RFA Gold Ranger
« on: November 01, 2011, 10:45:58 am »

RFA “Gold Ranger”. The real ship and the model.
This could turn out a rather pleasant way of getting through a bit of the winter period….at least in the bit of the world that I live in.
About 20 years ago I’d recently completed the s.s “Hunan” and was casting around for another ship to model. By now I was used to building at 1:48 scale, but that imposed a definite size limit. I reckoned that an original should be no more than 340ft long, as that would result in a model that fitted nicely into my trailer. I really would have loved to build something like a Blue Funnel or a similar sort of ship, but heaving a 12ft long model around didn’t bear thinking about. I seriously considered an LSL of the “Sir Tristram” class. That would have been nice as I knew those ships inside out. I could even get it on to the trailer if I left the rear gate open. But the “girth” defeated me. A pity really. I’d never built a “Grey Funnel” model before and felt that my growing “fleet” really ought to have at least one. But definitely not a warship. So the old “Ranger” class came to mind.
Funny looking little things they were….built around 1941 – 1942 they were the first re-fuelling ships designed by the Admiralty since 1914. And it shows. Who but the Corp(se) of Naval Constructors would come up with a ship designed to refuel anything from battleships to minesweepers in any part of the world that could only carry 3,000 tons of “cargo” and had a loaded freeboard of about 3 ft.
But 6 of these things were ordered. Some from Belfast and some from Dundee. But even these were a bit long for me (at 355 ft), until I found out that Gold Ranger was for some reason 10ft shorter than all the others. So that was it.  The ones that weren’t sunk, wrecked on rocks or otherwise scrapped soldiered on well into the 1970s when the “Rover” class was introduced. I think the “Black” was the last to go.
Interesting to note that the names all came from types of anglers fishing flies, as the various ships crests show. I’ll see if I can dig one out…..sometime.

Sorry about the gap....the little window I have to type in won't let me do the whole thing in one go!
1.      This was “Black” during WW2…..before the advent of abeam refuelling (a method copied from the Germans after the Altmark was captured.
                                                 
2.   This one is interesting mainly because it shows the false funnel and pretend superstructure on the focslehead…funnel partly hidden by the foremast.
Another “quirk” these ships had was the asymmetric positioning of the funnel and masts. The funnel was about 8ft to port of the centre line, the mainmast was on the centre line and the foremast was well to starboard of centre. This was another ruse to confuse an attacking aircraft when the common attack mode was to line up the masts and so on  before dropping their weaponry.
       
   3.     The next 2 are of the “Gold” during the period of the Korean war…although the one taken in Capetown is a long way from Korea.
                                         
The last 2 pics show the ship as fitted with both a beam refuelling derrick and a RAS winch deck fitted.
See what I mean about the freeboard? I don’t think I’d like to be caught in a blue ocean storm aboard her.
Now all I have to do is hope that I can get this lot from here on to the Mayhem site!
To be continued.

It may seem at first as if I’m breaking all the conventional ways of doing this…but I’m not, as you’ll see. The next 4 pics are of the completed model (obviously), but after this I’ll get back to a more conventional layout.
I originally thought I’d just do a quick run-down on the bit of re-furbishment the model needs after its few years languishing in the head office of the RFA Association. There’s a good chance that this office will be relocated to Portsmouth in the near future, and I certainly didn’t want the model to be relocated with the rest of the organisation. The office at present is in a small town called Bellingham, more or less smack in the middle of the wilds of Northumberland. Not really an odd place for it as when the RFAA was first founded one of the founders, and first Chairman, lived in the area. But the organisation has grown massively over the years and the majority of the members seem to live at the bottom end of the UK. So it’s a logical move really. The model was taken up to Bellingham for 2 reasons. One was that I was invited to have it up there “on loan”, I was more than happy to do this as reason 2 was that I had nowhere to keep it “at home” if I wanted to build another large model. Especially as I was contemplating building “Baroda” at the time. Now I have the space…so I brought her home. Apart from being a bit dusty and a few bits of rigging adrift (and a couple of the Lewis guns gone walkabout) the only real damage was caused by me. Putting the ting into the trailer I got the positioning wrong and slapped the stern with the trailer tailgate…causing some damage to the stern stanchions and rails. Fixable. But the dusting will take some time.
When I got the removable full length top part into the workshop I thought it would be a good opportunity to show its construction an some of the detail work. For some reason I didn’t take any photos during her build. The hull is of GRP and basically followed my usual practice as shown in pics of some of my earlier missives to this forum. So I’ll ignore the hull.
After this post I’ll concentrate on the making of the decks and superstructure insofar as I can remember doing it…..memory is an “age thing” you know!
Now you can see why this appeared to be being done ass-backwards!

