On our deck the balsa core is 3/4" thick, so a small chisel worked best to remove 1/4" of core around the hole. Just worked on a smaller panel where the core is only 1/4" thick. I put the pointy end of a 20 penny nail in a drill chuck, bent the headed end over to a 90 degree angle using visegrips and a hammer. I figured I wanted about 1/4" for gouging out the balsa, so cut the head off at that length. It worked great, and was very quick. I drill the oversized hole 3 X the fastener size, so I drilled the 3/4" hole, placed the nail into it and started the drill, and gouged out the balsa material, using the rim of fiberglass as a guide.

What you are doing is entirely the right approach. All holes through balsa or any other core should be "potted" with epoxy. Use the slow hardener though, the fast hardener generates a lot of exotherm on that much filled epoxy and may even boil.

I've heard that a bent nail inserted into an electric drill works. But I wonder if there is a tool designed specifically to do this job. Any advice would be greatly appreciated. Thanks. Pete W.
