Glueing frames, riser blocks, and daggerboard trunk

I glued on the daggerboard trunk with 3M 4200 today.  I applied a lot of the glue, then clamped it down with a couple of boards and a bar clamp, turned over, and screwed it in place.


There was a lot of squeeze-out, which is good, but what a lot of waste just to get a waterproof seal.  I would estimate that half of the glue was wasted, but I guess that is what it takes.  I'm pretty sure nothing will be coming up through that joint.


I know, it is a lot of fasteners.  More than needed, but it will be strong.  I will be routing out the rest of the slot with a flush-trim bit once the glue is set.


Looks pretty good all cleaned up.


I also have the riser blocks and half frames glued in at this point.  I decided to go ahead and use epoxy on all of these.  I will also use epoxy on the breasthook and quarter knees.  The gunwales, rails, outer stem and keel will all still be bedded in dolphinite and removable for repair.




I tried to get the trunk as true and straight as possible.  For a while I wore myself out by putting a small level across the trunk cap only to find later that the cap was not sanded true.  I eventually rigged up a device to check the angle coming out of the trunk slot.  It didn't come out perfect once glued up, but I tell myself that the dagger board will never sit perfectly upright in the slot anyway, it wedges to one side or the other when under way.  And, it will look fine, why worry?
