Another mans way of making rugged scenery for the layout and as a bonus gets rid of some of that packing material you may have stashed away

The things you find out...
At the bottom of the topic of cliff building it says something about using a vacuum cleaner to collect the scatter that is being held down by the now dry glue.

I've been thinking about getting one of those mini vacuum cleaners that don't use waste storage bags to make it easy to re-use the scatter.

I wasn't thinking outside the square however and the simple solution is, as they then say, to place a cloth over the intake of the vacuum cleaner pipe to catch and reuse the scatter.
Doh...

I think they usually suggest some womens tights but when I tried that it worked for a few seconds before sucking the entire tights up along with all the scatter, so a small dedicated bagless one may be the way to go after all!

Well, I'll give the cloth/tights a go and let you know how I get on.

Remember to take the tights off  T  first, Marty otherwise....

(actually it maybe safer if you ask her for an old pair)

Tights work, but so does a yellow duster, so on reflection it may be less of a domestic issue to buy   .....   :cool::cool:

Plasterboard can make pretty good cliffs and rocky outcrops.  Here is one I knocked up yesterday.

Hi All. I am a bit late with my comments. But, aren’t Polystyrene Tiles a Health Hazard, apart from bursting into flames, I have read that some contain “Asbestos “ I don’t know if this is correct, but whatever colour , if it is present surely the of breaking off, of odd bits to create rock strata would create clouds of fine particulates that would float around in the air undetected around the house.  Best wishes Kevin

Polystyrene tiles have never contained asbsestos, they are made of... polystyrene.

Expanded Polystyrene  breaks up into a snowstorm of small bubbles, no fine particulates.

Asbestos has been banned for some years, there is nothing you can buy today that would release it into the atmosphere..



Modern polystyrene tiles do have a flame inhibitor in them.



If you've got your model railway hot enough for the polystyrene coated in plaster  to catch fire , then you have a lot more to worry about than the tiles...

Gotta ask why your posting on a ten year old thread, where the link for the subject no longer works.

Hi the Q.   In the last week looking towards the foreign subject of Scenery, I googled Cliffs and rock faces, and this Modeller was breaking up Polystyrene ceiling tiles. That looks like a good idea, I thought. Next I looked online for Polystyrene ceiling tiles, and that is where I read it . As unlikely that it seemed, I thought that I would check it out on YMRC.  Best wishes k

Hi Ed.  You may have read my comments on Scenery? To me Scenery of any type is a foreign subject. As I have never got close to doing any kind of scenery before. And with my scenic break being naked in readiness for the addition of Tunnel Portals and even a cutting, I turned to YMRC to get some answers. But I have ended up with questions on a foreign subject, ie Scenery, any advice is always welcome. Best wishes Kevin

Why don't you start a thread Kevin with a picture (since you've mastered posting pictures) of the area and ask for suggestions to make what you want. e.g. hills or embankments etc.

There is a Peco Shows You How series booklet on 'Modelling the Landscape', don't know if it's any good, but may help.

£1 from model shops or maybe W H Smiths (I know you don't like buying online).

Hi Ed.  Thank you for your reply. I have already begun a thread “ Kevin s Inglenook junction “ precisely for that very reason. Which shows the “ Bare Scenic Break “ to which I am referring. And I have had some replies . Best wishes Kevin

Got to disagree Matt, the highlighted link to 'Polystyrene Cliffs' comes up with Domain Name For Sale, so you can't really tell what Marty and the other members are referring to :???:

Hi Marty.  You have started something with tights, I am trying to figure out the scatter problem and weeds growing out of a Rockface, now that I have got rid of the gremlins from my electrics , I can get on with other stuff as all scenery is new to me.   Best wishes Kevin

True Ed but not a complete waste of time as it made me take five minutes to look at the link. The original site is gone but there was an article here on YMRC that contained most of the information, unfortunately no pictures as they are gone from photobucket, but still a good read ! 
   I've amended the original link to re direct to This old article

I don't hold out much hope of replacing the photos but I'll add it to the list  :roll:


Cheers

Matt

White packing styrene sheets are usually not suitable for rocks, embankments or similar. Same goes for ceiling tiles. Usually too soft, and the cells are too big for sanding or cutting with a saw. HD closed cell foam sheets 0.5 to 2 inches thick as used for insulation in walls is much better. And is best cut and sculpted with a hot knife or hot wire. It also sands nicely with 320 grit paper. Make rock cracks or crevices with a pointy object or the hot knife (old dart heads are ideal). You can even carve bricks, stones or blocks using a dart head.

While it is tempting to use tenon saws, the bread knife or the Sunday roast carving knife, don't. They will be blunt beyond redemption after 5 minutes. Use disposable blades (Stanley or similar), even they will be blunt after a few cuts. Hot knives, or hot wires cut and sculpt it easily, and with a bit of practice the foam will look the job. Watch the dust generated while sanding, I run the shop vac while doing it, otherwise the whole house will be covered in tasteful pink or blue dust. Accompanied with the cry of "what have you been doing!".

Make sure the correct adhesive is used. There are special CA glues for styrene foam, as well as caulk type construction adhesive. Closed cell styrene foam will generally take solvent-based spray paint if the original finished surface is there, if not it will be eaten away. Plaster cloth stick well to a sanded surface.

Or you can just get some rock molds and make your own using plaster of Paris. Much heavier though.

Hi Nigel     Thank you for your reply. After being advised on the dodgy content of YouTube videos, I watched one, bearing in mind that advice, of a Modeller “attacking” the foam with a flame from a small blow torch ( chef type)not for me though, for all I know he could have had the fire brigade.l department standing by. By my standards ( none)
a couple of sheets of O gauge stonework wall reinforced with something suitable would fit the bill, suitably shaped and weathered. If my plank or modules were to remain “ portable “ ? light is the key word. Best wishes Kevin

Hi Kevin,

Yes I saw that one. Heating sytrene foam with a naked flame can get quite dangerous. Ijit comes to mind. Hence hot blades and wires. For your purposes some reinforced card with printed weathered bricks or stones glued to it is all that is required. I was actually thinking Lego bricks would do the job. Glue or screw the bases to the board either side of the tracks, make 4 sections of bricks glued together and weather them, drop in place as required, but O scale? Going up in the world?

Hi Nigel.  Thank you again . There is a Members layout on YMRC in OO Gauge and he uses O gauge brick walls on his layout to good effect.   Best wishes Kevin

I find expanded polystyrene quite satisfactory for rocks once you've covered them in plaster.

As for Knives for cutting poly, visit a pound shop, packs of half a dozen very sharp break off knives for ....

Hi the Q.  Thank you for your reply. I will “ Bank that info “ as I must sort out my Electrics first. And it should be straightforward? Which it is?   Best wishes Kevin
