I know many of you have seen this done before but I think there are as many who haven’t seen this technique. How to cut a curved line. Simple all you need is some string or heavy thread. Essentially the thread takes the place of a coping saw blade. I start by drawing the line I need to follow on the model. Then a tape the mode to the bench so it overhangs the edge to allow you to hold the length of thread above and below the object being cut.
By running the thread up and down you cut the plastic. Be careful not to use too much pressure or too much speed, this creates heat and will cause the plastic to melt and thread to snap. I cut through both halves of this helicopter in just a couple of minutes. It’s easy and it is fun. I was able to keep the tail boom and engines intact so it can be reused. Give it a try yourself.
