Below is how I removed and rebuilt the compression post on Satori, the most comical part of this project was cutting expensive and important parts of the boat apart with a sawsall…
I looked at the compression post, wondering how I was going to grind out and remove something that was almost exactly the height of the cabin top. I figured if I cut the post in the middle I could easily remove the top half and have some leverage on the bottom half when I’m grinding out the epoxy encapsulated plate holding the post to the keel.
Next, I cut the post off with a grinder about 1/2″ down from the plate. I will be reusing the plate as it is already polished and matches the mast step bolts perfectly.
I choose 3.5″OD schedule 40 Stainless steel pipe. 96″ of it was about $300 shipped. Its pretty heavy duty stuff and weights about 40 pounds. The old post weighted about 20. In order to cut it we used a metal band saw and some cutting oil. Since the post is so long I needed a way to support it and accurately square it to the blade. A roll around car jack worked extremely well and the cut came out beautifully.
I ordered a new 7X7″ 14″ plate for the bottom of the post. Apparently, 1/4″ stainless is a pain to drill. I took it over to my Dads shop and used his Bridge Port mill to drill 4, 3/8″ holes that will be lagged into a 1 1/2″ GRP plate that I’ll use as a shim once I place the completed post back in the cabin.
