Dear All, I have decided to take a few minutes to describe a simple device which I made many decades ago (just after fridge magnets appeared) to hold pinned insects or parts of plant material (flowers, moss, lichens, liverworts...) mounted on insect pins for examination using a dissecting mike. The Styrofoam disk has not required replacement after much use. Materials: A strip of sheet iron 16 mm wide, 9.7 cm long and 0.6 mm thick; dimensions are not critical. A disc 20 mm diam, cut from a fridge magnet. A 14 mm square of Styrofoam, cut from a 5 mm thick meat tray. Insect pins. Assembly and use: Bend the sheet iron strip at 90 degrees to form two arms; 4 cm and 5.7 cm long Glue the Styrofoam square to the fridge magnet disc. Because the diameter of this disc is slightly greater than the width of the iron support one can readily raise, lower or rotate the object viewed to the desired orientation. The long arm of the sheet iron holder is upright for examination of unusually large material; otherwise the short arm is upright. YT, DW, Kentville
