TAPER CUTS

One of the most useful jointer operations is

cutting an edge to a taper. The method can

be used on a wide variety of work. Tapered

legs of furniture are a common example.

Instead of laying the piece on the infeed

table, lower the forward end of the work onto

the outfeed table.

Do this very carefully, as the piece will span

the knives, and they will take a "bite" from the

work with a tendency to kick back unless the

piece is firmly held. Now push the work

forward as in ordinary jointing.

The effect is to plane off all the stock in front

of the knives to increase depth, leaving a

tapered surface. The ridge left by the knives

when starting the taper may be removed by

taking a very light cut according to the regular

method for jointing, with the infeed table

raised to its usual position.

Practice is required in taper operations, and

the beginner is advised to make trial cuts on

waste material. Taper cuts over part of the

length and a number of other special

operations can easily be done as the operator

gains experience.

MAINTENANCE

WARNING: Disconnect machine

from power source before

performing maintenance.

Check all screws and fasteners occasionally

and keep them tightened securely.

The table and fence surfaces must be kept

clean and free of rust for best results. Some

users prefer a paste wax coating. Another

option is talcum powder applied with a

blackboard eraser rubbed in vigorously once

a week; this will fill casting pores and form a

moisture barrier. This method provides a

table top that is slick and allows rust rings to

be easily wiped from the surface. Important

also is the fact that talcum powder will not

stain wood or mar finishes as wax pickup

does.

LUBRICATION

Use a high grade light grease on the steel

adjusting screws for the raising and lowering

mechanisms of the infeed and outfeed work

tables.
