New to the forum and have a question. Recently had a pergola built and almost every one of the posts (8x8) are showing significant splits, some being worse than the others. I was told by the company the built it during construction (i first noticed some before it was completed) that all of the posts are center cut and not to worry. I'm more concerned now because a couple have gotten significantly worse since completion, and it's only been a couple of weeks. Should I be concerned? See pictures.
Posts should be free of heart centre material to avoid checking, and the ends could have been sealed, but those pictures wouldn't bother me. Wood checks. It can't be entirely stopped. Those checks aren't an issue.
Add a coat of stain next Spring.
Short of cutting off a body part, the worst that can happen in woodworking is manufacturing really nice looking kindling. --- Quoted from lenaitch
