Title: side dump hopper
Post by: GD on June 16, 2010, 12:32:43 PM
Hi,
Since I am new to this forum, I will introduce myself shortly. My name is Gerard, 45 years, married and 4 kids and I live in a small town near Goude, in the province South Holland, The Netherlands. Since I am rather space starved, my modelling tends to be British-style: small layouts with some fiddle space. Recently I ripped my permanent lay out to start something new, German railroads era 3. Apart from that I have some Dutch rolling stock, early nineteen seventies and some Dutch stock from the last 5 years and Swiss metre gauge Rhatian Railway. All waiting for a project. I must admit most of my modelling is `start a project and never finish it´. Aslo, progress is always very slow (job, kids).
Last year I bought by some On30 stock at my local shop, a shay and some cars. I am building a small diorama aprx. 2 feet 10 inch x 1 foot. I now would like to start scratchbuilding some hoppers. On the website of the Terrapin narrow gauge society I found drawings by Mark Reusser of a side dump hopper which seems to me as a good project to start with. Since the drawing has no indications about the size of the hopper, wether it rode on trucks or just had 2 axles etc., could anybody please give me some more information about this hopper. And am I correct by assuming that the hopper was unloaded by pulling out (by hand) the long sideboad.

Kind regards,

Gerard

Welcome to the forum Gerard,

I saw your project on the Dutch rail website, and wanted to make some comments, and post some info, but I am not a member there, and my Dutch language skills are non-existent. ;) ;D

These drawings were done for a "Model Challenge" by  Light Iron Digest in Sept/Oct. 2005 ....where the editor found a photo of this car, and published a photo or two, and the challenge was to build the car as a model......My drwaings were extrapolated from those images...but merely show the wood shell construction, they lack all the hardware and unloading mechanism. (at the time the drawings were done fome me only, so I could extrapolate some 2D plans to work from (the hardware didn't require plans for me to do, so was not included). At the time neither the magazine editor nor I really knew the use and details of this type of car.....but I have since then run across a PDF catalog file  that shows these cars and how they were used, built and functioned.

I will pull scan the original photos from the magazine, and try to find the catalog on my HD to pull some images/info from for you.  (give me a little bit of time though......digging through my files and finding something , especially on my external drives, is like trying to find Dr. Livingstone in deepest darkest Africa. :) )

The answers for now though are:

The hoppers wer not opened by use of the boards....they were operated mechanically, or manually by wheel/lever there was a eccentric arm and rods at the end, connected to those boards, that pushed the sides open. Those boards also had "tension rods" running across the oustide of them.

The photos of the car showed no trucgs or wheel whatsoever, but if I recall corrctly, the catalog shows them as being 4-wheel cars...as I am sure you have noticed, trucks dont turn/function well with the construction system of the car....there were axle bearing blocks mounted on the long sills under the hoppper, and the wheels were just outside of those sills. (Hope this makes sense).

When I find the info I will post it here in this thread

For others here wondering what the heck car we are speaking about, the drawings are here:

PS. Gerard,  if you are interested, at the time I started a model of the car (only the wood parts are done/assembled)...but I can take a pic or two and post it as well.

So I take it that the reason most Dutch people speak English is because their own language reads like gobbledy gook and even they don't understand it ?!?  A bit like Welsh .

  I can cope , just about ,with a bit of German and French , but Dutch really is a language to far . Still someone has got to speak it , so it might as well be those people who live in Holland .

  At the end of all that , welcome to the forum , Gerard . Though how you can have time for modelling with four kids is beyond me .

Yeah...and I thought Swiss German was a "throat sickness" of a language...but it's nothing compared to Dutch. ;D Even with all the languages I can muddle through, this is one that really escapes me...I can't seem to find any real "reference points" to work off of when reading it.  :-\ :)......but they do turn out some mighty fine model builders ;D ;D

They also make nice chocolate, beer, cheese, various other goodies, and have a swell neighborhood in Amsterdam where you can find all kinds of functional models! -- Russ

Welcome Gerard.

