In-ko-pah RR: The Princess Shilo Mine

Modeling
#1

I’ve started on a new mine for the layout which will be named after our oldest grand-daughter. The Princess Shilo Mine will be located in a prominent position on the southwest corner of the layout. The mine will be on the hillside, with an ore bin that straddles the track:

I liked the look of the Great Western Mine in Gold Point, NV. The Princess Shilo Mine will be a different design, but will retain the same basic features: a wooden headframe with a riveted steel ore bin:

I made the ore bin from a 6" ABS tube and matching cone, from Plastruct. I filed the tip of a nail to a rounded point and used it to emboss rivets into sheets of .010" thick styrene. These were laminated to the exterior:

Some of the embossed rivets were damaged by the solvent adhesive, so I applied tiny drops of 3D fabric paint in their place. This worked reasonably well. The larger rivets are from Tichy Train Group, and are individually applied in drilled holes:

The ore chute and gates were a bit of a puzzle. The Gold Point prototype didn’t have any that I could see in the photos. I found pics of other mines with similar ore bins but no close ups of the gates. I eventually settled on something loosely based on the discharge gates of a concrete skip.

I began by building a square box of .040" thick styrene, and cutting arches out of the bottom edges to fit the cone. Then I cut the other end to the necessary double-curve shape, and gradually built up the gates. When finished and installed, a lever will be attached for opening the gates – though they don’t actually work:

The complete bin with a coat of red primer. Eventually it will be painted to resemble rusted steel:

The wooden support structure was another puzzle. Unlike the mine in Gold Point, this ore bin must straddle the track to load hoppers. It will also be separate from the headframe. I couldn’t find pics of any other prototype that was set up this way, so I engineered something based on what I know of how wooden ore bins, water towers, and other such structures are designed. The upper part of the structure forms a sort of bridge and cradles the bin:

Then I added legs and bracing. Here are a couple shots of it temporarily in position on the layout. There are still a few braces to add, plus NBW details, etc. I also need to cast concrete foundations on either side of the track:

This last photo shows where I have chiseled away a clearing for the hoist house (upper left) and the beginnings of the mine shaft. The shaft pit will only be a few inches deep, with the bottom painted black. I need to pour a foundation for the hoist house, and create a collar for the shaft, before I can build the hoist house and head frame.

Meanwhile, I’ve also done some work on the mill at Mineral Ridge. I’ve built a wooden ore bin that will become part of the mill structure:

That’s all for now. Enjoy!

Ray, I cannot wait to see the final photos. I just got home from a trip through copper country in Arizona, traveling from Jerome to Bisbee. Thought of you many times in these towns.

You are an inspiration to all.

OK. Your are now officially a genius n my book. No way I would have ever been able to figure out how to make the discharge. You make it look easy…

#4

Ray, WOW great job. love yore layout.

#5

Amazing work Ray. Jon is right, you make it look so easy. The details are amazing…

#6

Ditto what they all said…:wink:

#7

Very nice, Ray. I am always amazed at what is available from Plastruct and you sure made good use of it.

#8

Very nice work Ray…you are truly an inspiration! Ingenious work on the discharge chute.

Ray,

Great modeling! True “hard rock” mining.

#11

Thanks guys!

I forgot to mention, one thing that helped was that the Plastruct cone has faint mold lines on it, dividing it into four sections. So when I cut the styrene sheets to fit the cone, I was able to trace these marks and use them to create the pattern to fit the styrene to the cone shape.

 That's all for now. Enjoy!

Ray what type of snake are those?

Snake?

I have a 4’ carpenter’s level extending from the mine tunnel to yet-to-be-built upper level of the mill, above the ore bin. This represents where the mine track will go, crossing a small bridge to reach the ore mill. The board on the ore bin represents another bridge for a mine tram coming from the area above the town, off to the left.

#14

Highly creative, as usual, Ray. A delight to see your work.

#15

So I’m readin’ all the posts, lookin’ for something from Dunakin and thinkin’, “It’s quiet, too dang quiet.” I mean, it’s December, which is prime modeling season and the guy’s writing about Christmas Light displays and such. Then bam, right after New Years, comes this. Does this guy ever sleep? Or stop building one unique thing after another?

Ray, you never cease to amaze me. Neato!

#16

Looks great Ray.

As a former Mining Engineer it is my opinion that you have designed a very plausible ore bin. I would suggest adding a chain and pulley system instead of just a lever. All that weight of the rocks on top of the gates would have made it very difficult to move them to open.

#17

Ray, Just another WOW build from the land of Sunshine.

Me thinks that somewhere within that build, there would be a place for one of the “Challenge” doors. You need to get in with the rest of the crazies and show us what you can do ;).

#18

Looks great, cant wait to see it completed.

#19

I agree with everyone “Nice Build” . I also agree with Dave T. You need to get a door and get in on the build challenge.

Happy RRing

Time for an update!

I had previously prepared the site by digging out the soil under the spur and pouring in a rough concrete base. Now I smoothed and leveled it by adding a layer of tinted mortar, squashed down with a piece of foam core art board. Two strips of foam core were glued to the top to stiffen it.

When this had set, I hot-glued some simple forms for the ore bin foundation, and filled them with mortar:

Meanwhile, I used exterior, latex house paint to paint the wooden frame of the ore bin. Although the wood is Western red cedar, I still wanted the protection of a good coat of paint for maximum durability. And so, ironically, I was attempting to paint wood to look like wood. For some reason I struggled with this more than usual, but eventually got it to look enough like old wooden timbers. It’s not great but it’ll do:

After it was painted I added some NBWs from Ozark Miniatures.

Next I painted the ore bin, again using latex house paints. I chose several shade of brown, primarily dark brown, chocolate brown and a rusty brown. At Home Depot you can buy custom mixed paints in “sample” size jars, which is convenient for modeling.

The paints were stipple on with a cheap 1" brush. After the initial coating had dried I added some streaks, by dribbling thin washes down the sides. Later I added more, subtler streaks using the dry brush technique. A little more stippling and streaking was done until I was satisfied with the look.

Sometimes old mines had the name of the mine, or the mining company, painted prominently on a building or other mine structure. This ore bin seemed like the perfect candidate for that. So I laid out the text in a drawing program, and printed it onto self-adhesive vinyl. Then I drew directly on the vinyl, modifying some of the letters to give it more of a freelanced, hand-painted look and less like a modern font.

I cut out the letters and used the vinyl as a stencil. I mixed “antique white” with some of my rusty metal colors, and stippled it with a stencil brush. After removing the stencil I did a little touch up, added streaks, etc as desired, by hand. Here is the result:

There are just a few minor things left to do with this ore bin. I have to add some stains to the foundations, and install a lever to open and close the ore gates, and possibly add some lights. I also need to ballast the track and blend the edges of the “soil”.

Next will be creating the mine, headframe and hoist house.
