I did something like this years ago. I made the hole in the plywood
about 4 or 5 inches bigger all around than the stovepipe. I stapled wire
lathe to fill the gap and then applied cement (concrete) on both sides --
I used a very rich mixture. It held up for more than 5 years before I
sold the place and never had a problem.
