Re: [bolger] Admiral name?
HJ,
My curiosity was stirred up by this so I took a
look at:
Part of his strategy was highly trained,
lightweight, and nimble crews with simple weapons. So its easy to see why Bolger
thought the success of this admiral was significant - skillful use of
simplicity.
Thanks for brining this up.
May your day be filled with clarity, grace,
strength, insight, balance, cooperation, and warm laughter,
Roger

Chief,
I'm always curious about trees, do you know what
kind of cedar it is you are referring to here?
That is really interesting about pine and Titebond
II.
Here in the land of Douglas fir, in the Pacific
Northwest, we are seeing more and more pine. The nice Douglas fir wood came from
old growth that is mostly gone now, and it takes that species a really long time
to produce large trees with lots of clear heartwood. The pines in the south seem
to grow faster, and so I think the pine tree farms there produce more wood per
acre per year than the Douglas fir tree farms here do. So it seems likely we
will be seeing more pine here as time moves on.
When I grew up, pine was considered adequate for
cheap disposable uses of wood. However I'm fond of pine and much of my furniture
is made from pine. Part of the inside of the home I grew up in was paneled with
tongue and grove pine. So I'm inclined to use pine, where it will work
well.
These days a lot of the "fir" here is actually
hemlock, which I don't like as well as Douglass fir or pine.
So its good to know you think well of pine for
boats. I think I'd rather use high quality pine than trashy fir, especially if
it isn't really fir in the first place. Also pine is lighter than fir, which is
good for small boats you move around by hand.
We have a lot of really damp cold weather here. If
stuff in an unheated uninsulated shed gets really cold, and then a foggy drizzly
warm front comes through, a layer of condensation will form on the cold surfaces
inside the shed, and the tools tend to rust a bit from this.
You would think that tools in sheaths would trap
this moisture and rust worse than the exposed tools, but it doesn't work that
way. I don't use rubber sheaths, they are either leather, fabric, or
carpet and so are permeable to moisture and will dry out if the tool was
wet when it was put into the sheath. The sheathed tools in my shed don't rust
the way the exposed metal on other tools does.
So whether the moisture condensing out on the boats
is frozen or liquid, it seems like covering them with blankets would help
protect the wood from picking up moisture from condensation when they are
in storage.
May your day be filled with clarity, grace,
strength, insight, balance, cooperation, and warm laughter,
Roger

Chris,
Your description reminded me of the fourth
Cheech and Chong movie "Things Are Tough All Over" where they drive cross
county. The car gradually falls apart until there is nothing left of it and they
are left sitting in the middle of the road.
This skit wouldn't be so funny if this was a boat
and you were a long away offshore in bad weather.
Even cheap exterior plywood generally delaminates
slowly enough that you have enough warning to head back to shore. A risk of
quick massive delimitation sounds a bit scary, especially if its thin
plywood.
Recently I washed a pair of inexpensive running
shoes, and the glue dissolved while they were being washed, so now I have a pile
of shoe parts.
* * * *
I think we are on the downside of a peak in
manufacturing quality, and need to be very cautious about glue
quality.
Since manufacturing standards can quickly shift,
and different plants have different standards, when buying generic plywood it
seems reasonable to buy only one sheet of plywood, cut out a piece and do a boil
test on it. Then if it passes the boil test, quickly go back and buy more of
that plywood, as long as its from the same lot that the boil test was done
on.
If stock isn't from the same lot, then start over
with buying a single piece of plywood, do a boil test on part of it, and then if
it passes, try to buy more of the same lot.
* * * *
I suppose an advantage of buying MDO, with markings on it from a known
manufacturer, is that the main market for it is commercial firms creating
outdoor signs, and so if the plywood delaminated before it rotted,
then the manufacture would quickly loose their market share.
Buying generic commodity plywood is seeming lots riskier now than it used
to be.
May your day be filled with clarity, grace,
strength, insight, balance, cooperation, and warm laughter,

