This maybe is a slightly different than standard woodworking, but involves wood and glue, so I figured it's worth asking here.
I recently installed 4x4 treated wood posts using the Oz-Post method. This is where galvanzied steel fence post bases are driven into the ground and then the post is set into the steel base.
I used a bunch (8 per post) of wood screws to secure the fence post to the oz-post steel base. Then, for further strength, I squired Loctite Polyurethane construction adhesive into the space between the wood post and the Oz-post. (The Ozpost contains a special hole for this purpose, I was able to squirt to generally fill the area beween the oz-post and the wood post with adhesive. Maybe about 15 square inches per side or 60 square inches per post.) The gap ranged from tight to up to maybe 1/8". Perhaps up to 3/16" in a couple locations.
The treated wood post was quite green, as they usually are. It will shrink a bit when it dries. I'm curious what will happen when the wood shrinks? Will the Loctite Polyurethane Construction Adhesive expand? Will the screws loosen up over time and require retightening? Will something else happen altogether?
Thanks!
