    Cathead got a reaction from mirek in Heroine 1838 by ggrieco - FINISHED - Scale 1:24 - Western River Steamboat as she appeared before hitting a snag in the Red River   
    I'm not sure about the initial aspects of the procedure, but as far as removing the hot material safely from the boat, many boats had a special ash trough that allowed the hot coals & such to be swept/washed away from the boilers, either over the side or through an opening in the guards. Here is a picture of the brick-lined ash trough from my Bertrand build.
     

     
    As for boiler explosions, they were quite common on western riverboats, due to a combination of high-pressure boilers, limited or no safety equipment (such as dial pressure gauges), limited knowledge/training of the engineers running the boilers, and a commercial (and passenger) culture which favored speed and power over safety and caution.
     
    For a long time, the only safety valve on riverboat boilers was a simple weighted lever, which was very easy for an ambitious engineer to over-weight or even tie down, increasing the pressure in the boilers. With no clear testing or standards, no one really knew what pressure boilers could hold, and there was no calibrated way to measure pressure. Water levels in the boiler also couldn't be measured easily (again, no gauges), so this too was guesswork and instinct. Thus, if water levels got too low, or levels fluctuated as suggested for Sultana, boom with no warning.
     
    All of this was made much more likely by the river culture of the time, in which the fastest boats received premium rates and reputations, regardless of safety concerns. In addition, river conditions could lead to explosions, as when boats attempted to force a bar or round a bend under high-water conditions, needing every ounce of steam in the attempt. One particularly deadly explosion in central Missouri happened after a boat repeatedly tried to round a bend in front of a towns-worth of onlooker, failing over and over and being swept back downstream in embarrassment, before the engineer apparently tied down the pressure valve and went for it all. The boat blew up mid-bend, sending debris into the onlookers on the bluff and killing many passengers.
     
    Glenn, I'm curious how you know the Heroine had four boilers. The number varied from boat to boat; I was surprised to learn that Bertrand only had two. Also, do you know what kind of pump the water supply used?

    In return, it's not clear (at least to me) how Jerome Petsche's reconstructions decided Bertrand had two boilers (they were salvaged shortly after the wreck, as I assume Heroine's were, iron being so fantastically valuable on the frontier). His drawings show them as such, but he doesn't discuss that aspect of the reconstruction in his book. It may have something to do with the dimensions and layout of the supporting structures for the boilers, which were preserved in the main deck of Bertrand and (I assume?) also on Heroine. A given width of support timbers may strongly suggest X number of boilers, given that most were made to similar plans/dimensions. Just to show the uncertainties involved, a privately-drawn set of Bertrand plans I initially started working with, before setting them aside as too inaccurate compared to Petsche's data, have Bertrand with three boilers. 
     
    It's all very confusing.

    Hello Cathead,
     
    Thank you for the information. We are not sure if she did have four boilers. It was an early assumption that Kevin made and I'm don't remember what the justification for it was. Comparing the vessel to Bertrand, l'm wondering if we might have had only two. I will see Kevin this next week and discuss it with him. I sure would be happier building only 2. As for the water pump, there is a 9 inch wide notch cut in the cylinder timbers at the forward end of the cross head slide. We are certain that this supported the lever for the feed water pump. Working off of a linkage to the cross head, the lever would have operated a low pressure pump that pumped water to the preheated shroud around the steam exhaust and a second high pressure pump that transferred the water from the shroud to the boiler. I have drawings of the arrangement but unfortunately they are at the office. I'll try to post them early next week.

    I'm not a sail expert, but wouldn't it partly depend on the conditions and context? My limited understanding is that topsails were generally used for light maneuverability in square-rigged ships, so in theory would often be the first set from a standstill, but I'm not sure of the procedure on a schooner rig.

    A clarification: pre-scribed wood is just what the doctor ordered for a situation like this cabin structure, but I didn't do the scribing myself. You can buy sheets of pre-scribed wood in various thicknesses, dimensions, and styles. For example, you can get plank-style like I used, or board-and-batten. I've built a fair amount of structures with it for my model railroad (based on a Missouri River port town during the steamboat era), and have a variety of scrap left over that was easy to repurpose for this project.
     
