First attempts at rock casting

I've been hesitant about casting rocks and starting mountain detailing, but a couple of days ago I decided to just jump right into it.

Over the summer I made about a dozen latex rock molds - a few are shown here. The idea was to give me some variety and spares in case I ruined some, which it turns out I did.

Up there is my first attempt. I used CelluClay as the casting material. 


After around 6 hours I peeled off the mold and that is what I was left with. The casting is a bit furry and rough as I haven't cleaned it up, but it seems rocky. I should note I used a mixture of castor oil and IPA as a mold release. I think when I tried casting rocks back in the 70s I used vaseline as a mold release; however, I read somewhere recently that a mold release shouldn't be based on petroleum products as it will attack latex. I don't recall what happened to those 70s molds, but I figured better safe than sorry as I won't be able to make any more molds until next spring.

I should also note that after 6 hours the casting was still soft. I figured that was due to limited air exposure while the mold was still on. After peeling off the mold, and allowing the casting to dry with its outer surface exposed to the air, the casting was hardened by the next morning.


I also tried making a casting with Great Stuff spray foam. I squirted some in a mold, made sure the mold was evenly coated, and applied it to the mountain side.


This wasn't successful. The upshot was I was left with a gloppy mess and a ruined mold. I think this was due to little air exposure for the foam and a not thick enough coating of mold release. I may revisit this by spraying foam in a mold, letting it hardened, and then gluing the foam rock to the mountain. It's a good thing I made a few extra molds. 

Anyway, foamy blues aside, it's happy days here making rocks at all hours of the day and night.

A Belgian-French E. L. Moore Machine Shop

On the left is the classic E. L. Moore designed Machine Shop kit reboxing by Pola.

It never ceases to amaze me where E. L. Moore influences show up. I stumbled across that photograph in issue #729, April 2008, of the French model railroading magazine Loco Revue in an article about modelling brickwork called Une brique dans le ventre (JDL: My rough translation: A brick in the stomach (! ?)) by Jacques Le Plat.

The caption translates to something like:

"The representation of plaster can transform the appearance of a common model, such as this Pola 814 workshop, full of charm despite its approximate masonry (transformation described in Good Kisses by Ferbach). The company name temporarily illustrated here was taken from the Yellow Pages directory."

Pola 814 is the Pola reboxing of the Machine Shop kit (a picture of which can be found here). I have no idea what "Good Kisses by Ferbach" refers to although I'll try and figure it out, and maybe revisit my 'translation' :-)

It seems E. L. Moore influences live on throughout the world.

Mocking up a stand for the Mt. Lowe layout

I've had an idea for a stand for the Mt. Lowe layout for a longtime and decided I should go ahead and mock it up before I got too deep into detailed scenery work.

Basically, it's just 3, 8" diameter by 15-1/2" tall cardboard concrete form tubes placed together in a closest packing arrangement.


They haven't been joined together yet as I'm still playing with ideas, but yes, once I've settled on a design they'll be attached together for stability. 

I chose the tube height for this test article based on the height of our family room coffee table. It's 16" tall with 15-1/2" tall legs and a 1/2" thick top. This size meant 3 leg tubes could easily be cut from a 4' long piece of concrete forming tube sold at a local home renovation store. 

I've wrapped a piece of woodgrain contact paper on the front tube in the photo to see how it would look. I might see if I can buy some contact paper with a slightly darker grain as the roll I have seems a bit too light. In the end I'm after a look that might suggest the whole setup was purchased from the 1976 Radio Shack catalogue :-) 

Nomadic Furniture 1 from 1973 | Nomadic Furniture 2 from 1974

Ok, the stand might not have been inspired by a 70s Radio Shack catalogue, but it was derived from a picture in the 1973 book, Nomadic Furniture 1. In Nomadic Furniture 2 the authors note work finished on volume 1 in August 1972 and it shows. Both volumes are clearly products of early 70s thinking. I didn't have a copy of volume 1 until 1980 or so, although I'd heard of its existence. I stumbled across volume 2 at The World's Biggest Bookstore in a bargain bin in the late 80s.

