232.jpeg

IMG_0228.jpeg

At the end of November, Steve had the engine running sweetly, its timing and the refurbished governor spring doing what they should …

and so another small milestone … the engine number ID plate attached.
