[Public-List] What size fitting for new teak cap rail

[Mike Lehman]

Glen,

I pretty sure that I used #10 screws when I did this job many years ago. The 
wood was specifically chosen for its tight even grain. Even then, I broke a 
piece trying to bend it. The most severe bend is from the shrouds forward. I 
used 5200 to bed the rail. I also drilled out the pop rivets, opened the 
deck hull seam slightly and filled the seam with 5200. No leaks ever! What 
prompted all this work for me was a collision with another Alberg in a race 
in high wind when he lost control of his boat (spinnaker up in 35 knots) and 
t-boned me on the port side about 4 feet back from the bow. The collision 
opened the deck/hill seam from the point of collision all the way back to 
the jib track and the deck was lifted about 3". You could go below, climb 
over all of the cabinetry that was laying on the cabin sole and look out 
through the deck/hill seam.  We finished the race, but on a starboard tack 
the water would pour in so we would flip over to a port tack to pump the 
bilge. BTW, we were protested from the race because the race committee said 
that my #1 priority was to display the red protest flag...since it took 
about 10 minutes to determine if the still seaworthy, I didn't get the flag 
up in time and was disqualified.

These are strong boats!

Subject: [Public-List] What size fitting for new teak cap rail

hello all,

I am wondering what size screws to use to fasten a new teak cap rail onto 
the bulwarks I replaced my old toe rail with?

the new bulwarks are 3 3/4" high, 11/8" thick, and I have milled some 12' 
teak boards into 5/8 x 2" cap rails.  the problem is teak is not very bendy 
so doesn't accept the curvy lines of the Alberg 30 very well, particularly 
amidships, it twists and jumps  up and turns over pretty easily because of 
stress in the wood fibers,  and fractures and breaks if bent to much,,, so 
lots of stress along the grain of the wood.

I  steam bent the milled pieces to mitigate the curve of the hull pretty 
well, but am  concerned about what size wood screw to use to fasten the cap 
rail down onto the bulwarks.   I have done one segment of cap rail with #8 x 
11/4" wood screws, leaving about 7/8" embedded in the bulwrk and the top 
portion of the screw countersunk half way into the 5/8 cap. But the # 8 
screws seems a little puny!

if  I use a larger counter sunk  woodscrew, say a #10 would that weaken the 
cross section of wood across the cap rail to much at each screw,  (12 to 16" 
spacing along the rail) or if I stay with the smaller #8 screw, will that be 
to little holding power once the ocean slams into the already spring loaded 
teak rails??

I think I am inclined to go with a larger #10 screw, but would appreciate 
any advice (tomorrow I install the second length)

P.S.  Also, thoughts on screwing and glueing the teak more or less 
permanently to the bulwark with epoxy, or just bed it with dolphinite 
bedding compound... The bulwarks are sapelle, a form of African Mahogony, 
hence susceptible to rot at some point..

thanks much!
