The top/cap of my compression post show signs of needing replacement. It is pie shaped and is slightly wider at the top. There is a metal washer about the same diameter as the bottom of the cap that appears to be through bolted to the mast mount on top of the deck. I am guessing that that washer spreads the compression load over the cap and supports the mast mount on the cabin top. The only through points are the small pipe lead the cabin top and the mast mount bolts.

There are several open cracks on the edge of the cap and the washer appears to have crushed into the bottom of the cap. I believe that the situation has gotten slightly worse over the past year.

Has anyone removed and rebuilt this cap? Has anyone made a mold to fabricate it? Is it possible to have this turned from wood and then glassed?

Suggestions anyone?
