Fasten the coving fence to the rip fence and adjust the angle parallel to the three reference lines. Then move the rip fence sideways until it's the proper distance away from the lines. When the fence is positioned, turn on the saw and raise the blade.

shows the steps to set up your fence on the saw. Remember to place the fence or straightedge on the infeed side of the blade. The rotation of the blade helps hold the stock against the fence.

Adjust the saw blade so it projects no more than VV above the saw table. Turn on the saw and place the workpiece against the fence. Slowly feed the workpiece from the infeed side of the saw and against the direction of rotation. After completing the first pass, raise the saw blade another VV and make a second pass. Repeat until you have cut the cove to the desired depth and width. On the last pass, feed the wood very slowly - this will make the surface of the cove as smooth as possible and reduce the amount of sanding needed.

Cutting Odd-shaped Boards

Occasionally, you will need to rip or crosscut a board that doesn't have an edge straight or square enough to hold against the rip fence or miter gauge. Sometimes the board is crooked or warped, other times it's cut or shaped to a particular pattern or contour. The best solution would be to straighten one edge before you cut, but there are times when you can't do this for whatever reason.

To safely cut an odd-shaped board, mount it on a holder that has at least one good guiding edge. This holder doesn't need to be a complex affair; a scrap of plywood with several straight edges makes an excellent holder. Nail the workpiece to the plywood or secure it with double-faced carpet tape. Place the holder against the rip fence or miter gauge, and feed both the holder and the workpiece past the blade (shown below).

To cut an odd-shaped piece that has no guiding edge, secure it to a rectangular scrap of plywood with nails or double-faced tape. Place one straight edge of the plywood against the rip fence or miter gauge, then guide the piece over the blade, cutting both the plywood and the piece.
