Build a Powered Hacksaw Like a Band Saw
These Popular Science plans are for building a powered hack saw, similar in function to a metal cutting band saw.
Hacksawing is the one onerous
shop job, and before the band saw there was no
inexpensive and readily available
power tool to ease the sweat. Commercially
made power hacksaws are costly and aren’t
found in most home shops.
Here, however, is a new answer.
several years of building and experimenting,
Popular Science experts have come
up with a simplified design for a homebuilt
power hacksaw at a cost that makes
it a practical power tool for any shop. All parts,
except for the motor land pulley drive, can
be assembled for less than $20. Any 1/2-hp. motor will run the machine. Any
standard 12” hacksaw blade can be used
In speed, accuracy, and capacity, the
saw rivals even big commercial machines.
It will cut stock of any size and shape up
to 3” high and 4” wide. In tests, it proved
so precise it sliced off disks from a solid
steel bar as thin as .050”.
The secret of the saw’s low cost is the
use of stock materials plus a pair of old
automobile connecting rods for the main
rocker arms-the heart of the machine.
Rocker-arm action is key to the saw’s
simplicity and accuracy. It keeps the
blade rigid and at the same time lets it
move back and forth parallel to the base.
