What is the difference between a jigsaw and an orbital jigsaw?
A standard action jigsaw moves the jigsaw blade solely in an up-and-down motion, while in an orbital-action jigsaw the blade moves slightly forward and into the workpiece on the upswing, then slightly backward on the downstroke as the blade resets for the next cutting stroke.
The Orbital Jig Saw uses a reciprocating or elliptical motion to saw through material depending on the use. It can be used to make straight or curved cuts.
Compared to jigsaws without orbital action the saw blades of pendulum action jigsaws can accomplish more than just a straight vertical cut. The variably adjustable pendulum action reduces the effort required for the forward movement thus allowing a quicker sawing progress.
There are two main types of electric jigsaws, those that are powered by mains electricity and cordless models that are driven by battery. Pneumatic jigsaws are also available, which run on compressed air, although these are rarely used.
A straight stroke is good for certain types of cuts like scrolling in wood or for cutting hard materials like steel. Orbital action, however, moves the blade in a slightly circular motion as it moves in and out of the tool.
A jigsaw puzzle (with context, often just puzzle) is a tiling puzzle that requires the assembly of often irregularly shaped interlocking and mosaiced pieces, each of which typically has a portion of a picture. When assembled, the puzzle pieces produce a complete picture.
A popular strategy is to put the edges of the puzzle together first because, with one straight edge, the pieces are easier to identify and put together. “There isn't a single strategy that will work for 100 percent of puzzles, but in the majority of cases, it is easiest to start with the edge,” McLeod says.
You will find puzzles of every different kind such as fine art jigsaw puzzles, animal puzzles, transportation puzzles, fantasy puzzles, mystery jigsaw puzzles, nostalgia jigsaw puzzles, landscape puzzles, humor puzzles, and many, many other sorts of jigsaw puzzle subjects.
If you're looking to do some serious work and need to cut through boards quickly, then a circular saw is the better option for you. But if you're working on more intricate shapes or detailed number cutting, then a jigsaw is going to be your best bet.
Jigsaw Speed
Medium – a mid-range cutting speed of 1,500 to 2,000 strokes per minute makes the jig suitable for cutting plastics and non-ferrous materials. Fast – jigsaws with a fast cut speed setting of over 2,000 strokes per minute are exclusively suited to cutting wood.
What was the original name for jigsaw?
The jigsaw was invented in 1855. It was a vertical reciprocating saw with a treadle to operate the blade. It was also known as a fretsaw or scrollsaw.
And whether you call them jigsaws, jig saws, or saber saws, they're all children of the scroll saw and do pretty much the same thing: make nice curved cuts in wood (as well as plastic, metal, and almost any other material).
A circular saw is mostly used for fast, accurate cutting of straight lines. It excels in making long cuts in thicker materials. Circular saws are mainly used for wood, although they can also cut other materials – in some cases using a special saw blade.
A jigsaw is the most versatile kind of saw. It can accurately cut both straight lines and curves. Especially for sawing curves, a jigsaw is clearly the best option. A jigsaw can use a wide variety of blades, optimized for different materials, accuracy, speed and curves.
The most difficult puzzles do have certain features, however: Repeating patterns. Monochromatic color schemes.
Good quality puzzles mean that the image on the pieces aren't grainy, and won't peel off the tops of the pieces. The cardboard of the pieces should be durable enough not to rip at the sides.
1000 Piece Jigsaw Puzzles
Most popular with puzzlers, an 1000 piece jigsaw puzzle is a large image that has been cut into approximately 1000 pieces!

A jigsaw is often used upside down, especially for neat scribe cuts and the like.
Jigsaws are ideal for cutting curves and complex shapes in wood (Photo 1). They also work well for making short crosscuts on a board (Photo 2) and finishing inside corner cuts (Photo 3) that you start with a circular saw. Jigsaws are not good for making fast, long, straight cuts. Use a circular saw instead.
Which side do you cut a jigsaw?
Most jigsaw blades cut on the upstroke, so chips and splinters occur mostly on the top of the wood. So if you value one side of a board more than the other, make sure you keep the good side face down, and mark and cut the less important side.

This happens most frequently when you're cutting curves or trying to force the saw to move through the material faster than it wants to go. Slowing down and “steering” the saw, rather than forcing it onward as fast as it will go, will almost always yield a cut at a more consistent angle to the surface of the material.
Jigsaw Basics
The up-and-down motion of a jigsaw blade is activated by pulling a trigger on the saw's handle. Most models are variable speed, meaning that the speed of the reciprocating action depends on how much pressure is placed on the trigger. Releasing the trigger will slow or stop the saw blade.
A reverse blade (teeth pointing downward) should be used on material with a pre-finished surface to reduce the risk of chipping or nicking during the cutting process.
Cut With the Good Side Down
Most jigsaw blades cut on the upstroke, so chips and splinters occur mostly on the top of the wood. So if you value one side of a board more than the other, make sure you keep the good side face down, and mark and cut the less important side.

Wasgij (which is Jigsaw spelled backwards) is a range of fun jigsaw puzzles. You have to use your imagination and the clues provided to piece together a completely different picture than what you see on the front of the box.
According to Johnson and Johnson (2000), there are also some disadvantages of using the jigsaw method, they are: 1) require some time to prepare students to learn how to work in groups, 2) require some time to make groups that each group has heterogeneity in their member ability, and 3) teacher should make special ...
2mm is a really good thickness for a puzzle, and higher-quality puzzles will be near that thickness. Obviously, the thicker the puzzle board the more consistency you will find when you assemble your creation. Equally, the pieces will be less likely to bend, fray or arrive bent from a rolling cut process.
