Layout Dye

Also called “engineer’s blue,” layout dye is used to make layout marks visible. The dye dries quickly, and marks from calipers or scribers can be seen clearly. Layout dye can generally be removed with alcohol, acetone. Removing layout dye from knurls and similar details can be problematic, so only use the dye where it is necessary.

Squares

Squares are used for laying out

Machinists Square

Combination Square

Protractor Head

Center Head

Center heads are used on combination squares to find the center of round workpieces.

Cylinder Square

Calipers

Calipers are used for both measuring applications (see Calipers) and for layout purposes. Most slide calipers are made with hardened points so they can be used to scratch layout lines.
