Discussing get some conditions right first so we are both clear about what we are talking about. It’s a little confusing but traditional “jigsaw puzzles” were actually cut out on a “scroll saw” which used to be called a “jigsaw”. Today, the word “jigsaw” refers to a hand-held lightweight woodworking electric power tool as the term “scroll saw” identifies a fixed woodworking machine. Another way to look at it that in the matter of a jigsaw, the tool is helped bring to the workpiece and in the case of the scroll saw the workpiece is brought to the machine. Another name for a jigsaw is “sabre saw. inches Best Product Review
We’ve been using jigsaws much longer than I’d like to admit. I discovered the first one lying around my dad’s woodworking shop in the basement of my childhood home. A few years after that, I actually purchased a cheap one from Sears. That jigsaw gave me the quick usefulness that all jigsaws provide but there were persistent and annoying problems without apparent solutions: 1st, The blades had no guides so they would always wander away from the cut line, in particular when I was trying to track curved pencil lines. Second, when cutting shape in thick material, the jigsaw blade would flex toward the exterior of curves. Third, early jigsaws did not have orbital pendulum action and so they would wrap and burn in thick materials. Changing blades required a screwdriver and you needed to be careful not to lose the collection screw.
Today’s top-quality jigsaws have eliminated all those problems and are, in contrast to the previous models, revolutionary. I will confine my remarks to better quality jigsaws since there are still discount basement models out there with the problems I recently outlined. Having said that, here will be the important things that you should be looking for in your next jigsaw:
At the top of my list will be the subjects of knife tracking and blade leads. Have a close look at how each jigsaw producer has approached these difficulties because you might be not heading to get a chance to test out your next jigsaw before buying it. Look for details: Some manufacturers simply say something like “superior knife tracking” without saying how this is accomplished. Other folks are convincingly descriptive.
An additional issue with all jigsaws is wood splintering. Many, but not all, jigsaw blades are designed to cut on the upwards stroke which means that the splintering often occurs on the good aspect of the board or plywood. Splintering can be minimized in two ways: (1) fine-cut blades and (2) anti-splinter inserts installed in the saw feet immediately adjacent to either side of the blade. Fine-cut blades cut slowly so if speed is a requirement and you are by using a more aggressively-toothed jigsaw blade, a splinter put in is a total necessity unless of course you plan to crushed stone and/or rout away the splintered area later.
Repeated blade changes are a well known fact of life with all jigsaws. In the interest of production efficiency, this technique should be as easily as possible. Gone are the days of screwdrivers, Allen wrenches and collection screws. You want a jigsaw that lets you pop blades in and out in rapid fashion.
If you are health conscious and wish to minimize airborne dust in your work area, you may want to acquire dust right at their source by connecting a vacuum hose to the jigsaw. If so, check for a dust port and make sure that it is compatible with your vacuum hose. Personally, I actually favor to wear a good dust mask and therefore avoid the inconvenience of dragging a vacuum hose pipe along with the jigsaw when I am striving to control the machine along curves.
I pointed out orbital pendulum action above and i also would not even consider buying a jigsaw without it. My first orbital machine was a Bosch gun barrel grip model. I was allowed to try one out in a woodworking store while I was on the business trip and it went home to Hawaii in my travel suitcase. Here’s why: The sales person had a piece of eight-quarter White Oak and encouraged me to lower some curves in it. There were four orbital settings on that machine with the first being “no orbital action” and each one after that being more aggressive than the main one before. With the orbit in the “off” position, I started a cut.? nternet site expected, the machine slowly strained through the cut and i also knew that if I pushed it any harder, the jigsaw blade would either lose or break. Then, at the suggestion of the salesman, I put the orbit lever in position “4, ” the most aggressive, to make another cut. The blade travelled through the thick Maple as if it were butter. There is somewhat more splintering than before but not really that much. Sold, American!
A side benefit for an varying jigsaw is extended cutting tool life. When a cutter is stuck inside a cut, it includes nowhere to go to dissipate the warmth. The pendulum action pivots the blade in and out of the slicing face, letting cool air in while the knife is momentarily positioned away from cut. At the same time, the accrued sawdust is allowed to drop-out of the minimize and so the blade is always cutting new wood, not old sawdust. That’s why it can go faster and cooler.
Most good jigsaws, but not all, have Electronic Speed Control (ESC) which is an important nicety. ESC is like the cruise control on your car: This maintains a frequent speed with changing load conditions. The harder you push the jigsaw, the more electric power is delivered automatically to the motor so that the saw cutting tool is not going to slow down. The analogy is your car on cruise control heading up a hill.
