Mark 1 cabin refit ...

Post by luigisante »

After the epoxy on the back rail was cured, I scarfed a piece of teak onto the front rail.

After that, I glued the front rail in-place.

And finally, added a 48" shim to make sure the piano hinge on the upper bunk will have a proper point to rotate. Everything is screwed together as well as being epoxied or glued.

Now that I have the anchor for the bunk, I'm ready to start assembling the bunks themselves.

Started on the lower bunk. Here is the frame being fitted.

I elected to turn the frame on its side in spite of the loss of strength in this orientation. The bunk is the perfect height with the 1" width and is too high with the 2" height. Here is the underside frame cut to size.

The bolts on the port side bracket would interfere with the placement I wanted on the bottom bunk so I had to make room in the bottom frame. It's not pretty but it works.

BTW, here is the scarfed joint installed. It just needs a bit of filler and some sanding.

The bottom bunk falls 2" in its 6' length in relation to the shelf rail. The problem is that the seat back is going to take on the level of the rail, which it is going to be attached to. I can make up about an 1" in play by keeping the seat back just above the lower bunk. With a 1" shim on the right side of the bunk, it looks a lot better. I am considering incorporating this shim into a base for the bottom bunk (a kind of subframe).

When shimmed, you can see that it is close to the line of the shelf and the seatback won't look odd.

I am wandering out to the boat earlier and earlier after work each day. With the solstace upon me, I am feeling the need to move faster.

With the bottom basically finished, I need to figure the height of the rail on the base and position the back so that it can be hinged and pivot. Here is the base in place with the back close to its marks.

Here is a bress piano hinge dry fitted. No question that the measurements are correct and the hinge fits. The piano hing just doesn't look strong enough for me. I am re-thinking this and considering three larger stainless hinges.

The bunks are built and ready for final fitting. The rails on the bunks are recycled teak from the original outside rail along the amas.

Here is the top with the rails and subframe attached (smaller teak used for the top rail).

Here is some idea of the size. I fit so I guess my kids will fit fine.

And here is the top and bottom fitted in-place so that the bottom can accommodate a 3" foam cushion. Next step is a final fitting and hinging the top bunk.
