# Combination square

A Combination Square consisting of the ruler, 45° holder, protractor and center square

A combination square is a tool used for multiple purposes in woodworking, stonemasonry and metalworking. It is composed of a ruled blade and one or more interchangeable heads that may be affixed to it.[1] The most common head is the standard or square head which is used to lay out or check right and 45° angles.[1]

## Uses

• Measuring angles — A combination square can reliably measure 90° and 45° angles. The 45° angle is used commonly in creating miter joints.
• Determining flatness — When working with wood the first step is to designate a reference surface on a board which is known as the face side. The rest of the workpiece is measured from the face side with the next surface being the face edge.
• Measuring the center of a circular bar or dowel. The rule is assembled through the center of the center square, the two cast iron legs of the center square are then placed against the outside of the bar (dowel) allowing a center line to be scribed alongside the ruler. Perform this action at two locations and the intersecting lines will approximate the center of the bar (dowel).
• Protractor head allows angles to be set and measured between the base and ruler.
• A rudimentary level for approximating level surfaces is incorporated in the protractor and also the 45° holder.
• By moving and setting the head, it can be used as a depth gauge or to transfer dimensions.
• Marking the work surface; with the included Scribe Point stored in a drilled hole in the Square Base.

In woodworking, the starting raw material is neither flat nor square, however, the end product such as a table must be flat and have corners and legs which are square.

In metalworking, it is useful for a wide variety of layout and setup tasks. When used correctly, a fairly high degree of precision can be achieved. One use would be setting large items at the required angle in machine vices, where the long reach of the ruler and firm, heavy base aid the process.

Invented by Laroy S. Starrett in 1878, the combination square continues to be a commonplace tool in home workshops, construction jobsites and metalworking

Lettris

Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.

boggle

Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !
