Permanent Marker or Engineers Blue

For years I have used engineers blue as the basis for when I’m marking out a piece of work, but of late I have swapped to using a permanent marker.

Here I marked the table with a permanent marker and left it to dry before carefully marking the 8 radius lines.

I then used these lines to align the table on the milling table and then used a slot drill along each radius line.

The permanent marker comes off over time or instantly with a cleaning fluid.

Sometimes it is necessary to allow the permanent marker to dry and then apply another coat of marker, this then gives a much thicker application of black colour to mark onto.

The downside of the permanent marker is that it is more readily removed than the engineers blue. The benefit is that you get to a touch dry much quicker and you don’t tend to end up with it all over the work surface and your hands.
