[Rhodes22-list] Re design of Rhodes Interior and elimination of compression post.

[John Shulick]

Hi Rick,

 It is my understanding that putting a load in the center of the arch would
try to flatten the arch out which would transfer the load to the corners of
the bulkheads. those bulkheads were cut using the original wall which I
removed in one piece and am saving just in case. They fit flush to the cabin
interior. The starboard bulkhead is sitting directly on the original
stringer (see first pict) the port side is offset by 1/4" because the bench
seat rests on that side and is held by screws. any additional load is also
carried to the keel by the 1x2 hard wood boards that look like trim pieces.
To install the arch I had to first wedge it into one of the corners and then
use a piece of wood ( the original post worked quite well) and pre load the
cabin ceiling. Once you have the other end held up you CAREFULLY use a SMALL
hammer to slide the arch into place. The arch is held in place by that
tension and although there are no screws I can't budge it and I am a strong
person. I feel pretty confident that when the mast is up and the rigging
tightened the whole thing should tighten up even more. Note: IF the
bulkheads were extended all the way into the corners where the hull and deck
meet AND then glassed in you could then shorten the the spreaders on the
mast and the stays could be moved to the cabin top attaching through the
roof and directly to the bulkheads. That would allow a genoa track to be
installed in the corner where the deck and cabin wall meet allowing higher
pointing ability. The bulkheads would transfer the heeling forces and the
cabin roof would not carry the load. But I'm not ready to try that yet.