    I used it here because building a frame and planking both sides would have made the walls far too thick at this scale (1:87), and I don't have any wood thin enough to do that in scale (and I'd be afraid it'd be too fragile anyway). These boats were built cheap and fast, and these stateroom walls were knocked together from thin pine. Actual framing worked fine on the main deck, because those walls weren't finished on the inside and so it's necessary to show the framing, and doesn't look too thick because you can't easily see the ends. But having stateroom walls well over a scale foot thick would have looked ridiculous; if nothing else the windows would have looked wrong, either too thick or too recessed. I couldn't see another way to show cabin interiors without using solid sheets of wood at this scale. If I'd built the cabin whole, I probably would have framed and planked it, because I wouldn't have cared about the interior look or depth, but saw this as a compromise to allow the interior view.

    Finally got the re-rigging(aged ropes) finished on the 12inch smooth bore. It turned out to be quite interesting to remove and replace the ropes with the cannon affixed in place. So if anyone needs a lobotomy???
     
    Any how, I picked up some muslin to begin working on the sail. Turns out it's almost exact to the kit supplied sailcloth so let the experimentations commence. I also found a blank, white handkerchief swatch in one of my vintage boxes of DMC and am trying a few coloring methods for the sails. Now I just need to get my hands on a yard of the hanky material. It's so thin you can see through it, so I'm not quite sure how it'll work out.
     
    One thing I've been searching for and haven't found yet, is the order in which the sails would be set from the furled position. I'm thinking of having a sail or two opened to the wind, but not sure which one(s) that would be. So if anyone can point me in the right direction, it would be greatly appreciated.

    Here are some quotes which may shed some light on the question. All parantheticals mine; also any errors, as I transcribed these from the printed books. "The West", as used here, means the interior river basins of the United States, i.e. the Missouri, Mississippi, Ohio, and such, rather than the West of the Rockies and beyond.
     
     
    From Steamboats on the Western Rivers, an Economic and Technological History, by Louis C. Hunter, p. 124-125:
     
     
     
    From The Western River Steamboat, by Adam L. Kane, p.68-71:
     
    My understanding has always been that steamboat machinery was largely manufactured in situ in the west, as it was prohibitive to ship heavy machinery over the mountains from the east, or up the Mississippi from New Orleans (where there was no heavy metal industry to speak of at the time). Pittsburgh very early on developed iron working industry, and almost all western river boats were built along the upper Ohio River within easy reach of Pittsburgh's industrial capabilities. Thus it seems possible, even likely, to me that most steamboat engines, particularly any high-pressure ones, were built with steamboat use in mind, rather than being re-purposed industrial engines from some other source. The early ones may have been based on generic industrial designs for sawmills and such, but I'd bet Heroine's engine was built near her boatyard with her in mind.

    Also, I've been skimming through a few of my references, which imply that steam engines were being adapted or designed specifically for western riverboat use pretty early on, certainly by the 1830s. So it's also possible that Heroine's engine, while based on a factory design, was also custom-built for her along similar lines. Certainly a number of early steamboat engines were salvaged from wrecks and put to use in basic land settings like sawmills.

    I was almost able to complete the engine this week.  All that remains are the throttle handle and feewater preheater on the exhaust.  I fitted the flywheel bearings and the cam frame supports.  The next step will be position the remaining six bearings in-line with the flywheel bearings.  I'm planning on using a round beam from a beam compass and sleeves turned to the proper journal diameters to guarentee alignment.

    Well, my beloved Royals have won the baseball World Series, and I'm back to work on the Bertrand. 
     

     
    The main deck structures are complete, and I've mostly finished framing up the boiler deck. This was surprisingly difficult, as there's no flat frame of reference (the main deck curves in every direction). Getting the support posts vertical in both directions was quite interesting. I've been very bad about taking "process" photos during this stage, so you'll just have to imagine things. The only consistently flat frame of reference is, oddly enough, the bottom of the hull. So I made a complicated jig of solid wood strips clamped to the hull, from which I could extend vertical squares, onto which I clamped cross-ways strips, to which I could clamp the vertical posts. Fiddly, but effective. I also made strong use of the eyeball; I'd rather a line of posts LOOK straight relative to each other, even if they're slightly out of line relative to true vertical.
     
    Once the posts were in place, I began adding cross-pieces. Technically the boiler deck should have a slight bit of camber to it, but I decided that would be too difficult and would be barely visible at this scale, as most of the deck will be covered by the cabins. The more significant camber of the main deck shows up nicely, and is sufficient for my taste. Thus the deck is flat athwartships, but curves gently fore and aft to follow the rise of the main deck in both directions. 
     

     
    I finished planking the main deck as far I as intend to; this extent will allow the model to look complete from a port 45-degree angle fore or aft, but still leaves plenty of internal view from the starboard side. It's a little rough in places, but will have to do. I'll put a crate or something over a few plank ends that stick up more than I'd like.
     

