Alternatively, drilled and tapped holes in the
table top allow the use of wing nuts and washers
as a method of clamping. If this method of
fastening is used, provide slots in the feather
board for adjustment.
Figure 37 shows a method of attaching and use
of the feather board as a vertical comb. The
horizontal application is essentially the same
except that the attachment is to the table top.
Filler Piece (Figure 38).
A filler piece is necessary for narrow ripping and
permits the guard to remain on the machine. It
also provides space for the safe use of a push
stick.
Push Block & Push Stick (Figures 39 & 40).
These items help feed the workpiece along
fence and blade while keeping the operator's
hands at a safe distance from the blade.
Maintenance
Good saw operation requires periodic preventive
maintenance.
Keep the inside of the cabinet and trunnion area
clean. A stiff brush will remove sawdust before
it cakes and pitch or gum is easily removed with
a commercial solvent or with a good oven
cleaner. To accomplish this, remove the table
by removing the three mounting screws (see
Figure 15) and exposing the working
mechanisms of the saw. After cleaning the tilting
and raising worm and worm gear segments and
the trunnions, grease these three areas with a
good grade non-hardening grease.
Check periodically for excessive play in the
tilting and raising mechanism and in the saw
arbor and re-adjust as required.
Check periodical
l
y for belt tension and wear.
Readjust or replace belts as required.
The table surface must be kept clean and free of
rust for best results. Apply a coat of paste wax
to the surface to facilitate this. An alternative is
to apply white talcum powder, rubbed in
vigorously once a week with a blackboard
eraser; 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.
