7.6. Rip Cuts

Ripping is where the workpiece is fed with the grain into the saw blade using the

fence as a guide and a positioning device to ensure the desired width of cut.

While all table saws are capable of rip cuts, our preference is that the Delta saws be the primary ones

used for rip cuts.

Keys to safe, accurate rip cuts include:

1) Have a sufficiently long straight edge against the fence. The

side of the wood against the fence must be straight or the

wood can rock while engaged with the blade, creating

potential for kickback. If the wood to be cut does not have at

least one straight edge, it should be jointed to create one.

2) Use a good push handle or push pad to guide the wood

through the blade.

The size of the piece being cut is also important:

• Small pieces of wood are exceptionally difficult to control while being pushed across the table

saw blade. When confronted with a piece of wood less than 12” long, use another machine,

like a band saw to make the cut.

• Ripping narrow pieces can be dangerous. If possible, rip the narrow piece from the larger piece.

Use one or more push pads or push sticks to avoid placing your hands between the fence and

the blade. Always use care to avoid binding narrow strips between the anti-kickback pawls and

the splitter.

• Another common problem area is trying to control a long piece of wood. The Woodshop has

large outfeed tables on our table saws, so this only applies to really long pieces. When the

length of the wood dictates, ask the Shop Monitor or another woodworker to assist – this lets

you concentrate on making the cut, not on catching the wood on the other side of the blade.

Making the cut:

a) The rip fence should be set for the width of the cut by using the scale on the front rail, or by

measuring the distance between the blade and fence. Stand out of line with the saw blade and

workpiece to avoid sawdust and splinters coming off the blade or a kickback, if one should

occur.

b) If the wood to be cut does not have at least one straight edge, joint it first to create one.
