….. which resulted in a lousy vacuum bag. See the lots of tacky tape on the lower side of this vacuum bag.
Making wet vacuum bags in a flat position is not a big deal. But laminating on vertical surfaces or an oblique angle, the resin will drop down and contaminate the tacky tape. With resin contaminated tacky tape is useless and will make it extremely difficult to get an airtight vacuum bag. Therefore it is wise to close the lower side of the vacuum bag prior to the wet hand-lay-up. To remember myself (again) I made a serie of photos (see the gallery) that shows how it must be done in the right order.
Tomorrow I will start the mounting of the beam bulkheads. To be sure of the right position I will do a trial fit of both main hull halves.