     
    View from the open starboard side. I've also finished installing the hog chain braces; these angled posts support metal rods running fore-and-aft, with turnbuckles on them, which keep the long, narrow hull from sagging/hogging. I won't install the actual rods until near the end of the project, as they'll be in the way, but needed to do the braces now as they extend through multiple decks. They're intentionally a bit longer than necessary, so I can cut them off just as I like them once I finish the superstructure. 
     
    Currently I'm building the boiler assembly, which sits just forward of the cargo shed on the main deck. I intentionally haven't installed the vertical support posts at the front of the boiler deck, to allow me to slide the boiler in there. Once it's in place, I'll finish that area and install the staircases (already built) just in front of the boilers.
     
    I think things will go rapidly for a little while, now. Install the boilers, connect them to the engines with steam lines, plank in the entire boiler deck, and then move on to building the cabin area. I still have to decide whether to order a bunch of styrene windows and doors, or try to make my own out of strip wood. The former would be far faster and more consistently detailed, but more expensive and hard to make look just like the surrounding wood. The latter would take a long time, but be a lot cheaper and fit in better if I can make them realistically enough. I'll decide once the next deck is done.
     
    I'm holding out hope of reaching my goal to complete this model by the end of the year. Luckily the approach of winter means nice long evenings for quiet model work. She's certainly starting to look something like a steamboat. In the meantime, here's a fine Ozark fiddler playing "Jefferson City", one of Bertrand's ports of call on her way upriver.

    Well, she doesn't look much different at first, but some detailed work has been done.
     

     
    After a fair amount of consulting and cogitation, I settled on a design for the engines. As we have no idea what Bertrand's machinery actually looked like, I went for a representative approach; something that would capture the spirit of typical steamboat engines for the period. Something like this:
     

     
     
    Experts will recognize some missing details; some will be added as I progress, some I didn't think I could replicate well enough to include. For example, I haven't yet added any of the overhead piping that brings steam to the cylinders from the boilers (forward), or the chimneys for cylinder exhaust, both of which will be easier to do later as I progress on the superstructure. But the overall effect is good enough for me.
     
    Also completed are the tiller arms, and one side of the bulkheads that separate them from the engineer's main work area. The starboard side won't be built to keep the view lines open from that direction. Note the scratchbuilt workbench forward of the bulkhead. That was a fun little side project.
     

     
    Photos from the museum model were useful in getting drivers reasonably right. I also built the aft bulkhead, painted red as on most steamboats of this era. The wheel really turns, though the drivers don't (I wasn't up for making working pistons). Later I'll be adding the various bracing that supports the weight of the wheel, but not yet.
     
    Next up, framing up the rest of the main deck superstructure and walling it in. Then the various angled hog chain braces and their iron rods, then finishing the decking, then building the boiler and remaining machinery and running the necessary steam lines. 
     
    No idea when the next update will be. Baseball playoffs will be a major time sink for the next month until the Royals' season is over.
     
    EDIT: upon re-reading, I fixed an embarrassing error. I referred to the main and boiler decks as the same thing, which they're not. The boiler deck is one level above the main, despite the boilers themselves being on the main. I knew this, but it's easy to confuse if you're not paying attention. I've never seen a convincing explanation of why the boiler deck is called that, but it has always been so on steamboats to the extent of my knowledge.

    A clarification: pre-scribed wood is just what the doctor ordered for a situation like this cabin structure, but I didn't do the scribing myself. You can buy sheets of pre-scribed wood in various thicknesses, dimensions, and styles. For example, you can get plank-style like I used, or board-and-batten. I've built a fair amount of structures with it for my model railroad (based on a Missouri River port town during the steamboat era), and have a variety of scrap left over that was easy to repurpose for this project.
     
    I used it here because building a frame and planking both sides would have made the walls far too thick at this scale (1:87), and I don't have any wood thin enough to do that in scale (and I'd be afraid it'd be too fragile anyway). These boats were built cheap and fast, and these stateroom walls were knocked together from thin pine. Actual framing worked fine on the main deck, because those walls weren't finished on the inside and so it's necessary to show the framing, and doesn't look too thick because you can't easily see the ends. But having stateroom walls well over a scale foot thick would have looked ridiculous; if nothing else the windows would have looked wrong, either too thick or too recessed. I couldn't see another way to show cabin interiors without using solid sheets of wood at this scale. If I'd built the cabin whole, I probably would have framed and planked it, because I wouldn't have cared about the interior look or depth, but saw this as a compromise to allow the interior view.
     
    avsjerome, thanks for that snippet. I've read about the steamboats on the Columbia and such, including the famous first trip down the rapids showing that it was possible, but I never knew that Idaho itself was named after a steamboat.

