fixing the compression post

hi. i have a 1971 cal 27 pop top. working on refitting it. my present project involves the compression post. the post below the galley counter has begun to rot and squish in the 2 3/4 inches between the floor and the bottom or the galley fiberglass. this has allowed the post to sink 5/8 on an inch. you can see it by looking at the top of the companionway to the forward cabin. i have some Brazilian walnut. it's supposed to last better than 50 years even buried under the dirt. i am planning on cutting the bottom 2 3/4 inches off of the existing compression post and making a mast step out of the Brazilian walnut. all the rest of the compression post is in fine condition. i think this will be a good solution to the problem. my question has to do with jacking up the roof/mast/compression post. i have never done this before. since the cabin sole is attached to the fiberglass of the galley, i was planning on removing the sole to allow me access to the floor beneath. i was going to make a temporary compression post, like you would when jacking up a house porch roof to replace the porch beneath, and bolt a bottle jack to the top. you can't get directly beneath the mast, so, i was going to set up my jack directly beside the existing compression post. since the compression post, galley, and bulkhead are all bonded together as a unit, i am hoping that jacking up the roof at this point will raise the whole thing up the required 2 3/4 inches. any thoughts, warnings, or advice you guys can give would be great. thanks.

first question: what caused the rot and has its source been fixed?reggie To: Ca… [at] yahoogroups.com From: Ca… [at] yahoogroups.com Date: Sun, 12 Jun 2016 09:37:07 -0700 Subject: [Cal_Boats] fixing the compression post hi. i have a 1971 cal 27 pop top. working on refitting it. my present project involves the compression post. the post below the galley counter has begun to rot and squish in the 2 3/4 inches between the floor and the bottom or the galley fiberglass. this has allowed the post to sink 5/8 on an inch. you can see it by looking at the top of the companionway to the forward cabin. i have some Brazilian walnut. it's supposed to last better than 50 years even buried under the dirt. i am planning on cutting the bottom 2 3/4 inches off of the existing compression post and making a mast step out of the Brazilian walnut. all the rest of the compression post is in fine condition. i think this will be a good solution to the problem. my question has to do with jacking up the roof/mast/compression post. i have never done this before. since the cabin sole is attached to the fiberglass of the galley, i was planning on removing the sole to allow me access to the floor beneath. i was going to make a temporary compression post, like you would when jacking up a house porch roof to replace the porch beneath, and bolt a bottle jack to the top. you can't get directly beneath the mast, so, i was going to set up my jack directly beside the existing compression post. since the compression post, galley, and bulkhead are all bonded together as a unit, i am hoping that jacking up the roof at this point will raise the whole thing up the required 2 3/4 inches. any thoughts, warnings, or advice you guys can give would be great. thanks.
