Wood Band Saw

A band saw for wood is a necessary tool in a carpenter's workshop. With the help of such a machine, you can make straight and curved cuts. Evenly cut a wooden blank or cut along the contour of a drawing, all this can be done on such a machine.
The main part of such a machine is a band saw, which is a closed steel strip. On one side of her teeth are located.
It was such a machine that our author decided to make.

Tools and materials.
band saw;
10mm plywood sheet;
two car pumps;
bearings;
1.5 kW engine .;
300μF capacitors .;
profile pipe and corner of different sizes;
welding machine;

fasteners.

He cut 3 circles with a diameter of 30 cm from plywood 10 mm thick. He glued them together. Cutting out a strip of rubber from an old car camera, it pasted a wheel around it in a circle.
In the same way, I cut a shaft mount from plywood and fastened it to the wheel. The shaft was taken from an old automobile pump from a VAZ 2109.
From a profile pipe by homemade made a bed. So that the saw would not jump off the wheel, I installed a guide, making it from plywood and fixing it on a profile pipe.
Made of the twentieth pipe, angle and long bolts the centering and tensioning mechanism. By twisting the bolts, you can change the wheel position up and down, left and right. Secured the wheel by welding the pump to the centering mechanism. Further, it makes a guide from plywood and bearings. Cutting out the U-shaped base from plywood with the help of bolts and washers, fixes two bearings on it and fastens the guide to the bed stand.Then he makes the lower part of the machine. There is a motor at the bottom, so you need to cut and glue two wheels, one the same as the top and the second of a smaller diameter for the drive belt. Then the drive wheel is fixed on the working and the bearing shaft of the pump is already attached to it. Since we do not need to adjust the position of the saw below, the author’s pump gear, using argon welding, tightly welds to the bed.
Taking a 1.5 kW engine, it collects 300 microfarad capacitors for it.
Installs the engine on the bed, puts the belt.
He took a band saw for cutting meat and improved it by cutting off every third tooth. This gave an increase in speed and power.
After the band saw is installed on the impellers, you can install the countertop. It must be collapsible in order to change the saw.
