Will need
- The metal blade is standard.
- Square tube, 10×10×500 mm.
- Two bolts for 6, and nuts for them
- Two 8mm bolts with wings (you can use regular nuts if you don’t have any with wings).
- Screwdriver for bolts.
- Pliers.
- Marker.
- Ruler.
- Drill.
- Drills for 3, 4, as well as a small cutting disc.
- The handle is from an old file.
Making mini hacksaws for metal
To begin with, you can make a canvas of the desired size. To do this, using a mini drill and a cutting disc, you need to divide the standard blade into two equal parts.
Also, it is necessary to round off the cut edges of the canvas and make the same holes in them as at the opposite ends. The result should be two completely identical fifteen-centimeter canvases.
You can drill the canvas with the most ordinary metal drill - the canvas will not burst. It's not so hard in the middle. During the manufacturing process at the factory, only the jagged edges are hardened in it using instantaneous induction heating, and the middle remains raw, flexible, and not at all brittle. Next, we measure and saw off two pieces of 90 mm each from the tube (I took a square one - it’s easier to work with).
Now we again measure 20 mm from these segments from each end.
You need to cut out the middle of them. Like this:
It is necessary to fit the sawn ends with pliers. Pull one end apart so that the main tube fits into it. The opposite - on the contrary, squeeze it so that the canvas is held in it.
We drill 3 mm holes in the flattened ends of both workpieces.
We insert the canvas into the flattened edges of the blanks and tighten them with 6 bolts.
We saw off 200-250 mm from the tube for the main frame-holder, and try on blanks with canvas for it.
We mark the places for the wing bolts with a marker, and drill through holes with a 4 mm drill.
We insert the bolts at 8 and tighten them with wings.
These wings are needed so that you can move or move apart the blade holders without keys and screwdrivers if you ever have a blade of greater or shorter length. Next, we make longitudinal cuts in the tail part of the main tube.
30 millimeters will be enough. Squeeze the sawn area with pliers.
We drive in the handle.
Well, the mini hacksaw is ready. A test can be done.
It cuts, of course, not as fast as a regular hacksaw, but for small objects, such as a rusty nail or screw, in a hard-to-reach place - just right! And, what a savings on canvases - they made two out of one! And if it is also double-sided, like mine, then you can use it four times before it becomes dull!
