All about Rasp's File's and Riffler's
A rasp is a piece of steel with little teeth cut in all over the surface of the tool. Rasps superficially resemble files, which have long teeth running the width of the file. Files are very useful and popular tools, but their woodworking use is mostly restricted to sharpening woodworking tools. They're basically used for metalwork, whereas rasps are used on wood and stone.
In woodworking the word Rasp is used to denote the entire family of the tool when are talking generally aobut the use of the tool. When the particular details matter we rasps to mean a rasp with a handle at one end. The term riffler rasp or riffler is used to describe a type of rasp with teeth cit in both ends with an area to hold onto the middle. Rifflers can be either file cut with long lines of teeth or rasp cut with pointy teeth. Riffler rasp might be the better term to use.
Tools for a Basic Layout Kit
As we have already mentioned a try square, a ruler and a marking knife are essential layout tools. To complete our layout kit we will add a marking gauge, a mortising gauge, a bevel gauge, a protractor, a set of dividers and trammels used for circles. As our instructor told us "Flawed measurements will plague a project at every stage.
