Select a concave or convex projection from the edge of the gauge to use as a guide for your marking.
Step 3 – Place gauge
Place the gauge against the work piece on which you want to leave a radius reference.
Step 4 – Select scribing tool
Choose a scriber or pencil depending on the permanency you wish to leave on the surface you are marking on.
Step 5 – Mark radius
Mark the work piece around the radius back and forth a number of times to make sure a clear marking is left for future reference. If creating a corner, make sure the gauge meets at ‘points of tangency’ (when both sides are met by the gauge).
Radius markings can be used as guidelines for cutting and should be followed precisely for fabricating purposes. When fabricating or fitting cosmetic panels, if measurements are not accurately followed the parts will not mount correctly.
Any miscalcualtion when mounting will result in paint or vinyl tolerances showing the errors.
