Yesterday I installed a screw-down for my hatch. I used the same technique that I used for the drain plugs on this boat and on my T37, so I'll give the short version here and you can figure it all out.
Started by drilling an oversized hole in the forward end of the hatch and then through the king plank. It was just a drill bit size larger or so, enough that the screw easily slips into the hole and can wiggle around just slightly. You need room for the thickened epoxy.
I then rubbed in very well some wax onto a 10-24 screw and then put a very small amount of tape around the top of the screw.
Mixed up a small amount of epoxy and lightly clear coated the inside of the hole on the hatch and into the hole in the king plank. I used just enough in the king plank that it would soak in a bit but no more.
Then I added thickener to the rest of the epoxy until it was very thick. As best I could I forced a bit into the hole and then I gooped it on the screw, and then gently twisted the screw into the hole just until the top was near the king plank but not bottomed out. I twisted it a bit to try to evenly distribute the epoxy. Then I left it alone until this morning.
This morning I was able to easily "snap" it loose and it came right out leaving nicely formed threads in the epoxy.
I then also trimmed the forward brass tube that sticks through the hatch flush with the hatch. I won't cut the fin threaded rods until the very end so that I know exactly where to cut them.
Not the best weather today so I really can't start painting yet.
Peace! _/)
