Lectroetch Grid Marking Stencils are available in size up to 10 in. x 20in. processed with a variety of squares or circular patterns. Please see PDF listing of patterns in automotive / die tryout section of this website.
A wick pad is dampened with electrolyte and placed on the stencil. The marker is rolled or rocked back and forth over the pad and stencil. A clear, sharp, permanent mark is produced in seconds.
The blank is cleaned, lubricated, and formed, after which the distortions of the circles are measured and proper interpretations made. Large areas can be gridded by moving the stencil in steps across the blank.
