I'm just about done with that hole centerboard thing.

The metal working took a while.  I had to cut and shape flat bar to hook the raising/lowering rod to, then find a way to attach the rod.  Then I had to cut the pin and covers.  It all took a while.  I still need to make a handle for the end of the rod, but I'm not quite sure what I want to do, so I'm going to wait.

I decided to fill the circle in with some epoxy so it wouldn't slop and band around as much.

I cut some bar to length and then screwed it and epoxied it to the board.  After testing, I had to cut some of the ends as they were a little too long and would bang into the top of the case when dropping the board.

I over drilled the holes for the pin so I could fill it in with epoxy.  This will both seal the plywood edges as well as provide a bushing to reduce wear on the hole.

Then I cut some plates to cover the pin and seal it.  I need to get some rubber sheet or similar to use as a gasket.

 Final step was to fit it in place and cut the centerboard slot.  Tomorrow I'll epoxy it in.
