I kinda covered how I jacked up the cabin top, mast, from my whole experience with this fix, you really need to de-mast the boat. To fix the counter top sag, you need to completely remove the metal compression post, the mast wires run through the post, making it near impossible to remove with the mast wires connected.Sailho, How did you jack up your mast. Did the loose turnbuckles give you any trouble with the mast not being stable?
Ah, I was the one who gave you the advice not Sailho, sorry Sailho, at least I think I was. I'm 510datsun, I posted up how I fixed the compression post with plenty of pictures, just didn't have the jack up pictures.Creager:1015759 said:Sailho, thanks for the info. You confrimed my thoughts on de masting because I didn't know how long the fix woud take. I appreciate the feedback.
I have finally gotten some time to post up pictures of when I jacked up the cabin top to do the repair on the compression post on my Islander 28.Sailho, How did you jack up your mast. Did the loose turnbuckles give you any trouble with the mast not being stable?
That's an option too. Not sure if they would work 100 percent using just one jack. The Jack needs to be placed off to the side of the area you need to cutout at the floor under the compression post. So, you will have an X and Y component on the jack.FWIW-
You can also rent a "lally column jack" cheaply at many hardware stores. That's the tall steel screw jack you often see holding up beams in basements. The advantage is that you don't have to worry about the end of a 2x4 slipping off the jack, since it is one very tall steel column.
I replaced the mast foot, all new wires and lights. I think I used a 1 1/2 diameter PVC pipe, drilled both ends the OD of the tube, and silicone it in. Once in place the PVC tube will be supported by the top and counter. I found it easier to have both ends the OD to make it easier to secure the tube to the post.510,
Well done! Thanks for the suggestion of the PVC sleeve inside the post. I am doing some work that will involve my mast step and the compression post. New wire routing for the mast, too. A sleeve makes good sense.
