Title: Some recent work on the In-ko-pah RR
Post by: Ray Dunakin on June 28, 2017, 08:02:25 PM
I haven't had a lot of time for modeling so far this year, and what time I did have, has mostly been spent refurbishing older models. The newest structure is a through, plate girder bridge. Until now I've just had a crude temporary bridge made of wood, which has become badly warped:

 
(http://www.raydunakin.com/Site/IRR_Plate_Girder_Bridge_2_files/Media/IMG_2461c/IMG_2461c.jpg)

 

I built a permanent replacement for it. My previous plate girder bridges were all made using a structural fiberglass material called G10. This time, I wanted to try making it out of Sintra. I used 6mm Sintra for the deck and sides. The interior braces were made from 1mm Sintra. The rest of the details are styrene.  I got a bit lazy on this bridge and decided to leave off the rivets -- where it's located, no one can get very close to it anyway. The underside of the bridge is strengthened with three lengths of 1/2" square acrylic tube, plus three sections of extruded aluminum angle for good measure.

I sprayed it with red primer followed by gloss black. Then I weathered it with a thin, alcohol wash of gray acrylic paint. Then I used RustAll to create reddish rusty streaks. Next I used Sophisticated Finishes' "Iron" and "Rust Solution".

Two of my earliest structures on the layout were really starting to show their age. The paint was faded and worn (beyond the intentional weathering). The clear plastic used in some of the windows had yellowed, fogged, and warped. Slide cover glass used in a few places had broken or fallen out. A couple signs were faded, and both structures had minor damage caused by a raccoon. One of the buildings still had incandescent "grain of rice" bulbs, which I wanted to replace with LEDs. Here are the "before" photos:

Ray, Good to see that your models are salvageable! Sounds like you've been having a hot spell there and I saw photos of plastic siding and stuff over in Arizona that really warped and sagged in the heat there. The new bridge is a good addition to the RR.

Recently I've been working on a new building for the town of Mineral Ridge. This will be a saloon called "The Grizzly Bar". That's a double pun -- not only the obvious "bar/bear", but also there is a piece of mining equipment called a "grizzly" consisting of a series of thick metal bars used to separate oversized rocks from the rest of the ore.

Anyway, this saloon has to fit an odd-shaped space underneath a mine tram bridge. There will be a small covered porch or patio area attached to the main building. I'm not going to post a step-by-step at this time because I plan to use this build in a magazine article. But for now I will post a few in-progress pics:

I've set aside my model of the Grizzly Bar saloon for now, and started work on a new building for the Mineral Ridge mine and mill. This will be the power house. It will eventually contain a diesel-powered generator, an air compressor for the mine, and possibly a blacksmith's shop.

The major components (walls, roof, etc) are made from 6mm Sintra:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_0996c/IMG_0996c.jpg)



This is the main room. There will be a smaller room added on one side. The floor is 3mm Sintra, and won't be glued in until after I get the roof installed:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_0997c/IMG_0997c.jpg)

 
(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_0999c/IMG_0999c.jpg)



The smaller room was also made with 6mm Sintra. I use these steel machinist's blocks to keep everything square:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1021c/IMG_1021c.jpg)

 

Here, I've started adding the roof:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1023c/IMG_1023c.jpg)

 

There are openings on the rear of each room, for access to the interior. The rear walls will be removable:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1025c/IMG_1025c.jpg)

 

This is where the structure will sit on the layout:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1029c/IMG_1029c.jpg)



Fitting the roof of the side room into the roof of the larger room was a bit tricky. I used scraps of Sintra and some Dynaflex 230 paintable sealant to fill the gaps:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1034c/IMG_1034c.jpg)

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1041c/IMG_1041c.jpg)

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1040c/IMG_1040c.jpg)

 

Another shot of the structure temporarily placed on the layout:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1035/IMG_1035.jpg)

 

The smaller room will only have one window, located close to the cliff, so there is no need to detail the interior there. But the large room has multiple windows, making the interior fairly visible. The interior is built as a separate model that slides into the rear of the building. Because the exterior will be clad with corrugated metal, for the interior I am simulating the appearance of a a wood-framed structure. The interior walls are scribed to give it a little bit of a corrugated look. The framework is built up out of strips of styrene:

That's all for now. Enjoy!

Another good start, Ray! I know you've said this before, but can you remind me what you use to bond the styrene to the Sintra?

Bill, I use Weld-On 16. It's also sold under the "SciGrip" brand. It's for acrylics and most other plastics.

A little more progress on the power house...

