I bought a fake butcher block counter from Ikea which is really a veneer over particle board. No matter how I cut it, I can't seem avoid slight chips in the veneer. I'm using a 7 1/4" circular saw and a 60 tooth blade. I have someone holding the end of the cut piece, but I suspect because it's so heavy, its impossible to avoid flexing all together as the cut gets close to the end. I've tried with both the veneer facing up or down and even a piece of painters tape over but it doesn't seem to make much of a difference.
What are some tips to help prevent chipping of the veneer?
