Hacksaw, Handles & Blades – No, You Do not Know Easy methods to Use One
Hacksaws are one of the crucial widespread hand instruments. Almost everybody owns one, and if you do not have one, it’s worthwhile to purchase one. Hacksaws are cheap and really economical to make use of. However most of you by no means use it as a result of the one time you tried to make use of it issues did not go properly. You broke the hacksaw blade, the blade stored falling out of the deal with, or it stored getting caught within the piece you have been making an attempt to chop. When you did handle to get the piece reduce, it took ceaselessly and the minimize ended up crooked.
The primary causes most individuals have problem when sawing metallic with a hacksaw are:
You’ve the blade in incorrect
You are not utilizing a pointy blade
There’s an excessive amount of flex within the blade
The variety of tooth is to low for the undertaking
You’re placing an excessive amount of strain on the noticed
You do not clamp the work.
I’ll cowl every of those difficulties as you and I’m going by way of this text.
Hacksaws and hacksaw blades are designed to chop metallic (I’ll inform you how one can use it to chop wooden and plastic) and most of the people discover slicing metallic very troublesome and irritating. The rationale, more often than not, is that they do not actually know tips on how to use the metallic hacksaw.
What’s a Hacksaw?
A hacksaw is a metallic body designed to carry a tempered metallic blade. The blade is usually 1/2 inch excessive and nearly all of them are 12 inches lengthy. The blade has a gap on every finish that matches into pins on the hacksaw. Hacksaws are designed to chop on the push stroke. The deal with (grip) on a correctly designed noticed is angled good so you set somewhat strain on the blade once you push it via the fabric you’re slicing. Regardless that some so-called “specialists” will inform you that you could put the blade within the different approach a hacksaw doesn’t work nicely when you’ve got the blade in backwards.
Do you want a Hacksaw?
You possibly can reduce virtually something with a hacksaw. Though it was designed to chop metallic, you need to use it to chop plastic, wooden, metallic tubing, aluminum, copper, and brass. It really works very properly to chop electrical tubing (conduit), BMX (versatile metallic tubing), plastic water pipe, (PVT & CVT) and even nuts and bolts. You need to use it to chop a 2X4 in a pinch and with the appropriate blade porcelain tile.
Establishing the Hacksaw to Minimize.
Step 1. Decide which blade you’ll use to chop the fabric. Use a 32 t.p.i. blade for conduit, an 18 tooth blade for slicing off a bolt or plastic pipe and an eight tooth for wooden. In apply you need a minimum of three tooth in touch with the fabric at any time. In case you are chopping deeper than the depth of the blade use a blade that has wavy tooth. The wavy blade leaves a wider slot (kerf) that retains the blade from sticking within the groove you’re chopping.
You need to use it to chop wooden. It can minimize lots slower than a wooden noticed, however it works if you do not have anything. Use a eight or 10 tooth blade and mark the minimize line on the board each horizontally and vertically. Use the horizontal mark to make you preliminary reduce (groove) and the vertical mark to maintain your minimize straight. Take your time and do not put loads of strain on the hacksaw.
Step 2. Insert the blade in order that the tooth are pointing ahead. If you cannot see this, rub your finger gently over the tooth of the blade.
You’ll really feel the tooth “grip” your finger. Put the blade so it grips whenever you push the noticed. The holes of the blade go into the pins on the underside of the body. Many hacksaws are designed to take totally different size blades so when you have an adjustable body you’ll have to shorten or lengthen the body to suit your blade.
The tooth ought to attempt to “seize” your finger when pushed. If they do not really feel sharp, the blade is uninteresting and must be changed. Blades are cheap so do not be afraid to switch it.
Step three. Tighten the thumbscrew till you’ll be able to’t flip it together with your hand (Hand tight) This quantity of pressure on the blade ought to hold the blade from bowing as you narrow. Typically when I’m have issues with the blade falling off, I’ll tighten it one other 1/four flip with a pliers.
Okay, Let’s Reduce One thing.
I’m going to make use of a metallic pipe for this instance. It’s straightforward to chop and when you get a bit of expertise utilizing the hacksaw, chopping metallic shall be a breeze.
To actually use a hacksaw nicely you might want to clamp your work. I’ve a vise on a workbench that I often use.
If you do not have a vise, screw a 2X4 onto your bench and maintain the pipe towards the 2X4 together with your left hand. When attainable use a vise or clamp to safe the metallic you need to reduce.
Step 1. To make use of a hacksaw correctly, grip the body with each palms. (I’m proper handed so I seize the deal with with my proper hand and use my left hand to carry the opposite finish of the noticed.) Maintain the hacksaw in order that your proper hand index finger is pointing forward to assist information the noticed. As you push the blade (ahead stroke) use your left hand to information the noticed in order that it cuts straight. DO NOT use your left hand to use strain, simply use it to information your minimize. Use a lot of the blade. In case you apply strain on the ahead stroke together with your left hand the tooth will often seize an excessive amount of and the noticed will “stick”. Once more a hacksaw deal with is angled to provide the correct down strain on the blade.
Step 2. Whenever you get to the top of the ahead stroke, cease and pull the noticed again together with your proper hand. As you pull again do not apply any strain together with your proper hand. (It solely cuts within the ahead path and placing strain on the return stroke will simply put on out the blade prematurely). Loads of academics will make you carry the noticed on the return stroke so you do not destroy the blade. Transfer your physique ahead and again as you narrow, urgent on the ahead stroke and easing off on the return one.
Step three. Repeat this till you noticed throughout the pipe. With a bit of follow it is possible for you to to chop at about 1 stroke each second. Do not stroke any quicker than this as a result of it is going to create an excessive amount of warmth and once more put on out the blade prematurely.
Do not put an excessive amount of strain on the blade. You could have to interrupt a blade or two earlier than you get the texture of how a lot strain you possibly can apply. Don’t be concerned, they’re low cost. Do not noticed too shortly as that may trigger the blade to interrupt as properly. All the time verify to make it possible for the blade is secured tightly in its body.
Evaluations. Or Do not buy one at Wally World
Consider it or not, I might inform you much more about utilizing a hacksaw, however this is sufficient to get you slicing correctly. Purchase a superb high quality hacksaw I like to recommend on my web site. Even a budget one I like to recommend is sweet high quality and can final you years. With a top quality noticed it will not take lengthy earlier than you get good at utilizing one.
DON’T purchase an affordable one on the native greenback retailer. Why? The hacksaw deal with needs to be robust sufficient to maintain the blade tensioned appropriately and a budget ones offers you nothing however years of frustration. Additionally purchase a hacksaw with the deal with tilted just like the Stanley 150565. Some hacksaws have a straight deal with and are very arduous to make use of for a newbie.
Blades are low cost, so purchase a field of them in at the very least two “tooth” numbers (32 tooth for metallic conduit and 18 tooth for strong metal, plastic pipe and basic use. However do not buy low cost blades. A budget blades are too brittle and you’ll find yourself breaking numerous them. A superb hacksaw blade cuts on it is personal with little or no strain from you so change the blades as quickly as they get uninteresting. To inform if a blade is uninteresting pull your finger over the blade. Whether it is nonetheless sharp the tooth will attempt to “catch” in your finger. A uninteresting blade will not. I choose Milwaukee blades as a result of they’ll flex with out breaking, and final an extended, very long time in comparison with a budget blades. Higher but, purchase two cheap hacksaws and hold totally different blades on every. Uninteresting, worn blades take plenty of work to chop an merchandise, so change them as typically as you’d a utility knife or razor blade.
