Re: [bolger] Re: Light Dory Evaluation
Rick,
A technique I have used to eliminate evidence of the external taping on a
bright finished boat is to glass the entire panel with 4 or 6 oz. glass on
the outside prior to assembly, along with taping the butt on the inside.
This eliminates the extra layer of glass tape and makes the transition more
subtle. Of course, it is only viable if you intend to glass the whole hull
anyway. It is also worth a little effort to choose plywood panels with
roughly the same color and grain for matching. I have found that dark panels
conceal the butt joint better than light panels. A dark stain applied to the
panels prior to epoxy and glassing might achieve this effect, as well, but I
haven't tried it. If you try this be careful not to stain the end grain at
the butt edges too much.
I applaud your effort. There doesn't seem to be any examples of a bright
finished light dory around, and the sweetness of the design's lines would be
augmented by such "gold plater" treatment,
Thanks,

I have tried various ways of fiberglass butts, including
Payson's. In my latest cartopper venture I used 6" wide 1/2"
thick melamine (spelling suspect) strips, a little over 4' long
as the outer parts of a sandwich. I set down a melamine strip,
put down wax paper over it, laid down a strip of fiberglass tape,
wetted that out with epoxy, carefully placed the two pieces of
plywood to be butted on the fiberglass, laid down another layer
of tape and wetted that out then came wax paper and another
melamine strip. I then used sheet rock screws to pull the whole
thing together. The melamine is very smooth, and the butt joints
came out likewise. If you gave a little thought to where you wee
going to cut on the panels, you could probably screw through in
between parts. I plan on filling and painting so I didn't care if
I had a screw hole in the middle of a panel.
Of course I didn't photograph any of this so verbal is going to
have to do.
