Compression beam being bolted thru the deck. Compression beam series of thru-deck bronze bolts. Center three go thru previously epoxy and Xmatt reconstruction directly under mast. Outer bolts pass thru composite balsa core with classic hockey-puck treatment - oversized holes and undercut skin. The original unglued support beam was locked in place with only two #16 bronze screws driven thru the circular mast-step into the beam under balsa-cored deck.
