I checked out US Plastics web site, very reasonable shipping but the sheet size was 40x72. I felt that 20" would end up being a bit too small. Perhaps I miss read that.

I have been seeking a plastics dealer in my area (seacoast NH) but not much success. For now I am using 1/8" tempered masonite. Not my favorite to work with but acceptable as I can get it at home depot.

I work in HO and based my backdrop on the article on p. 44 of the 03/2006 MR: .060 styrene strips stapled to the wood frame, then .080 styrene sheet secured to the strips with Weld-On #16 solvent cement (2-3 minute working time; plan carefully!). The cement is very strong, and I'm confident the backdrop will stay up and flat.

I did mine in (3) sections: The back (2'x6'), the side (2'x3'), and the coved corner to connect the two. I filled the seams with gap-filling CA, which I built up slowly and sanded smooth. I then followed the Dream, Plan, Build Volume 1 (I believe) tutorial on wet-on-wet painting for sky and clouds using flat latex housepaint. I practiced extensively on masonite before taking the plunge on the styrene for real. I'm no artist, but I'm pleased with the way it turned out.

I bought the .080 locally, a 4x8 sheet, for about $40 and the .060 through usplastics.com on the 'Net. USP has great customer service and decent prices. I had the sheet supplier rip the sheet into (2) 2x8 pieces--so my backdrop is 24" high. I would prefer a bit higher, but 24" is fine and saves the hassle and waste that, say, 30" would create.

I used modelers' tutorials on backdropwarehouse.com as a guide to make my 1x3 frame and the support pieces for the coved corner. I'm not particularly handy, but I think the completed backdrop looks good.

I am planing a backdrop. My considerations are. Camera view. When looking through my camera how high up the backdrop do I see. Next is field of view. This means when looking at my layout is my view broken because my backdrop is to low or not wide enough. My camera tells all.

One thing to keep in mind is that the higher the backdrop extends up, the easier it is to photograph the layout - you can do 'eye level' shots of trains without having to worry that the top of the backdrop will show. My last layout was a single level layout and I basically ran backdrop from the benchwork to the ceiling, about 36-40".

I stopped at Home Depot and picked up 3 masonite 2'x4' "handy-panels" for the backdrop.  Tommorow I'll start painting them and the backdrop should be done by the weekend.  Thanks for the help!

It's like .015mil thickness, but it holds up pretty well.  I used a 1x2 framework behind it and ran it pretty high up.  I used industrial staples to secure it.  My longest straight run is about 13', but the longer you go straight the closer to the top you need the support so it doesn't curl over with age.

I am building a spare bedroom sized N scale layout.  I bought several 4 x 8 sheets of .060 white styrene from a plastics dealer and had the dealer cut each sheet into two 2 x 8 strips for a small extra charge.  I needed very small radius coves since I could't waste much space so for each corner so I used a tight 5 1/2" radius.  I cut three concave plywood templates for each corner and mounted them in the corner (top, middle, bottom) of my desired backdrop.  This took a little time but when I put my backdrop sheets in place I had no trouble coming up with smooth uniform tight radius curves.  I placed the backdrop so that 18" was above the layout and 6" was below.  I had to make a couple of splices in the backdrop but they were not much trouble.  I used the same .060 styrene to make splice plates about 8" wide to go on the back of the backdrop glued with Gorilla Glue and left to dry overnight.  All splices and nail heads were countersunk slightly and filled with Squadron Plastic filler then sanded flush.  This was my first attempt and it came out better than I could have expected. 

The styrene is a little more expensive than other materials but I didn't want to worry about expansion cracks or other problems later when I couldn't reach the backdrop to repair it very well.  The photo also shows a removable panel across a window.  This seam shows slightly since it is not glued and filled but if I ever had to have access to the window I need to be able to easily remove the backdrop panel in front of it.

 I will try and post a photo but this is my first attempt at a photo so hope it works.

I used sheet styrene purchased from a plastics store in town.  I framed the corners (24" radius) and the styrene is glued to untaped drywall on stud walls.  The styrene was perfect for painting a sky back drop.

