I have had several incidents where I ask for a sheet of 4x8 wood to be cut down into more manageable sizes at a big box store on a panel saw and the result was less than favorable. The resulting pieces were out of square and, of lesser issue, cut other than close to indicated sizes.
I have even marked the wood for them before, and am then left with the awkward situation of them still not doing it correctly.
Is there a trick to these panel saws that the employee's aren't aware of?
Has anyone had good luck with getting fairly accurate and square cuts at a big box store? What steps did you take?
