Used BookieB advice. Got things to fit better but had to cut a
radical angle on bottom stringer, probably 20 degrees. Still had to
reduce height of bow frame by 1/4". Managed to get sides mostly
glued. Am using epoxy that is very old and it seems to set up very
fast even with very little hardener.


With polyester you can vary the amont of catalyst to account for temp. or
time of cure required. With epoxy you should use exactly the amount of
hardener specified by the manufacurer. Mix only as much as you can use;
as you say it cures quickly... the exception being if you spread it out
thin when it can take a suprising amount of time. Therefore a little in a
large pot will set more slowly than a small pot full, if you see what I mean.

Use gloves and generally keep it off your skin; some people do react to it
over time. Many yards keep a bucket of water for dumping the used pots in...
well, it keeps them from smoking anyway!

Did some filling with epoxy and installed the upper transom gusset.
Am now ready to paint the interior tonight. Any thoughts on
reinforcing joints with fibreglas tape?

As for epoxy, I once ground out all the blisters, refilled them and
faired and epoxy coated and then painted a badly blistered 23' boat.
It was the most complicated thing I have ever done, more complicated
than any of the physics courses I took. Epoxy is nice to work with,
much better than the smelly regular fibreglas resin. My skin seems to
have no problem with epoxy. My epoxy resin is 10 yrs old and left
over from that project.

An interesting product would be fibreglas tape, say 4" wide in a bag
pre-impregnated with resin that would catalyze on exposure to water.
It could be used by home boat builders or by boaters in an emergency.

This afternoon, I managed to get the inside of boat #1 painted. It is
now ready for decking.
Yesterday, I did the centerboard box for #2.
