Title: Olde Spanish paper toy steam engine kit
Post by: ShadetreeMotorcycle on June 15, 2021, 05:24:48 pm
This is not my model but from a paper model forum I am on.

  The history of this old paper kit was quite interesting to me, it seems these kits where popular with children during wartime, as sales of our metal steam engine models where sometimes restricted to conserve precious metal for the war effort. There are a couple models like this that can be run on compressed air, but the This model actually has a paper (cardstock) turbine hidden inside the brick firehouse and the child was to use the paper funnel to pour clean dry sand down the chimney! (Somewhat like an hourglass timer) The sand would spin the turbine which is fixed to the same axle as main flywheel and the engine will spin.
  The sand can be collected in a tray under the base and reused.
  The kit could also be modified to mount a tube low in the firebox blowing at the turbine and powered with an aquarium pump...or at least that is my plan. I will post photos of my build if I get it working! I thought the artwork on this old kit was pretty cool.
  You can download the file for free and then you have to print on thick cardstock.

I am delighted to post the link!

The instructions are in Spanish, but it is not a vert difficult build (if you have built a couple paper cardstock models before)
Most questions can be answered by study the photos of the built model closely.
  There are 2 downloads, the A3 is a scan of the original and prints on 8.5"x11" paper.
  A4 is an enlarged version that most builders prefure and prints on 11"x17" paper. The A4 is slightly lower quality graphics, for brightest color I might recommend the A3 download, then just enlarge to 11"x17" or any size you enjoy on modern color printing equipment.
   The photos of the model I posted was built by a very talented paper cardstock modeler, I am positive my first one will not look this nice, however the beauty of cardstock modeling is if a part does not turn out how you like, you need only print off a new sheet and have another go at it, it is a Very low cost hobby and the opportunity to make upgrades is only limited by imagination of builder.

As the instructions are very sparse, and many details are left up to the model builder, I thought I might post a few more photos of the completed model for clarity.

[attachimg=3]

[attachimg=4]

The blue color on underside of base was an upgrade, the model builder laminated extra layer of a product called Mat board to make the base a more stout and flat structure.

Thanks for the info and the link. I will print the template right away. That the instructions are in Spanish should not be a problem. Most of the templates are self-explanatory. And then there are fortunately translation programs.😉

The model looks great in the pictures. Maybe I build the model together with my grandson.

Wow!  What a cool kit.

Last thing I need is another hobby. :)

I hope someone will try to build this and show it on the Forum.

I hope someone will try to build this and show it on the Forum.

Hello txlabman, I may be able to help with your request, I just got a packet of laser printed sheets from my local small town print shop! The laser printer does a beautiful job capturing the old artwork of the model, my print shop informed me that I can just email them the file for the next time, this will yield even better print quality as every time you make a copy of a "copy" there will be some loss of quality, however printing right from the free file to say photo quality paper could yield brighter prints than the original.

I have also ordered an air pump,(to run the model) this one is highly reviewed and I also saw it run a small steam engine on youtube, what I like about this pump is it has a dial on the top that controls volume, in this way you have a Very effective throttle control. I wanted a air pump for my other engines so this was not purchased just for the cardstock kit.
  I do want to try "Sand" powered at least one time! Just to get the old time full kit experience and also it makes me chuckle to think of an engine that runs on sand ;D
I hope to start building soon, I am also hopeful Dampfopa may also share his build on the forum as well!


[attachimg=1]

Edit: I realize to spin a turbine requires a Volume of air while powering a tiny piston requires perhaps less than 3 PSI pressure. If the pump will not power the paper model, I still want it for my small engines. It is available from 1 port all the way up to 8 ports with a price range of approx $12 to $55 depending on port count.

Here is a video of the 2 port running a model engine, I ordered a 4 port.

Update: I have not started the paper steam engine but discovered that the Spanish manufacturer of this kit also did a Motor Diesel with the same paper "water wheel" hidden inside the bricks to spin the Motor with sand stored in the fuel tower.
  The builder of this model goes by Thumb Dog and he is the same talented builder of the steam engine in this thread. He cautions that this model is more difficult to build than the steam engine. He left the sand power feature out of the build and flywheel spins by finger flick method. Thought I would share.

