CHATTANOOGA CAR SHED - UPDATE

Latest photos show the completion of three walls. In a prior post on the shed, I mentioned that I used Chooch flex wall and Micro-Mark Factory Red Brick adhesive paper. These were formed over the base wall made from a double layer of plywood to get a good thickness for strength. You will notice one wall has the limestone pillars painted a light gray. This was a test that I found very satisfactory. It is a medium wash using a craft paint named FOG from Michaels art supply. 

 
Next was to create a jig to build the trusses / roof supports as seen below. I used the upper edge of the end wall as the guide to place #18x5/8" wire brads. The jig base is  left over piece of pine. The trusses are Pastruct #90655. First was to cut off the one beam in order to get it to flex then removed one of the remaining V sections from each end. So far I have 8 completed with two more to build. Next will be constructing the roof; I plan on using Evergreen sheet styrene, part #4250, V groove .040" thick. Each section is 6"x12". Amazingly, the foot print I made was perfect such that I did not need to cut to fit any section. Four sections laid side to side fit perfect!
Fast forward... creating the jig is usually the biggest challenge and that was no different for the roof. But how to get the .040 styrene to bend and hold its bend was a conundrum. A few conversations later with friends, they suggested a heat gun. But I needed a solid base to allow the styrene a solid base to reform.  So a small jig was built. Scrap 3/4" particle board was cut into arches in line with the ends of the car shed to accommodate one section of styrene. Aluminum flashing was to be the solid base and secured to the arches. 


Anchoring one end of the styrene with clamps, I moved the heat gun over the surface until the plastic began to relax. One great idea from Ray Russel to help hold the new shape was to place a cold towel immediately onto the styrene to lock the position. In the end and although it came out reasonably well, the problem was that I could not count on each styrene section to remold itself into an exact position so that all 5 sections would line up cleanly. I need to be bale to have a solid even arch base to shape these .040 sections. Why .040? Because they have the V grooves far enough apart to replicate the solder joints shown in the photos!
Sharing my dilemma with club members, Steve Lang suggested taking two .020 sheets, glue them in the shape of the arch and that could serve as a sub roof to hold the .040 sections in the arched position. "But Evergreen doesn't make them 1'x2'." Steve did have sheets that size - exactly! Love how a plan can come together.
Starting with old 3/4" plywood you can see I cut 8 arches and secured to a base. 
I was unsure how to clamp the roof and then the duh moment... 
add spacers.
 JB Weld epoxy was my choice to secure the aluminum; speaking of which, it was also the exact size needed when purchased, 1'x2'. Very happy several materials were ready to use.
 Here is the jig with the sub-roof being prepped, limed up.. 

The two .020 sheets were lined up on the aluminum and clamped. Leaving one side clamped, the other side was opened in order to apply the Ambroid PRO-WELD. I went to a much larger brush and wider container since the accompanying brush was way too small when I needed to get a lot on quickly. But it worked.
So far so good. However there was a slight uplift to the sides of the sub-roof. I am hoping that by clamping the V groove sections onto the sub-roof using JB, and onto the aluminum jig to hold the curve, the end result will be close if not spot on.
First is to line up the V groove styrene sections.
 One edge was then secured with clamps to hold the position.
JB Kwik (5 minute epoxy) was applied to the other edge. After that hardened, waiting about 1 hour to cure, three more applications with hardening time has one section secured. Below two sections are in place. The other two sections are place holders to ensure alignment.

Chattanooga Car Shed

Chattanooga is an end point on my W&A line. One of the 'signature' elements is the relatively much photographed train station. At that time these structures were called the 'Car Shed'. It is a term used in larger cities along the W&A such as Atlanta and Dalton. However, the smaller towns depots and stations were usually constructed of brick or field stone. My challenge was to find a material that replicated the limestone pillars as seen in the photo below...
Finding no textured material, I did locate a paper product of limestone block from Miniature Planet. However, when I went to purchase this they had discontinued that particular design... figures. I had used a flex wall for another project manufactured by Chooch. Problem  was that it did not bend on tight corners as needed for these small pillars. Fast forward to a couple of weeks ago when I took my first trip to the incredible Springfield train show. Speaking of which, it was well worth the trip from NJ. But that's another story. Fortunately I met the owners of Chooch. Their idea was to score the corner to make a clean bend at the tight corners. He also suggested how to alter its color with a gray wash. I purchased the HO/N Small Cut Stone, #8260, and found it to work fabulously! The scoring idea was perfect and it took the wash remarkably well.
Here is a sequence of pics from package to install... 

