Saws are one of the most common hand tools. Almost everyone has an owner, and if there is no one, one has to buy one. Saws are cheap and very economical. But you never use the most, because once you tried to use things. He broke the blade, the blade dropped from the handle or left in the piece he was trying to cut. If you managed to get the piece, it lasted forever, and the cut was curved.
Most people have difficulty with sawing with metal saws:
The blade is bad
Not using sharp blade
Too much flex on the blade
] The number of teeth is low for the project
Too puts a lot of pressure on the saw
Do not squeeze the work.
I cover all of these difficulties as you and I go through the article.
Sawing saws and saw blades are designed for cutting metals (I'll tell you how to cut wood and plastic) and most people are very heavy and frustrating. Most of the time is that they do not really know how to use metal saws.
What is a saw?
The saw saw is a metal frame that holds a slender metal plate. The blades are typically 1/2 inch high and most of them are 12 cm long. There is a hole at each end of the blade that fits the saw blade. Saw saws are designed to cut push strokes. The handle (handle) on the properly designed saw is just right-handed, so it puts a little pressure on the blade when pushing through the cut material. Although some so-called "experts" will say that the blade can be positioned differently, the blade does not work well when the blade is backward.
You need a saw
You can cut almost anything with a saw. Despite being designed for metal cutting, you can use it to cut plastic, wood, metal tubes, aluminum, copper and brass. It works very well for cutting electric pipes (pipelines), BMX (flexible metal tubes), plastic water pipes (PVT and CVT) and even nuts and screws. You can use a pinch and the right shovel with a porcelain plate to cut a 2X4.
Adjusting the Saw Saw to Cut
1. Step 3: Determine which blade to use for cutting the material. Use a 32-tp blade for a pipe, a toothpick 18 for cutting a screw or plastic tube and a tooth 8 for the wood. In practice, you want to contact at least three teeth at any time. When cutting a deer like a blade, use a blade that contains wavy teeth. The wavy blades leave a wider gap (kerf) that retains the blade in the cut groove.
Cutting wood. It will be much slower than a saw, but it will work if there is no other. Use 8 or 10 toothpicks and mark the cut line on the board both horizontally and vertically. Use the horizontal mark to make the first cut (groove) and the vertical mark, so that the cut is straight. Take the time and don't put a great deal of pressure on the saw.
2nd Step Insert the blade so that the teeth point forward. If you don't see this, gently rub your finger over the teeth of the blade.
Feels that the teeth grip the finger. Place the blade by grasping the saw. The blade holes are placed in the pins at the bottom of the frame. Many saw blades are designed to use blades of different lengths, so if you have an adjustable frame, you may need to shorten or extend the frame to fit the blade.
Teeth must try to grasp the finger. If you don't feel sharp, the blade is boring and needs to be replaced. Blades are cheap, so don't be afraid to replace them.
3rd Step Pull the thumb screw until you can turn it with your hand. Sometimes, when I have problems with the blade, I'll pull a 1/4 turn with a pliers.
Ok, cut something.
I use a metal tube for this example. Easy to cut, and if you get a little experience using the saw, you will be cutting the metal.
To be able to use the blade really well, you need to tighten your work. I have a job I usually use.
If you do not have a turn, twist 2X4 onto the bench and hold the tube with 2X4 with your left hand. If possible, use a peg or clamp to fix the metal to be cut.
first Step 2: Hold the frame with both hands to use the saw blade properly. (I have a better hand so I grab the handle with my right hand and use my left hand to hold the other end of the saw.) Hold the saw blade so that the right index finger points forward to help the saw. When pushing the blade (pre-blow), use your left hand to guide the saw straight. DO NOT use the left pressure, just use it to control the cut. Use most of the blade. If you put pressure on the front stroke with your left hand, the teeth will usually catch too much and the saw will "stick". Again, the handle of the blade is angled to apply pressure to the blade.
2nd Step 1: If you reach the end of the front stroke, stop and pull the saw back with your right hand. Do not use any pressure with your right hand as soon as you retract. (It only cuts in the forward direction and the pressure on the return stroke is only used by the disk before the time). Many teachers do it to lift the saw backwards, so it doesn't destroy the blade. Move your body forward and backward as you cut, press forward, and fold down on the return side.
3rd step. Repeat this until you see the tube all the way. With a little exercise, about a second. Do not schedule faster than it is because it creates too much heat and the blade will wear out again.
Do not apply too much pressure to the blade. You may have to break a blade or two before you understand how much pressure can be achieved. Don't worry, cheap. Don't look too fast because that blade can break. Always check that the blade is firmly attached to the frame.
Reviews Or don't buy one at Wally World
Believe it or not, I could say that by using a saw, I can say much more, but that's enough to cut it properly. Buy a good quality blade that I recommend on my website. Even the cheap I recommend is of good quality and lasts for years. Quality sawing will not last long before you use it well.
DO NOT buy cheap at the local dollar store. Why? The chainsaw handle should be strong enough to allow the blade to be properly tensioned, and the cheaper ones will give nothing but frustration for years. You can also buy a Stanley 150565 tilt handle. Some saws have a straight handle and are very difficult for beginners.
Blades are cheap, so they buy at least two "teeth" numbers (32 teeth for metal tube and 18 teeth for solid steel, plastic tube and general use. Fragile and finally a lot The good saw blade cuts its own and exerts very little pressure so replace blades as they become cloudy, if they are still sharp, teeth try to grasp your finger.
