4x4<br />
Pressure-Treobd<br />
Post<br />
Typically, 4x4 pressure-treated posts<br />
are used to hold up a porch roof.<br />
They're strong enough for the job,<br />
COLUMNS<br />
but they just look skinny. One way<br />
to achieve a more proportional look<br />
is to wrap the posts with 3/+"-thick<br />
cedar boards.That is, to clarl the posts.<br />
To clad the posts on this porch, I<br />
used a three-step process that involves<br />
cladding the lower posts, adding a<br />
decorative nrid-cap, and installing the<br />
upper cladding (see lllustration at lert).<br />
Locking Rabbet - Joints The<br />
cladding is assembled with locking<br />
rabbet joints.This is a strong, durable<br />
joint that, when glued with exterior<br />
glue, stands up to the worst weather.<br />
(The technique for making locking<br />
rabbetjoints is explained on page 47.)<br />
Siod wlflr lower Cladding<br />
Essentially, the cladding is a "box"<br />
thatt built around the post. For easy<br />
assenrbly, it'.s built in two L-shaped<br />
sections that fit around the post.<br />
The size of this box is important.<br />
You don't want it to fit too tightly<br />
around the post. If the post nvists, the<br />
joints - strong as they are - could<br />
"blow" apart.The solution is to build<br />
in a "fudge factor" - that is, a gap<br />
between the box and the post to<br />
accommodate posible post movement.<br />
Most of the cladding work is done<br />
in the shop. Using the dimensions<br />
