Seems that my daggerboard is getting progressivelly harder to raise. I know i'm just getting older but this is an ongoing thing.
I milled .020 off each side of the shims this winter, and now they are tight again. I wonder if, when you tighten down the rig, the trunk may close down.
Anyone notice this issue?

Larry, I think that the top of the board is actually swelling. Ours has cracks in the head that run fore and aft, among other serious issues. The board was NOT the most wisely engineered piece of the 7.9. Much of the original glass skin has delaminated too. When I get through with it, it will be better than new!
The quickest way that I can think of to hold the top together [semi] permanently would be to remove it, lay it on it's side, and then using a 3/8" bit, drill all of the way through the board to the other side, using the screw holes for the bearing strips. Don't worry if they don't match from side to side. Then blow the hole thing out with air and tape up the bottom side and the head. precut a couple of strips of wood to use to clamp the head together with and wrap them in waxed paper to keep them from sticking. Mix up some epoxy with just enough cabosil or high density filler to add strength, and fill the holes. I would use slow or mix some slow and fast hardener [depending on temp] to give the epoxy plenty of time to fill any cracks and voids in the head. Refill if necessary and then clamp. When it's all set, just redrill the screw holes into the new epoxy plugs and reinstall the bearing strips.

Dave, Thanks for the reply.
I had an issue with the board, several years ago. Completely cracked throught, right above where the weight is, so I know what bad design it is.
Changed out the winch, to an old one that I had laying around, this afternoon. Seems to work better.
Stay tuned as I get into this deeper, so to speak.

Larry,
We work hard to keep the board in good shape. i.e. if a crack starts to develop, remove board, dry, grind out crack and re-fibreglass. We also keep the board up and pinned when we are not sailing. Keeps it drier and cleaner.
You might want to measure the width of the top of the board to monitor any swelling.

Hi Bob
We do a lot of the same things you do, to keep the board in good shape.
I have the winch all torn apart on the patio table. After cleaning good I discovered a buildup, on the gears that looks like varnish. Will take the whole thing into work give it a good cleaning.
Stay tuned to - As the winch turns- I hope.
