The combination square tool can be used for multiple purposes in engineering , also for woodworking, stonemasonry and all types of metalworking. It is composed of a ruled blade and one or more interchangeable heads that may be affixed to it. The most common head is the standard or square head which is used to lay out or check right and 45° angles. Combination square was invented in 1883 by Mr Laroy S. Starrett . Hence the company “Starrett” was formed, the combination square continues to be a commonplace tool in home workshops, construction jobsites and metalworking.
An essential tool in all fitter’s or machinist toolbox;
· Measuring angles — A combination square can reliably measure 90° and 45° angles. The 45° angle is used commonly in creating mitre joints.
· Determining flatness — When working, the first step is to designate a reference surface on a board which is known as a datum edge. The rest of the workpiece is measured from the datum
· Measuring the centre of a circular bar or dowel. The rule is assembled through the centre of the centre square, the two cast iron legs of the centre square are then placed against the outside of the bar (dowel) allowing a centre line to be scribed alongside the ruler. Perform this action at two locations and the intersecting lines will approximate the centre 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.
· It is used to find the centre of the round jobs.
· for measuring angles.
In engineering & 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.
Combination squares or combination square sets are avail. at Miller’s Tooling in a range of quality & prices. Combination square only can be purchased or as a set. Generally we can supply missing parts ( ie; protractors, or centre squares, etc on their own).
