Over the last month, restoration work has included …

TIMBER and HULL WORK

RIBS (correctly known as STATIONS)

Five more replacement ribs have gone in – the technique for one of these was a first for the restoration.

In-situ laminating

Just forward of the stern-post, this rib has a sharper curve up from the keel to follow before it continues to the gunwale. It was decided, rather than using a single 16mm thick length, that steaming and bending three 5mm thick lengths and gluing as we went would be more appropriate – a form of “in-situ” laminating.

The  3 photos below show the three lengths being lined up and checked.

Once the first 5mm thick length was in place, glue was applied to its surface before the second length was positioned and held, and the same again for the third length.

Wedges, rib-jig and leg-pressure were used to keep laminates in position while copper nailing was done. Next 6 photos.

Special mentions

Rib-steaming assisted greatly by Brett’s modified-gas-bottle hot-water supply for the steaming box and rib positioning was greatly assisted by Stan’s ‘rib-jig’.

Dave’s rib-shaper-jig was put into use last week.

HULL PLANKS

The damaged ends of adjoining planks were removed and a piece of Fijian kauri is being shaped as a replacement.

RIB removal and replacement.

In this section, a more detailed explanation of how the rib removal and replacement is given.

Removal of timbers is done so in a manner which creates as little damage as possible to the timbers to which they are attached.

Laid on top of the ribs are the stringers which run the full length of the hull.

The stringers are removed as needed.

    IMG_4743

The damaged ribs are removed in a sequence which creates as little stress as possible, eg. adjacent damaged ribs are not removed at the same time.

IMG_4726      IMG_3931

After the copper nails are removed, each nail hole is filled with 2 part epoxy.

IMG_3945   IMG_3938

Once dried, both external and internal surfaces are sanded.

IMG_3896    IMG_3776

The replacement ribs have been milled, cut, and planed previously.

They are steamed for up to 45minutes to allow for bending to follow the profile of the hull.

The first to be replaced were 3 ‘sister’ or ‘twinning’ ribs.    IMG_3841

These are laid next to the full ribs (which run gunnel to gunnel) and are needed for hull rigidity below the engine bearers.

Once slid and held in place, 6cm long copper nails are driven from the underside of the plank while pressure, using body weight and/or a metal stopper is needed to keep timbers flush.

IMG_3899    IMG_3831

When all nails are in, they are cut to about 2cm length and then bent and hammered over into the timber.

This last action requires a weight against each nail head on the other side of the plank.

#A big thank you from the Cresters to ‘Wandy Bus & Autos’ on the Princess Highway at Wandandian where Wayne applied the impulse driver to loosen the flywheel retaining nut.

The Museum acknowledges the sponsorship of the IMB Community Bank, the Bendigo Bank Community Fund and the Australian National Maritime Museum.

We also are grateful to the TE Davis Sawmill at Wandandian and Ison and Co Hardware at Nowra for their contributions towards this project.

CRESToration continues

The Museum has received funding from the Bendigo Bank Community Fund and previously from the IMB Bank.

This funding allows the dedicated volunteers to continue under local boat builder Dave Lewis’ instruction and supervision to take the complete the restoration.

The funding includes expenses for more materials, some tools and the acquisition of a replacement 3cylinder Lister diesel engine.

The documentation of the restoration, in words and images, will also continue in the form of regular updates on this blog site.

There are currently up to 8 volunteers putting in the hard yards, not to mention tender loving care, mostly on Tuesdays, to ensure that CREST will be restored to her former glory.

The attached photo taken by previous owner Max McRae shows CREST at anchor in 1983.
