Go ahead and cut the sheeting, it's accurate enough. leave a good bit of overhang, and then when you get the cores, just trim it to about 1/8" around overhang.

Mike,
Sorry to be dense, but I can't decipher your answer

Are you saying that the dimensions given on the sheeting templates include adequate overhang, or I should add additional overhang to the dimensions shown?
Thanks,