Having seen this model in the flesh so to speak, I can say it is beautifully made and a credit to Bryan

To continue:
Fitting the main deck. Due to the size of the model (7ft long), it was obviously going to take a lot of spaced ballast (I reckoned the AUW to be in the region of 110lb).
This ballast…and the batteries…would have to be placed in the empty hull after the hull was afloat. So access to the inside of the hull was a necessity, so a full length removable deck was required. I had some experience with this when I built “Hunan”, the big difference with this one was going to be the drop of the main deck in relation to the focsle and after end superstructure. Much head scratching and cracking of the Laughing Cavalier (again).
The main problem was getting the line of the deck to be both rigid and follow the fairly pronounced sheer …the centre part is pretty flat, but the focsle rises quite steeply. So some sort of shaped “strongback” was needed to fit the sheerline. I’d realised that weight wasn’t going to be any problem as far as the model was concerned, although carting it about could be a handful…but that was something to be solved sometime in the future.
     I started off by cutting a sheet of 1/8” ply to fit (longitudinally precise, but over wide in the beam) in the maindeck section. The ply had to be laid with the main grain running transversely as there is a slight amount of sheer as was proved when I had to weigh it down so the ply fitted snugly on the hull sides (hence the reason for cutting a bit overwide). A card template was then cut and transferred to the relevant part of the full length strongback, bandsawed out and screwed to the ply. So far so good. This “main spar” is the lowest one shown in the 1st 2 pics.(the lowest unpainted one). This was OK for the centre section but left the end bits pretty wobbly. So then I had to make and fit 2 false bulkheads at the break of the focsle and stern section. Easy enough. Then a rather “fiddly” bit…getting the main spar to fit within the hull. The rear part had to be made a bit shorter than I wanted it to be because of the hull shape , but the forward bit was eventually cut to fit and the lump of timber that looks like a false bow (pic 2) fitted. Overlength, to allow for further trimming. A stiffish card template was made of the focsle shape with a slot cut out of it to slip over the protruding upright bit, which could then be trimmed to length, and a secondary strongback cut and fitted between the upright and the false b’hd. Same procedure at the back end with some variations. Further 1/8” ply “underdeck pieces were cut and fitted….and, lo and behold, I had a sturdy platform to work on.  Of course, being only supported down the centre line made it all a bit flexible across the beam….and it wouldn’t stand up by itself, so more beams were fitted spreading out from the narrowest parts of the hull to the false b’hds at the ends, and others fitted along the sides of the maindeck (the grey ones). The whole caboodle being notched to fit over the permanent hull b’hds which lets the whole deck sort of clunk into place when fitted on to the hull….and it doesn’t fall over when “free-standing”.
So that’s my way of fitting a removeable deck.
Now the more interesting bits can be made.

This photo is a bit of a one-off .
Apart from the timber bracing at the sharp end, it’s really to show the offset from the centre line of the Funnel and foremast.
I’ve seen a similar arrangement on the old “Ocean” class WW2 ships, but that was confined to the offset between Samson posts or tall vents….this time to give a submarine a false idea of the ships heading.