I have just begin the the construction of the Vintage steam engine!
  This paper is apox 100# grade, it is quite different to work with than the tiny lighted church kit I built, I decided to start with the sand/turbine as it is totally hidden from view and only needs to be structural sound, not pretty so a good place to get familiar with the heavy paper.
  The very old art is hand drawn and not nearly as precision as a modern kit, but still fun to work with, between the model errors and the difficulty getting the second side centered with the first, (my errors) my turbine is strong but spun with side to side run out aprox .050 although functional, this will never do for a Toolmaker so I simply opened up the axle holes with a needle file and added glue reinforcement square, but spent a little effort on better centering.
  The artwork on this part of the model is only to help locate the vanes as you build.



[attachimg=1]

I was concerned my 2.32 PSI aquarium pump is very low air volume output but much to my satisfaction my trued up paper turbine spools up nicely on the low volume output, this will be considerably cleaner to run than sand!
  The Turbine test stand is just a scrap of 100# paper folded in a U shape and a bit of pencil lead in the notches for lube. The test axle is sewing needle.

Roll forming the chimney:
  I am using a pool stick, but there are several ways to get the same results. What makes this work is the towel is soft so the pool cue can form the heavy paper.

I will follow the construction report with great interest. In the meantime I have downloaded the template from the net. Maybe tomorrow I will be able to print everything on A3. As soon as I have time (and my grandson has the desire) I will also begin with the construction.

Your beginning is already very promising.

Update:

Not a lot to show yet as I do most of my building in the cool of the evening during summer months. I did want to point out while most paper modelers build this kit printed on 11"x17" paper, my new print shop talked me into a size larger as they said it was there "best" cardstock, it is 13"x19"!!
  The lines on the enlargement are getting pretty wide at this size, but the larger parts are nice to handle. I will post a photo of the chimney next to a D20 chimney for size comparison, this is going to be a pretty large model. I have big plans to build the kit a second time with some upgrades harvested from paper model forum, but thought to build a prototype first to see what areas may be problem spots so that my fancy build may turn out the best I can make it. I will make a black paper tube to fit the top of chimney liner about 3" deep so the white interior does not show.

Some of the tools I use the most for paper model build. The assortment of sewing needles are used to score the paper to get crisp folds, you lay the needle over perhaps 30 degrees up from horizontal so the point does not scratch the ink.
  The fillet knife sharpener greatly extends the life of hobby blades.
  The little trowel looking tool is artist pallet knife, I use it to reach inside small sub assemblys to press down glue flaps well.

[attachimg=1]


The big 19 inch paper enlargement, I think 11x17 would be fine but by all means build in a size you like. I believe getting the flywheel to turn out nice will be the only difficulty, and the larger size may help with that part of build.

Post by: ShadetreeMotorcycle on July 09, 2021, 12:37:27 am
The Base:
In this enlargement, the base turns out nearly 9 1/2 inches long, even the 100# paper is floppy in this large size.
    This is my first time working with mat board, it is slightly thicker than 1/16 inch and The mat board liner really did The trick to stiffen the base.
The color is better than my photo shows as I have Very poor lighting, I hope to add a good light for better photos.

No feet yet, but holding shape well now, quite heavy as well with all the mat board added.


[attachimg=1]

What the underside looks like with the mat board reinforcement, I only went for about 96% coverage to save time, but you can get as fancy as you like here, you can even ad ribs as the mat board is thick enough for edge glueing.
 It takes me 3 passes to cut thru it with a used #11 hobby blade.

Post by: ShadetreeMotorcycle on July 09, 2021, 09:27:01 am
Update:

As this is an experimental build, I thought to try taking the reinforcement to the next level, I made a grid pattern of sorts out of 3/4" tall mat board ribs. I now can place a full gallon of milk on the base without stressing the base! This is overkill but fun to see what can be done. I believe milk is heavier than water.
  While the glue on the ribs was drying, I had the base weighted down to a glass cutting board I use as a work surface for paper model construction, this gave a VERY flat outcome, I very much want to run this engine on my aquarium pump and the crankshaft of this model has 4 bearing supports due to the turbine hidden inside the firehouse, I want all those bearings to stay in alignment for low drag.

The Ribs:

I looked it up and a USA gallon of milk weight approx 8.6 lbs

It would also make an interesting wall hanging. 🤠

Thanks for the explanation on the tools.  I was wondering what you used.

