Yikes! I'm hoping we keep finding solid wood close enough to the surface to save it with epoxy filler before having to go this deep.

   Ten more frames, JUST TEN MORE FRAMES, ........TEN MORE!!!!!!!! and that will be enough. Here is special delivery for the frame that cradles the main mast step.  So there is the state of the boat, end of august 2012.

     WHAT?????? and miss all this fun? No, I am going to leave the chainplates as original. Have already rebuilt the portside chainplate blocks, and they are in place. You know, on a rebuild like this, where everything becomes totally accessible, they aren't that much trouble. But I certainly debated it in my mind and with friends.

           The new chainplate blocking is not a solid piece of dougfir, but a lamination of a very thick piece of white oak and 3/4 marine plywood, SATURATED with epoxy. In fact I will assume a leaky cap rail (although I don't expect it) and the whole area, frames and all, will be epoxy saturated.

One modification I am making is that the bulwark will not be plywood set on end grain. It will be a stack of high quality pressure treated southern pine - like I made the new outer clamps (sheer clamp) out of.  The stack(not vertical pieces)  will be fastened directly to the deck, as well as the two layers of 3/8 planking that extend above the deck. (I am doing two layers of 3/8" planking instead of one 3/4. Should be much stronger and more durable (the bulwark that is)).

It really has been great to hear from you guys. Think of YAWL often. Having Jasper's favorite, grilled okra, right out of the back yard, every other night!!!!!!!!  I posted an ALBUM on dampers with all kinds of good info and photos. I never could find a shouldered bolt the right length, so I torqued the grade 8's .to 30 ft lbs and let it go. hope I don't regret it. Also, REALLY glad you got a boat ride!!!!

          And finally, check out the cleaned up chainplate that is in the forground of this photo. A bronze ground screw, bronze bolts,  and stainless steel - an interesting combo!!!!!  The featured photo is after I wire brushed of all the corrosion obvious in this photo.This is the only chainplate that I found a problem with.  I have switched the bronze carriage bolts to stainless hexheads, and I may let the heads show, not sure yet. (Partly because I added a new 5/4 yellow pine layer, the full length of the boat, to the three layers of doug fir that form the inner clamps, so the bolts had to be longer anyway.)  (the inner clamp layers are the 6" boards behind the frames, obvious in this picture - not that you didn't know that - but you know Uncle Clyde's nomenclature is the universal language on this site!!!!!!!!  and I am glad of it.
