on a woodworking table its called a riving knife
can only imagine right way up the glazed edge is possibly finding a minute gap between fence and table
where as upside down it runs on the flat face
does the riving knife line up exactly with the blade ??
is there a minute gap between fence and table top at some or all points ??
it possibly needs adjusting
is there a blade guard attached
is there any gentle give if you try and move the metal sideways ??
RVP,
Great to hear.
However, it 'might' need that washer as my saw vibrates like mad.
If you can you might need to drop washer into hole and then put screw through it.
If you cannot, no worries, but check screw for tightness everynow and again.
