Typhoon Mast Sinking

[Tom]

Typhoon owners -

What is the vertical distance between the cabin floor and the base of the mast inside the typhoon cabin?

I am installing a compression post under my mast to relieve significant cabin sag. It is difficult for me to tell exactly how far I need to jack up my cabin due to delamination in the outside decking (visual lines are wavy).

I have found that a floor jack from the local home improvement store will work ideally for this project (less than $30).

I have to install a compression post as well. I am exploring the options at this time. Could you please post the make and model of the floor jack that you found? - Thanks - BVV.

I have pix of the compression post installation in my Ty at the link below. It's original equipment, I believe. I'll measure the height this weekend and post for you.

Floor jacks are traditionally used by home buildiers in basements and crawl spaces to firm-up sagging floors. I don't know the exact make and model, but I went to a home builders supply company (local outfit) and had an 8-foot floor jack cut down to size for me. After I went to that additional expense, I was walking through Home Depot and saw that they had a floor jack for sale exactly like I had made (for the 30.00 price I mentioned). I saw a variety of jacks for 2, 3, 5, and 8 foot lengths with 6 inches of extension. If you can't find exactly the correct length, a welding shop could cut it down for you. The jacks are typically located next to the cement and Quikcrete products. I would recommend that you go to the store to look for them or ask a knowledgeable assistant. I had called prior to having one made and they had absolutely no idea what I was talking about. If you have any other questions or need pictures send me an email or post a message.

PS After I had raised the cabin roof to where I thought it should be, I cut a section of gas pipe to length and inserted it as the compression post. Then removed the jack. I didn't leave the jack in place permanetly as it was big and ungly, but I am sure it would be adequate for longterm use. If my cabin is too high or low, as this board will tell me, I will simply reinsert the jack and cut a new post.

You might want to check the archives. There are some notes on compression posts that don't block the porta-potty alcove. Also some designs that allow future adjustment if necessary without removing and trimming length.

Tom,

The distance from the cabin floor to the ceiling measures 38.5". If you look on Joels' link, I measured from the floor to the aft part of the inset where he has a wooden backing plate.
Cheers,
Robert

Remeber that the idea is to transfer the weight from the deck to the keel, not just the floor of the cabin. The way my compression post was installed, it went through the cabinb sole directly to the keel. I don't know how you would do that as an owner-installed device, though. The picture of it at the site I've posted was taken by holding the camera in an area that I can't see unaided.

Good luck.