Table tube stand on page 48 of Nomadic Furniture 1

The idea is based on a table that uses 5 cardboard tubes for legs shown in the above photo. Frankly, it looks a bit unstable to me, but I haven't built one so I can't say for certain. I can say though my 3 tube, trefoil-like coffee table layout version is quite stable. 

I need to fiddle a bit with tube-to-layout-base attachments to see how this thing stands up to being knocked. Galen at one time suggested some sort of Lazy-Susan type connection so the layout could easily be turned for accessing different views. I like that idea. I just need to work out the details.

When the cuttin' was done the only part that wasn't foamy ...

 ... were the soles of the small man's feet.

Well, they were a bit foamy too if the trail of foam bits going up the basement stairs and into the house are anything to go by.


After I vacuum the carpeting I'm going to switch gears and alternate between making and installing rock castings and shaping the foam structure. I was thinking this would be a better approach as the final shape will develop more iteratively, which I think will result in a more interesting mountain.

Let's start the weekend with a little vacuuming music:

Ain't No Mountain Lowe Enough

Result of wart trimming with knives and saws

I thought I'd try using a hot wire foam cutter to trim and shape all the Great Stuff warts. Things didn't work out.


I went to my local hobby shop and bought a brand new hot wire cutter (made by that scenery company whose initials are WS), but no matter what I did, no matter how I fiddled and adjusted and reassembled it, the wire would not heat up. It was stone cold. After a long while I gave up and pulled out the knives and saws and sanding blocks and went at trimming and shaping the mountain old school style. I'm only about 1/3 of the way through, but things aren't looking too bad even though it's taking much more work than I had planned on.

I don't want to end on a low(e) note, so I'll leave you with the legendary Tammi Terrell and Marvin Gaye*:


*As well as a great song sung by great performers there's an added train bonus in this video. The song was released in 1967 and it looks like the video was shot at Expo '67 somewhere near the Ontario pavilion. At the 2:43 mark you can clearly see the Minirail passing by as well as making a brief appearance earlier in the video.

Mountain o' Warts

Foam warts cover the mountain after spraying the gaps with Great Stuff

I took the layout outside to fill all the gaps in the mountain with Great Stuff spray foam. I wanted to use it to make the mountain as rigid as possible before applying rock castings, and to begin the process of creating rock-like surfaces.


The first step was the cover all the track with masking tape. It's extremely difficult to get solidified Great Stuff off track, especially switches which can be destroyed, so all the track has to be covered.


Believe it or not I was quite sparing as I squirted foam into the gaps and did a little filling. Even the low expansion type I used expanded quite a bit. I haven't used Great Stuff in a long time and I'm out of practice. 

In the next exciting instalment I discover my brand new, never used before, hot wire foam cutter refuses to work forcing the deployment of knives and saws to trim and shape the warty foam. All that and more next time on Adventures on Foam Mountain!

Coming Attractions: Artz Lumber Co.

I've been wanting to build Art Curren's project Artz Lumber Co. for a long time and decided this winter is the winter of Artz.

The project needs three Atlas #750 lumberyard kits and an AHM #15303 farmhouse kit for the office. I just want to build the lumber shed so I don't need a farmhouse kit. Artz is going to be a part of a diorama along with Cal's Lumberyard, which has an office on the side. The diorama will be a project for next year. If you're going to follow along, Curren's article appeared in Model Railroader's Dec '86 issue and was reprinted in his 1988 book Kitbashing HO Model Railroad Structures. I won't be copying out the steps in my posts, just muddling along as usual. I'm curious to see how a Curren build goes as I've never done one before even though I've written a few posts about his writings.

In March I was lucky to find an old Atlas kit from the 1960s at the local model railroad swap meet - it's the kit at the top of the triangle in the photo. I'm not sure when this particular instance was manufactured, but the kit was first released in 1962. I did a little looking in Model Railroader and Railroad Model Craftsman to see when ads for it first appeared. The earliest ad in MR appears in the Oct '62 issue, and is followed up by ones in Nov '62 (includes a small picture) and Jan '63 (includes a big picture). After that it appears with some regularity. I couldn't find any ads in RMC for either '62 or '63.