The wall hanging is a good idea, this art is old enough to possibly be considered historical. Simply pin to a hobby room wall would look good, but properly framed would look pretty fancy! :)

Hello Ben,

a really great build report. I have printed out the template in the meantime. Until my build starts, I will relax in my armchair and read your report, especially the improvements you make. So, as I build, I need not worry much about how any problems that arise will be solved. Just watch and read. Nice...  ;D

Thank you for the kind words, I think perhaps only you and txlabman are following my build thread, but that is enough to make it fun and worth while!
  I am only a beginner at paper card models, some take it to an art form, but as this model can be made to run, and stationary horizontal steam engines are my Favorite, so I don't mind putting my heart into this fun project. My goal is to get it to run on the quiet aquarium pump, but I believe if well built I may be able to step up to my airbrush pump and actually be able to power some of the smaller accessories, this will make the build more fun for me than simply constructing a display only model. I am happy to have you guys along for the journey.

Update:
Very little progress to report as I had to fix the wash machine today, however I thought I might share a couple paper model build tips.

The first is I highly recommend spraying your kit with some sort of clear art spray before you build, there are a couple of reasons for this, it adds a small amount of stiffness but the biggest reasons are it helps prevent warps in humid weather but even if you live in a dry climate, the BEST reason for the spray is when you make a sharp crisp 90 degree fold the surface of the paper often has tiny hair line cracks, (right on the fold line) these will show up white in color and the darker your model is, the more noticeable the cracks will look. These surface only cracks do not go thru the paper it is just the surface skin is separated from being stretched (you can try different size needle score tools to minimize this)
The fix for this is to run a color marker lightly along the crack and color it to match the ink on the artwork. Easy enough fix, but unfortunately un-treated paper will soak up the marker ink aggressively and bleed into the art possible giving a bad appearance. The treated paper bleeds very little or not at all so it helps a great deal.

The second tip is as you cut out your nice artwork paper parts the edges will be white so the model builder also "paints" the thin white edges with the appropriate color marker, this is just a simple swipe with the marker on the thin paper raw edge and goes Really fast but will make your finished model look twice as professional.
  Some guys get fancy and use watercolor colored pencils, these are special colored pencils with softer colored core and when you dip them in water you can kind of "paint" with them, the advantage is if you don't have the perfect color match you can blend with 2 or more pencils to get a really great match. (I just use markers)
  A more simple approach is on models that are supposed to look old you can just repair the cracks with some shade of grey! If you go back to the early posts and study the model built by thumb dog you will see he has a grey shade on almost all the edges even if  there was cracks to hide or not, this gives the effect of shadows and age but it really helps not having to match a color perfectly.

I have my base up on feet now but if you zoom the front of base the fold just over the word "vapor" along the front has a white crack I have not colored yet, this one is small but they can be quite large.

This is the spray I started off with but I am not recommend this brand, it protects well but anything more than a single light to medium coat will start to make the art look cloudy and if you really put to much on the art will look like a milk jug cloudy.
  The good stuff that museums and charcoal artists use to protect old documents and charcoal pencil art you can put several coats on and the protected work looks the same, you don't need several coats but you do not risk covering the artwork of the kit.

In the upper RH corner I have reinforced that foot with the mat board making it very strong, you can see I have colored the white edges that will show (on the foot) with black marker but grey would have looked good as well.
The loose kit part in the middle was supposed to have run on a 45 degree angle and closed in the corner foot, I choose to leave it off (More like a Wilesco) as the mat board has really made the corner strong.
  The other 3 corners need mat board yet, but I feel certain the base will still support the gallon of milk after the feet corners are all reinforced.
  The little Right triangle in the very corner just helps keep the L shape corner nice and square.

I posted the question about corner cracks to my paper model forum, a neat trick they told me is if you want to eliminate cracks, is just before you make your fold, you "paint" the back side of the part right where the fold will be with a q-tip soaked in rubbing alcohol, this temporary softens the paper and you make your fold, then the alcohol quickly drys and the paper gets hard again. This step is not necessary but may give a better looking model.

