For jointing and planing cuts pressure is directed

three ways; into the fence to ensure a square

cut, forward to advance the stock, and

downward to avoid chatter and vibration.

For jointing when the material is higher than the

fence, the left hand applies pressure into the

fence and down toward the table while the right

hand pushes forward from behind. Be sure to

keep the right hand high up on the material.

(Fig. 28)

For jointing material that is lower than the fence,

use push sticks to protect the hands. For

planing, use handle pads. (Fig. 29) Never

place the right hand on the trailing edge of

the material. Hand placement on the trailing

edge of the material may cause the hand to

come into contact with the blade.

Feed work from right to left at a steady,

moderate speed. If you feed the material too

slowly, the wood will burn in places. If you feed

the material too quickly, ridges will appear in the

finished surface.

Jointing Warped Material

If the work to be jointed is cupped or warped,

take light, repetitive cuts until the surface is flat.

Forcing the material flat against the table will still

leave a warped piece after the cuts have been

made.

Never joint any material

shorter than eight inches! The material may

tip into the jointer’s throat and be kicked

back! Avoid jointing thin material which

could become jammed under the fence or

blade guard! Failure to comply may cause

serious injury!

Direction of Grain

Feed the material with of the grain to avoid

tearout (Fig. 30). If the direction of the grain

changes somewhere in the board, try reducing

depth of cut and slow the feed speed down to

avoid tearout. If results still aren’t satisfactory,

turn the material around and try feeding through

the other way.

Bevel Cut

To cut a bevel, lock the fence at the desired

angle and run the material through, pressing the

work firmly against the fence and tables (Fig.

31). Several passes may be necessary for the

desired result.
