| Ruby Tuesday, since the bulkheads with the same biax do not show print through then the resin shrinkage is not the issue. If it was me I would be sending trough the gelcoated panel down to the biaxial to see what is different about it. And to make sure there are no nasty surprises hiding under the gelcoat and CSM. Cheers Andrew  |

| Marine survey, was there any spray glue used to hold the laminate together? It looks like your gel-coat or skin coat was contaminated before the dry-stack went on. Possibly was someone using PVA nearby? Also, what was the vacuum at when you shot the part? If you shut down your pump, could you see the vacuum drop? What resin did you use? Was it an infusion resin? Or did someone dump styrene in standard resin to thin it out? Were there holes drilled in the core to let the resin pass from one side to the other? How long was the resin flowing? -jim lee |