These 2 photos are the last of the general “record” picture. Future ones will be more to do with details. All the photos both previous and future were taken before any cleaning and repair work was done (not that I’ve got around to starting that yet).
If you compare the maindeck photo here with the last 2 B&W ones, you’ll see what a difference it made to the ship when the abeam rig and RAS deck was fitted. To my mind it took away some of the (minimal) charm the ship originally had. Yes, the ships efficiency was improved, but not the looks. That’s why I decided to build the model as it would have appeared soon after the end of WW2. The grey paint removed, the bridge freed of the ugly splinter cushions and all the rest of the “not needed at this time” stuff….but the guns remained for a few years….just in case….
     Although this class of ship was denominated as  “Fleet Attendant Tanker”, a term I’m not familiar with (!),  the ships were deployed with the Arctic convoys to Russia. That must really have been arduous. I just can’t imagine doing a stern RAS from on board a Destroyer in winter conditions “up there”.
As a bit of an aside, the RFA also built another class of ship with an even lower freeboard….the “Eddy” class. From pictures I’ve seen of those, they closely followed the design of some of Frank Everards ships of the period.

Right, let’s get to the nitty-gritty of the model.
I’ll start of with the focsle head and sort of make my way aft, probably with some deviations on the way.
Firstly, the big hole in the deck just aft of the gun housing/mounting. This is normally filled with a cargo hatch. The general sort of thing you’ll find on any merchant cargo ship of the era. On the model this is a removable feature and the empty hole acts as the forward deck lifting handle. When I lifted the deck out of the trailer the other day I forgot to replace it. But now it’s off, notice the gap between the underdeck and the visible one. This shows the amount of deck camber at that point. Being so far forward, the camber is a lot less than it is amidships.
The deck itself is (was) steel plated. Litho plate on the model. As with all plated decks that have overlapping plates, the outboard strakes are laid first, starting with the plate that’s at the lowest point of the ships sheer. That way all subsequent plates have the visible end joint facing the “low” point. So water drains that way. Similarly, the fore and aft strakes have their visible edges facing outboard…apart from the centre strake that shows visible edges on both sides. Small (but visible) rivet marks are on the visible edges…emulating countersunk rivets, not raised ones…you don’t want the deck boy to break an ankle on a raised one…there are plenty of other places for him to do that…not least on one of the plethora of eye bolts scattered around.
All the litho plate is simply stuck down with double sided tape and none of the plates have come unstuck since the model was built. They even survived a rather eventful foundering of the model due to my inattention. Took 4 of us to heave it out of the water that was deep enough to submerge the whole model to more than bridge height.
We just drained the water out and let it dry in it’s own time. Nothing came loose and everything still worked afterwards. In fact, much of the grime on the decks is remnants of that day about 8 years ago. Time for a clean.
The winch and windlass are both scratchbuilt. Mainly out of Plasticard and various thicknesses of Perspex. I love using Perspex. Takes a lovely finish and is easy to machine. And cheap when you can get free offcuts. The thinner of the “perspexes” is the thin sort that is used for secondary DIY double glazing (one trade name is “Glodex”), it’s about 1/8” thick. Some of the visible gear wheels (Perspex again) I had to make, but many of the smaller ones can be salvaged from such things as defunct geared electric motors or a pack of a servo repair kit. The structural stuff is generally just plasticard with plasticard fittings (doors, hinges and so on).
All the stanchions are by James Lane…one of the many sizes he produces. Which reminds me that I need to straighten some of them.
As I build (generally) at 1:48, I can use the same bitts. Seeing as I only ever made one mould for these things, that’s come in handy. The actual bitts are made of the same pink stuff that false teeth palates are made from..as are some other small fittings.
The decks are painted a shade darker than the hull/superstructure…makes a nice contrast.
The round black thingy nestling on the stbd side of the gun housing is a wickerwork anchor ball (2’ dia in real life). Amazing what the Dolls House fraternity use….like the wickerwork baskets on my trawler. But I digress. Time to add a photo before there are too many words.

