A possible scratch build project for richotrain.
Posted by "JaBear" on Sunday, October 26, 2014 6:42 AM
Like a bear in a china shop I have taken the liberty of starting this thread as the topic was starting to occupy a lot of space here ....  
                       
... and I believe is worthy of its own thread any way. I just hope Rich doesn’t mind and also that others might contribute their valuable insights, or  methods.
Rich posted this picture...
... and posed the question, “How would you go about scratch building this structure?” to which there have been a couple of good answers.
The building foot print is as follows, the single story section was 474’ long, the two story section 288’ long, and both 60’ wide.
Converted to HO scale that would mean a combined foot print of 105.20”x 8.30”. Rich indicated that he was looking at the building occupying an area of 52” x 4”, and that the building should appear as it was in its heyday in the 1950s.
.Rich has not indicated, or been asked, how close to the prototypical dimensions, apart from the actual shortening of the building, he wishes to stick to, I am referring to door, window size and the like.
If he was wishing to be accurate then I’d suggest that he look for a better photo, or even plans, if the appropriate historical society had them, but I’ve made do with the photo supplied, and am working on the “Looks about right” principle.
So I am making the presumption that Rich would use as many available detail parts as possible, rather than scratch building the lot. (If the freight to this part of the world wasn’t so expensive, I certainly would.)
The first thing I did was draw the dimensions of the available doors and windows on the top left of the initial drawing, then with a 6” rule, MkI eyeball, and a reasonable amount of guesstimation came up with the following.
Looking at the photo, there is a repeated pattern of six panels, presumably the same along the whole bottom story, and I’m also presuming that the top story panel is replicated along its length. The dimensions I’ve come up with for one 6 panel section is smaller than the prototype, the single story having five 6 panel sections for its 474” length, whereas five of my 6 panel sections would only be 340” long. The apparent scale compression is purely accidental on my part, though i should shut up and claim it was my great ability.
Anyhow if I was using my drawing, I would use 2 of the two story 6 panel sections and 3 of the 6 panel single story sections which would give a building length of 46.25”
From the photo I just could not tell what those arched opening actually were,  are they single doors or have they been boarded up. Either way I couldn’t find an available commercial door that suited, and have drawn double doors with a curved transom window above just because I liked the idea.
Even though I omitted the awning for clarity, on reflection I may, if it has too great an angle, be cutting it a little fine.
That’s more than enough from me at this time,

Cheers, the Bear.

Bear,

I could see building one of the six-units sections as a master, then making a mold from it and casting the sections in plaster. It a pretty forgiving and cheap method. The master could even be made by hacking up suitable brick building sides from DPM or made up of the Walthers (IIRC, these have been discontinued??) or other modular walls.

I agree that the ~4' long compressed version you calculated should be big enough to be as impressive as the original. Of course, once Rich has a mold, it would be easy to make it even longer.

Wow, where do I start?

First of all, I am most appreciative that JaBear would start this new thread on my behalf.

Second of all, I feel a little bad that Frank and I inadvertently hijacked Steven Otte's thread as we waxed nostalgic about 1950's Chicago - - LOL.   No telling what repercussions may come from that!

Third of all, JaBear clearly captured the essence of those windows and drawers in his drawings.   Nicely done.

Fourth of all, Mike's suggestion to cast a mold is pure genius.  I never even thought of that.  What a money saver that would be.

I need to study this thread a little more, and I look forward to any further replies.

How long would one of those 6-panel molds be?  Might be a bit unwieldy at that size.

One of my backburner ideas is the PRR fruit terminal in Pittsburgh that's a staggering quarter of a mile long, but made up of dozens of the same 25ish foot panel.  A similiar endeavour.

I agree.  The more that I look at that photo, JaBear's drawings, and the DPM web site, the modulars seem to be the most well suited to this project.

I would like to learn more about casting molds though because the sheer cost of using DPM modulars to build this structure can be enormous.

Could I use one set of DPM modulars to make the molds and then go from there?

I am going to take the liberty of copying my post from Steven's thread to this thread:

Rich:

Neat structure!

I would suggest that this project would be better handled as a kitbash then a scratch build unless you are willing to forgo the arched brick over the windows. Personally, I think the arched brick is a key detail so I would want to have it on the model if it were mine.

As an aside, your structure could be built fairly accurately with Walthers Modulars but the cost for doing a building the size that you want would be pretty stiff, so forget that!

Frank's suggestion of the Walthers freight house is almost perfect for the upper story with the two windows/pilaster/two windows/pilaster pattern, and the arched brick over the windows. The windows aren't quite as tall as on the prototype but I think they would be plenty close enough. The trick would be to find a matching styrene brick sheet for the lower storey. If you can do that then you are away to the races. According to Walthers their brick sheets match the brick patterns on their Cornerstone brick structures.

http://www.walthers.com/exec/productinfo/933-3524

At first I thought that one Walthers freight house should provide you with all the upper story windows that you would need, assuming that the building will be seen from one side only. However upon closer examination it appears that the windows in the freight house are not all the same height so you may need two kits depending on how long you want the two storey section to be. I am also assuming that the Walthers freight house is the same on both sides. If you use the taller windows on the first floor and the middle windows from the end walls of the second floor you will get six panels of two windows and one pilaster, or two pilasters as will be needed for one end of the wall. Each panel is about 3" so if you want the two storey section of your freight house to be half of the 52" length of your project, then you will need either eight or nine window/wall panels to do the second storey. If you use just one kit your second storey will be about 18" - 19" long. Having the two storey section a bit shorter than the single storey actually seems to be in proportion to the prototype.

