Dagger board removal and sandblast prep

Today, the weatherman says we’ll have a heat wave so we decided to get to work on the boat early and stop before we start to bake around 11 and to go back late in the afternoon, when the worst of the heat is over.  We’ll do “office work” in between.

We took an appointment with Chantal, the owner of the yard, to raise the boat and re-block it on the 22nd, because it’s so heavy it sinks into the loose gravel.  We’ll grab the occasion to get the dagger board out from under the boat, to prepare it to get sand blasted.  Since we don’t have the original drawings of the boat, that date’s a Damocles sword over our head:  we have no idea how the board is setup in there and nor do we know how to disassemble it.  So this morning after tea we got ourselves to the boat to scratch our… heads.  Our doubts are mostly centered on the pivot axis of the board.  Do we need to take it out after they lift the boat or should we get it out now, maybe just loosen it?  That board is a dagger, not a keel so it doesn’t have any ballast in it but still, at 7 foot long, it weighs in at around 400lbs;  Better be careful so it doesn’t fall on its side when they raise the boat.
  

Well it was once again much simpler than anticipated.  First we took weight off the axis by using a car jack under the board,  (more specifically Lucie’s Hyundai Accent car jack.  Don’t worry Lucie, it’s rated at 3000lbs).  Then after unscrewing entirely what I thought might be the axis but was in fact the board brake, we finally realized that the big cylinder which we had access to from both sides was actually the axis.  Moreover, it came out almost by itself with the gentlest of hammer hits.  That is one pin:  It’s got to have 4 inches in diameter and weight 20lbs.
The board is now free to drop under the boat.
