I personaly feal that the incert but joint showen woulkd have a weak
spot at each end of the incert if inpacted as well as being more work
then a regular scarf joint. The second problem is they don't make
1/4" MDO for the incert. On my project I used regular butt blocks of
same ply thickness 1/2 but but went 8" wide. I instaled one sheet
then the butt block, alined the next sheet and attached at butt block
and worked down the sheet. When we had the rolling party no one could
find where they where till it was rolled they didn't show through.

Your "butt-scarf" looks like a good fix for a sheet that will be bent. If one is just looking for alignment on a flat panel, a biscuit joiner works very well.

Hi Chris,

and scroll about half way down the article to see one possible route
that may interest you regarding the joining of two 1/2" MDO panels.
It worked well for me :-)

If you are just trying to pull them up tight, why not
use a couple of rachetstraps to pull it tight and a
number of beveled blocks that have plastic under them
to push the ply down as you are pulling it onto place.
If you do it right the screw holes for the blocks will
be in the same place as the ones in the MDO of the
first sheet.
It's the same idea that is used to pull hull plates
into place.

Install a minimum of overhanging cleats on one side of the joint to align
the joint. Butter the panel edges with thickened epoxy, assemble, and screw
the second panel to the frame with just a few screws at first. Then pass a
rope loop around the work in the same direction as you would a clamp. Drive
a wedge under the rope, at one panel edge away from the joint, but not too
tightly. Then put in the rest of the frame screws. If possible, remove the
cleats and weight or force the butt joint against a flat surface, using poly
sheet to prevent sticking. Good luck.

After working with posttraumatic stress disorder patients for years,
Pennebaker had noticed a deficiency in people's self-reporting of their
experiences. So, he devised "a measure that would capture people's real
life," he says. His device, called EAR (for electronically activated
recorder) is a digital recorder that subjects can store in a sheath
similar to a case for glasses in their purses or pockets. The EAR
samples 30 seconds of ambient noise (including conversations) every 12.5
minutes; carriers cannot tamper with recordings.
Researchers used this device to collect data on the chatter patterns of
396 university students (210 women and 186 men) at colleges in Texas,
Arizona and Mexico. They estimated the total number of words that each
volunteer spoke daily, assuming they were awake 17 of 24 hours. In most
of the samples, the average number of words spoken by men and women were
about the same. Men showed a slightly wider variability in words
uttered, and boasted both the most economical speaker (roughly 500 words
daily) and the most verbose yapping at a whopping 47,000 words a day.
But in the end, the sexes came out just about even in the daily
averages: women at 16,215 words and men at 15,669. In terms of
statistical significance, Pennebaker says, "It's not even remotely close
to different."
