If you end up doing it again with the same material, I'd suggest using a
metal base instead of wood. I suspect the chisel is squishing the gasket
material down into the wood slightly, thus stretching it (the gasket) at
the edges. Use a metal support of some sort (vise? anvil? :-) that won't
give under the pressure of the chisel, make sure the chisel is sharp, and
you should get crisp, flat edges on the gasket.
