Randy, I made hand rails that bolt to the teak hatch slide covers, using the existing holes. I decided to leave the bungs in until I got the cover off the boat and then knock them out by diving the bolt from the nut side. That part worked just fine. A harder task was getting the nuts off without access to the screw heads. Most of the nuts came right off because the screw heads were glued in place, probably from the bung glue. There were three nuts that just spun the bolts. For these I grabbed the bolt tip with vise grips and backed out the nuts as far as I could. I then cut off the bolt tip that I just destroyed with the vise grips, so it wouldn't bind the nut. Next I wedged a flat screwdriver under the washer behind the nut and pried as I backed out the nut. A lot of pressure can be put on the bolt this way and although the screw head may slip some, it will grab enough to get the nut off, by applying more leverage and synchronizing the pull on the screwdriver and the spin of the racket wrench. If you run into any really stubborn nuts you can always go to the drill and chisel method, but the way the bungs are on the curved part of the toe rail, I would be afraid of doing some serious damage to it with a chisel.

What's the chances of two boats starting out in the same place, traveling in different directions and ending up in the same driveway twenty years later.
