Starrett combination squares comprise a rule and one or more interchangeable heads which can be attached to the rule. The brand's combination squares feature a square head which comes equipped with a reversible lock bolt, scriber & spirit level. They also have a hardened steel, photo engraved blade featuring regular or satin chrome finish. Choose from a wide range of these combination squares, available in 300 mm, 18 inch and 24 inch blade lengths on Raptor Supplies.
Starrett combination squares are used for ensuring the integrity of a 90-degree angle, measuring a 45-degree angle, measuring the centre of a circular object, finding depth and evaluating simple distance measurements. Starrett combination squares can also be used to determine level and plumb using the spirit level vial.
Starrett combination squares consist of a rue-type blade attached to a handle. The handle is composed of two parts, a shoulder and an anvil. The shoulder is placed at an angle of 45 degrees against the blade, for the measurement and layout of mitres. The anvil is placed at a 90-degree angle between itself and the blade. The handle contains an adjustable knob that allows it to move horizontally along the edge of the ruler. A scriber and a vial are located within the head of the handle for marking measurements and measuring plumb & level, respectively.
When laying out joinery, it is often useful to strike a line parallel to the edge of the piece you are working on, using a dedicated marking gauge. You can achieve this by setting the square to the desired offset and running the square down the side of the piece with one hand while striking the line with the scriber or a marking knife pressed up against the rule. This process is also a great way to quickly and accurately transfer measurements to multiple workpieces.
Most combination squares have a removable pointed pin called a scribe that can be used to mark measurements on the object being squared.
By setting the blade at the desired depth, you can use the combo square to test the accuracy of the cheeks and shoulders of your tenons.