Just a few odds and ends to tidy up before I move down on to the main deck. The “tank deck” I suppose you could call it.
If you gaze steadily at the foremast, you’ll see that the foremast nav. light is way out to port on the end of a half yard. This is so the actual light is on the ships centreline. The offset mast was meant to confuse the Germans, not our allies.
As this build etc carries on, it may be observed that the winch on the focsle head is the only winch aboard (apart from one down aft).
Look at this from a practical point of view. At first it seems to verge on the edge of stupidity. But it isn’t. For a start, the tank deck is more likely to be awash than the focsle head. That’s one reason. Actually, the only one I can think of. But the seamen on deck must have cursed the layout in calm weather. There are so many jobs/evolutions to be carried out that entail the use of wires and a winch. Having only one winch, usually a long way from where the work needs to be done, means the use of a multitude of snatch blocks and long “bull ropes”/wires. Leg breakers.
Note the guides for the hawse pipe covers. For convenience, I’ve stowed the actual covers inside the gun housing. (says he, lying through his teeth…I forgot to make them).
Then there are the 2 hydroplanes. The real ship had a large “hole” right at the bottom of the forefoot. A wire would be reeved through it and attached to the nose of each hydroplane. The hydroplanes flaps and so on would be set to allow the things to be towed well away from the ships side. Mine  wire cutters?
And that’s about it for the focsle. But finally, I must mention the inboard ends of the port side mast shrouds. They are set well inboard because the gap between them and the ships side was occupied by the huge steel plate that simulated the false after superstructure and  false funnel. God alone knows what havoc that played with visibility from the bridge…and I won’t mention the effects of wind etc!

Time for a stroll around the tank deck.
Talk a bit about the real ship before doing the modelling bit.
Down the (single) ladder on the port side. Turning sharp left avoiding bumping into the cargo tank hatch and under the hydroplane deck extension and probably tripping over the spare anchor. This area had an odd purpose during WW2. Under the focsle head was all storage space, with a dry cargo hold below (both areas could be accessed via the cargo hatch on the focsle). Under the canopy and within the focsle was racked storage space for about 50 tons of bagged coal. Coal? During WW2? Surely ships weren’t still coal powered? Nope, but many of the older ships still had coal fired galleys, so the coal was pretty important. The focsle, then as now on an RFA was also the main storage space for all the spare RAS gear. Amazing how many hoses could be needed, not to mention what appears to be miles of coiled wire rope, manila and so on, plus tons of “hardware. More down the hold, which could also hold stuff possibly required/requested by RN ships that didn’t have the carrying space. I presume that the ammo was kept here as the “ready-use” lockers are just that and don’t hold much. But you get the idea.
Emerging from the focsle door (still during WW2), you will probably be confronted by a fairly high stack of long wooden boxes secured in purpose made “pens”. Within these boxes were fighter aircraft fuselages and in others, the wings for them. Obviously these things couldn’t be transferred to other ships while at sea…we didn’t have the technology then. But they were being carried as replacements, additionals and so on for the Russians.
Don’t worry about the large funny looking boat on the starboard side. We’ll get to that soon enough.
Note that all the tank lids have a counterbalance weight on the hinge side. They’re needed. Those lids are heavy. They should also have “sighting ports on the lids. Looks like I forgot to put them on…slapped wrist here! A sighting port is basically the same (but smaller) as a cabin scuttle complete with deadlight. For such an apparently minor item, they are really of vital importance. For a start, when cargo is being pumped into or out of a cargo tank the displaced air has to go somewhere…or get into the tank when discharging. When loading there’s a real gale of oily air rushing out of this 6” or so “hole”. What does that have to do with being called a “sighting port? Before the advent of loading gauges and so on, the only way to tell where the level of loaded oil had reached was for somebody to shine a torch down into the filthy abyss and count how many rungs of the access ladder were visible. Even in the 1980s when on an “OL” class ship, the gauges were “unreliable”, and so the loading officer had to do it the old fashioned way and be prepared to get a hefty faceful of FFO, Deisel or Avcat. Ah, the delights of life on a tanker!
In all of these deck photos you’ll see “venturi ejectors” scattered around. The sort of trumpet shaped thingys. I hate to admit this, but for the life of me I can’t remember what their prime purpose was! Gas blowoff? Steam smothering venting? Sorry, can’t remember. You’ll also see small bore pipes running between the various hatch coamings. I seem to recall that they were air/gas balancing pipes. That’s OK if you only have tanks carrying the same stuff..in this case it would be all FFO. Otherwise it would be a no-no.

