I have a great mast step made of micarta by a PO. It is approximately 8" in diameter. I am hoping that I am able to cut a 5 in. circle and clean out underneath. If I have to go further, I will, but then will have to be neater in the replacement area. Because of the mast step, I will have to match the curve in deck so I get a good seating.

So the plan is to cut as carefully as I can, clean it out and then stuff it with filled resin......Sounds like I am doing a turkey, doesn't it. How much time to allow for the epoxy cure is a mystery but with some contemplation, I'm sure it will come to me. The other task is insure that the cabin ceiling returns to it's original contours. Easy beans ...ja'think.
