cutting curves with a jigsaw
Let\'s figure out some vocabulary first so that we are all on the same page when we use the word \"jigsaw.
\"It\'s a bit confusing, but the traditional\" jigsaw puzzle \"was originally cut out on a\" reel saw \"that was once called a\" jigsaw puzzle.
Today, the word \"Jigsaw\" refers to a hand.
Handheld portable woodworking power tools, while the term \"roller saw\" refers to fixed woodworking machinery.
Another way vacuum to look at it is that in the case of a puzzle, the tool is taken to the workpiece, and in the case of rolling, the workpiece is taken to the machine.
Another name for the jigsaw puzzle is \"military knife saw \".
\"I used the puzzle for longer than I wanted to admit.
I found the first one lying in my childhood basement in my dad\'s woodworking shop.
A few years later, I bought a cheap one from Sears.
That machine gave me the quick convenience of all the puzzles provided, but never-
The current and annoying problem with no clear solution: first, the blades do not have a guide, so they habitually deviate from the cutting line, especially when I try to track the curved pencil line.
Second, when cutting the curve with a thick material, the jigsaw blade bends to the outside of the curve.
Third, the early jig saws had no orbital pendulum action, so they would be loaded and burned in thick materials.
A screwdriver is required to replace the blade and you must be careful not to lose the fixing screw. Today\'s top-
High quality puzzles eliminate all of these problems, a huge improvement compared to earlier models.
I will limit my presentation to high quality puzzles as there are still cutting rate models for the issues I just talked about.
Having said that, here are the most important things that should appear in your next puzzle: at the top of my list is the theme of blade tracking and blade guide.
Take a closer look at how each puzzle maker responds to these challenges, as it is unlikely that you will have a chance to try before purchasing the next puzzle.
Looking for details: some manufacturers have simply said something like \"excellent blade tracking\" without stating how this is done.
The others are convincing descriptions.
Another problem with all the puzzles is the wood split.
Most, but not all of the puzzle blades are cut on the upward stroke, which means that the cut usually happens on the good side of the board or plywood.
Split can be reduced in two ways :(1)fine-Cutting blades and (2)anti-
The fragment insert installed in the saw foot next to each side of the blade. Fine-
Cutting the blade is slow to cut, so if speed is required and you are using a more positive-
Jigsaw blade with teeth, unless you want to polish and/or crush the fragment area later, the fragment insertion is absolutely necessary.
Repeated blade changes are a fact of life for all puzzles.
To support production efficiency, the process should be as fast and easy as possible.
The era of screwdrivers, Allen wrenches and fixing screws has passed.
You want a jigsaw puzzle that will allow you to quickly change the blade. .
If you are healthy and want to minimize dust in the air in the work area, you may want to collect dust by installing a vacuum hose on the puzzle.
In this case, check the dust port and make sure it is compatible with the vacuum hose.
Personally, I usually wear a good dust cover, thus avoiding the annoyance of dragging the vacuum hose along with the saw when I try to turn the machine along the curve.
I mentioned the orbital pendulum action above and I wouldn\'t even consider buying a puzzle that doesn\'t include it.
My first track machine is the Bosch bucket grip model.
When I was on a business trip, I was allowed to try out one at a woodworking shop and it went back to Hawaii in my suitcase.
That\'s why: the salesman has a slate of eight.
And encouraged me to cut some curves in it.
There are four track settings on this machine, the first one is \"no track action\", and each one after that is more radical than before.
I started cutting as the track was in the \"off\" position.
As I expected, the 2 machine slowly went through the cut and I realized that if I pushed hard, the jigsaw blade would either burn or break.
Then, at the suggestion of the salesman, I put the track rod in the most aggressive \"4\" position and cut it again.
The blade runs through thick oak trees like butter.
There is more division than before, but not so much. Sold, American!
One side advantage of the oscillating puzzle is the greater blade life.
When the blade is stuck inside the cut, it has nowhere to go to dissipate heat.
The pendulum action makes the blade go in and out of the cutting surface, allowing cold air to come in when the blade is temporarily away from cutting.
At the same time, the accumulated sawdust is allowed to fall off from the cutting, so the blade always cuts new wood, not the old sawdust.
That\'s why it can be colder faster.
Most good puzzles, but not all have electronic speed control (ESC)
This is an important thing.
ESC is like vacuum the cruise control device on your car: it maintains a constant speed as the load conditions change.
The harder you push the puzzle, the more power you automatically send to the motor, so that the saw blade does not slow down.
The analogy is that your car is up the hill on cruise control.
Today, many jigs saw have two different body styles: Barrel Grip and top griphandle (
Sometimes D-handle).
I own both products and I personally prefer the bucket grip style as it is easier to control when doing fine cutting.
Just like using a router or any manual tool, the low center of gravity and a strong grip are equivalent to better control. With a top-
Dealing with puzzles, your hands are on the top of higher machines, and the tendency to tilt is even greater.
