Hi M-list, I am trying to figure out a design for a compression post for my M-23. I have a stainless steel plate being fabricated by emachineshop that will transfer the load from the tabernacle and solid core deck to the three boards that are on the end of my bulkhead in the M-23. I am going to open the floor liner and set the boards on solid hull/keel with a glassed in block of oak at the base. I have some questions. 1.) What is the load from the mast that I need to make sure the compression post will carry? 2.) How to calculate the tensile strength (compression load) limit of the three boards (they will be epoxied together and form a U shape). I am assuming cross sectional area. And I will put in the factor for laminated boards. Any help would be appreciated! Thanks Robbin
