1⁄35Realistic Corrugated Iron
Corrugated Iron SheetsIncreasingly I am finding more fun in finding ways to scratch build things than building the models that go with them. Having said that I am pretty intolerant of a result that does not look 100% realistic, and work to the motto “More real than real”. I needed some corrugated iron sheets for building a shed, and was surprised to find little or no styrene sheet available for this. After a chat with Vinnie I discovered that Plastruct in US make a 1:32 scale sheet that is close enough in scale but too thick to be accurate. Having begged a section from Vinnie (thanks Vinnie), I went to work on making some.
You will needAluminium kitchen foil PVA glue mixed 50/50 with water in a cheap spray atomiser A Hama ruler with a built in cutter ($10 - widely available – I got mine here, check worldwide distributors here ) Some Plastruct 1:32 corrugated styrene sheet ( here ) A soft cloth, and a very smooth (glass preferably) surface Note: The Hama cutter is a must – I have found no other way of cutting the foil accurately without tearing.
Getting started1. Cut about 30-40cm of foil from the roll (try and get a 900 cut) 2. Place on the smooth surface and rub with the soft cloth until smooth. 3. Carefully fold in half, create the sharp fold, and reopen 4. Spray some glue onto one of the inner halves, and spread thinly with some tissue until the whole surface is coated. 5. Working from the crease outwards, fold the two halves back together and smooth down again when finished. 6. Take the glued piece and repeat steps 3-5. Between each step repeat step 2 You will now have a solid sheet of smooth double folded foil. Working from the creased side, measure and trim excess to create a perfect rectangle. Now mearsure and cut as many 6x3cm sections as you can get from the section.
FormingTake a single piece and place it lengthways on the styrene sheet so that the long edges are roughly along two of the raised sections of the profile (female section). Now take a (previously cut) thinner section of the sheet (male section), place it on top of the foil and press firmly downwards. Flip the foil over and repeat. Remove the created section. If it does not come out right, smooth it down and do it again.
PaintingI primed mine with red and grey automotive primer (the red being visible in the dio). When spraying, do not fix them to the surface as removing them afterwards will seriously distort them – instead drop one at a time loose on a surface and give it a quick burst from a vertical angle. This is done for two reasons: 1. At any other angle it blow away 2. Spraying more than one will cause a wet one to blow onto another wet one and stick together (voice of experience) Once dry, run them through the forming process again to eliminate any bends/flats that were incurred during the spraying. They can then be applied to any structure you want, or used as debris.
The Good bit.Once painted the sections can be re-formed as many times as you want without damage or cracking/peeling of paint. You can also cut the sections to fit an angled roof, and reform it before sticking it down. You can apply totally realistic dents/creases/folds, and reform if not happy.
