J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Too Many Holes

The weather was great today so after lunch I got everything sorted out and staged. One other bit of prep work was getting a seal on the inside of the cabin and supporting the old thin layer of glass so it is at least sort of flat. Then started by laying in 10 oz. cloth on top of the inner skin. Followed by a thick layer of CS epoxy resin and assembling the puzzle pieces of new core. Topped that all off with a little bit a peel ply and breather cloth (I didn't want the breather to get bonded to the core when the CS extruded around) and then sealer plastic. Used the sink drain as a vacuum port and turned on the Infamous Bad Mistake that has gone so right the Glast R1 vacuum pump. The beauty of this pump is its ability to work in a far less than perfect vacuum and run day and night until the epoxy fully cures. Using blue painters tape to seal the work saves time and a ton of expense too. This pump pulls an even 25" of H2o (not Hg) over the surface and IMHO is perfect for core work.

Tomorrow looks to be another good day so I plan to fill this top surface and get some glass on. After looking closer at the starboard side I think I can just cut the sections out for the high density core and leave the rest of the balsa core in place making for a smaller repair. I will still sand and cover these sections with new glass layers. On the port side I counted 32 holes through the cabin top in this one section.