I use light blue craft paper, tacked to the walls:

Eventually, I plan on added some distant hills.

The trackplan of the layout purposely places the structures on the layout to hide the backdrop.  So the backdrop will just be mottled blue-ish grey with a few photos of buildings glued on to hide small gaps where you can see between structures.

Thanks,

I used 1/8" masonite 20" tall.

Something to consider is what are you going to put on it? If your going to hand paint it, you can make it whatever height you want. If you going to buy printed backdrops, you need to make it the same height as the commercial backdrop. Many of which are only 13" tall.
There's lots of great threads here on how to hand paint mountains, trees and clouds.

Thank you reklein,

I should have pointed out that it does kind of erase the effect if you go tighter, but it's still better then a hard lined corner.

On my layout the tight corners will either be hidden mostly by hills and such (I'm modeling Maine) or they are wrapping around the ends of the benchwork to where I'll have decorative woodwork.

How tight is too tight?  I was hoping to go down to 4" radius since the layout is so small anyway.  There won't be much on the backdrop besides sky so would that make a difference in how tight the coving could go.

For the material I will probably go with masonite and use strips of vinyl flooring so I could get tight corners, hiding the seams with joint compound.

Thanks,

Chad

 Mine's 24 ins high, and it never seems too high to me. I'd have it higher if I could, but it's free-standing and is wobbly enough already. [4mm scale layout] I'll be going with the same on the HO scale side of the table.

Hi,

I used 1/8 inch masonite for the corners of my 11x15 layout that fills a room.  The masonite was screwed into wall studs, with a four foot length making a 90 degree bend.  I used a 24 inch height, and I think I would go with 30 or 36 inches if I did it over.  My reason is that "landscape" pictures are hard to take without showing the walls above the 24inch masonite.

FWIW,

Mobilman44

ENJOY  !

Chad,

I used 1/8 untempered masonite and curved the corners.  As mentioned, you will need a pretty good frame to hold the corner curve made with masonite.  I used 1 x 2's and 1 x 3's, and glued and nailed the masonite on with brads.  They dissapear with spackle and paint.  

You may want to use something a little more flexable in the corners.

I had poor luck attaching preprinted backdrops from Walthers. They were installed using rubber cement, and became a little wrinkled after a few days.  I used a steam iron to salvage it to some extent, but now I see it is falling loose at some seams.  The sky colors are a very poor match from one scene to the next.   If I do it again I will paint my own backdrop. 

I used and like the 24 inch height on my HO layout.

Phillip has a good idea about the vinyl. Another product that will work well for the tight curves is styrene or Aluminum coil stock. Whatever product is more readily available to you should be fine.

I would contact cement or Pliobond the material to some sort of substrate, especially the aluminum. Any 1/4" sheet stock, masonite, MDF or my choice Luan should be sufficient.

Masonite is a popular material to use, though I don't know how tight you could cove it, even if you wet it a little.  You could also use the back side of a strip of vinyl flooring, but that will need a pretty good support framework.  I chose vinyl flashing.  It bends nicely and requires a minimum of support framework.  I got a couple of three rolls for like $25 a roll at the local Home Depot and it's more then enough to my whole double decked N scale 10x15 layout with some left over.

I went with 20" tall (it comes that high, so it was easy!), though being in N scale I could've gone less.  The hieght you go will depend somewhat on the scale.  18" for N scale is good and maybe getting down to a minimum for HO, but then thats just me.

Here's my vinyl flashing going up on my layout.  It's not painted and still has unsanded putty on the stapes that I used to hang it, so pardon the mess.

Here you can see the front of the backdrop on the lower level and the backside with the 1x2 framework on the upper level.

Here you can see how tight of a curve you can do with it.

Backdrop Questions
Posted by chadw on Sunday, February 10, 2008 1:12 PM

I want to add a backdrop to my 2x8 layout.  The backdrop would go along the back and both 2' sides with tight coved corners.  I have a couple questions though.  One is what is a good material, and the other is how high should the backdrop continue above the layout.  The layout is already at 5'2" (just slightly below eye level for me).  I was going to make it 18" but even that seems high.

Thanks,

Chad
