Understanding the terms that are used in woodworking can help you get the right tools, including the best band saws for resawing. The terms ripping and resawing are usually used interchangeably, but they are not the same thing. However it is important that you realize that whilst resawing is a type of rip cut, it is not all rip cuts that are resaws.
Resawing refers to the action of slicing a piece of wood right down its thickness, to end up with two slices. Meanwhile, rip cutting is when you cut across the width of the wood. Ripping is about reducing the with, but the thickness and length do not change. Whereas resawing is about reducing the thickness whilst the length and width remain the same.
Woodworkers will resaw wood when they need a thinner version of the wood that they are working on. It is especially helpful when you are working on expensive wood that is thicker than you need and you do not want to waste a bit of it.
Most table saws are compatible with dado blades however it is not all that is. Portable table saws especially, generally have short arbors that do not safely accommodate a full stacked dado blade set. You will not face any problems if you are using a single saw blade. however, when you are trying to use a stacked dado blade, you will find that there is not enough thread to allow the nut to be safely threaded onto the arbor.