Continuing our Saturday walkaround ….an informal inspection before Captains Rounds on Sunday morning. A quick glance at the Carley Liferafts..just a quick eyeball to make sure that everything that should be there is there, check the lashings and release gear. No-one is going to pinch the spare prop, but check the tie-downs havn’t worked loose. All tank lids tightly fastened? OK. A quick eyeball into the top of the pumproom to say hello to the pumpman whose bailywick this is. He comes as part of the Ch.Engineers staff, but has to work closely with me. A mistake by him could cost me my job….or worse. A very important man is our pumpman.
Now we turn around and meander for’d again up the stbd side. Same as for the port side except for the huge 6ft diameter leaf that’s somehow landed on the deck. This distracts me from inspecting the main pipelines, but as there isn’t any sign of leakage I let it pass. Then I come across Seaman Staines writhing in agony on the deck. But it’s a minor thing, and hell be on his feet soon enough. 
Now we come to the last item of note on the tank deck. The “ Little Ranger”. .
This “boat” is only a boat in the sense that it floats. It’s also the main reason that the ship is fitted with a 20ton SWL derrick. You may also notice that this thing sits on a bogey which is sitting on rails. The rails continue under the focsle. Open the sliding double doors and the “boat” can be pushed into the focsle space. It is, in fact, a petrol carrier. Carries about 6 tons of the stuff and emits fumes. Always a worry. For some reason the warships of the era had petrol driven motor boats…so petrol was needed.  The boat had to be lowered to the water and towed to the customer. As with all the boats carried aboard “Gold” it was made of steel.
Having done my foredeck walkabout, it’s time to look at the modelling aspects of all this. Next time.

However, while leaning on the rail at the aft end of the focsle head, contemplating , well not very much really, but thinking how much nicer the wheelhouse is without all those splinter cushions and so on plastered all over the place. The next time I’d see them rigged would be in 1987 when entering the Persian Gulf. Funny how all the world still calls it the “Persian Gulf” and not the “Iranian Gulf”. This must be a real niggle to Ahmadinijad. Tough.
But before I wend my way back to the bridge where I see the “old man” glaring at me, I’ve got a couple of moments to look at some modelling aspects of this old tub. Not the “catwalk”…that’ll be on my next walkabout.

As far as the modelling goes, I left you with a bare ply “false” b’d at the break of the focsle. This now had to be made into a completed one. This was made fairly straightforward by not having fitted the bulwark/fashion plating that runs along the ships side and swoops up to the focsle.
Using the template I used to get the deck camber in that area it was easy enough to mark the bottom edge of a piece of 30thou plasticard….cut overlength so it would overhang the ships sides, then did the same for the top edge…but making the height about 1/8” higher than required (this would be the deck edge “upstand). Then the centre part was trimmed out so the card would slide under the hydroplane deck. When offered up to the bare ply, the ends (P&S) could be marked and trimmed to fit in the flare of the hull at that point. The various fittings such as the WT door, the 2 sliding doors and their guide runners could be made and attached before painting and sticking the completed b’d facing panel to the ply.
I should mention that all the painting on this model was done with a brush as Humbrol didn’t seem to do an aerosol or the required shade of grey.
The back of the plasticard panel was then covered with double sided tape and (very) carefully offered up to the raw ply underneath.
Now that the fcsle b’d was fitted, it was time to turn to the bridge front area. Really just to check that I’d got the curve of the deck correct before I did some marking out.
    By now the deck had been laid (but not plated) using my standard method of cutting ¼” thick ramin with a top curve to suit the deck camber before overlaying with 1/16” ply. I tend to use slow setting Araldite for this job…especially around the deck edges. Lots of clothes pegs and weights all over the place.
Now I’ve got a large area of nice clean deck to do some marking out before I could do some cutting out.
      I’m beginning to wonder if it was wise to do the photographs of the model first. I think I may have to combine the “real” with the model build in a different way. This way seems to be a bit on the clumsy side.

