In this example, we need to trim
the impeller to 5.00”.
Place the trimming sleeve over the
impeller to protect it from dam-
age.
Set the trim 1/4” less then the cur-
rent diameter. If you are not expe-
rienced with the material, then we
recommend only cutting 1/8” at a
time.
Trim the first layer at a slow
speed.
Use the X-acto knife to clean off
the loose plastic on the impeller in
order to get an accurate measure-

Check the diameter again with the
caliper.
