hacksaw, handles & blades - no, you don\'t know how to use one
Almost everyone has one and you need to buy one if you don\'t.
The Hacksaw is cheap and very economical to use.
But most of you have never used it because once you tried to use it things didn\'t go well.
You break the hacksaw blade, the blade keeps falling off the handle, or it\'s stuck all the time on the part you\'re trying to cut.
If you really manage to cut this piece off, it will take forever and the cut part will bend.
The main reason most people are having trouble sawing metal with a hacksaw is: you got the blade wrong and you didn\'t use a sharp blade. There are too many bends in the blade. The number of teeth is very low for this project. You applied work to the saw that you didn\'t clip.
When you and I read this, I will cover each of these difficulties.
Saw and saw blades are designed to cut metal (
I will tell you how to use it to cut wood and plastic)
Most people find it very difficult and frustrating to cut metal.
Most of the time, the reason is that they really don\'t know how to use a metal hacksaw.
What is a hacksaw?
The Hacksaw is a metal frame used to fix tempered metal blades.
The blade is usually 1/2 high, most of which are 12 inch long.
Each end of the blade has a hole that can be inserted into the pin on the hacksaw.
The Hacksaw is designed to be cut on the push stroke. The handle (grip)
On the designed right saw, the angle is right, so when you pass the blade through the material you cut, you put a little pressure on the blade.
Although some people
The person who is called \"expert\" will tell you that if you put the blade back, you can put the blade on the hacksaw in another way.
Do you need a hacksaw?
You can cut almost anything with a hacksaw.
Although it is designed to cut metal, you can use it to cut plastic, wood, metal tubes, aluminum, copper and brass.
Cutting electrical pipes works very well (conduit), BMX (
Flexible metal tube)
Plastic water pipes ,(PVT & CVT)
There are even nuts and bolts.
You can use it to cut 2x4 with the right blade tile under pinch.
Set the saw to be cut. Step 1.
Determine which blade will be used to cut the material. Use a 32 t. p. i.
Conduit blades, 18-tooth blades for cutting bolts or plastic pipes, and 8-tooth blades for Wood.
In practice, you want to have at least three teeth in contact with the material at any time.
If the depth of the cut exceeds the depth of the blade, use the blade with wavy teeth.
The wave blade leaves a wider groove (kerf)
This prevents the blade from sticking to the groove you are cutting.
You can use it to cut the wood.
It will be a lot slower than a wood saw, but it will work if you don\'t have anything else.
Use the 8 or 10-tooth blade to mark the cutting line on the board horizontally and vertically.
Initial cutting using horizontal marks (groove)
And the vertical mark that keeps the cut straight.
Take a moment and don\'t put too much pressure on the hacksaw. Step 2.
Insert the blade to point the teeth to the front.
If you can\'t see this, gently rub the teeth of the blade with your fingers.
You will feel the teeth \"catching\" your fingers.
When you push the saw, put the blade in your hand.
The hole of the blade enters the pin at the bottom of the frame.
Many hacksaw are designed with blades of different lengths, so if you have an adjustable frame you may have to shorten or lengthen the frame to fit your blade.
The teeth should try to \"catch\" your fingers when pushed.
The blade should be replaced if it does not feel sharp and is blunt.
The blades are cheap so don\'t be afraid to replace them. Step 3.
Tighten the thumb screw until you can\'t turn it with your hand (Hand tight)
This tension on the blade should prevent the blade from bending when cutting.
Sometimes when there is a problem with my blade falling off, I tighten 1/4 more with pliers.
Okay, let\'s cut something.
I will use metal tubes in this example.
Cutting is easy and once you have a little experience using a hacksaw, cutting the metal becomes a breeze.
To actually use a hacksaw, you need to clamp your work.
I have a vise on the workbench I usually use.
If you don\'t have a vise, screw 2x4 onto your bench and lean the tube against 2x4 with your left hand.
Use a vise or clip to secure the metal you want to cut if possible. Step 1.
To use the Hacksaw correctly, hold the frame with both hands. (
I am right hand so I hold the handle with my right hand and hold the other end of the saw with my left hand. )
Hold the hacksaw and let your right index finger point to the front to help guide the saw.
When you push the blade (forward stroke)
Guide the saw with your left hand so it can be cut straight.
Do not apply pressure with your left hand, just use it to guide your wound.
Use most blades.
If you apply pressure on the forward stroke with your left hand, the teeth will usually catch too much and the Saw will \"stick \".
The Hacksaw handle recline again, giving you proper downward pressure on the blade. Step 2.
When you reach the end of the previous trip, stop and pull the saw back with your right hand.
When you pull back, do not apply any pressure with your right hand. (
It cuts only in the forward direction and puts pressure on the return trip and will only wear the blade prematurely).
A lot of teachers will ask you to lift the saw on your return trip so you don\'t damage the blade.
When you cut, move your body forward and backward, press the forward itinerary and relax in the return itinerary. Step 3.
Repeat it until you see everything in the pipe.
With a little practice, you can cut it every second.
Don\'t scratch faster than this because it will generate too much heat and wear the blade too early again.
Don\'t put too much pressure on the blade.
Before you feel how much pressure you can apply, you may have to break one or two blades.
Don\'t worry, they\'re cheap.
Don\'t look too fast, because it will also cause the blade to break.
Always check to make sure the blade is tightly fixed in the frame. Reviews.
Or don\'t buy at Wally world, believe it or not, I can tell you more about using a hacksaw, but that\'s enough for you to cut properly.
Buy the good quality steel saw I recommend on my website.
Even the cheap ones I recommend, the quality is good and will last for a few years.
With the quality, it won\'t take long for you to use it well.
Don\'t buy cheap at the local dollar store. Why?
The Hacksaw handle must be strong enough to properly stretch the blade, and the cheap Hacksaw handle can only give you years of frustration.
You can also buy a tilted saw with a handle, just like Stanley 150565.
Some hacksaw have a straight handle that is hard to use for beginners.
The blade is cheap, so buy a box with at least two \"teeth\" numbers (
32 teeth for metal ducts, 18 teeth for solid steel, plastic pipes and general use.
But don\'t buy cheap blades.
The cheap blades are too brittle and you end up breaking a lot of them.
A good hacksaw blade is cut by itself and your pressure is small, so replace the blade once it gets dim.
To determine if the blade is dull, pull your finger over the blade.
If the tooth is still sharp, it will try to \"catch\" your finger.
Not a blunt blade.
I prefer Milwaukee blades because they bend and do not break compared to cheap ones and last for a long time.
Even better, buy two cheap hacksaws and keep different blades on each.
Dull, worn blade cutting items require a lot of work, so replace the blade as often as a normal knife or blade.
