Re: Cutting laminate counter...in place
1 - If the counter is not glued down, remove it, cut it from the back, reinstall. Done!
2 - If the counter is glued, then use a jig saw with a downward cutting blade. A sawzall will work too, but it will produce a more jagged cut because the teeth cut on the upwards stroke, which will chip the surface of the laminate, among other things.
3 - Make your cut wide of your finished line, then come back and dress it up with a flush cut router bit and a straight edge.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
