I have been building my mast out of Australian hoop pine and was near the end of shaping it when to my horror i found that many of the bonds had not glued together properly.The biggest area of bond failure was along the sections of timber that had a slightly blue coloured streak in them.Little did i know but this is a sign that the timber has not been kiln dried properly.Also i had scarfed 8' sections of timber together to make up the mast and was not entirely happy with this,but as i had got the timber at a reasonable price i thought i was in front,anyway to cut a long story short i have placed an order for more timber at longer lengths through a timber yard whose owner was a boat builder in a previous life and assure me he will look after me.i figure that to have doubts about the stick out in the briny is not a game i want to play and shall do it all over again.
lesson learned.
cheers paul.

A man after my own heart! ;~) There's a Japanese proverb I learned from practicing Aikido: "Even monkeys fall out of trees." And, they get right back up in them! This will be the mast you wanted to build, Paul. . .

I have a moisture meter and when you're boat building in Ireland it's the best friend you'll have, well worth testing the wood before you glue up, I think you can pick them up on e-bay for as little as $20.
All resins differ but usually the moisture content has to be below 13%.
Get air dried rather than kiln dried wood if you can as the latter has a lot less flexibility.
