Cutting through a surfboard
My house is set relatively far from the road and I'd like a large address display. I was looking to punch out the numbers [5 digits] down the center of an old surfboard, but not sure about what tools to use to get through the resin and then the foam; without shredding or splintering it. I have variable band, scroll, recip and jig saws; and a variable speed Dremel. I'd like for it to be as detailed as possible [hard edges]. I'm of course planning to illuminate it. Any suggestions, recommendations, ideas would be appreciated. Thanks in advance.
