Just use cardboard or plastic sheet or sheetmetal (from the air conditioning guys) depending upon your whim. You aren't trying to stop anything that has any strength except what you throw (it's not nice to drop an EP on the primary) down the tube. The big thing is to use a compass to make the circles and to cut carefully. Bob May