I've cut a lot of Cedar trees.. If it lays on the ground for very long
the soft parts rot away like a pine tree, pretty fast.. All that will
be left is the heart and it does not rot fast.. There is not much of
it but it makes good kindling like the pine heart. I would not build a
boat out of Cedar UNLESS..It were cedar strips cut out of a cedar
board. ALSO.. IF I used cedar strips ( once they were used to build
canoes ) I would make sure to cover it and keep water off the wood.
Years ago cedar canoes were covered in Canvas and paint... SO.. the
short answer is. NO..I simply would NOT use this stuff...I don't like
it any better than Luan..
Years ago I found some Luan that was decent and it did not check but
over the years Luan has gotten so sorry it's almost usless... I did
use some lately......Pine WILL check every time..No exceptions.....
Most woods WILL check if used on a boat. The small cracks open the
paint lets water seep under the paint into the wood and the wood
swells further cracking the paint and water can soak into the wood
causing rot..In winter the wet wood freezes and damages the boat even
more... To stop Checking I laminate my wood with a fabric and
paint.....
On a cheap boat I use Titebond II to stop checking. I now use pine ply
plywood for all my boats..So far this has worked well stopping
Checking on all wood including Luan....I apply TB2 to the new wood
then coat that with Exterior Latex house Paint so the two can cure as
one....
Apply TB2 with a brush and DO NOT miss one spot of new wood..Soak it
into cracks etc. It will heal and seal...IF you could find the voids
and fill them with this it will seal them as well. I have injected it
into voids by drilling a small hole and using a syringe and
needle...It takes a while to fill a void due to shrinkage..If you cut
a bigger hole you can pack it with wet saw dust and TB2. Eventually it
will fill and works well. I tape over that with FB..
For an expensive boat I would use Epoxy and fiberglass..
My next boat will be12 feet long. It will be heavier than a Luan boat
but it will be trailered. It will be built out of 1/4 Ext. Glue Pine
Plywood and 3/8. All wood will be sealed with TB2 and painted over
with Latex Paint..It will be stored dry out of the sun and it will
last a very long time. There is a benefit to a sort of heavy boat. It
will move through a tack better and it may sail better.. In water
weight is not as important ( up to a point ) was it is to a man
handling the boat on land..
The problem with 3 ply Ext Glue Pine plywood is Moisture causing
WRINKLES or big long strips of bubbles where the top coat buckles due
to a void beneath.. It looks ugly but if it's small and inside the
hull it's seldom a real problem. Some of them open will crack and open
and those I fix...The ones that do not open up I don't bother with if
they are small and inside the hull. When the boat is fabric coated on
the exterior I have never had the hull wrinkle. If not coated with
fabric and the wood does wrinkly you can fix the wrinkle easy. Cut it
out and glue in a strip or fill and epoxy and glass over.... .
After a while you will have found all the weak spots and repaired
them. In fact as my boats age they look better due to making repairs
and adding more paint..In fact they are better..
I wet sanded ( latex must be wet sanded ) and painted my old Skiff
this year. She looks new is solid and better than the day she was
born..I scarphed the mast making it longer and went from a Sprit sail
to a Leg Of mutton..
All my boats are dry stored.. In fact during winter I cover them with
blankets inside the shed so moisture don't form on them as Frost..
Frost can form on things rain and snow can't reach..
Taking care of a boat is the life of a boat.. Wooden boats can last
for a life time. I expect to die and leave some nice boats behind..
Old but nice..
If my grandsons take care of them these boats will be alive when they
die and none of them are made out of expensive wood. ONLY 1 has Marine
Grade Plywood. That MG ply checked like crazy until I put fabric on
it.. Good luck, Chief...

A critical issue is checking if the wood plies are
heartwood or sapwood. This could vary from sheet to sheet, so people's
experience with it could vary.
While the heartwood of the western red cedar is
more resistant to rot than the heartwood of Douglass fir, the sapwood of western
red cedar rots faster than the heartwood of Douglass fir.
Confusing this situation is that while the western
red cedar is in the cypress family, in the genus Thuja, and cedars are in
the pine family in the genus Cedrus.
It seems possible that the difference in rot
resistance between sapwood and heartwood is a common issue, and with the general
lowering of standards, that there could be more sapwood in plywood than there
used to be. As a general rule of thumb, the sapwood is lighter in color than the
heartwood.
It seems likely the sapwood of western red cedar is
so vulnerable to rot in part because it is so soft. While its hardwood of
western red cedar is also comparatively soft, it is also saturated with very
toxic chemicals (unlike the sapwood), and so is very resistant to rot. These
issues might affect other Thuja and Cedrus species.
May your day be filled with clarity, grace,
strength, insight, balance, cooperating, and warm laughter,
Roger