The wall starts out 4"x24". It is very easily cut with an Xacto #11 blade or a single edge razor. Most important of course is to accurately measure and mark the corner for scoring. I used ply bass wood as the frame. While scoring the flex wall I accidentally cut all the way through the Chooch wall but not the backing material. But that was not an issue. These walls have an adhesive backing and stick very well. In some cases I used hot glue because then narrow sections did not adhere well and the hot glue worked fabulously. I also decided to clamp the interiors to ensure adhesion. 
Below is the sample of how the walls will look once assembled. Next is to tackle roof construction. More on that later.

Organizing Tips 1 - Styrene Sheets

I cannot emphasize the pleasure of having my 'stuff' situated for ease of access. I, as perhaps many of you, have acquired many different styles and diverse sheets of styrene. In the earlier days I was experimenting scratch building everything from structures to rolling stock. I had used both wood and styrene to find what I prefer given the different advantages and challenges of each. Researching the different master modelers' ideas, often recommended was to have on hand a wide variety of materials to avoid time lost either traveling to the hobby shop or waiting for the mail from on-line purchases. Inevitably I would need something that I did not have on hand. My conundrum was how to organize the packages which were in a box and required a constant rifling through to find what I needed. Here is one solution that you may find useful. This is a left over large 3-ring binder from training materials for my work. Staples provided the plastic inserts and wallah! I had my organizer!
 
Seeing this as a viable way to hold and organize, also filed were all the various paper products from Miniature Plant. I was going to add their link here, however, it appears that they no longer exist as their name is up for sale! This is one most important reason that if you find something you like, PURCHASE EXTRAS! This company was fabulous because you could purchase a sheet, download the PDF and print as many sheets as needed.
However, the general idea of using a binder is something to consider as you look to become organized. Hope you find this helpful.

Organizing Tips 2 - Building Sheets and Scale Lumber

If you follow my blog you know that the majority of buildings are scratch built. This requires a variety of styrene as well as scale lumber materials. At the very least, if not organized, looking for what I or my crew need is cumbersome and an inefficient use of time. At worst it is very frustrating combing through boxes or piles of packages. Keeping building materials organized is key to expedite ease and efficiency. I had a common situation, as many model railroaders, limited storage and wall space, especially since the ceiling is cathedral-like and at an angle. Here is one idea I came up with to separate the building materials. It is a file box with eight sections, four on both sides.
On the left half or section of this filer I have inserted both styrene and paper walls, roof and flooring materials. They are organized in large zip locks.
As you can see, each zip lock is labeled. Others include Shingles and Roofing. This makes the 'search' effortless. On the right side or section I insert the variety of Northeastern, Midwest Scale Lumber and Evergreen Styrene Strip material. 
Above these packages of scale lumber and styrene strips I filed thick styrene sheets. The file box is thick plastic and easily attached to the wall. These can be purchased from Staples or other office supply houses.

Turnbale Discussions Episode 4, Part 1

July 2016 I had the great pleasure to be with Charlie Taylor at his Memphis and Charleston RR. Charlie has been working diligently in preparation for our American Civil War RR's 2016 meet in Memphis. He chose O scale acquiring equipment from SMR and BTS. Track is all hand laid by Charlie and turnouts were built using FastTracks templates. The line runs from Memphis and includes the towns of Huntsville, Corinth, and Chattanooga. Also featured is the "Lost Tunnel" recently located out side of Chattanooga by Charlie and Mark Brainard, an ACW RR historian. Three of the most outstanding features by Charlie are the scratch built trestles and bridges. The structures are of the most beautifully constructed by his friend CC (Charles Curro) who has evolved into a master builder in his own right. His head is slightly visible in the background. Charlie's nephew, Will Shirey, is the gifted artist who painted the backdrops. Will's art here was a key element of his portfolio that got him an acceptance into a premier art school in California. 
This is a brief 'interview' with Charlie Taylor in his layout room. Charlie, by the way, was a bit reluctant to do a more in-depth, formal interview so we took what we could get.You can see more photos of Charlie's layout. Go to "Labels" on right side of the blog. Click on Memphis and Charleston RR.