I've been watching to current Tour de Suisse coverage in Dutch sometimes. It's a lot more soothing than the Italian coverage!

Marc, please let's see more details of that car. I need ideas of what to build for my 1:13.7 line off the patio. Looks like a job for some hard pine and the table saw. Is your sketch based on a prototype of some sort?

Thanks, John

Hi Gerald,
I believe that the car you are refering to is made by C W Hunt.  I posted a pdf of the catalog on my website at:

http://www.narrowgaugechaos.com/RPC/Material/IndustRREquip/CWHunt/CWHuntIndex.htm
Look for the Industrial Railway - Cat 38.  The car is featured about halfway into the catalog.

The general website is at http://www.narrowgaugechaos.com  and has some other catalogs that maybe of interest.  More to post just need to scan ...
Marc I would love to see some photos of your model.
Cheers,
Marty J

Hi all,
Thanks for your kind words and advises. Since it is now 7.30 am and I a.m. and I just arrived at work just this quick reply. Marc, thanks for your offer. Take your time, as I said, modelling goes on a slow pace and since I am not very technically skilled, I often need a lot of time to think things through. That will also be the case for this hopper. I will post a more substantial reply later today.

Kind regards,

Gerard

Gerard,

I found my old file on this project with some images I took back then in 2005.

I did the drawings and model before I found out about Marty's catalog of these, so all my information was extrapolated from the photos shown on the magazine page.


Going back and looking at the images again today, I noticed that this car must have had 4-wheel trucks at each end...at least in its last use before abandonment, because in the underside photo you can clearly see the bolster skid plates, as well as where the now missing truck/bolster bearing plate thing, used to be.

Some pics of the stryrene build in progress. My build scale on this was 1/32  (No standard styrene sizes were used, all the planks were laminated together out of multiple/various sizes of styrene to get the proper size needed)

These last two images show the painting in progress....and it is pretty much where it still stands today.  ::)

How disappointing. You suck us in with a superb start, then leave us frustrated with modellus interruptus. Go stand in the corner. -- ssuR

Hello,
Marc, thank you for the drawings and the pictures, I think they will help me a lot. Marty J. thanks for the link, alas I am not able to open it, I will try to figure out why it won't work. Jacq, Marc already answered you, I am also an infrequent poster on beneluxspoor.net (www.beneluxspoor.net). If you are interested in some of my topics, type in the search box (zoeken in Dutch) Hüllendorf (my previous layout, trashed), or Zwammerdam (Dutch winterdiorama, already trashed), Small yard (my On30 with a temporary name which seems to remain forever) or stoffige dozen (dusty boxes with unfinnished projects). Of course they are all in Dutch, please don't break your tongue ;)
Below some pictures of small yard. Structures are made from cardboard, old cerealboxes and baby milkpowder boxes. Trees are from multistranded copperwire, twisted in shape and soldered together. Also a picture of a cardboard mockup of the hopper as I estimated it would be. It seems a bit too big with an estimated length of 15 feet.

Regards,

Gerard

Someone sent me this link, cuz it shows some little wood side-dump hoppers that are quite similar to the Mann's Creek cars I make in On30:

http://digarch.lib.mtu.edu/showbib.aspx?bib_id=642813#

Haven't done any further searching yet to find out more .... but looks like it might be worthwhile to do that.

