Decided to make the upper works of Styrene in the hope it would better replicate steel plating.

The styrene superstructure looks realistic as steel Baldrick A bit of Humbrol paint mixed with a little talc stippled here and there to suggest painted over rust would add a little weathering should you want to, but as it is, it looks crisp and tidy with less of the effort required to make wood smooth with fillers etc etc.

Hi ballstanksian , thanks.   I would like to introduce a bit of weathering, think I will try on a few trial strips to see how I manage. I have been thinking about the colours scheme. Current photographs of Cervia show her topsides in a farmyard brown livery which I am not sold on. I have found one photograph her her during her working life in a red (orangey) brown which I have obtained a can of spray pant to a similar colour. It may be that the colour render of the old colour print is not true to the original hue but it is without doubt more colourful.

Cervia had a casing colour of Dark teak gloss, all of her working life,  the funnel red is best replicated using Humbrol No 100 Matt red and then gloss varnishing it, as I have not yet found a colour to match at all as we used to mix it using red lead powder and linseed oil. Her decks where they were steel was red oxide gloss and the boot topping at the bow was Emerald green, and the windlass side plates were also green as was the capstan casing over the steam engine and gears.

hinges look a tad chunky, wonder if I need to file them down a bit.

Twas the bendy curvature of the front of the deckhouse that took most time . Perhaps I can pick up a bit of speed on the rest (at least till I get to the smoke stack )

Goose neck vents for the fuel tanks, how to scratch them ?   thought I would try this way ;   First a piece of 4mm copper tube and make two 9/10 cuts 1/2mm apart and bend to give the neck shape.





 Then mould some Super Sculpey to rough shape over the end and give it 15 min at 130C in the oven.







.File and emery paper it to shape, the Sculpy is quite easy to work.







finished and painted , at present just pushed into a drilled hole in the tank top . Look reasonable to scale, from photographs the Cervia vents I would assist be about 6-8" dia.

 Jumping around a bit I started to look at the lifeboat davits. Not a lot of info on the plans except they are Welin Mclaughlin and not much on the web, have done a hand drawn sketch from photo's  on the Cervia site to give me some templates to work to.  I intend to make them from styrene with a bit of discreet reinforcement to stop the arms twisting. The drawing is showing the tops of the arms a bit too thin, I will need to beef this up when building.

Baldric,


About 40 years ago I started S.T.Cervia from Vic Smeads Drawing at 1/4" -ft as a free plan, I progressed as far as getting the bulkheads and frames made and decided that it was too small so redrew it to 3/8" -ft which turned out the best idea as it is now powered by a Scotch boiler and a Stuart D10.


Like you I found it difficult to get any info on the Davit but was fortunate enough to have a cousin who was the oiler on the Waverley  ( John Lees )and when she was laid up in Glasgow for the winter I was able to take some sketches of the Welin Mclaughlan davit fitted
 to her.
I have had a search for my sketches but after 2- house moves , no luck but here are 2- pics of the davit that I made using plastic card and they are still strongly fixed after all the years , possibly need re painting.
I hope that they are of some help to you.


George.

Thanks both for your valuable input , I can see I have to amend my drawing , especially in the area of the stool for the restraining arm.  In this respect I assume the rod or arm is telescopic so that it can extend to allow the davit to swing forward to the lifeboat deployment position. I have been looking at this drawing and note the crank handle which would seem to be for releasing the adjacent locking bolt allowing gravity to take over.
