Skewing (Shear Cutting)<br />

When edging or facing burl or birds-eye maple,<br />

it is not unusual to deface or mar the surface<br />

being finished. This is caused by the cutterhead<br />

knives occasionally cutting against the grain. In<br />

order to prevent the defacing or marring of this<br />

type wood, it is necessary to skew, or angle<br />

finish, the material being worked.<br />

Refer to Figure 36.<br />

1. Release the fence locking handle (A, Figure<br />

36) and remove the hex nut and washer (B)<br />

holding the fence to the fence support.<br />

Remove the fence assembly.<br />

2. Remove the key (C) and the 1/4”-20 x 1/4”<br />

socket head cap screw (D) from the fence<br />

support. (The socket head screw keeps the<br />

non-mar insert from hitting the key.)<br />

3. Position the fence assembly at the desired<br />

angle across the cutterhead.<br />

4. Secure the fence to the support with the hex<br />

nut and washer (B), then tighten the fence<br />

locking handle (A).<br />

When resuming work with normal stock, always<br />

re-install the key and the socket head cap<br />

screw!<br />

Taper Cuts<br />

A useful jointer operation is cutting an edge to a<br />

taper. The method can be used on a wide<br />

variety of work. Tapered legs of furniture are a<br />

common example. Instead of laying the piece on<br />

the infeed table, lower the forward end of the<br />

work onto the outfeed table. Do this very<br />

carefully, as the piece will span the knives, and<br />

they will take a "bite" from the work with a<br />

tendency to kick back unless the piece is firmly<br />

held. Now push the work forward as in ordinary<br />

jointing.<br />

The effect is to plane off all the stock in front of<br />

the knives to increasing depth, leaving a tapered<br />

surface. The ridge left by the knives when<br />

starting the taper may be removed by taking a<br />

very light cut according to the regular method for<br />

jointing, with the infeed table raised to its usual<br />

position.<br />

Practice is required in taper operations, and the<br />

beginner is advised to make trial cuts on waste<br />

material. Taper cuts over part of the length and<br />

a number of other special operations can easily<br />

be done as the operator gains experience.<br />
