Some quick progress photos of the boat - and its a big beast 3ft long!  I have decided to set it in the late 40's early 50's as a sternwheeler workboat with a marine boiler (coal fired) old-type engines working in India or Far East on river/canal dredging duties. It will have a Ruston No.6 steam grab crane for those purposes situated at the bow of this flat fronted boat. The engines and boiler are scratch-built in styrene (scale 1/24th). The most recent addition is a small diesel powered generator to provide lighting and power to electric pumps. This came about when Barney kindly donated two of his engines. The generator is made up of odd bits from the scrapbox.

Looking really good but I wonder if that one boiler is large
 enough to run both long stroke engines.

Bill, I was thinking the same myself.  At the moment I just couldn't face replacing it with a larger one.

Take two steps back - sit down have a nice tot or two(or maybe 3 or 4 ) But the Boiler has just got to go - We have all been there before but its got to be right or you might end up " in the corner "
IT defiantly does not look big enough - and as Bill and I and perhaps others suggest it "a Constructional Criticism only" not a personal view !  But the quality of building is 5 star

Well its 2 steps back for me !!  and a in-depth look at marine boilers (images of on Google) and the conclusion is Les has Got it right - it looks like most marine boilers are "short and chunky"
so apologies to Les - at the moment it looks a bit lost on the deck but Im sure it will look better when in its own little room/space with a bit of junk around it ! if that's what the marine people call it

Catching up !

Lovely work Les, interesting comments re boiler ……… think maybe people are basing their views on railway boilers rather than marine ones . Different designs and types railway boilers can be long and narrow in diameter , in fact have to be but marine designs allowed for the development of a short but large diameter boiler with the best known type being the Scotch boiler where for your application a typical size could be around 10 ft in length and a diameter of 10 feet ……. You can understand from diameter why they were not a practical choice for the rail user  Cheesy

Thanks Barney and Gordon for your comments and Bill for the e-mail aswell. After lots of thought (plus a glass or three of something nice and strong!) I have come to the conclusion that the boiler sits too low on the deck, the poor fireman would get back-ache firing it. So I am going to lift it the equivalent of a foot or two. This should then make it look "bulkier" and a better proportion.  I'll let you know.
