OK, boat geek out time.
We were working on maintenance projects (as usual) today. Ann is polishing still. I decided to tackle the leaky chainplate. I’ve re-bedded this thing about 8 times since Mexico and it keeps leaking. I think I might have found a solution – but that’s not the neat trick.
I was unscrewing the screws that hold the chainplate covers down on the deck (four very small screws) and as I got to the last one the head twisted off. Oh, great! It’s about 1/16 wide and 1 inch long and broke flush with the deck. Nothing to grab onto with pliers. I tried to drill a hole in the end of it to insert a screw extractor, but it was too small and stainless steel is too hard. Usually the only solution is to start hacking away around the screw until there’s a big enough hole to grab it with vicegrips and twist out. The only problem with that solution is then you have to fill the huge hole that is left with epoxy and let it cure for a couple days and then redrill the hole, etc., delaying the whole project a couple days.
But…a mechanic friend once told me about a trick that I used successfully today. When you have a situation like this, you put a cutting wheel on your trusty Dremel tool and cut a groove on the top of the screw. Then using a standard head screwdriver you can back the screw out. It was a very awkward angle I was left with but – Yay – the trick worked.
Try it sometime when you have nothing to lose. It works!