With the bucket grip puzzle, the center of gravity is as low as possible.
There is a knob at the top of the jigsaw blade that will give your other hand better control.
Large and round barrels are easier to catch than thin 2 D-Handle.
Jigsaw puzzle manufacturers usually use the number of amps instead of horsepower to indicate the power of the motor.
This is good because amps reflect actual power more reliably than horsepower.
The larger the current, the more important the power and power are when cutting thick or dense materials.
The speed of the jigsaw blade is represented by \"strokes per minute\" or \"SPM.
\"The more the better.
Cutting depth is something you want to consider when dealing with materials that are thick or dense.
In soft wood, the cutting depth refers to the maximum distance between the base tooth on the blade and the foot plate of the puzzle when the blade is fully extended.
In metal, plastic or other materials, the depth of cutting depends on the ability of the saw blade and blade to cut dense or wear-resistant materials.
Jigsaws are often used to cut expensive and refined materials such as veneer plywood and typical steel foot boards, which may leave scratches when it is dragged along the back of the blade.
Some manufacturers offer coated foot boards, some offer \"shoes\" for foot boards, and some do not pay attention to this issue at all.
Please note this feature if you cut delicate materials that are easily damaged (or lack of it. )
The weight of the machine should be considered next. My knee-
The response to the jerk is to look for the lightest machine so I don\'t get so tired during the long cutting process.
The second idea is that the weight is light and far from its advantage, say, the impact Drive or the drill, because the weight of the puzzle is almost always pressed on the material being cut.
In addition, light weight may mean that builders slide over building materials and may replace metal with plastic parts to save costs.
The travel length is the distance that moves up and down when the serration is cut.
This is almost universal.
Inches, so this is not a useful number when comparing designs from different manufacturers.
Generally speaking, the longer the trip, the faster the cut, the shorter the trip, the smoother the cut.
Jigsaws can be cut with a Beeline, usually up to 45 degrees from the vertical (left and right.
The more slopes, the thinner the material that can be cut.
It can be tricky or simple to adjust the bevel.
Some puzzles require you to use a screwdriver, a hex wrench, or an Allen wrench to loosen or tighten the fixing screw for the fixed foot.
Other puzzles are designed with a built-in adjustment mechanism
Therefore, no tools are required.
Choose the latter if possible, everything else is taken into account.
All the puzzles vibrate and make noise.
Obviously, the less vibration and noise the better.
Vibration is passed to the cutting point, affecting your ability to control the cutting.
More importantly, it will be very tired when the vibration enters the operator\'s hands and arms.
Various puzzle makers have dealt with the problem in different ways, but the most common
Vibration technology is to \"balance\" the motor \".
The other way is to take the vibration-
Absorbing material on the outer surface of the machine in direct contact with the hand (s)
Operator\'s
Of course, the padding does not minimize the vibration that is passed to the jigsaw blade when cutting.
Noise reduction varies depending on the machine design, the only way to make this comparison is to run the puzzle you are considering buying.
Some puzzles are equipped with transmission wheels to set the maximum speed of the tool in order to get better cutting results in different materials.
This is different from the speed control of the variable speed trigger.
Full speed on the trigger will always be limited by variable speed wheel settings.
Most puzzle triggers have locks
Because holding the trigger all day can actually make your hands numb.
No trigger for barrel grip but use lock-
It\'s on the thumb switch.
If you set the speed change to half speed
Speed, you lock the trigger or the thumb switch, you will get half
Before moving the settings on the wheel, at the speed at which the deflection is fully triggered.
Most of the jigsaws come with some sort of hair dryer to keep the chip out of the cutting line.
The blower on the early machine is located in half
Between the operator\'s chin and nose.
Some manufacturers install blower nozzles near the cutting point and others on top of the machine.
Some have adjustable nozzles.
It\'s important to have effective chips and dust removal so you can see where you should cut.
Another tool that helps with the vision of a clear cutting line is a built-in-in light.
LED lights are the best because they are bright white and last almost forever.
Just in case, see if they are replaceable and available.
There are several types of jigsaw blades for sale and you have to use the kind that your jigsaw design accepts.
Different blade types. The T-
I prefer the handle as it is locked in the saw post.
Other types include Donald and U-shank.
Once you know what type of blade your puzzle needs, be sure to check the availability of the blade design that suits the work you are going to do.
The rough cutting blade provides power through thick and rough material, but leaves a lot of pieces. Fine-
The cut blade has more teeth and leaves less and less debris, but the cutting speed is slow and the length is usually shorter.
They may also be thinner (front to back)
In order to make the sharp curve closer.
They break more easily than rough blades.
Metal cutting blades are also required.
Use these only for metals as they do not cut wood very easily and they load and burn in the wood.
On the other hand, a piece of wood --
The cutting blade will not be able to cut the metal effectively.
Depending on the manufacturer, there are many other special types of jigsaw blades to choose from.
Make sure you always have enough extra blades on hand to
