12. CORRECT PLANER BLADE SETTING (SEE
FIG. R)
Your planing surface will end up rough and
20
uneven, unless the blade is set properly and
securely.
The blade must be mounted so that the cutting
edge is absolutely level, that is, parallel to the
surface of the rear base. Fig. R shows some
examples of proper and improper settings.
R
(A) Front base (Moveable shoe)
(B) Rear base (Stationary shoe)
P
1) Correct setting
Although this side view cannot show it, the edges
of the blade run perfectly parallel to the rear base
surface.
2) Nicks in surface
Cause: one or both blades fails to have edge
parallel to rear base line.
3) Gouging at start
Cause: one or both blade edges fails to protrude
enough in relation to rear base line.
4) Gouging at end
Cause: one or both blade edges protrude too far
