I remember when I was a kid, I liked to go to my favorite neighbor’s house and ask for Halloween candy His family will always send us a large package Microjig-the guardian of cutting tools safe job! happy life! The jig saw is the king of saws, uh, maybe maybe it is. My table saw may be the most frequently used tool in the woodworking room But it has a big flaw. It can only cut straight lines.
Without relying on CNC, laser, and other special equipment There are basically three ways to cut curves on wood Pull saw, very good at cutting intricate patterns on thin materials Usually used to make decorative patterns Band saw, probably the most commonly used tool for cutting curves in wood workshops But it is very expensive, it takes up space, and it has places beyond its power. The jig saw can handle almost all the curve cuts you can encounter Even better, it is more versatile, does not take up space, and is also cheaper. In fact, after so many years of carpentry career, I find myself using jig saws more often and band saws less It's very handy! Let's start by figuring out its name In the past, a jig saw was usually called a saber saw Today, saber saws usually refer to reciprocating saws It’s more often called "SawZall", which is a brand name Just like people sometimes call the electric circular saw "Skillsawz" (jeep's example is more vivid) However, the pull saw we are talking about today was called a jig saw in the past.
The jig saw cuts through the reciprocating movement of the small saw blade up and down The small saw blade makes it easy to cut smooth and accurate arcs It is more suitable than a band saw to cut holes in objects and the like Its biggest limitation is that it cannot cut very thick wood Normally, this is nothing. I rarely cut on wood larger than a 2×4 square Not to mention the curve The saw blade is placed on the so-called bottom plate or "shoes" There are many brands of jig saws that allow you to tilt the base plate to cut bevels But I can’t remember when I used this feature Most jig saws can be adjusted in speed This is more useful to prevent the wood from heating up and turning black when you are cutting the wood.
(Friction generates heat, you know) For pine cork, you can use the fastest speed And to deal with hardwoods, use a slower speed to reduce the possibility of blackening Usually there is a dial to adjust the speed Trigger under the mouth, the saw blade moves back and forth quickly I usually set the speed to the highest Then use the trigger to control the cutting speed Many jig saws have swing cutting settings When this function is turned on, the saw blade is reciprocating up and down at the same time Can also swing back and forth Is cutting more efficient Can increase the speed of cutting large workpieces The disadvantage is that this function will produce a lot of collapse I rarely use the swing cutting function Except occasionally when roughing workpieces If you have never touched a jigsaw before and are considering whether you should lose one I can narrow down your options Only buy jig saws with T-handle saw blades Be sure to confirm this before the prodigal In general, there are two types of saw blade handles Used to connect the saw blade to the jig saw The first common is the U-shaped handle It requires a hex wrench or other similar tools to install it on the jig saw I once had a saw like this, and it was a headache to use Sometimes the saw blade will fall off the jig saw When i cut No need to go to this trouble The second type is a T-handle saw blade No special tools needed to install them The saw blade can be installed in a few seconds And they are very strong The teeth of the jig saw are divided into up and down Wood on the side where the saw blade enters Will cut smoother I generally choose to go down Move down to cut Because I usually draw the cutting line on the better side of the board When the store sells more saw blades that cut upwards I don’t know why (because this can fix the jig saw on the board) Saw blades are also classified according to the number of teeth per unit length The less the number of teeth per unit length, the faster the cutting speed, the rougher the cut surface A saw blade with 10 teeth per inch is sufficient for most woodworking cuts This narrow saw blade with 20 teeth per inch can cut curves with very large arcs.
There are two issues to pay attention to when using a jig saw First, understand that the other end of the saw blade is unsupported Usually there is such a problem, but you turn too fast when cutting thick plates The saw blade is tilted so that the cutting surface is not perpendicular to the board surface Another thing to pay attention to is the length of the saw blade Make sure the saw blade is thicker than the workpiece you want to cut At least one inch (25.4mm) or more It’s also worth mentioning that the jig saw is really the safest power tool you may use.
Because the saw blade cuts under the wood and away from your fingers Fix the workpiece, I usually press it on the woodworking table with my hands Then cut it close to the edge of the woodworking table Sometimes the saw blade will cut to the woodworking table, but this is all a minor problem The way to start cutting with a jig saw is different from other saws I like to stick the saw blade to the workpiece before turning on the jig saw switch I think this is more precise If the saw blade has started to move, I move it towards the wood It usually sways left and right before trying to cut by the line Pay attention to keeping the saw floor close to the wood It's easy to lift the floor inadvertently Directly cause the edge of your cut surface to be not vertical The greater the curvature of the arc, the slower the cutting speed should be When the curvature is too large for the saw blade to turn Can be "carved" with a saw blade Cut to the cutting line with a saw blade once at a time Shake the saw blade left and right to remove the saw teeth Jig saw is one of the necessary tools for cutting holes and internal graphics These you can’t do with a band saw Just drill a hole, insert the saw blade, and start cutting If you need to cut a square hole, drill two holes in two diagonal corners, then connect them with a jig saw Cutting handles are equally efficient These are the kinds of jobs you can do with a jig saw Jig saw is a tool that should not be underestimated and ignored Hey there!
