A
shim can be a highly effective item if it is used correctly. Of course,
how you use or insert a shim will depend on the application. For
instance,
using a shim to level and stabilise door frames and windows requires a
different installation method of using a shim to stabilise or
level furniture.
• Using a shim in window and door frames.
Once
you have the door frame or window installed and notice that there is a
gap, get the shims ready. Place a wooden shim into the space
between
the door casing/window and the framed area. Using a hammer, gently tap
on the shim until it pushes into place. You can use a spirit
level
to ensure that the window or door frame is level. If you find that 1
wooden wedge isn’t enough, you can insert another wedge by
tapping
it into the space right next to the first shim, except the other way
around (now the shims are top and tail). To ensure that the shim
stays
in place, use a set of securing screws. If there is a piece of wedge
sticking out, score and break it off using a utility knife.
• Using a shim to fix wobbly fence posts.
Sometimes
wedge posts and panels become loose and wobbly. The fence can begin to
lean or worse; make an annoying creaky sound. You
can
use a wooden wedge (or a few) to fix this. First, push the fence post
into the correct position and note where the loose space or gap is.
Now, take your shim/s and push it into the space. You may need to use a few shims and you may need to hammer or tap them in.
• Using a wooden wedge or shim to fix wobbly and uneven furniture.
If
you have furniture that stays in a fixed place, but wobbles when used,
you can fix it with a wooden wedge shim. First, wobble the table so
that
you can see which leg or foot has a gap between it and the floor. Then,
place a wooden wedge under that foot and test to see that the
table
is sturdy and level. Now, while the furniture is still standing on the
shim, use a pencil to trace the outline of the foot or leg onto the
shim.
You can have the shim cut into that
shape before you affix it permanently to the furniture leg or foot. You
can use double-sided tape or glue
to attach the shim to wooden furniture.
