Hi Dorian. Contact Woodworks who sells some very nice wooden sheets of corrugated steel roofing.

Really very simple, just bleedin' time consuming.

Depending on your era, corrugated sheet tin would be 27.5 inches wide (and approximately 72 inches in length). In NZ120 1 foot = 2.5mm, 27.5 inches = 2.3 scale feet or 5.75mm. There are 4 ridges per foot, so a ridge every 0.5 mm. is near enough. I cut a sheet of thin but strong art card to just slightly larger than the scale size of one corrugated panel, mark off every 0.5mm top and bottom, and connect the dots with a fine scribe. Take thin fuse wire, cut to length and straighten each strand with a pair of tweasers. Paint the card with a very thin coat of white glue and allow this to almost set (you want it tacky). Lay the fuse wire into the scribed lines (every 0.5mm.) making sure they do not touch one another. Allow to dry, and your jig is now finished.

For tin I have found that aluminum foil can (sometimes) be too thin to work with. Aluminum pie plates/baking trays you purchase in the supermarket cooking supplies dept. are a better source but may not take the jig impression all that well. When I find a good source of (inexpensive) foil I'll post it. Cut individual sheets to scale size, lay it over the jig and burnish with a sanding block (if using the pie plate/baking tray foil you will need to apply some pressure for it to ridge properly). Voila! One sheet of corrugated tin. 99 more to go ...  

Corrugated tin is meant to be laid alternately lap up, lap down, which gives a one and a half corrugation overlap, but with the laps facing in opposite directions.

Nails can be simulated by dimpling the underside of your corrugated sheet with a sharp pencil point (If you intend to go this far, it is best to lightly pencil in the line you wish to follow on the underside of the sheet before jigging it.) In common practice there is a nail every second or third peak at the lower edge of the roof and where the ends of sheets overlap. Other nails, including at the edge of the ridging, are at every fourth peak.

The fun of this method (individual sheets) is that you can peel an edge back every so often for a distressed wall or roof effect.

Thanks, ECMT. Had had a look in their online catalogue but únfortunately didnt see anything mentioned there.

Umm unsure on my facts here or on authentication but i think there is a paint shop in christchurch that sells clear paper backing with what looks lined silver on other side but feels rough  will get back to this tomoro  but yea   u seem to have ur info from above

 hi if you used a round cylinder to rap the fuse wire around then you could roll it along the aluminium?  hence long run.

FWIW

There may be a somewhat simpler way, although it requires a bit of effort - wallpaper!!

For many years I have used suitably-sized sections cut off a roll of suitably-embossed 1970's-era wallpaper which I bought from an Op' shop for 0.50 cents!  This was an idea suggested by Merv' Smith, in 'Little Trains', and works well - at least for me.  The wallpaper I use (No idea what the catalogue name for the pattern was), has raised parallel lines on both sides, the advantage of being flexible and easy to cut, and takes acrylics well. From 2-feet away, others say that it looks realistic.

Finding a suitably-ridged roll does however require a bit of effort and will result in you having to go into all and any Op' shop you come across - just in case!  Eventually however . . .

As I said, FWIW - hope it helps. 

Happy searching.

Howdy Komata,

Ah! The old "ribbed wallpaper as corrugated iron roofing" trick, eh? Yes, it is indeed one possibility.

I'm currently investigating the possiblity of very, very fine corrugated art card; I'm just waiting for someone to get back to me with specific details on said product and where it can be obtained from.

On the Wikipedia page re: Corrugate Galvanised Iron, there is a photo of an early cylinderical rolling press such as you describe (its "like a mangle with humps", as SWMBO described it.)

Dorian

How about a plastic hair comb with teeth of the correct pitch drawn across the heavy tinfoil laid on a soft surface?? I tried this with several layers of standard baking tinfoil folded back on itself, but the effect was not that convincing... I think it needs the thicker pie plate foil.

The teeth of a set of electric hair-clippers are about the right pitch also. However, I suspect these would not give the same "curved" corrugations as the plastic hair comb teeth would.

Re the art card - "Spotlight" may be a source.

Hi all

I have some wood siding in corrugated profile; the smallest size is fairly coarse for NZ120, 1mm pitch, which is 57% over-scale.  I think it is supposed to be HO-scale roofing.  Also available is scribed and bevelback weatherboard profiles suitable for NZ120, all are $7.70 for a 610x89mm sheet.  Any interested persons drop me an e-mail.  I am drawing up some buildings to be laser-cut as complete kits from this stuff; yard-master's office, station and goods shed for starters.  Don't ask 'how much' ;-) , I haven't worked it out yet.

My website sorely needs updating, but my ISP was recently bought out by another, and now no-one knows who is responsible for maintaining it, which is presenting a few challenges with regards to updating it.

Possibly worth consideration is some N scale corrugated iron listed on Trade me at present of Right Track brand (#313133307) - its a 1 metre roll ($10.90 buy now) - scaled at (1:160??) as 2.64m (8.7') sheet, 22mm wide, corrugations at 0.66 -0.80 (3") per the Tme notes ???. Supplier is located somewhere in Kapiti. have ordered one roll to try.

Attached are a couple of pix of that Right Track N scale corrugated iron ex Trademe - lined up against a TTn3.5 scale paper ruler in one pix - Seems similar to the material that Campbell Scale Models used to use in their HO scale kits - will need a bit of gentle "flattening" to smooth out the wrinkles due to way it is packaged - not sure how it takes glue, paint, weathering etc - will test some out and post results. Worth a try though.

I've also got some N Right Track roofing material coming from the same source as Weeduggie's, but another way of producing CI can be found on this site, about halfway down the page: www.igg.org.uk/gansg/12-linind/models.htm