Update:
Finally back at the build table tonight, while the last 3 base feet have been reinforced and glue is drying, I wanted to make a good test of the alcohol trick to soften paper temporarily to make the folds.
  I had 2 identical spare parts and I used the same needle to scribe them, the one on left is alcohol treated and on right was dry folded.
  This is my Very first test fold and I noticed right away it took considerably less force to fold the alcohol treated paper! They both still have cracks but the alcohol treated is approx 80% better!
  The advice I got from paper forum suggested I was over scoring as well and I now believe this is true, I felt I needed a deep score as the 100# paper takes a good bit of force to fold, but now I feel with Alcohol I can use a 50% or even lighter score as the alcohol really helps. I believe with the lighter score the cracks will be 100% gone.
  I will start using this method for the rest of the build.

First test photo:

[attachimg=1]

Second test photo:
The new part on the far left was scribe with only 25% force of what I had been doing, I gave it about 3 fast swipes with Alcohol on back side and let alcohol soak in for 10 to 15 seconds and make fold....the alcohol is gone in under 1.5 minutes. The new test part has only 2 Tiny dots near center that the white shows thru, this is good enough for me but as I continue I am sure my technique will get better.

Here we have the base on its newly mat board reinforced legs, I only have 1/2 USA gallon of cream on it (this time) for weight as my gallon of milk is half gone.
  This test is actually more impressive to me as on the un-footed base the weight was resting on the internal ribs, in this test the center of the base is in free span....I really like working with the mat board.
   Also of note is the base does not rock at all on my counter top....I have a current production Wilesco D10 that requires a 1mm shim under one of its feet to be stable, I may have just got a bad one as other of my Wilesco engines have much more flat bases, but I feel that building on my glass cutting board has helped a great deal to get these results.

I wanted to take a break from the base, so I moved on to the boiler, it's worth cutting and folding one of the end caps first to make sure you glue up the boiler body to the correct diameter, my kit enlargement required me to overlap my glue joint nearly 2mm(extra) to get a tube that accurately match my end caps. The more you pre form your boiler tube, the better the outcome will be.

In the photo I have just wet out the glue flap with a rolling pin, but you can use a wood dowel, you are trying to avoid the glue flap being a flat spot on your tube.

Many thanks for the kind words, My Reward is just having a couple persons to chat with and share my build is fun for me.

Update:
I did make a mistake in my boiler build and I am happy to share so you may Not do the same! I was focus on getting the boiler body tube glued to match the diameter of the end caps really well, with my distractions I glued the "front" boiler cap to the "rear" of boiler....lol!
  If this was the "one and only" time I plan to build this model, I would simply reprint the boiler sheet and redo as cutting out the boiler only takes a couple minutes, however, I have to drive a few miles for print work AND I enjoy the challenge of trying to recover from my mistakes, the bottom half of the boiler is not colored the same as top because it is hidden inside the firehouse and this color scheme is supposed to help prevent the builder from doing just what I did, the simple fix is to "paint" about 1/4 inch of the boiler bottom that hangs out over the firebox door to get it to match. If I had my own printer I Would print a new part sheet. I will post photo of my mistake soon so you can see what Not to do. ;)

New build tip:

I have been using the large sewing needles to scribe fold lines but it occurred to me that I could easily be not holding them flat enough to avoid the point scratching the artwork, I asked paper forum what guys are using to scribe...a few use spent ball point pens but many do not like this option.
  A popular option is a tool I had never seen before.

Google "nail dotting tool"

it seems in the isle where fingernail polish is sold there are these tool sets of handles with small ball sphere on tip, a set will have several size ball tips, females apparently dip these tools in contrast colors to make round polka-dots and other art on there fingernails ::)
  The beauty is the ball shape tip is far less likely to damage your art, And you can test different size ball tips on your paper to get a fold to look how you like....the Down side to purchase these low cost tools is most paper model builders report there GF/Wife/significant "other" often swipe these tools right off your build table when you are not looking causing you to think you are loose your mind as the tool you just set down has vanished away....

[attachimg=1]


Here is my boiler so far, down near the table you can see the narrow strip of color that was to be the front, I had no marker that matched so I just used black marker(near top) this area will be in the shadow of boiler so perhaps it will not be such a problem.
  Also you may see some light color around the boiler end cap seam, I forgot to pre "paint" the edges before glue and marker does not color glue soaked paper well, the paper guys say the watercolor pencils do better, I just happen to have a set and when I find them I will touch up the boiler end cap.
  As 100# paper IS a wood product, you can also sand it, I find grit in the 400 to 600 range is best, if you go to course the paper will have a torn fuzzy look, I will dress up the boiler seam with 600 grit before the touch up color to get a smoother look.
