[Rhodes22-list] deck shape

[Graham Stewart]

BoB:

 Thanks for the feedback. That is very helpful.
Yes, I had unstepped the mast and there was no load on the deck - not even
snow. I made the new bulkhead pieces using the old ones as templates and
placed them according to the fibreglass stubs that were in place to hold the
old pieces. Everything seems to be coming together properly so I am pretty
sure that the compression post base is in the correct place. The only
difference is that the old base had been distorting under the force of the
compression post over the years so the new piece corrected for that
accounting for perhaps as much as 1/2 inch in the drop of the cabin top.
What did you use to raise the cabin top in order to reinsert the compression
post? How much force did it take?
Thanks again,

Graham:  i assume that your mast has remained unstepped during your
restoration. 
Remember you have an inner hull so your cabin top has two layers. The center
of my cabin top interior dropped an inch immediately upon removing my
compression post.  I had the floor bulkhead replaced within a week but had
to lift the inner lining up to get the compression post to fit back into
place.  It is nice and tight and the deck is level and firm.  Fiberglass is
very flexible and strong. Make sure your base for the post is at the proper
height however.  Do you have an original bulkehad as well?  That helps you
guage that the compression post is in the right position.
Good luck!
