It is quite possible to make a jigsaw with your own hands. As a basis, you can take both wooden and metal blanks. In the first case, it is easier to act, but in the second case, the tool will turn out to be more reliable and durable. Step-by-step instructions with a photo and a description of the action are presented in this article.

Portable wood jigsaw
Do-it-yourself electric jigsaw can be made from wooden parts. This option is easy to manufacture and durable. For work you will need such materials and tools:
- plywood from several layers;
- jigsaw files (must have pins);
- glue for wood;
- 12 V battery;
- spring;
- switch;
- annealed wire;
- a set of metal and wooden rods;
- motor 775 DC, as in the photo.
A homemade jigsaw made of wood is made in several stages:
- They take multilayer plywood and cut out a profile in the shape of the letter P. The width of the workpiece should be 10 cm, and the length - 15 cm. At the ends of the horizontal sides, recesses are formed in the form of grooves of the same depth. A notch is also made at the bottom end. These grooves are needed in order to mix the file - then the jigsaw machine will work fine.
- Set the slider in the shape of the letter L to the farthest end. Next, cut a groove 2 cm long at the end of the piece running vertically. In width, it should correspond to the file, and in depth it should reach the midline of the section.
- Next, you need to step back from the slot 0.5 cm, make a slot in the transverse direction. Its width should correspond to the diameter of the pin. Then the do-it-yourself electric jigsaw will cope with all the functions.
- The file is fixed in the slots that run along the sliders. The pins must be installed in the slots across.
- One of the components of a do-it-yourself desktop jigsaw are sliders, in which a file has already been installed. Now they should put the horizontal parts of the workpiece in the form of the letter P. Moreover, the sliders should normally move in the vertical direction, that is, up and down.
- A wooden rod is inserted into the hole of the first slider - it will enter freely, after which it is necessary to fix it with tension. Next, they put a spring, which will have to return the file during operation. These are the basic tools for a jigsaw.
- The result should be such a design according to the drawings of a jigsaw with your own hands.
- A homemade electric jigsaw is powered by an electric motor 775 VS with a voltage of 12 V. It is attached with 2 screws. In the groove of the bracket, located on top, put the lower part of the workpiece in the form of the letter P (they need to be glued). Thanks to this, the slider will move freely along the groove.
- Do-it-yourself homemade electric jigsaw works fine with a stabilizer. To do this, a latch should be glued to the bracket.
- As a result, the workpiece should look like this.
- A wooden disk with a hole in the center is placed on the engine shaft and it is rigidly attached to the edges with a pin.
- It is clear how to make a jigsaw on wood with your own hands. Now it remains to check it. To do this, you need to glue the desktop from a piece of plywood and put the file in the center through the slot that runs across.
Metal jigsaw
By analogy with the first model, you can understand how to make a jigsaw from metal parts. For this you will need the following materials:
- metal circle - it will serve as a desktop;
- U-shaped blank made of steel 4 mm;
- profile with cut;
- mount and drive.
If we consider what can be done from a jigsaw with our own hands, it’s really possible to name a lot of items. It can be any figures, carved wood elements. Instructions for making this tool:
- Cut a hole in the profile.
- Exactly the same hole is formed in the U-shaped blank. This will help you understand how to make a jigsaw, securely connecting all the details.
- Connect both parts with a bolt.
- Weld a special platform, as shown in the photo.
- The result should look something like this - this is a do-it-yourself jigsaw blank on wood.
- Drill 2 holes on each side of the U-shaped workpiece.
- Insert bolts and tighten nuts.
- Assemble the structure and fasten with bolts. It turns out a desktop jigsaw with your own hands, assembled according to the drawings.
- Insert a nail file and fix with bolts as shown below.
- Saw a hole in the center of the metal circle and insert a file to make a desktop surface.
- Fix the motor from below - it is from it that the jigsaw will work with your own hands.
- An eccentric is placed on the reverse side of the engine, fixed through a pre-made hole.
- Make one turn of wire around the eccentric.
- Make a hole and insert one piece of wire.
- Form a loop and bite off the excess part of the wire.
- This is what the finished email looks like. do-it-yourself jigsaw mounted on the table.
After that, you need to test the tool. Next, you can figure out how to make a machine or other equipment out of a jigsaw. During operation, you should pay attention to how freely the file moves, with what accuracy it makes cuts. First, draft blanks are made, and then you can proceed to real tasks.
