The exact jigsawing technique you use will differ slightly depending upon the type of cut you are making.
However, the general cutting process will remain largely the same.
Before cutting
Because the teeth of a jigsaw blade point upwards, the cleanest cut will be on the underside of the material.
As a result, it is advisable to turn over your workpiece before marking and making your cut.
During cutting
To begin making a cut, place the front edge of the shoe of your jigsaw onto your workpiece and line up the blade with the cutting line.
As only a small portion of the shoe is in contact with the workpiece, it is important that you hold the jigsaw firmly with two hands so that it remains horizontal to the material.
When you are sure that your jigsaw is set solidly against the workpiece, turn on your jigsaw and allow the machine to gather speed.
Then, slowly, advance the saw along the cutting line. Do not force your tool, let it work at its own pace.
Proceed with your cut, increasing speed or altering the orbital action setting of your jigsaw if necessary.
Continue to firmly hold and steady the tool until you have reached the end of your cutting line.