 
I made the ceiling for the interior. It is detailed with rafters, and will be attached with screws so that I can remove it to access the interior:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1066c/IMG_1066c.jpg)

 
I also adding some frame detail to the inside of the front wall. This detail had to be carefully placed so it would line up with the removable interior:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1056/IMG_1056.jpg)

 
These shots through the side window shows how it all comes together:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1070c/IMG_1070c.jpg)

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1073/IMG_1073.jpg)


Next I started on the corrugated metal exterior. I had previously used real, galvanized, corrugated steel from Rainbow Ridge on my Assay Office building, and considered using it again on this one. But this building has more windows and also many more angles and joins, and the steel is difficult to cut or bend. So I went back to making my own corrugated metal out of .001" thick shim brass sheet. This comes in a 6" wide roll, and I cut into 4" x 6" sheets. I heat the sheets of brass with a plumber's torch to anneal them. Then I place each sheet between two pieces of the corrugated steel, and scribe the groove using a dull pencil:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1031c/IMG_1031c.jpg)


I start at one end, and scribe a short section at a time until I've gone more the half the length of the piece. Then I turn it around and start scribing the other end, and meet in the middle. Next I flip it over and scribe the other side. When it's done, I trim off that piece (about 1" wide), remove it, place the remaining brass in between the steel, and start over on the next piece. Tedious, but eventually I get it all done. The pieces of corrugated brass are then sprayed with oven cleaner to wash any residue off. After rinsing with water they are set out to dry.

I glue the corrugated metal to the structure using Dynaflex 230 paintable sealant. At this time I have completed covering the exterior walls and have just started on the roof:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1012c/IMG_1012c.jpg)


There is no need to apply metal to the rear walls, since they will be up against the cliff and not visible. In this photo the rear walls have been removed:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1025c_1/IMG_1025c_1.jpg)


Here are a couple shots showing how it will look on the layout:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1017/IMG_1017.jpg)

 

That's all for now.

So far about daunting projects :P. My suggestions comes too late, maybe you can try it another time: After annealing the brass sheet you may plate it with a tinning paste to achieve a base for a galvanized look. Some blackening fluid from a tiffany supply helpps to convert it to different stages of decay.
To be honest: You've driven your painting that much to perfection that for sure it will be easy for you to achieve those results without using chemicals.
Great work, Ray, as usual. It's a continuing pleasure to follow your work. Wish I could see it one day in person.

Cheers,
Volker

Before I can go any further with the building, I need to create the interior details. These will determine the locations of smokejacks, etc. I'm starting with the largest and most important item, the generator. This will be a "good enough" model -- something that will look good when seen through the windows -- rather than a precise scale model. I'm basing it on this diesel generator I photographed at the Diamond Tunnel mine in Eureka, NV:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_7323/IMG_7323.jpg)

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_7333/IMG_7333.jpg)

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_7338/IMG_7338.jpg)

 

I began by building up the "core" shape of the engine, using layers of 6mm and 3mm Sintra:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1077/IMG_1077.jpg)

 
A piece of 6mm Sintra was added at one end:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1080/IMG_1080.jpg)

 
I decided that the rectangular openings on the sides were a bit too small, so I cut a little off the top and one end to make the openings larger. The rounded top of the engine was made using a section cut from a 1" styrene tube:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1084c/IMG_1084c.jpg)


Then the sides were laminated with .020" styrene sheet. The styrene wrinkled slightly in a few places when the glue dried, so I filled in those spots with Squadron white putty and sanded it smooth:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1095c/IMG_1095c.jpg)

 

Next I added the arched extension at one end of the top of the engine. I also cut and sanded the top of the engine so that one side has a flat, angled surface, as on the prototype:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1106c/IMG_1106c.jpg)

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1108c/IMG_1108c.jpg)

 

The next step is adding the various shapes that protrude from the "core". I began with the piece seen in these two photos:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1113c/IMG_1113c.jpg)

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1115c/IMG_1115c.jpg)

 

And that's where it stands for now. More later!

I've made a little more progress on the diesel engine...


This part was made from a piece of 6mm Sintra mounted on a sheet of .020" thick styrene. The bolt heads were made from thin slices of hexagon rod:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1117c/IMG_1117c.jpg)

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1126c/IMG_1126c.jpg)

 
The plastic "pupils" from a set of cheap googly-eyes was just the right size for the disks on the side of the engine block:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1128c/IMG_1128c.jpg)

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1132c/IMG_1132c.jpg)


At this point I realized that I had made a mistake when I added the arch at the top of the engine. There is supposed to be an overhanging extension at the front of the engine block, with the arch on top of that. So I added the overhang, then extended the front of the arch, and cut some off the rear of the arch. Here's how it all looks so far:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1149c/IMG_1149c.jpg)

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1151c/IMG_1151c.jpg)

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1147c/IMG_1147c.jpg)

 
There are twenty small covers, plus ten large covers, on the engine, that look sort of like cookie jar lids. I've been trying to find an easy way to make them. Here's my first attempt. I think I'm on the right track, but this one is pretty rough. I'm going to try making another one, and if it turns out good enough, I'll try making a silicone mold and casting the rest of them:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1145c/IMG_1145c.jpg)

 

That's all for now. Enjoy!

