Excessive
snipe
(gouge in the end
of the board that is
uneven with the rest
of the cut).
Note:
A small
amount of snipe is
inevitable if you set
the cutterhead below
0 on the cutterhead
height scale. The key
is minimizing it as
much as possible.
1. Cutterhead set even with or below sanding
drum.
1. Raise cutterhead to 0mm mark on cutterhead height
scale so sanding drum and pressure rollers are
below cutterhead.
Raised lines, ridges
or high spots on the
workpiece.
1. Nicked or chipped carbide inserts.
2. Carbide inserts not installed evenly.
1. Rotate or replace the affected carbide insert(s).
2. Make sure carbide inserts do not have debris under
them; make sure inserts are torqued down evenly
(
