His question is also related to using BS6566 instead of BS1088. I am not familiar with BS6566. I would do a boil test on a sample before using it on a transom (or anywhere on a boat). Boil the wood in water and see if the glue fails. You can glue the pieces together yourself, but if the glue inside each piece fails its still a major problem.
If the wood passes the test, I agree with Lee - you don't need a vacuum, just a lot of evenly distributed weight.

cape man he was only inquiring about using BS6566 it is the same as BS1088 only is allowed to have small voids. Not ideal for a transom. Can be used for frames. I think he is going with the BS1088 anyway.

Lee is absolutely correct. There is no need to get into the complications of vacuum bagging on such a large piece. Do as he did and you will be fine.

I wasn't thinking a proper setup. Just a house vacuum, a large vacuum storage bag cut open, some plastic and a roll of tape. Cost about $20. Just a thought. True most people laminate transoms without, just using screws or weights. I did, but in hindsight I'd try the vacuum storage bag.

Hi, I glued 3 layers (12 mm) without vacuum for my DE23. I always penetrated both glued sides and then applied the epoxy to both sides with a notched trowel. I used only 2 pins to match the edges.
First day I glued 2 layers a 2nd day add third layer.
