Coping saws are used for cutting a range of woods and are very useful for cutting unusual shapes or curves. In a modern workshop these shapes are normally cut using machine fretsaws. However, there are times when these machines are not available. Also, using a coping saw is a test of skill as it can be difficult to control and requires practice.
|FITTING THE BLADE|
|The blade is 150mm in length and at each end there is a pin that holds the blade to the frame. To fit a new blade the frame has to be flexed (shown above) usually by applying a little pressure. The blade fits into two slotted pins on the frame of the coping saw and when pressure is released, the frame springs back to its original shape, holding the blade in position.|
|Care must be taken when fitting the blade so that the teeth point towards the handle. If the blade is fitted the opposite way the coping saw will be very difficult, if not impossible, to use.|
|A coping saw can be used to cut shapes in the middle of a piece of material. First, the blade is removed from the coping saw and then passed through a hole that has been drilled. The blade is then fitted to the coping saw frame. The saw can then be used in the normal way, cutting the ‘internal’ shape.|
