RIPP_HG
Ripping is the sawing of wood with the grain. It is
generally done with the help of a fence as a guide to
position and maintain the work at the correct width for
the cut,, Because the work is pushed along the fence, it
must have a reasonably straight edge to make sliding con-
tact with the fence,. Also, work must make solid contact
with the table, so that it wil! not wobble, Provide a
straight edge, even if this means temporary nailing of an
auxiliary straight edge board to the work, If workpiece
is warped, turn the hollow side down°
Use of the saw guard is recommended; and thc splitter'
should always be used in ripping operations. Wood cut
with the grain tends to spring the kerr closed and bind
the blade. If for any reason, splitter is not used, stop and
insert a wedge in the kerr just as soon as cut has passed
back of blade.
Set fence to desired width of cut, either by using the
scale on the fence guide bar, or by measuring the distance
between blade and fence. Fence is almost always used
on right-hand side of blade,. Stand a little to the right
of center to avoid being sprayed with sawdust and to be
clear of work in case of a kickback, Start saw and ad-
vance work, using left hand to hold it down and right
hand to push it forwar& As cut nears completion, move
left hand to safe distance from blade, and push work
through with right hand alone. Never' reach in back of
blade with either hand to hold work down..
When there is less than the width of your pahn between
fence and blade, do not attempt to push work through
by hand. Use a push stick like that shown on preceding
page, or' pull work through from behind saw.
Do not leave a long board unsupported so t "h_t-the sprir,.g- ....
of the board causes it to shift on the table._ Use some
sort of support to catch end of board behind blade; and
if board is very long, use another support in front of saw.
RI:SAW HG
Resawing is the cutting of thick
boards into thinner ones. It is
a ripping operation, Small boards
-- up to 3_/[_-inchmaximum width
--can be resawed in one pass;
but larger boaids up to 61/vinch
maximum requke two passes, one
pass along each edge of the board.
When t_vo cuts from opposite
edges are required, these should

be made to overlap 1/2 inch from the approximate center
of the board. If the first cut is too deep, the kerr will
close and bind the saw on the second cut, with danger of
kickback, Also, when the kerr closes, the two sides of
the cut are no longer parallel to the saw blade, and the
saw will cut into them to spoil their appearance. Keep
same face of board against fence when making both cuts.
CROSSCUT?JNG
Crosscutting is the sawing of wood across the grain.
Planks are milled with the grain running the length of
the plank. In crosscutting the long edge of the work is
placed across the table top. Therefore, the miter gage is
used as a guide instead of the fence. Most operators pre-
fer to use the left-hand table g_oove In this case, the
left hand is used to hold the work in contact with the
gage and to push work and gage toward the blade, The
right hand is free to assist, as required° If right-hand
groove is used, hand positions are reversed.
Ordinarily the gage is placed in the table groove with the
bar in front. When work is so wide that it completely
