Center Board SlotCleaning out the center board slot on the the keel side.
The slot for the center board needed some good cleaning.
The 1st part was to router out the slot with a finger router. The 2nd part with a convex rounding bit to smoothen down the edge.
With some tricky clamping a guiding board is set in the right position. I luckily got away without drilling holes into the keel.
