Bevel cutting
NOTE: If the size of the oval does not reflect the sizes set refer to the next
Vertical cutting
The vertical blade is of the same type as that used for bevel cutting (SM02 or SM03 for
small oval/circles) but held in a different slot in the blade holder. The blade depth is not
as critical but should be long enough to cut through the material without the base of the
blade holder touching the surface of the matboard and not so far extended that the
blade tip bends when cutting.
Use the same procedure as explained above, a cleaner cut will be produced by placing
the matboard in the machine coloured face down as the thickness of the vertical blade
can displace the edges of the cut upwards producing a small burr on the coloured edge.