The large freight doors are a bit hard to see but the one that is fairly visible looks something like this:

http://www.walthers.com/exec/productinfo/120-2402

or this:

http://www.walthers.com/exec/productinfo/87-133

They would be reasonably easy to make using some V groove sheet and .010" x .060" strip, or there abouts.

The smaller arch top doors that are on either side of the larger doors could be a challenge, mainly because of the brick arch. You could get away with using styrene HO corrugated roofing with the corrugations mounted horizontally to simulate roll up doors.

The foundation looks to be plain smooth concrete. That's easy to do.

The docks can be made from V groove styrene sheet to simulate the wood boards, but I question whether or not they should be modelled at all. It looks to me that originally there were no outside docks and the track would have been right beside the walls. The docks in the picture appear to have been added later. I suspect this because first, there is no evidence of attachment points for either docks or roofs on the rest of the building, and second, the docks are warped. If they were original to the building they would have been built better than that. At least that's my theory and I am sticking to it!Smile, Wink & Grin

The sloped roof on the single storey section appears to be covered with some sort of panels, although the size and orientation is different from a typical corrugated roof. The panels appear to run horizontally instead of the usual vertical mounting and they appear to be quite a bit larger than typical steel roof panelling. I would still go with corrugated styrene and use a #11 blade to lightly score the outlines of the individual panels. I would not go to the expense of installing actual corregated aluminum sheets. That would get expensive and unless you are fastideous with the installation you will end up with creases and bumps which are just plain not prototypical IMHO.

I would note the fire wall that shows on the roof. It is evidenced by the raised wall that runs vertically at about the middle of the two storey section. The fire wall would be solid all the way to the foundation with the exception of fire doors that would be closed in the event of a fire to stop it from spreading throughout the entire freight house. That is the sort of detail that adds a lot of visual interest.

I have a tendancy to go on forever so I will quit for now.

Dave

 EDIT:

I hadn't thought of the DPM walls. As others have said, they would be quite suitable.

Since I have done a lot of resin casting, I will try to give you a cost on materials. 

To cast this yourself, you are looking at a minimum of $120 in casting and mold making materials.  That doesn't include the masters (DPM parts), and whatever you will use for the roof materials.  What you would have to make is four different wall section molds, and four different window / door molds.  The wall sections can be cast from plaster, but the windows and doors should be cast in resin. 

But, if you make the master sections to include the windows and doors, you wouldn't have to make molds of the windows and doors.  The primary cost is the RTV needed to make the molds.  This is going to be $80 alone.  If you make the windos and doors as part of the walls, and cast them in plaster, then you are looking at the extra cost of the plaster and paint.  And plaster will be cheaper than plastic resin.

Elmer.

The above is my opinion, from an active and experienced Model Railroader in N scale and HO since 1961.

If I may, strictly as an observer, offer: I'd be reluctant to use the DPM parts even as a master.  Of course, now you have to make a master from...something else.  DPM parts look like DPM parts no matter what you do with them. I think it'd detract from the overall appeal of undertaking the duplication of such a large and unique structure.

One option is to slice and dice the DPM molds into something that resembles the prototype more closely. I don't think they probably have anything real similar, so presumed some modification would be needed anyway. In the end, most people will have a convincing view of the bulk and repetition of the structure. The few who wnat to argue details should just be congratulated and then you can launch into a lengthy description of how much trouble it was to just get close-enough that they may be able to appreciate why you didn't handcarve the whole thing from a ginat block of balsa wood...or maybe not, sometimes that's how those folks just areHmmWink

As for the size of the mold, I'm thinking ~12" wide, which is not super large. On the other hand, splitting it into two different molds would be no problem at all and would make it easier to handle.

Yeah I'd figured something like taking brick stock and laminating it to a thinner backing of styrene.  That'd let you control the distance between the pilasters, the size, and so on in a way that DPM panels don't let you.

That's pretty impressive.  It looks like it beats the B&O's warehouse in Cincy for length, but the one in Cincy is five stories tall.  What it lacks in length, it makes up in floor space.

I just may.  With the golf season fast coming to an end in the Chicago area, this could be my first winter project.

With the DPM Modulars though, it will be more like kit building than scratch building.  Oh well.

The hardest part about scratch building that structure, will be cutting out all the windows and doors. So start looking into some good cutting tools, like inside corner cutting punches and such.

Frank made this comment in that thread started by Steven Otte.

