I'd never copper plated before I my Pegasus, to be honest, it's not a hard thing to accomplish, just a bit tedious. Andy

Just a thought... If you go with a door, typically ship's doors open outwards so that water pressure would force the door tighter into it's frame (just like the gun ports), making it easier to keep weather tight. A door opening inwards risks getting blown open by the first wave that decides to crash the party. Andy

Maybe it's just me.... But it seems like the hinges were moulded on the outside of the door frame, and not the actual door.... Most modern weather tight doors should stand proud of their frames anyway. If it was up to me, I'd fill in that concave door and redo the porthole and handle at the new surface. Otherwise, the closest is the one on the right in your photos. Andy

I see what you mean in your second photo. It is most likely hiding a steam safety valve (pop valve). This is a sprung valve that will lift if the boiler experiences too much pressure. I'm guessing the pipe was added to keep live steam from blasting directly into the engineer's and fireman's faces. Here's the inner workings: In your sketch, live steam is collected in that funnel shaped pipe in the steam dome. At the base of that is the throttle valve. This is a saturated steam engine, so there is no superheater, the steam is then sent directly to the cylinders. The straight pipe coming up from the cylinders is the exhaust pipe. You can see how it narrows as it extends, but flares just before the base of the stack. By forcing the exhaust steam out at high speed (but not high pressure) it creates a vacuum in the smoke box (that's the compartment ahead of the boiler flues, the pipes leading from the firebox forward). The vacuum creates a draft drawing air from gratings under the fire bed, through the fire and forward through the boiler flues. The effect of this is creating a very hot fire. Hot fire equals more steam generated in a given amount of time equals greater speed/power from the cylinders. More modern locomotives used a small steam driven turbine to draw air when the locomotive was not being worked. The other "dome" (with the lever) over the firebox is most likely part of a pump/injector system to get water into the boiler. Later locomotives do not admit cold water directly over the firebox. This is partly the reason so many early locomotives blew up. If the water in the boiler became too low and the crown sheet (top sheet) of the firebox became uncovered, a panicked injection of cold water would cause it to fracture. Steam at pressure would rupture the sheet, drastically causing the pressure in the boiler to drop, which in turn would cause any water remaining in the boiler to immediately flash into steam. Steam increases in volume 1600 times from water (at standard atmospheric pressure), considering a boiler of the size you've got, a volume of, say 1.5 to 2 tonnes, you can just imagine the effect. Another thought, is it possible your engine would have been of the "Planet" type (like your picture)? They where one of the earliest locomotives produced in large numbers, starting around 1830. Even by the late 1830s they were starting to be superseded by more improved designs, which would have made some of them available on the surplus market. Andy

This steam fan in me just has to comment.... An exhaust steam pipe would not have some off that dome behind the chimney. Live steam is collected with an internal dry pipe and sent to the cylinders, whose exhaust is sent via a venturi tube and petticoat up the main chimney. This is how draft is also created in the firebox. I could go on at length...but that might bore some people Andy

Using a pencil jig is about the most accurate way to do it. Make sure your hull is level and you work on a flat, smooth surface. A string, no matter how tight you pull it, will always find the most direct route form point A to point B, unfortunately over a curved surface, it's not necessarily a straight line. Andy

You sure it's not some deep seated psychological fear of starting another build? Subconsciously sabotaging spars in order to postpone the inevitable...? Andy

HMS Sussex by mij - Scale 1:48

Looks like a very interesting build. Don't see too many ships of this era being built. Nice collection of workshop toys too... Andy -
Need help with Revell U.S.S. Constitution
realworkingsailor replied to Kimberley's topic in Plastic model kits
If you're up to it, start a build log, when and if you get stuck, post some photos and you'll be mobbed with help and offers of assistance. It's often easier to help when it's just one step at a time rather than a generalized "Help me with everything". Don't feel bad, though, we all started somewhere, and we've all gone through the same experiences. Andy -
Thanks guys! I'm on my way to the airport as we speak. As soon as I can, I'll get my camera unpacked and ready for the continuation of my other thread. Andy

Need help with Revell U.S.S. Constitution
realworkingsailor replied to Kimberley's topic in Plastic model kits
Hello. The basic knots you need to know: Clove Hitch Half hitch Reef Knot Figure Eight Knot Bowline Learning those five should get you started rigging. Have a look here: http://www.nauticalmind.com/Knots-c-400.html Some great introductory books on know tying to help you figure out each knot's purpose. Hope that helps a bit. Andy -
Based on what little I've read about the subject, snaking was only done in wartime, so leaving it off would not be a mortal sin... Andy

Why not try a brig like the MS Syren, or Niagara. Or one of the Caldercraft collection (Supply, Badger, Cruizer, Mars or Jalouse). Or if you want, the Amati Mercury. If you feel up to it go for three masts, the Amati HMS Fly or Pegasus, or the Caldercraft HMS Snake. All good high quality kits with a sizeable following On MSW. Amati follows the same construction style as Caldercraft so they would be a good warm up/prep for what you would experience with the CC Vic. Andy

Kevin, thank you very much. I'm looking forward to your progress. I see you slowly inching your way towards rigging. Wes, I hope I've done ok for you as far as the picture department goes. As for a serving machine, I ended up making my own, there are many variants out there from other people, find one you like or are capable of putting together, and you'll go miles. Andy

About the NRG
If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.
The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.
The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