Thanks Derek....all comments (good, bad or indifferent) are welcome!
Earlier on I mentioned that the RFA had a bit of a penchant for odd looking ships. I mentioned the "Eddy" class.
Also deemed a Fleet Attendant tanker, this class wasn't all that much smaller than the Rangers...about 40 or 50ft shorter.
At sea and fully loaded they made an odd sight. Three disconnected lumps sailing along in close proximity.

Right. Now Iv’e got a nice clear and clean drawing area to mess up.
The deck camber being quite prominent will make jobs like getting all the tank hatches, pumproom etc to sit vertically and matching up means that the hatches will have to be “sunk” under the cambered deck and fastened to the flat underdeck…and fitted before the litho-plate deck plating is done. Gosh, to make a model like this I reckon that the buider must have a masochistic streak a yard wide.
So, the tank hatch openings are cut out to a size that will take the 1/16” ply basic structure, and the 30thou plasticard covering will be cut and fitted to touch the cambered deck. Make sense? So for the moment I’ll just make the basic structures.
Make a similar “hole for the pumproom structure to slot into. I suppose all these “bits” will have to be made as little models in their own right….but then, just about everything on a ship is a separate “stand-alone” model and only become part of the whole when fitted.
It looks as if I used 5 strakes of deck plating…seemed about right for a ship of this beam. The “low point” of the deck was fortunately more or less at the point where the superstructure began. Makes thing just that bit easier. So starting from aft, the outboard strakes are laid. This first strake is straightforward with one exception. The overlap of the plates in the same strake is about 1/8”….but (and it’s a big “but”)…laying subsequent strakes means that 3 plates will meet at various points. This can cause a nasty and very visible “bump”. My way of avoiding this is to cut the overlap of the underneath strake back by a 1/8” square so the strake lying over it can lie smooth..or nearly so. The strakes are not laid like bricks. Instead, they are staggered (much like the builder). Being only 3 strakes (centre one doing duty for both sides) it’s easy enough to work out the stagger to give maximum separation between the plate endings. Being countersunk riveted there’s no need to mark the rivet heads…a coat of “deck paint” would hide them anyway. The good old double sided tape takes care of the clagging down. Then after removing the hatches an so on, the whole deck can be painted. Looked nice when first done, but looking at it now, I think the slight grubbiness suits it better…tank decks are always awash and get pretty manky no matter how well they’re looked after.
It isn’t unusual for the odd overlap to lift a little..but a drop or two of superglue or a smudge of Bostik soon cures that.
Hatches and Carley floats next….with pictures (!).

Tank hatches come in a variety of shapes and sizes. Don’t see many square ones nowadays though. Different construction techniques (welding being one) and the size of the tank cleaning gear used nowadays. Also, “oval” or “round” ones probably don’t take as much of a battering from the sea as a square one. Some of the modern ones…most of them probably…are opened hydraulically or by some other mechanical means. They are just too heavy to be opened manually. In fact, they aren’t “opened” in the conventional sense at all. Just lifted enough to clear the seals and then swung sideways. But not on the “Ranger”. “Mandraulic” was the name of the game. As you can see, they are of simple construction. Just a square box with a couple of angle brackets to the deck, a stiffening piece where the lid seal sits. A slightly oversize stell plate lid with screw down locking clamps, hefty hinges and a counterbalance weight.
Plus a sighting port and a tank number painted on the lid. Seemples.
I suppose I could have put a reinforcing angle strip down each corner..but I didn’t.
On the model (reminder;- 1:48 scale, ¼” to the foot)…the hatches are 1.5” square and 0.75” high.
The photos show a bit more than the hatches, but that’ll next time.

The spare prop was securely lashed down, but after a few years I imagine that rust had fastened it to the deck even more effectively.
In the previous pic there are a a few variations on the theme of “valves”. The valve shown between the float and the ejector is a “make do and mend” thing. At the time of building I’d run out of small handwheels, but a bit of sideways thinking showed that one half of a dressmakers press-stud would look pretty reasonable.

