How to Cut a Bevelled Edge Window Mount using a Trio System

To Cut the Mountboard Sheet Down to Size

Set up the system on a firm work surface and remove the Trio Guide Rail. Take out the Cutter Stops, turn the Trio Guide Rail over, remove the Mount Stop by slackening the screw with the screwdriver and then unlock the cam. Now replace the Trio Guide Rail, set the parallelogram to maximum and insert the sheet of mountboard face down under the Trio Guide Rail and up to the Squaring Pins. Measure out the correct size using the tape measure. Remove the Safety Guard, hook the Vertical Cutter onto the Guide Rail and push away from you in one smooth action.



Be positive – don’t hesitate, otherwise the blade may flex resulting
in a curve at the end.

The blade is very sharp so always remember to replace the Safety Guard after each cut.

The groove in the Base accommodates the blade of the Vertical Cutter as it cuts. It is only for use with the Vertical Cutter – not the Bevel Cutter.

To Mark Out and Cut the Bevelled Edge Window

The Bevel Cutter is used to produce the pleasing angled cuts which are the feature of quality picture mounts.

Set the parallelogram to the border width required using the narrow scale for borders up to 70mm or the wider scale for borders up to 130mm.

Using the narrow scale

Insert the Mount Stop into the back of the Trio Guide Rail at a comfortable cutting position, taking into account the size of the mount, but set the Mount Stop so that it does not interfere with the Z shaped plate. Place the Trio Guide Rail onto the Base.
Slide the SprintMat under the Guide Rail, across the whole Base and up to the Squaring Pins.




Using the SprintMat is essential when bevel cutting as the blade must cut into a supportive substrate to achieve a clean, accurate bevel cut.




Slacken the central knob and using the black indicator line on the Z plate against the short scale, move the Z plate to the required border measurement and lock the knob.
Now insert the mount blank face down under the Trio Guide Rail, on top of the SprintMat across to the leading edge of the Z plate and up to the Mount Stop.
Mark out the four border lines using a pencil against the Trio Guide Rail edge.




Ahard pencil, say 4H, helps produce the fine lines needed for accurate cutting.




Place the Bevel Cutter onto the Trio Guide Rail and insert the two Cutter Stops.Before cutting, line up the centre of the V with the finish line and lock the top stop; slide the cutter back and line up the centre of the V with the start line and lock the bottom stop.




The cutter stop is set by positioning the centre of the V on the intersecting line and then locking it in position.




Place one hand on the Trio Guide Rail for your support and with the Bevel Cutter held firmly against the bottom stop with the other hand, place the palm so that it covers the top of the cutter, rotate the blade fully into the mountboard with the heel of your hand and then push the cutter to the other stop in one smooth action.




ensure the SprintMat always supports both the rail and cutter






Manually retract the blade fully and take the cutter off the Trio Guide Rail. The cutter stops of course remain set for the opposite long side (if cutting a rectangle and for the other three sides if cutting a square mount). Turn the mount around and repeat the cut. Reset the bottom stop and repeat for the shorter sides if cutting a rectangular mount.

In just a few minutes you will have produced a professional quality mount that will set off any photograph, painting or picture.

                                    

Using the wider scale

If you wish to create a border wider than 70mm, place the SprintMat under the Trio Guide Rail and slide it across to the leading edge of the Z plate and up to the Squaring Pins. Insert the mount blank face down on top of the SprintMat but this time slide it right across to the back of the Z plate and up to the Mount Stop.
You are now ready to mark out the borders and cut the window aperture as before.

For larger mounts remove the Mount Stop and slide the mount blank up to the squaring pins instead

Trio Maxi guide rail




Use both parrellolgrams in tandem for large mounts but only
the parrellolgram nearest to you for smaller sizes.

To Mark Out the Window Border using the Marker Gauge

With the mountboard face down, mark out the window border in pencil to provide a cutting guide. Set the measurement of the Marker Gauge to the required width for the border and draw four lines If you are cutting a dropped border (that is one where the border at the bottom is wider than at the top and sides), you will need to adjust the Marker Gauge to mark out the wider border.


place the mountboard on the worksurface just over the edge and keep the yellow block firmly up against the side of the mountboard when drawing the line

a hard pencil, say 4H, helps produce the fine lines needed for accurate cutting.
