PLANING WARPED PIECES
If the wood to be planed is dished or warped, take light cuts until the surface is flat. Avoid forcing such material down
against the table; excessive pressure will spring it while passing the knives, and it will spring back and remain curved
after the cut is completed.
PLANING SHORT
OR THIN WORK
When planing short or thin pieces, always use push
blocks to minimize all danger to the hands. Fig. 40,
illustrates using the Push Blocks properly.
DO NOT PERFORM PLANING OPERATIONS ON
MATERIAL SHORTER THAN 10 INCHES, NARROWER
THAN 3/4 INCH, WIDER THAN 6 INCHES, OR LESS
THAN 1/2 INCH THICK (REFER TO FIG. 40A).
DIRECTION OF GRAIN
Avoid feeding work into the jointer against the grain as
shown in Fig. 41. The result will be chipped and
splintered edges. Feed with the grain as shown in Fig.
42, to obtain a smooth surface.
