Repairing bottom planking 1

Now that the main upper structure of Nanw was complete i.e. Frames, stringers and inwale all fastened she was sufficiently stiff to be turned over and put on trestles - she is quite heavy and it took three of us to turn her over safely.
The bottom planking has two areas of damage: A split in the second plank port side for about 4ft amidships and some stoving in on the starboard side - probably caused by clumsy handling on a trailer. Now, professionals would probably insist on replacing all the strakes full length but as this is a 'low value' boat and timber and copper is expensive, I intend to adopt a method I have used successfully in the past and scarf a new section in to each plank, staggering the scarfs.
Firstly, all the remaining fastenings along both lands were cut and driven out to beyond the damaged section and a line marked across chosen to miss the frames. Then a line of small holes were drilled and the keyhole saw used to cut across the plank. A chisel chopped the timber in way of the lands, inside and out, and the section was teased out. Scarfs were marked for a length of 3" on each end of good plank (a ratio of about 7 times plank thickness). Cutting them is a time consuming business in the boat, mainly using a 1" chisel. A small wedge opens the land to allow the scarf to be cut under the land.

Inwales fitted and fastened

The new inwales were cut from some close-grained Douglas Fir and had some gentle tapering to fit snugly behind the existing breasthook and quarter knees that had been left in place. A beading was planed on the lower edge of the timber as had been done on the stringer below it. The inside face of the timber was given a couple of coats of wood stain/preserver and then clamped firmly in place and fastened all round starting at the stem and working aft. Once fastened through all the timber heads the  Jack Nichols was glued in place each side of the stem and the long copper nails through the breasthook, thwart knees and quarters were driven and fastened.

Fitting thwarts and preparing the inwale

After fitting and fastening new stringers the mid ships and forward thwarts were re-fitted and a new after thwart made from hardwood and given a beaded edge to match the other two. The thwart knees are basic bent angle brackets but neatly made and were galvanised.  Ideally they should have been re-dipped but I gave them a good clean up and a few coats of 'galvafroid'. These were bolted back in after priming the timber edges using the original screws which are stainless M8 countersink - a clue that this little boat is not as old as she looks.
I intend to fit an inwale to the insides of the full-height timbers and this is a change to her original construction. In preparation for this I am fitting sections of timber between the ribs in way of the thwarts, the rowlock positions and at the vessel's ends.

Fitting stringers and thwarts

Now that all the new ribs/timbers are fitted and fastened I turned my attention to fitting new stringers (sometimes called 'risers') at thwart level. The existing thwarts were bolted back into place with their galvanised iron knees and the new stringers sprung and wedged into place and then fastened trying to pick up existing fastening holes where possible. The after thwart was a non-original and over thick piece of softwood and some new Iroko is on order to make a new one to match the two other hardwood items.

New stringers replaced originals that were in various short sections.

A Redwing undergoing a re-fit

A Redwing sailing friend has been busy locally doing a major refit on a 1952 Dann-built Redwing, 'Pegasus' that had been laid up in his barn for many, many years after he rescued her from deterioration outdoors after previous owners had lost interest. 'Pegasus' was in need of a new deck, new ribs, various other minor repairs and a few updates like the retrofitting of Centreplate case stiffeners and provision of transom ports.
Typical of old Redwings is the failure of glue joints in the deck beams, carlings and other deck/framing joints and here 'Pegasus' has been meticulously re-glued. Her owner is a professional bespoke wooden furniture maker and the quality of his workmanship is top-notch.  He was at the re-ribbing stage here and I have been lending a hand to fasten new frames.  Ash has been used here but being a bit dry before steaming necessitated a prolonged soaking in the pond before going into the steamer.

New ribs going in - doing this without the deck makes the job a whole lot easier!

She needs a complete strip and re-varnish job.

Timber fastening progressing

We have now got all the new frames/ribs/timbers fastened in place apart from the timber heads which will be done when the new inwales are worked into the boat. When the new timber has had a chance to completely dry they will be give a soaking with wood preservative prior to painting to (hopefully) prolong their life this time.

New timbers fastened. The missing ones are where there are still other repairs required to the skin planking.

All new timbers in place

Finally I have steamed and bent in all the replacement timbers into Nanw. All the thwarts were removed and replaced with spalls to hold the sides together and, in the bow, to hold the sides apart as she wants to close in due to the pressure from the new planks and battens. The ribs in the bow were more difficult to fit than expected, due to quite a lot of twist needed to make them lie against the lands and they may have benefited from being 'hot-nailed' in place as soon as they were bent, to make them stay put.
I surprised myself by not breaking any of the new ribs in the process of fitting them. Therefore about 8 or so left over which I hope to use in another boat very soon before they dry out.
There is a bit of nailing up still to be done before the temporary G-clamps can be removed finally. A really worthwhile job was stripping, sanding and priming the inside of the hull as the old ribs were torn out. Once the job is all painted the boat will look like a new one - inside at least!

Priming the fore peak. She was closing in without the foreward thwart.

All new timbers finally fitted - just need fastening now.
