Thread: What tool to cut corrugated Iron

Here is an old carpenters trick for cutting corrugated iron lengthwise. Determine where the cut is to be made and make sure you turn the sheet over if required to get the cut in the bottom of a corrugation. Take a sharp cross-cut saw and hold it backwards (front of blade towards your body) and position the last tooth at the edge of the iron. Lift the front of the blade a couple of inches and hold it firmly (a bit of rag helps protect your hand), push firmly down on the top of the saw handle and drag the tooth down the full length of the corrugation. The tooth should make a deep scratch and it is important to keep it as one continuous gouge down the centre of the corrugation. Turn the sheet over and fold it back along the groove a couple of times and it will fracture neatly. Caution; the edges will be sharp! This is miles quicker and much safer than trying to use tin snips.
