How to Cut Rigid Projection screen sheets correctly.
Cutting with a knife or scriber
Rigid Projection sheets may be cut by a method similar to that used to cut glass. Use a Stanley knife, to score the sheet. Draw the Blade several times along a straight edge held firmly in place. Then clamp the sheet or hold it rigidly under a straight edge with the scribe mark hanging just over the edge of a table. Apply a sharp downward pressure to break the sheet along the scribe line. Scrape the edges to smooth any sharp corners. This method is not recommended for long breaks.
Cutting with power saws
Special blades are available to cut acrylic and plastics. Otherwise blades designed to cut aluminum or copper work OK. Teeth should be fine, of the same height, evenly spaced, with little or no set.
Table and circular saws
Use hollow ground high speed blades with no set and at least 5 teeth per inch. Carbide tipped blades with a triple chip tooth will give the smoothest cuts. Set the blade height about 1/8" above the height of the material. This will reduce edge chipping.
When using a hand held circular saw, clamp the sheet to the work surface and use a length of wood to distribute the clamping pressure and act as a guide for the saw.
Hand saws
Good results are possible, but can be difficult. Be sure the sheet is clamped to prevent flexing. Flexing at the cut may cause cracking and you don't want that do you!
Cutting Flexible projection screens and Films.
Our PVC and Film projection screen materials can be cut with a Stanley (Craft knife), or using sharp scissors. Use a straight edge for the blade to folllow, or to mark a straight line and follow with scissors.
