corrugated roof

[ndbprr]

Back when MR had a kinks section I recall reading you can make corrugated by using a file and pulling something like balsa or cardboard across the foil while in contact with the file.

Thanks all,

Hey Bob, the roof is glued to some wood that sits on top of the building, The problem is the bit that overhangs and is not supported by the wood. I watched the video on freerails and he seems to just use his finger to straighten the aluminium as he goes, so mabe I just need to persevere.

I was planning on scratching the join marks rather than individual 8 X 4 sheets as the overlap is a bit too thick I feel.

Thanks for everyone's help.

 Found a pretty good example of how to. Plus there's a video.Check it out.

Alan,

I have been recently putting roofing material on buildings. I have used a couple of products: Paper Creek Corrugated roof paper and Campbell’s aluminum corrugated material. The paper Creek stuff was easy and it looks good from a distance of 1 foot or farther way (see my post on page five of this weeks photo fun in the general discussion forum for a look at this material). The Campbell’s is quite a bit fussier to work with. Keeping it flat on the overlap is pretty difficult to do well.

I have a few suggestions from my experience with corrugated roofing material:

1. Make sure that you have a flat sub-roof or lid on the building that you can glue or some how attach the corrugated metal so it will lie flat. Styrene or hobby plywood works great for this.

2. “Prototype” Corrugated is often sold in sheets say 4’x 8’ etc. It is rare to see a roof done as one big piece. Try cutting your material into scale 4’ X 8’ or maybe 4’ X 6’ and then re-do the roof. Some modelers use sharp exacto knives, I get decent results from scissors. I usually try to figure out how many rows will fit without leaving a very short row, you may have to adjust your lengths to get things to look right. (i.e. three 6’ rows rather than two 8’rows with a 2’ remainder row).

3. Cut out a bunch of pieces and Start at the front bottom edge (leave a slight overhang) and go one direction across the roof, slightly over lapping the pieces. When you get to the end of the row go back and start form the same side again and lay down another row just overlapping the lower row. Use a straight edge to keep stuff straight.

4. The top ridge of the roof is typically 2’ X 6’ pieces folded long ways to make a roof cap, over lapped across the roof ridge line.

5. I recommend using super sticky double sided tape to hold the Campbells down. It works better for me than glue.

6. For finish you can spray the roof with grey etc when you are done or you can dullcoat it and use rust powders – both work well.

Good luck with the project. I have one friend who is an excellent modeler who confided in me recently that he uses the paper corrugated for everything that needs metal siding because he got tired of messing with the Aluminum stuff. I’m beginning to see his point.

My two cents,

Guy

Go to "Texture Sheets", then scroll down to Items 205 / 207.

Just another option.

Some corregated cardboard (like toy boxes) has very fine corregations in it, much more closely spaced than a regular cardboard box.  If you soaked off one side, leaving just the corregated piece, that might work.  Never done it, personally, so I can't really speak for the results.

Thanks Bogp40,

that would work if I'd damaged the corregations, but I've bent the roof, as you can see

 

 

I've still got some weathering to do on the roof too.

cheers 

Unless you want the building to be pristine, you could flaten the roofing and add repair/ patches. Once weathered it may look OK.

It is a shame, a very nice building.

 Thanks for the ideas, I like the aluminium idea. Going to go give it a try tonight. Thanks again. By the way I'm modeling in HO scale. Forgot to mention that.

I bought some already corregated sheets of aluminium, my problem is that after I glued them onto a roof, I bent some of the sheet that sticks out over the edge of the building.  I've tried to even out the bends but I only make it worse. Any ideas on how to make it look right?

TIA 

You could try the reverse of the threaded bolt just mentioned earlier. Lay the appropriate sized threaded bolt on the roofs' edge and tool the foil back into shape.

Hello nrq 484,

 I just take aluminum foil lid from a margarine cup or even the tin foil lid on the cat's food tin foil can make good candidates..

Flattening the foil first, lay in on a flat piece of balsa and drag any kind of all thread over the foil, leaving the corrugated imprints on the foil. The coarseness of the all thread will determine your corrugation..applicable to the scale you model in.

Rests you to cut the sheets to the scale of your liking, I model N scale..some white glue will stick the paltes to almost any surface..Weatthering with the usual paints..

 Give it a try , I'd say

After a few passes, the balsa tends to take the groove as well, otherwise you could drag the allthread over the balsa first to speed up the relief forming.

The nice part about the foil is that it contains a matte side, this

Buy a sheet of Evergreen corrugated roofing.

Tape a piece of paper/foil/.005 plastic toone of the long sides.  Starting from the taped side run a scribe or ball point pen down each groove.

Cut into pieces 4x8, 2x10, what ever size you want.  Make as much as you want.

Hello

You do not mention your scale, but if it is HO or larger you could of course make it yourself from aluminium foil (take a look in your kitchen drawers...) or buy Grant Line Walthers Part # 300-5218 - finished roofing materials. Or do as me, use Campell Corrugated Aluminium Sheets, also from  Walthers Part # 200-801. 

I use some time cutting the sheets into scale dimensions sheets (using a very sharp knife), and apply bit by bit on roof and/or walls. Start with the row at the bottom of the wall or roof, overlapping the previous sheet, both sideways and on the top. After mounting the foil, I let the model dry complete, then weather it. Depending on the model you may need to let it dry with the foil under light weights.

Good luck!

 Anyone have any ideas on how to make corrugated roofing. Any help would be greatly appreciated.
