[Rhodes22-list] Compression Post and Head Door Problems

[Allyn Baskerville]

Graham, you are correct. The floor support was not installed properly, which made the floor sag - the support was at least 1/4” too low under the front of the floor and 1” toward the back. Hence, no support directly under the compression post. 

I made the unfortunate mistake of attempting to remove the piece of wood (OSB) that was installed improperly. The board just crumbled into pieces.  I should have screwed some other pieces on either side of the OSB to support the floor. I have a plan to fix, but it’s more work than just attacking to what was already in place. All wood that is going in is pressure treated and epoxy coated.

If possible use pressure-treated or epoxy-coated wood to fill the gap between the solid cement base to the bottom of the floor boards - which might need to be replaced to make them flat and at the correct height. You can check to see whether doing so makes the post fit. It is also possible that some previous owner removed the post with the mast up and had to shorten it to get it back in place. That would be a really dumb thing to do but not something so dumb I might have done it. If the post is still short you might shim it to be snug or replace it altogether.
