Jigsaws are the perfect options for making curved cuts, but they can also handle straight line cuts. The process is not complicated. Use a G-Clamp to hold the workpiece properly and guide the foot of the jigsaw carefully. While manipulating the jigsaw, try your best to make sure the appropriate speed is maintained. The appropriate cutting speed is typically not fast to maintain order. Also, you will be doing yourself a favor by drawing out the intended line before cutting. A measuring tape and a square are enough as a guide through the whole process.
