Tips for Using the Logan Oval and Circle Mat Cutter

The following tips for using the Logan Oval and Circle Mat Cutter Model #201 will detail step by step how to operate the product.

Step One: Set the Shape of the Oval or Circle

The design of the Model #201 Oval and Circle Mat Cutter has a bevel cutting head mounted to an arm that rotates around a stationary base. A cam-shaped plate with an adjustable mid-point allows for the setting of different ellipses. Each shape is determined by adjusting the scale inside the base for the difference between the height and width of the window you want to cut. For example, if you want to cut an 11″x14″ oval, you set the differential scale to 3″ because 3 is the difference between 11 and 14. If you want a shorter, squatter oval, an 11″x13″ is called for and the differential scale is set at 2. By changing the difference between the height and the width, you change the shape of the oval. By changing the difference between the height and width to zero, you are setting up to cut a circle.

On the rotating arm, you will find a separate scale. The cutting head is slid along this arm and locked down at the point on the scale indicative of the narrow dimension of your oval. For example, if you want to cut an 11″x14″, you set the scale on the arm to 11″. When the differential scale is set to zero, the scale arm setting indicates the diameter of the circle you will cut.

Step Two: Position the Cutter on the Mat

On the face of the mat mark a large plus sign (larger than the base) where you want the middle of the oval window to be. Note: Unlike other mat cutters, oval and circle mat cutters are designed to cut on the face of the mat.

Step Three: Anchor the Base to the Mat

First, place a second mat of the same size under the mat you are going to cut. This second mat is the backing sheet. Without it you will cut through your mat and into the table top. Next, arrange the base over the plus sign, aligning the white marks on each side of the base with the arms of the plus sign. Caution: the base must be oriented to the mat the same way the window will be oriented to the mat. For example, in most cases you don’t want a horizontal oval oriented to the vertical axis of the mat.

Press down firmly on the base with the heels of your hands. The pins under the base will sink into the mat helping to anchor it. However, the pins will not be adequate to hold the base in place once you begin cutting. During cutting you must always hold down firmly on the base with your left hand.

Step Four: Allow the Cutting Head to Swivel into the Starting Position

The cutting head is mounted on a pin under the scale arm and is designed to swivel. Without the ability to swivel it would be impossible to cut different shaped ovals. Before engaging the blade, it’s necessary to allow the cutting head to swivel into position for the ellipses you’ve got set. Holding down firmly on the cutting head, rotate the scale arm around the base. Do not engage the blade. The cutting head will roll forward on its tracking wheel and swivel to assume the curvature of the oval. Caution: the scale arm must only be rotated around the base in a clockwise direction. Caution: do not allow your fingers to touch or obstruct the swiveling cutting head, doing so will prevent the cutting head from swiveling into position and will result in a frayed cut.

Step Five: Engage the blade

With your thumb resting lightly on top of the cutting head, lift the stepping lever until it clicks into the first step. You will feel it click in. The blade is now engaged. Caution: You are now at the most critical stage in the process. Anything you do to block or obstruct the swiveling cutting head will result in a frayed cut. Do not let your fingers touch the swiveling cutting head as you rotate the scale arm. However, to achieve the best results rest your thumb lightly on top of the cutting head as you rotate the scale arm.

Step Six: Cut the Mat

Rotate the scale arm around the base making a light initial score in the surface of the mat. The cutter is not designed to cut through at this point. Do not exert downward pressure with your thumb on top of the cutting head; rather, let it rest lightly there as you rotate the arm. Keep your fingers well out of the way of the swiveling cutting head. Rotate the arm past the point where the score joins itself before going on to the next step.

With your thumb resting lightly on top of the cutting head, reach down with your index finger and lift the stepping lever to the next step. Rotate the scale arm around the base again. You will feel an increase in resistance as the blade cuts more deeply into the mat. Rotate past the point where you started.

Lift the stepping lever to the final step. Rotate the scale arm around the base two or three more times. You cannot cut too many times; you can only fail to cut enough times to penetrate the mat. During the final rotations you can exert moderate downward pressure with your thumb on top of the cutting head to cut through.

Disengage the blade and lift away the drop out piece. Your oval window is complete.
