Not sure if this idea has been put up here before.
LOML when walking the dog comes across a number of L & P magnetic plates on walkways and road sides some brand new some not so.
I use these around in the workshop but of late have used it on the ML7 in front of the crosslide under the chuck and I have now cut one in 1/2 to use between the ways to reduce clean up time or steel swarf
I also use 2 or 3 at the drill press when drilling steel.
I have one which is slit and fits on the outward cut of the 6x4 metal bandsaw as well.
