Making a jigsaw


Having retreated 5 mm from the end of the aluminum square, you need to drill through it. The drill is selected with a diameter so that it can accommodate the saw blade for a shaped cut. Then you need to lighten the side so that you get into the previous hole, but without going through the square.

After this, you need to make a mark on the square, clamp it in a vice, and bend the L-shaped workpiece along it at a right angle.The cutting depth of the finished tool will depend on the length of the indentation from the edge when bending. After this, you need to straighten the bend with a file, removing the protruding deformed metal.

The length of the L-shaped workpiece after bending should be selected depending on which files will be used: 130 mm, 160 mm or more. The design allows for adjustment to suit different fabrics, so the length of the larger side can be left at least 20 cm.

To connect 2 workpieces together into a jigsaw frame, you need to make a jumper for them. It will consist of 2 strips of aluminum sheet. Their length should be 10 mm longer than the short side of the L-shaped part. The jumper will be screwed to the square with the handle. On the other side, 2 square inserts will be attached to it with screws, between which an L-shaped blank will be located. This will allow the latter to slide.