New kits are still being sold today. I acquired those two new ones in the bottom row of the photo just this week, although there was a lengthy search to find a pair at a reasonable price.

Well, I've got the kits. I'm just waiting for the snow to fly!

Mountain o' Foam

I spent some time roughing in all the mountain shapes with odds-and-ends of foam sheeting. I wanted to have all the basic shapes established and adequate support in place before I started casting rock surfaces from the molds.

All the supporting foam is in place except for the pieces that will make up the Granite Gate. I'm still thinking about how to make that shape.


Those little black boxes that have been inset in the styrofoam walls shown in the above photo house the on-off power switches for the nearby track switches. They were built up from scrap pieces of 0.080" thick styrene.


This 'back' part will look rather foreboding once it has been detailed. I'm playing with ideas to visually bridge the two lobes to lessen that feeling. 

The next step will be to squirt some spray foam into any gaps between the foam pieces so the structure is as rigid as I can get.

Tales of The Midnight Hobby Shop, Part 2

When we left Ed and Frank they were marvelling over the disappearing model kit that didn’t disappear. Get a beverage. It’s time for part 2:

I can’t overestimate the healing powers of coffee and a bagel, especially at Del’s. It was quarter after three and there was no one in the place except Frank and me. We asked Del to set ’em up as we had a little story to hash over we thought the client should know. We were drinking coffee to end a strange episode, so we made it a cup for the kit and one more for the midnight hobby shop.


“I think we should drive over to my place to have an early breakfast meeting with the client. I’ll call Leslie and see if she’s good with that. Can you call the client and convince him to come over right away?”


“Yeah, but do you think the kit is ok in my car?”


“I don’t know. I don’t want to open it until we get it to a safe place.”


“Where’s that?”


“I don’t know that either, but it’s not here in public.”


I put some bills on the table and we headed to the phone booth outside.



Leslie picked up the phone after the first ring.


“You’re up?”


“I couldn’t get back to sleep after you left.”


“Sorry about that.”


“It’s ok. What happened?”


“Same as usual, but this time one of the kits didn’t disappear.”


“You’re kidding!”


“No. I’ll tell you about it when I get home. I want to have a breakfast meeting with Frank and the client at our place in about half-an-hour. Would that be ok?”


“Sure, I’m up anyway and I want to hear everything.”


“We’re at Del’s. I’ll bring home some bagels and lox and coffee.”


“No coffee, I’ll make some.”


“We’ll be there in a few minutes. Love you.”


“Love you too.”


It was Frank’s turn. I gave him a dime and went back into Del’s to get some breakfast goodies. Frank was waiting by the phone booth when I came back outside.


“Is he coming over?”


“Yeah. He’s a bit grouchy about the time, but he’s coming.”


I gave Frank one of the bags of bagels and we went to our cars.



Our house isn’t much, but at least we’ve got a big kitchen table and lots of chairs. None of them match. Some came from the stash in my grandmother’s trolley shed, others from the remains of Leslie’s marriage, and others from who knows where. I always sit in the beat-up captain’s chair. My grandmother told me it was my granddad’s favourite. Now it’s mine.


We dealt some plates and utensils and I poured some of Leslie’s coffee into mugs. The three of us sat and ate and chatted and waited for the client.


“Frank, what’s the client’s name?”


“I don’t know. He pays with envelopes stuffed with cash squeezed into my mailbox, so I don’t ask too many questions.”


The front doorbell rang. Leslie got up from the table and padded through the hall to answer. Hopefully ‘The Client’ was behind door number one.


“Rob?”


“Hi Leslie.”


“Are you the client?”


“Yeap, that’s me.”


“Are you still with the lab?”


“No. Are you still there?”


“No. Not for a long time.”


Rob and Leslie stared at each other for an eternity of seconds. 


“Where are my manners? Please come in. They’re in the kitchen.”


Rob stepped over the threshold and started to take off his shoes.


“You can leave ‘em on. Come this way.”


Leslie lead. Rob followed.