Edit:  The railway is in Spitsbergen, Norway ... if someone knows the Norwegian word for "railway" that might help refine the search.  Meanwhile:

I reject your corner!...on the basis of unsound reasoning! ;D ;D

On second thought I may just use the corner to hide in shame.....it's really kind of tough/embarasssing to drag out 6 year old work, that wasn't done that well at the time, and certainly isn't up to the level I shooting for nowadays. ::) :-\

That's the problem with the web...it's like a big pool...once you pee in it, you can never get it all out again. ;D

John --

Sorry, but no ... the Mann's Creek book has a very simplistic set of drawings (side and end views only) and a handful of photos, so I interpolated things a bit ... the frame is a very basic pedestal design.  My version looks like this:

Hi all,
It's been a few days since my last post. I have been pondering how to tackle this project. First of all, what material to use. I think I have a go at cardboard for the body and wood for the underframe. The cardboard mock up I made doesn't look too bad and I like the material. Since the underframe has to hold the trucks with a screw (I suppose), wood seems better to me. Next I have to make a list with parts I need and find out if I can get them at my local shop. They do have quite a lot of American stuff, so I might be lucky. In the meantime I also want to make some progress on my other modelling and study this forum for tips and tricks, it's very helpfull.
@ Dallas, railroad is "jernbane" in Norwegian (according to an online dictionary).

See you,

Gerard

Hello,
Been away on a holiday for two weeks, but picked op modelling again this week. I decided to have a go in styrene. I now have a body almost ready, although slightly inaccurate. I found out I misunderstood Marc's description of the car as far as weels are concerned. So now I am stuck with two trucks. New project :)? Marc, do I understand you correctly if I conclude that the axle bearing blocks are like an "inside frame", rather than the axles sticking out beyond the wheels and running in axleboxes that are hung in W-irons of some sort?

regards,

Gerard

Hi everybody,
I posted some pictures here yesterday, but they have disappeared. So, next try. I also started work on 3 more hoppers, to make up a short train. I could not resist painting the model already. I used "wood" from model masters, but the car looks like it came from the shops just recently. I have to dull the paint down. Mayby I will try some "field drab" on top of the wood-colour.

Regards,

Gerard

Hi everybody,
No progress  :(. I got stuck with the underframe. I succeeded in opening the catalog Marty added on page 1. As far as I can see, all cars by Hunt had axle blocks. If I follow the drawings, this will be a problem for the cars are 3 feet gauge, and On3 isn't. I think..... While writing this a possible solution popped up, if I can find a good set of wheels... OK, Iwon't bother you with this one. I am also not very saisfied with the colours on the painted parts. I need to tone down the wood colour to a more grey-ish colour. Modelling time is also scarce again, I have a boss to keep satisfied, and there is this other layout. So, it might be a while before I can give you an update.

Regards,

Gerard

Parts such axle blocks, journals, pedestals- these are all good candidates for resin casting. Especially if modeled first in 3D CAD and then rapid prototyped via PAP. It is another thing on my many back burners- 1:13.7 car parts and 1:48 4-axle parts.

Do pray tell, what is a Hunt axle block? Any photos or drawings? Sounds British to me.

John
Title: Re: side dump hopper
Post by: GD on August 23, 2010, 01:57:25 AM
John,
Hunt is the firm that (probably) made these hoppers. Earlier in this topic there is a post by Marty, and he included a pdf of a catalog by Hunt. I assume they produced their own axle bearing blocks for the rolling stock they produced. 3D CAD, resin casting etc. are way beyond my skills and possibilities. I have to scrtachbuild the whole stuff from styrene and/or other materials.

Hi everybody,
It's been a while since my last post. My side dump hopper project grinded to a halt shortly after my last post. I got distracted by work, kids and a h0 RTR inglenook (the progress on wich is just a little less slow). Last week I tried to work out my idea. I simply laminated sheet styrene, the outer layers a few mm longer than the inner. I used an old set of roco-wheels. I filed off the point of the axles, to get stub axles. I must admit that it works, but I am not satisfied yet. I think a massive block with the wheels protruding left and right somehow does not feel prototipical. I can't make out very well from the pictures in Marty's pdf how they should look. I also used kadee knuckle couplers, but I don't like the look off it. A link and pin probably looks better on a car as this one. I hope to post a picture in the near future.

Regards,

Gerard
