How to Cut Metal Roofing Using Three Tools?
To learn how to cut metal roofing, you must have a good understanding of the different tools used for this job. When learning how to cut metal roofing, you must be familiar with various metal cutting tools such as electric angle grinder, electric sander, and a band saw. This article will help you learn how to cut metal roofing by providing basic information about these tools.
As the first step, you must clean the surface that you will be cutting on. You will use an electric shears to remove the old coating of paint and gravel. You can then cut the rough edges with the use of electric angle grinder, and the edges will be sharper than before. However, if you’re cutting more than 1 inch off, it’s difficult to cut with tin snips because corrugated metal with thin edges is really hard to get to.
The second step is to prepare the surface to be worked on. Since the task is done at a higher altitude, the air pressure can be high during the procedure, so you should take the advantage of an oxygen supply or mask if available. Once you’re sure that the surface is ready, the next thing to do in learning how to cut metal roofing is to choose the best tool for the job. You need to find a tool that has a diamond studded disc or a diamond blade.
Another important thing when learning how to cut metal roofing is to pay close attention to the edges. You must make sure that all the edges are smooth and sharp so that you won’t cause yourself injury. This is especially true if you will use the tool on a corrugated metal roof. There are two basic types of edges to look out for: the smooth edge and the pointed edge. If you find a smooth edge, chances are, it’s made from aluminum or another light metal, which is not the best material to use when cutting metal.
When learning how to cut metal roofing, the last tool you will need is the angle grinder. This tool has a circular disc and a grinding wheel at its base. To grind something, you need to turn the wheel to the side so that the central shaft of the disc spins in a downward angle. If there are ridges on the disk, you will need to adjust the grinding angle until you get a smooth grinding effect. Another option is to use a hand grinder, but since you have no control over this angle, you will only get a coarse finish.
Metal workers need not despair; there is a third alternative to using tin snips and a straight cut wheel. This method does not require you to turn the grinding wheel, so you don’t have to worry about a counterweight. Instead, you will need an electric angle grinder. Unlike the tin snips, you can adjust the height of the angle grinder, which gives you better control while cutting.