After some howdy-dos, it-was-you-all-alongs, and friendly banter, accompanied by generous helpings of bagels and lox, we finally settled down. I figured it was now time to get it all on the table.


“Like I said, we’ve got a kit from a midnight hobby shop in the trunk of Frank’s car. What we don’t have is an explanation about what’s going on. So, what’s up?”


Rob began:


“It’s a bit of a long story. Earlier in the year I got these phone calls in the middle of the night telling me to go to such-and-such an address at such-and-such a time in the morning. Always different locations and different times. I figured it was some sort of scam or prank, so I would hang up and go back to sleep. I didn’t call the police because I didn’t think they’d do anything since the only crime was waking me up.”


“So, why’d you call us?”


“There was something else about the calls that bothered me that I didn’t want to tell the cops. The guy doing the talking sounded a lot like my son. I wasn’t sure. It was just a nagging feeling. The fourth time it happened I decided to get up and go. Look, we’ve been estranged for a few years. He’s got mental problems and a problem with booze. I thought maybe this was some strange way of his to get my attention. I’ve tried everything to find him, but I haven’t.”


I got up to refill everyone’s coffee. Rob continued:


“Ok, so I drove over to the place. I parked my car on a side street to try and keep a low profile. I walked over to the address. It’s some store all lit up in the middle of the night and it’s full of people. I go in. It’s some sort of hobby shop. I ask everyone about my son, but no one knows who I’m talking about and I get lots of odd looks. I don’t know what to make of it so I leave and figure it was some kind of sick joke after all. When I got to the street I turned around to give it one last look and all of a sudden all the lights instantly go out. Ok, I’m curious so I walk back to the store to see what’s going on. It’s a stationery store. All the hobby stuff is gone and it’s been replaced by pens and papers and the like.”


Frank and I gave each other a knowing glance. It sure sounded like what happened at Bruno’s Shoes. Rob continued:


“This is when I decided to call you guys. I’m a model maker like you and I know your company’s got a bit of a reputation in the community.”


Frank looked hurt and countered:


“Don’t believe everything you’ve heard.”


“Come on Frank. You and I learned model making from those aircraft recognition model classes they gave us in rehab during the war. I know you, and I know your company does all sorts of model related investigations. I figured if half the stories about your investigations were true, you were the guys to get to the bottom of this.”


“So why didn’t you come clean at the start? Why this man-of-mystery crap?”


“Look, I was embarrassed ok? I figured if I disguised my voice, told you just the barebones of what I wanted done, and paid you with a big pile of cash, you’d do your thing and not ask questions.”


Now it was Frank who was embarrassed. His old acquaintance knew him a bit too well.


“Ok fine, but what about …..”


Frank was cut off mid thought by a sheet-metally cacophony


thunk! bang! thunk! clang! thunkbang! thunk!


coming from the street.


We all jumped out of our chairs and bolted for the kitchen door. 


thunk! thunk! clang! bang! thunk!


The racket was coming from the trunk of Frank’s car. It was parked on the street, in front of our house. Frank and I ran to the curb.


The trunk was pockmarked with dents. Little hillocks had been hammered into its metal surface. From the inside.


I had to admit those Swedes knew how to build a car that could take a punch. This 27 year old senior citizen showed no sign of having its trunk seal broken; there were lots of dents, but it was still firmly closed.


Frank reached into his pocket for the key to open it.


“Don’t Frank, I….”


bang! 


This last bang raised a new little hillock and lit up a tsunami of house lights up and down the street. 


“Damn! Frank, get in the car and get out of here. My neighbours are calling the police as we speak. You need to get the hell out of here! I don’t want to explain this to the cops.”


“Go where?”


Panic was setting in.


“I don’t know, just get going! Call me when you’re there.”


Frank got in his car and drove off. Rob was standing on the lawn watching. I called to him:


“Get in your car and follow him! Don’t let him out of your sight!”


He skidded his car out of my driveway and raced after Frank.


As they turned right and away at the stop sign at the north end of the street I could hear a faint siren approaching from the south. 


As Leslie and I quickly walked back to the house I tried to concoct a story about musical raccoons using our trash cans as a drum set.
