The repair to my planking puck up is progressing. I am happy with the way this latest vacuum bag worked. The epoxy bleed out between the strips shows I am getting nice pressure and that the planks are making contact all of the way down the hull. The pressure needle on the pump is another good indication of a strong vacuum. So is the sound the pump makes: the pitch rises noticeably once the pump starts straining to remove air.
Four planks today. Four more tomorrow. The bag should stay on until the epoxy cures, so the pump will run all night. Final note: After my initial experience with a vacuum bag, I now use a stethoscope to check all of the way around for leaks. One of my shop mates asked me if I could give him a flu shot.
