Oh so noice. My friend Greg, and YES, I do have friends, has gotten an even smaller printer nozzle for his 3D printing gadget and has now made me a roller set to make Corrugated Iron Sheets in N Scale !
So I have just now had a play with it - oh so kewl. He'd played with it using normal kitchen foil, as have I just now.
It does make a nice sheet of corrugated using normal kitchen foil. Buuuut, handling said sheets of iron is... delicate work as they are soooo damned tiny and thin and bendy. So out with the stuff I played with for the HO scale sheets - the foil used to seal your new cans of milo, ovaltine, gravy and all those sorts of food stuffs in the kitchen.
Now, here are some facts. I got the micrometer out and did some looking and calculating and here are the results - take with a grain of salt, as they a rough calc's - not meant to design a space rocket or such.
My Gravy Can Foil thickness measurements are:
2½ thou 0.0025"
0.07 mm
Milo/Ovaltine Can Foil:
2½ - 3 thou
0.07 - 0.9 mm 0.08 mm is the good average
Multix Alfoil - the normal kitchen type foil for cooking your din dins in:
0.75 thou
0.016 mm thickness
Now, the size of a real size sheet of corro does vary all over the place. But based on findings on the 'ol iternut webby thingamejig, they are about 2' or 2'6" wide. Buuuuut they do range... a LOT in length. 8 footsies looks a standard size from last century.
So if it is 2 ft 6 in x 8 ft sheets, then in modelling scales that equates to:
HO Scale: 8.75 mm x 28 mm
N Scale: 4.76 mm x 15.2 mm
And if they are 2 ft x 8 ft sheets:
HO Scale: 7 mm x 28 mm
N Scale: 3.8 mm x 15.2 mm
Remember, if you are cutting the foil BEFORE forming it, it will need to be a smidge wider to cater for all those ups and downs you are about to make in the sheet.
The kitchen foil is on the left and the can seal foil on the right.
Now after playing with the foils, I reckon they all work fine, but the thicker ones are sooooo much easier to work with. You can cut them with a #11 blade nicely whereas the kitchen foil really only cuts with scissors.
So now I have a roller set for both scales and can happily make roofing :-)
