- This one has been perking around in my thoughts for quite a while, as I
am feeling particularly maudlin this fine New Years morning I will try
and get it down coherently.
In early September last year I returned from a years National Guard
mobilization. I had stopped the emails from my various Yahoo groups when
I was mobilized. While going through demobilization at Ft McCoy
Wisconsin I was able to get on line and I thought --what the heck-- I
will reactivate my Yahoo accounts. I got emails started again from all
of them and then started to read back the last few days of messages on
the Bolger list. There you all were-- Peter L, the Bruce H's, David R
and Sue F with the plans still not finished for the I -60 , many other
familiar names, just like no time had passed at all. It was a tremendous
emotional impact, I was back in a part of the world I had been
completely separated from.
A friend caught me furtively wiping my eyes and asked me what was wrong.
The answer was "absolutely nothing is wrong, things are very right". I
was really coming home.
This group has always been a little different from other groups that I
belong to, lots of adjective's come to mind, helpful, humorous,
knowlegable, I have had a hard time pinning this one down. Mostly you
are just human the way we want humans to be, all the positive stuff none
of the negative. You are the people I would want as neighbors.
So have a happy Bolger new year, may your tools be sharp and your
plywood void less.

- What does Bolger recommend using for the foam? I gave some thought to
plywood/foam composite construction a few years ago when I tried building a
Brick with composite sides (I made some errors and finally threw my hands up
in disgust and scrapped it). For my use I figured insulation foam sheets
would work fine, but for something more ambitious I wondered if they had
enough strength. When stressed would the foam fail internally? Would
repeated stresses cause cumulative damage until you just had foam dust
between the sheets of plywood? Perhaps I was being overly pessimistic...

of materials for BWII, including the brand name of the foam.
If you Google you will find there are some very impressive home-
building insulation foams. Limited only by your pocket book. Some
have instructions on the net showing which adhesives to use and the
type of strapping. To me these foams will stand up to boat use and
are well in keeping with Bolger boxes.
- When choosing a foam you should also consider any
toxic fumes it might give off if it and your boat
happen to catch fire. Different foams have very
different levels of toxicity.

really got your hands full and your world is not made better with
the presence of less toxic elements either within the hull materials
and your boats contents :-0
However, some plastics do off-gas for many,many months and this may
be more delitrious to ones health in the long run......I think :-)

not seen Bolger address them specifically, but it strikes me as most
desirable to make the foam and plywood into a sandwich, with strong
adhesive. Structurally, this increases the strength for forces pulling from
the outside, that may occur when the boat is heeled. Also important, is to
prevent voids that can collect water. I was planning to use some 2-part
expanding foam in small left-over volumes around the foam sheets.
I have used the expanding foam before, and I remember problems in
controlling the stuff! It sometimes didn't want to go where you wanted,
and other times wanted to sneak out through cracks. I want to have all the
expanding foam in place before putting the inner plywood on. This allows
cleanup and redo of missed areas. The expanding foam I used also required
good ventilation! Maybe they have better products now, as this was 15
John K., I plan to do some small test panels with the foam sandwich. I can
drop off a sample for you to play with if you want? This will probably be
early Feb. You will probably think of good ways to torture the stuff.

David was working with! Thanks. I agree on the use of glass for the 1/4"
plywood, but it probably could be thinner than the bottom.

it for small sliding parts---but why not the boat. BTW, I plan to take the
boat all the way to the water on the trailer ;-)
I am really curious about the slot closure system. Can you elaborate
Bolger does not overburden us with details for the hard hatches. Made up in
four overlapping sections, they are again fabricated from a sandwich of
1-inch foam with 3mm plywood top and bottom. The aft section has a 32-inch
cover that hinges forward. They sit just high enough over the
standing-room comings to allow drainage between sections. There are no
suggestions for stowage. As drawn, they are too long to fit in the forward
These hatches are somewhat large, typically 2x4 feet. I will try to report
later on their apparent ability to bear weight. Again this is the sandwich
question. They also are easy to modify/replace, if needed.
My present plan is to build this type of hatch for the forward and aft
compartments and start out with a minimal soft cover for the middle (plus a
middle tent for camping). I'm still looking for proper latches.
Many thanks to all for the fine comments!

pushing/pulling the boat around in my shop and driveway during
construction. It makes sense to reinforce the 'points of contact'
of the hull, the center bottom of the fin keel, and the center
edges of the chines.

Hold up there hepcat. Mostly I'm a lurker here, but couldn't let that
one go. I'm substantially under 60, recently turned 39 (again), and I
certainly know Les Brown & his band of reknown. Of course, I played
trumpet for a few years. Right now I'm listening to a random selection
of: Glenn Miller; Miles Davis; Benny Goodman; Cab Calloway; Duke
Ellington. This kind of music keeps me hopping while I work on the
boat we're currently building.

Ah, yes, but... are you under 60 - as I suspect?
- Being partly Welsh, as my dad had it, means you HAVE to sing, doesn't
necessarily means that you're good at it <g>.
Hey, I'm not 60 (yet). My mom was a real bobbysockser, had tons of
Frank's records - and lots of Big Band stuff too. Some of us Baby
Boomers had lots of opportunities to listen to this stuff, just like
my kids had to hear all that sixties crap I played.
