Probably what ended up being the most difficult part of the build was fitting the stern tube. Using a ready built model with the aft end enclosed it was never going to be easy as you basically had no idea what you were drilling into. I tried drilling from the aft end and ended up coming out in entirely the wrong place so I tried drilling from inside the hull and again came out in entirely the wrong place. The only thing for it was to remove the aft decking:

That way I could at least see what I was up against and then, hopefully drill partway in from both sides and finish off with a long tapered reamer and files. Removing the deck revealed an odd assortment of keel and stern frame, which had obviously pushed the drill off line. I hacked out a lot of the wood with chisels and knives to free up the space, drilled from both sides exactly where I wanted the tube to sit and fitted the stern tube in place:

At this point I also removed a section of the stern frame to allow the propeller to sit back in the hull:

A similar recess was also cut into the forward part of the rudder giving the 40mm brass propeller clearance all around at all rudder angles:

When the tube eventually sat exactly where I wanted it with the end lining up with the engine shaft and because I had removed quite a bit of the strength I decided to fill in a large part of the space with poured resin. This was also painted internally up the sides of the hull in a number of separate pours to seal this compartment completely and give it some of the strength back before making a replacement deck, out of the same doll’s house flooring as I’d used for the side boxes, and fitting it to new runners glued to the inside of the hull. I also put the steering servo in place at this point:

I must admit to being pleasantly surprised that the spare shaft and tube I had was a perfect length for the job so that was another item of stash effectively put to good use. I even had the pouring resin on the shelf so quite a few items that has been sat on the shelf for some time were finally being put to good use.
Moving to the outside of the hull the first job was to strip off all the evidence that this was a model of a Titanic lifeboat so the company flag, the name plates and the rope grab handles were all removed and the holes wiped with Tamiya filler. The rowlocks were also removed and the holes filled and, when dry all the filler was rubbed down:

In the knowledge that I had discovered the hull was not sound when I did the initial stability test I knew I had to do a complete sealing job. I was very loathe to either take anything apart or even to strip back to bare wood so a little research on line revealed a couple of products that would help with the job. The first was Captain Tolley’s Creeping Crack Cure, which I had never heard of before. It is basically a sealant that has a viscosity lower than water to it seeps into every little crack and gap by capillary action then sets to form a seal. I ran a bead of the fluid into every joint on the outside of the hull, let it dry completely and then went over the hull a second time:

The options then were to either paint the outside with some more pouring resin, which can be a little tricky on such a large surface as it sets so quickly, or a coat of Eze-Kote. This is supposed to be a water based alternative to pouring resin and, while I have seen some arguments that it is not quite as strong as resin based products, I didn’t need the strength in this case I was looking for the sealing properties:

It is a lot more convenient to use and apply and it doesn’t cost you a paintbrush every time you use it so I went for three coats of EZE-Kote all over the external surfaces of the hull:

When the Eze-Kote had set properly and before I applied any paint I did another test in the bath and was pleased to see no leakage whatsoever into the hull. After that the upper hull was given two coats of Humbrol Gloss Ivory:

, and the undersides a coat of Crimson Lake Coach Enamel from Craftmaster:

The top of the bulwarks was finished off with a Humbrol Matt medium grey to frame the white neatly:
