> To Me the boil test is the stupidest thing I've ever heard.By and large,I agree with you. It is my recollection that the whole
point of the boil test is JUST to determine whether or not a piece of
plywood is"marine" ("marine" ply uses waterproof glues,cheap ply does
not)and not necessarily whether or not it is suitable for use in

To Me the boil test is the stupidest thing I've ever heard. Just for
grins I test a 4 inch square of a popular sailboat (Flicka) that had
been crushed in an accident. I put it in a pot of boiling water to
test it against the plywood boiling test. Now I know this boat had
made 1 circumnavigation of this beautiful planet. And I'm sure
everyone on this board has heard of the sea keeping abilities of a
Flicka. On to my test results. In as short as 12 minutes (could
have been shorter but I was on the phone) I had the ugliest soup you
can imagine. Anybody ever try the boil test on epoxy? I don't boat
in boiling water. Now a freeze test I can understand and have done.

The test I read about in 1981 when I built my first plywood boat was to boil
it for 20 minutes, then put it in the oven on low for 20, then boil it again
for 20 min. If it stayed laminated through that it is good for boat building.
I recently tested a piece of a 5 ply 1/4" from Menards that is sold for tile
underlayment. After only 10 minutes of boiling I had 5 pieces of wood. That's
bad.

In a 4 quart sause pan, and three quarts water and one four square inch piece of plywood.
Boil on high for one hour.
Pass - it still looks like a piece of plywood.
Fail - wood soup.
I prefer the dishwasher test myself.

I have seen mention of testing the suitability of plywood
for boat building by boiling it. Could someone describe
how this is done, and what would be considered "passing"
and "failing"?