If I were to scratch build this structure using brick sheets and Tichy windows and doors, as suggested by JaBear, does anyone have some specific suggestions on the tools needed to do this project cleanly and efficiently?

It was rather late last night when I posted this and while I mentioned my 6 inch rule, MkI eyeball, and guesstimation, I see I neglected to mention my scale rule, HO scale man and 40’ Athearn BB boxcar, the latter two being valuable as visual cues to help me keep a sense of proportion while drawing plans.
Thanks to everyone for all the input so far, as hon30critter has reminded us, “More than one way to skin a cat.” (BTW, pleased to see you move your post to here Dave, I felt a little guilty opening this thread and leaving your good ideas behind.)
 Mike L, I certainly wouldn’t have thought of making plaster casts, though if I go down the road of building modules to go to shows, the weight and strength would probably preclude me from using this method. Having admired HO-Velo Peters work on his Downtown Deco back drop building in recent WPFs, the idea certainly has merit.
Nittany Lion. A six panel double story section would be 9.50 x 4.30 inches, how manageable that would be to work with; I’ll leave to those who know what they’re talking about.
I was about to make a complete prat out of myself and ask if your building was serviced by rail but on closer inspection I’m presuming there was a spur that ran off  the appropriately named “Railroad Street” somewhere around 23rd Street. Boy!!, Google Street view is a good tool for us out of towners. A direct side on view is certainly a lot better to scale from.
I certainly agree with your comments, “.... DPM parts look like DPM parts no matter what you do with them. I think it'd detract from the overall appeal of undertaking the duplication of such a large and unique structure”.However sometimes a man has to do what a man has to do, and with an application of imagination they would be a useful donor parts for a mould.
 “How in the world do those trailers manage to back in, and then get out?
Steve S, Frank would be able to tell you for sure, but I guess you’d have seen some pretty impressive driving skills especially their ability to “jack-knife a trailer into a confined space.
 I was holding back so as to let others have their say regarding construction methods, but my approach would be to use 3mm MDF, card stock, brick paper, preferably embossed though it’s not cheap, and go through the time consuming and, to be fair,  laborious task of scratch Building the lot.
However I have seen doctorwayne mention that 8 x 4 foot sheets of .060” (??) styrene can be purchased over there, and for a reasonable price.

JaBear, great follow-up reply and timely since I was researching the Internet this morning on scratchbuilding ideas.

The more that I think about it, the more that I agree with you that the DPM Modulars are, perhaps, the easy way out.   With the proper tools and materials, I think that I could do a much more prototypical project if I scratch built it with styrene plastic walls and Tichy windows and doors. 

I am tempted to start yet another thread to get ideas on the necessary tools and materials.  For example, would you scratch build the walls out of smooth styrene plastic and, if so, how would you scribe the bricks?

My tempation is to scratch build this structure.

If using styrene, and as long as the cutting jaws weren’t too big, a tool like this could make cutting all those openings easier.

I’d suggest that you keep everything in one place, a Compendium of Scratch building, so to speak.
What does Plastruct or Evergreen have to offer?
And as pm is about to turn to am, and with the rain on the roof making a soothing sound I’ll bid you adieu.

Rich,

It's very hard to tell someone how to build a house, that has not built a wall before. Almost exactly how You would scratch build a miniature building....but you start from the outside in, not inside out like a house. What I mean by that. A flat embossed brick styrene sheet, you would cut all the windows/door openings first, then add framing to the inside, butt the sections together and continue your framing on the inside, throughout its length a width. The base should be one solid piece that fits inside your building that you add your walls to. Like example, 1x6 #1 grade Pine the length and width of your model and build your building around it. Your dock doors, some open will look like you have a concrete foundation inside and will match the height of boxcar doors and trailer doors. I know because that's how I do it. You can use a good piece of plywood for that also. Very solid support that way, when I put my on the layout, I screw them to it, just a couple of small wood screws. If I want to move it, just take the screws out, disconnect the light plug and take it to the work bench, if You want. I suggested using the Walthers freight house, because it's in scale, windows are similar and can be used as a template for the freight side for the windows and doors and just keep making the sections along the length. Like I said, a lot of cutting of doors a windows. Browse Micromark scratch building styrene/wood cutting tools,inside corner punches, for windows and doors. Will be much faster/easier with them. When I get a chance today, I'll find them. But nothing stopping You from looking. Also take a look at all the scratch building supplies that Hobbylinc carry's, brick sheets, some up to 24'' in length 6'' wide .020'' different sizes/thickness's, plastruct shapes/evergreen. That is one of the best places I have found for many things, a lot cheaper than a lot of on line stores. I use them a lot:

Steve S.

The trailers that You see in the pic, most are being unloaded. They are there 4 to 5 am. the smaller trucks are picking up. There all probably 30 different produce/fruit seller suppliers in there.selling their brand. By the time the larger trucks are empty,it is easy to get out again. Around 2 in the afternoon. I worked there part time, some times after my full-time job. All union Teamsters.

Take Care!

Frank

Btw: Ever see the movie Hoffa? Watch it. Produce market...before being unionized. Most all that movie, is true story.
