The document I have is from O'day and is titled "Daysailer II centerboard problems and fixes".
The parts that relate to the board jamming are as follows:
Check for warping
check to see if the centerboard has expanded (in the lower 2/3's area). If so, the board can be ground down somewhat (use care-thin glass in this area). board may have to be replaced.
Check to see it the Centerboard trunk sides have bulged in (around c/b head area), (solid glass in this area-can be ground a good deal) If this is the case, measure the distance between the sides by trying to pass a 1" dowel back and fourth,cutting it down until it passes and then measure the dowel. Grind point of contact only. try not to grind edges because this could allow rope,and/or wire to pass between c/b and trunk, causing a jam.
excessive paint, and/or grease have been known to keep the board from lowering.
That being said, I put my board in today and it seems to raise and lower well with three coats of micron extra on the board and two in the trunk.
O'day makes it sound like they made the trunk to fit the board so if you have some swelling or a different board you could have problems. you should also check to see if you have cables jamming which could be a problem.
