A removable compression post

So this season I have been gearing up and changing my rigging around bit by bit as I find pieces here and there.  My ultimate goal is to  rig up a mast top spinnaker for use later in the season.  So far, I've got the mast head halyard set up.  Today I took the next step and installed a removable compression post.  My Typhoon has the saddle supports that came with older Cape Dorys but I thought it best to add a bit of extra support before trying out the mast head spinnaker.

So here is what you will need:  A nice piece of teak, two other (less nice) hardwood boards for underneath the floor cut to 4 1/2 inches,  epoxy, 3M permanent mounting tape and a master lock adjustable door jam.. I routered the teak to give it a soft edge for when I bang my head into it.  

Nice board ready to install.


Setting the Teak upper.
I drilled holes in the back of the teak plate to match the mast step through bolts.  I did not remove the mast step and put extended bolts on.  I wanted a smooth surface on the bottom of the teak no bolts coming through to hit my head on.  They would also be in the way of the compression post.

 Even though I had to offset one of the holes it fit like a glove holding itself up.  A nice tight fit.  =-)

Fits like a glove. 
This is where the 3M permanent mount tape comes in.  This stuff is tough but not completely impossible to remove should I need to remove the mast step at a later date.

Stick to ceiling. 
 Here it is installed. I'll varnish it later when I do my maintenance coat on the rest of the teak later in the season.
Upper installed.
 I started thinking I'd go in this way.  After fishing the blocks back out I ended up putting them in through hatch in the v berth.
Not the way to go.
After some wiggling and jiggling I pressed the boards into place.  Then poured epoxy in around the base.  I will probably do this a few more times to be sure it does not shift.

In place below cabin sole set firmly on the keel.
The next step is to find the right setting for your master lock door brace.  As you can see it is quite adjustable.

Here it is final installation.  The master lock bar is held in via tension between the cabin sole and the cabin ceiling.  The best part of this installation is the compression post can be removed and the V berth is fully functional.


Installed floor to ceiling.

 Finally, there is always the question where to stow the head?  Mine fits quite well under the cockpit sole.