I'm holding off on those covers for now, and doing something more fun. I started building up the thing that sticks out the front of the engine at the top. It's made of layers of Sintra with some styrene details:

First off, I found a pair of websites about restoring an engine almost identical to this one:

http://www.eldensengines.com/F-M%20Power%20Station/F-M%20Power%20Station.html (http://www.eldensengines.com/F-M%20Power%20Station/F-M%20Power%20Station.html)
 
http://www.coolspringpowermuseum.org/Exhibits.htm (http://www.coolspringpowermuseum.org/Exhibits.htm)


I learned a lot about the engine from from these two sites. For one thing, it's a 300 horsepower Fairbanks Morse opposed-piston engine, probably model 38F5-1/4. This type of engine has two crankshafts, one at the top and one at the bottom. It also has two sets of pistons, which face each other in the cylinders. Also, the large thing protruding from the top front, which I'm currently working on, is a supercharger.

In addition to powering generators, these types of engines were also used in locomotives, submarines, and surface ships.


Anyway, I've mostly been working on adding all the details to the supercharger. The air filter was made from a short segment of 5/8" styrene tube, with a piece of 1/2" tube stuck into it. An acrylic, elliptical dome was used to make the rounded bottom of the air filter (shown bottom up in this photo):

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1166c/IMG_1166c.jpg)

 
I cut another segment of 1/2" tube and cut a slit in it, so I could wrap it around the first tube. Later I cut a piece to fill the gap:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1169c/IMG_1169c.jpg)

 
A few years ago I bought some photoetched mesh with round holes, thinking I'd find a use for it eventually. It turned out to be perfect to replicate the mesh on the air filter:

I cut a strip of the brass mesh to the proper width, then wrapped it around a much narrower tube before installing it on the air filter. I sealed the ends together with tiny bit of thick CA, which was enough to hold it in place. Then I topped off the air filter with a styrene disk to represent the lid. I still need to add the bolt to the center of the lid:

Here's how it looks on the supercharger. I haven't glued it in place yet, it's just sitting there. The other details were made from various bits of styrene tubes and strips:

Here's the whole engine so far. The orange piece was made from the bottom of a prescription pill bottle:

An engine of this size and age most likely has its timing driven by a gear train which is inside because of its need to be lubricated at all times.

Russ:
A timing chain looks like a bicycle chain on Steroids. 
It connects the crankshaft with the top of the engine so the valves open and close "in time" with the motion of the pistons.  Most new cars have a timing belt which over time stretches and has to be replaced.  The last thing you want is for a valve to be open so a piston crashes into it as it speeds to the top of its motion.

If you keep learning one thing a day, your mind will never grow stale.
For Ray to allow you to see the chain, he's going to have to model the engine under repair with the cover off which is far to much work.

A few days ago I posted this photo of a styrene test piece for the covers on the engine:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1145c/IMG_1145c.jpg)


My plan was to make a rubber mold and cast these things in resin. But that test piece was too rough. Well, I tried a couple more and couldn't get it to look as good as I wanted. So I tried a different approach, making it out of 1mm Sintra and scribing the indentations. That turned out even worse:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1190c/IMG_1190c.jpg)


Even if I could have created a suitable master, I had doubts about how well such thin pieces would reproduce as castings. So I scrapped the whole idea and decided to come up with a non-prototypical design that would be simple enough that I could make all 20 of them individually. My first test of this was extremely simple, just a flat piece of styrene with rounded corners and a nut/washer in the middle:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1199c/IMG_1199c.jpg)


But I felt that this was TOO simple. I wanted something that looked a bit more interesting. The design I settled on was made by layering two pieces of .020" styrene. Both pieces had the corners rounded, and I beveled the edges of the smaller piece before gluing it on top of the base piece. Here's how they turned out:

After a very lengthy hiatus from modeling, I'm finally starting to get back into it a little. Currently I'm trying to finish up the two incomplete projects I'd been working on before. One of these is the Grizzly Bar saloon. I last worked on this almost a year ago. Here's where I left off:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_4_files/Media/IMG_0484c/IMG_0484c.jpg)


Since then I've painted and weathered the upper portion to look like old wood with faded/peeled paint. The corrugated metal was painted with two-part rust from Sophisticated Finishes. I also put corrugated metal on the roof of the patio. Signs were made by printing out the designs onto self-adhesive vinyl, which was then cut out as a stencil:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_4_files/Media/IMG_1295c/IMG_1295c.jpg)

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_4_files/Media/IMG_1338/IMG_1338.jpg)



Because the roof has warped a little, I had to curve the lettering slightly:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_4_files/Media/IMG_1306c/IMG_1306c.jpg)



