What happened?

[Bristol_Rob]

I was gluing up this little teak table and the top split.

I was clamping it and understand that I was applying pressure in a particular way. But when I look at the internal grain of the split, it looks odd.
Kind of like it's overly dry, and like it was suffering from some kind of rot or decay.

Has anyone seen something like this before?

The last photo is my attempt at repair

Looks like it may have had a pre existing shake in it unless thats the split. The holy bit could be a tunnel from a wood boring insect, i have seen similar. Also although Teak is regarded a highly durable it can & does rot if it is damp or in contact with the ground for long periods. Often in such cases the rot will be extremely patchy & localised.

I agree with your thoughts, it feels like there was a pre-existing flaw.
Notwithstanding that - it did glue back up nicely