    With the boiler deck planked, apart from a section I left open for internal views, I moved on to building the cabin structures. 
     

     
    Typical riverboats of this design had two lines of crew/passenger cabins (usually called staterooms), separated by an open main cabin (or parlor) down the centerline in which meals were served and folks could socialize. Only stateroom passengers were allowed in here; those paying for deck passage fended for themselves on the semi-open main deck. The forward-most staterooms would be used by the captain, pilot, clerk, and engineer, then a few mens' staterooms, then a larger room on each side used as galley & storage, then more staterooms aft. Generally the aft-most section of the main cabin was carpeted and reserved for ladies & families only, along with the aft-most staterooms, to save their exposure to cigars, spittoons, cursing, and other male tendencies of the period. 
     

     
    The boiler deck has a slight, but clear, sheer both fore and aft (especially aft). So I couldn't just assemble nice, straight walls and set them down, I had to account for the curvature of the deck. The longitudinal walls were built in three sections, with notches to help each fit together. I filed slight angles into these joints, so that the sections fit together in a subtle curve, matching the deck. I cheated slightly with these, using sheets of pre-scribed wood rather than building frames for individual planks, as I did for the main deck structures. However, I did build all the doors and windows from scratch, as advised by the commentariat.
     
    In the photo above, the top row are the two ends of the cabin structure (one turned over to show the bracing for the walls), the middle row are the outer walls of the port staterooms, and the lower row are the inner walls of the port staterooms. Lady for scale. I only build the port-side walls, leaving the starboard side open for views of the inner main cabin.
     

     
    I started installing the walls by clamping squares across the deck to guide the fore end (not sure "bulkhead" is appropriate in this context). Then I glued guide strips of scrap wood along the deck, inside the runs of the port walls where they wouldn't be seen, and used these as gluing and clamping guides for the walls. Each 1/3 wall was glued in, then the next one sanded to fit and glued in, then the last one.
     

     
    Above is the completed cabin structure. By not exposing the interior of the port staterooms, I was better able to support and straighten them with internal stringers. In return, I built two open-sided staterooms at the fore and aft end of the starboard side, to allow a view of the interiors, but left the rest open for better internal views and light. The main cabin should have tables, chairs, wood stoves, chandeliers, and so on, but I'm not up for building all that right now. I'll always have access to this area if I choose to detail it later on.
     

     
    A closeup view showing how small these staterooms were, just two bunk beds at most 6' long and perhaps a small cubby for hanging clothes. These were rough frontier boats, not the floating palaces of the lower Mississippi River. Toilets and laundry facilities were at the stern, and will be built and explained in a later post. In this photo you can also see that I managed to install the forgotten engine vent stacks just fine (note: the main smokestacks were actually called "chimneys" on riverboats; I don't know if this terminology extends to smaller stacks).
     

     
    Main cabins had a raised clerestory with skylights along the length, allowing light into this central area. Thus I needed to build two of these long, narrow structures complete with regular windows, but strong enough to span the open, unsupported stretch on the starboard side. I did this by laying out two parallel beams on double-sided tape, then setting my cutter to the inside dimension and cutting lots of filler pieces. Using spacers, I laid out the window pattern along the whole structure, then glued in the spacers. When the whole assembly had dried, I peeled it off the tape, sanded it smooth, and painted it. I built two of these one right above the other, so I could visually line up the spacers and ensure the two pieces were identical.
     

     
    And here's the result, along with a good start on the beams supporting the hurricane deck (supposedly named for the constant breeze up there).
     

     
    And here's a better overall view from an angle, giving a sense of the cabin's overall structure and placement. 
     
    Next tasks:
    Frame in the rest of the hurricane deck (also serving as the cabins' roof), which extends forward as far as the boiler deck does, but aft only to the end of the cabins. In other words, the forward boiler deck is covered but the after boiler deck is open. Build the aft-most structure, housing the pit toilets (opening into the wheel) and laundry. Lay out and install the hog chains, iron rods which extend longitudinally through multiple decks and support the fore and aft weight of the boat, preventing it from hogging (particularly from the weight of the sternwheel). When I started this project, I had hoped to complete it by the end of the year. That seems unlikely now, but the end is nevertheless in sight. It's exciting to see the Bertrand really taking on its full form, beyond the barge-like appearance it's had for so long. No music this time, too busy to come up with something interesting. Thanks for reading, and Merry Christmas or whatever seasonal salutation warms your cockles.