The windows and doors were painted separately prior to installing the glass:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_4_files/Media/IMG_1311c/IMG_1311c.jpg)



I added security bars to the patio door. These were made from styrene:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_4_files/Media/IMG_1337/IMG_1337.jpg)



The building is now complete except for the lights and some interior details:

Really nice work! Glad to see you back at it again. Hopefully iíll Be off the disabled list soon. Detached retina in February, severL surgeries, laser treatments, and the most incredible pain Iíve ever experienced, I have another surgery this Wednesday that will hopefully take care of it all. One hard part is not having any depth perception, which for someone with Parkinsonís on heavy painkillers is not a good candidate to use sharp knives. So I putter a lot and you and Chuck and everyone else here inspire me to keep going ...

The other incomplete model that I'm trying to get finished is the power house for the Mineral Ridge mine and mill. When I last worked on it, I had been in the middle of constructing the large diesel generator for the interior. That part of the project is still on hold, but I'm currently working on finishing up the exterior of the structure. Here's what it looked like when I left off:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1033c/IMG_1033c.jpg)



I built two different smoke stacks for the building. One is for the generator and one for the blacksmith's forge. The generator stack is made of brass and has a conical cap:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1277c/IMG_1277c.jpg)

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1291c/IMG_1291c.jpg)



The forge stack is a bit shorter and has a simpler design:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1318c/IMG_1318c.jpg)



I also decided that the building really needed a pair of ventilation cupolas. I built these out of 6mm Sintra, with styrene strips for the louvers. Since I had already covered the roof with corrugated metal, I had to mount them to the metal with Dynaflex 230:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1317/IMG_1317.jpg)

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1313c/IMG_1313c.jpg)



That's about as far as I've got, for now.


Enjoy!

Looks good, Ray.


Title: Re: Some recent work on the In-ko-pah RR
Post by: Ray Dunakin on June 12, 2018, 10:13:01 PM
A little more progress...

Four strands of fine copper wire were soldered to the large smoke stack. The other ends of these wires were tied to tiny eye hooks, which I got from the jewelry section in Michael's:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_0358/IMG_0358.jpg)


I sprayed the entire exterior of the building with self-etching metal primer. Then I sprayed a bit of white primer onto the "wood" portions of the cupolas and trim:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_0352/IMG_0352.jpg)


I painted the doors and window frames, beginning with a coat of white primer. Next I applied various shades of brown and gray, to simulate the appearance of old wood. When that was dry, I liberally brushed on some Testor's enamel thinner. While this was wet, I added the white/green color coats, using a modified dry-brush technique. The enamel acts as a "resist", and this effect combined with the dry-brush technique results in a look of worn, peeled paint:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1355c/IMG_1355c.jpg)

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1356c/IMG_1356c.jpg)

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1357c/IMG_1357c.jpg)

 
I also painted the removable interior of the building's main room. It's a bit rough, but doesn't need to be perfect. Much of it will be obscured by the generator and other items, and most of it will only be visible from one angle when seen through the windows:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1360/IMG_1360.jpg)

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1361/IMG_1361.jpg)

 
The "wood" portions of the cupola and exterior trim were painted in a similar manner to the doors and windows:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1364/IMG_1364.jpg)

 
Then I had to mask off these areas in preparation for the next step. I will be spraying the building with Rustoleum "Cold Galvanizing Compound". This will give the building a realistic appearance of galvanized metal:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1368/IMG_1368.jpg)

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1369/IMG_1369.jpg)

 
That's all for now, more later. Enjoy!

I used this photo of the control panel at the Diamond Tunnel mine in Nevada to create the electrical control panel for the model:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_7331/IMG_7331.jpg)



I started by importing a copy of the photo into Photoshop, where I retouched it, cleaned it up, straightened it out, and cropped it. Then I printed it onto self-adhesive vinyl. I mounted this on 6mm Sintra. I also printed a second copy to use as a guide in making some details that would stand out in 3D. I mounted these on 1mm Sintra, and cut them out:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1371c/IMG_1371c.jpg)

 

I added some thicker pieces of Sintra as needed, and sanded them to shape. Then I glued the details to the main panel:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1373c/IMG_1373c.jpg)

 

Next I cut out the slots for the switch levers, and removed the remaining vinyl. I also added some dials made from slices of styrene rod:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1380c/IMG_1380c.jpg)

 

The switch levers were made from brass and glued in place:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1384c/IMG_1384c.jpg)



Next I made a frame for the control panel, using styrene strips and a piece of heavy brass screen:

(http://www.raydunakin.com/Site/IRR_Mineral_Ridge_Power_files/Media/IMG_1388c/IMG_1388c.jpg)

 

I painted the frame, and also painted the switches and other details to match the photographic print. Then I glued the control panel into the frame, and glued the entire assembly into the building's interior:
