Workshop band saw

The band saw is used for sawing wood products, plywood, fiberboard and MDF. There are varieties of it that can dissolve the logs on the boards. Professional band saw is most often used in large and medium-sized industries, where the speed and volume of material processing is important. But recently it has become popular among domestic craftsmen. With a band saw you can cut flat details of different thickness. Only in contrast to the jigsaw, both hands are free to work on this equipment, and a comfortable wide bed is offered for the movement of the workpiece. Most often, a band saw is used for cutting blanks of complex curved lines.

Making a band saw

Our machine is almost completely made of plywood. Therefore, for the base frame, we cut out four identical strips of plywood on a circular or jigsaw, as shown in the photo. It is advisable to take more thickness.

We cut out the grooves with the jig saw under the tensioner, the frame and the fastening of the drums. To make the holes and grooves more identical, you need to fasten the parts with a pair of clamps before cutting. As a result, we should have two pairs of different frames.

Now you need to glue the plywood with wood glue or PVA, and connect all parts of the base. For better pressing, you can compress the edges of the gluing clamps.

It should fit tightly into the groove as per the guides. We muffle it with a wooden plank so that the tension screw passes through it, securing it to the screws.

Remains of plywood will go to the drums. Marking them, make a hole under the shafts, and then cut out around the ring with a jig saw. Align and clean the edges of the plywood with sandpaper. To prevent the tape from slipping, the author preferred to tape the ends of the drums with tape.

Install the bearings at the shaft landing site. Two of them will be on both sides of the bed for a stationary drum. The remaining two are located on the tensioner. We also mount the locking bolt to secure the tensioner from the back of the bed.

We fix both drums on the frame so that they can move freely on the shafts without catching the machine body. We stretch the sawing tape, and adjust the tension with the help of a tensioner, at the same time fixing it with a stopper. Since the band saw is designed for vertical sawing, it is necessary to attach the lower platform from a wide board or a piece of plywood for stability. In the sawing area, you also need a desktop, on which workpieces will move.

The machine is ready, and you can try it in action. Clamp the lower shaft of the drum in a screwdriver or drill, and give the machine speed. Despite the small power of such a device, you can use it to cut parts from plywood, board, MDF or hardboard in your home workshop!

Practical advice

  • Turns of the machine should be selected by practical consideration, starting with small ones.
  • Watch the finger movement, since the most injuries in the carpentry are from such machines.
  • In large factory machines, the drums are protected with housings so that only the area of ​​the sawing table is open. It is also worthwhile to attach additional means of protection against breaking the tape to this device, which unfortunately are not indicated by the author.
