trimming prefinished end panels
We are refacing our cabinets and I have a question regarding cutting the end panels. We are applying prefinished 1/4 " end panels to the cabinets and need to cut the large one, which goes on the back of the penninsula. We have to trim it in height, taking off about 12" and it will be cut across the grain. Do you have any tips for cutting so it won't splinter? I was thinking of putting some painters tape along the cutting line, and cutting from the back side. Any other tips? These panels are expensive, so we don't want to screw it up. All the other panels are cut to fit from the manufacturer, but they don't precut the cross grain, I assume because it tends to splinter. So any suggestions would be much appreciated..