I think I could mention here that even with all my (minor) cost cutting, the completed model cost me over £1600 altogether. £1600 is when I stopped counting. But spread over the time it took to build I sort of ignored that bit.
Considering the length of time I spent ploughing the worlds oceans and more often than not, going to places seldom visited by ships of the regular “Merch”, I find it a bit odd that never once did I set eyes on a “Carley Float”. Oh,yes, I’ve seen rather fuzzy photos of them both aboard a ship and filled with survivors from one disaster or another. But never saw one “in the flesh”. So the ones I made for the “Ranger” may or (more likely) not be accurate. From some pictures I’ve seen some had “solid” floors, and others didn’t. They all appeared to be usable whichever way up they happened to be. I also had no clear idea about the on-board framework that served as both a storage and a launching unit. Except for fuzzy photos. So try to forgive me if I just built something that I though might just work in real life.
It was only after buying the EMA catalogue with a view to making up the pipelines and so on that I realised that the various bits could be put together to make a fairly accurate facsimile of a “Float”. Latch the bits together, fit a few bottom boards, make a couple of crude paddles, add a few bits of rope and paint and job done. Easier than I thought it would be. The mounting structure was a bit more whimsical. But as I was pretty sure that these ubiquitous floats wouldn’t have standardised mountings I came up with my own design which is either better or worse than something dreamed up for use in real life. So I’m sort of happy with them. All made out of various sections of plasticard. Even if I’m wrong, the fact remains that they were genuine lifesavers during WW2. Roll on the advent of the RFD inflatables! At least the modern ones have hydrostatic release gear so that even if the sinking ship is under the water the liferafts will self release and pop to the surface fully inflated.
Now I’ve got to move on to the petrol boat.

Hi Brian, modelers of your calibre are an inspiration to us all & certainly adds to my motivation to build better & more detail into my models, I find myself backing up & trying to do a better job the second time around, thank you for sharing, Mick B.

To the petrol “barge”..I was going to say Petrol Lighter, but some bright spark would be bound to ask if was called “Zippo”
Being a “dumb” barge (no engine) it would, of necessity have fairly substantial towing/mooring posts fitted at each end. Apart from the bulk storage area there would also have been a “dry” storage area for such things as a variety of hose couplings, Jerry Cans and towing/mooring ropes. Hence the “normal” hatch lid. Being both dumb and double ended I don’t suppose it made much difference which way round it was stowed aboard. Perhaps the dry hatch also housed a pump of some sort, but I still reckon that may have been a tad dangerous.
A (very) slight digression….speaking of petrol reminds me of a product that I was introduced to back in the 1960s called “Av-Tur”. As a warning to me about the volatility of this stuff the C.Officer got hold of about a thimbleful of it and just poured it on to the deck. It exploded quite dramatically! Point taken,sir.
The boat is about 6” long, and pretty crude. Deliberately. As with most things aboard this ship and the conditions she operated in and the lack of cosmetic repair time I believe that all the exposed bits would look pretty care-worn. The hull is actually GRP. The “plug” I simply carved in 2 halves from a bit of some sort of wood. No plans…just did it by eye and made a Plaster of Paris mould. I  suppose from picking up the bit of wood to having the finished hull only took a few hours. As you can see, the deck is cambered, and in one photo at least the non-skid checker pattern plate is discernable. I used the same checker plating on the treads of all the steel ladders on board. (Plasticard stuff, by the way).
The construction of the main carriageway..for want of a better name..doesn’t really need words as the photos more or less explain it all. All plasticard sections again.
The travelling “bogey” is also straightforward enough…but I managed to make it too narrow for all the wheels to fit on the carriage rails. So on the principle that the inboard side would be the least noticeable to a casual eye, the inboard bogeys are “derailed”. No-one has picked me up on that mistake as yet! I also managed to make the whole assemblage too high for it to be rolled though the sliding doors. Sloppy workmanship,Bryan. Slapped wrist time again.
I hope all that reads OK. Had a lousy night with a gout attack and am now a bit dosed up with pain-killers…that’s also the reason for the unearthly timing of this post!
I suppose I’d better do the pipe laying next.

Bryan,

I know that my brain is (almost but not quite  :P ) as addled as yours but my brain cell is telling me that those venturi devices you referred to in #11 were an early form of tank gas-freeing equipment provided before steam-driven fans were introduced.

Cheers,

Barry M
