In order to create the finest degree of detail on RealSpace models, some of the kits include parts made of photoetched brass. Not every kit has these parts, but if the kit you purchased has them some special handling and precautions need to be followed. Some of the photoetched parts or the surrounding brass may be sharp. To cut the parts from the surrounding metal it is best to use an x-Acto type of hobby knife and cut on a hard surface. Be sure to secure the part being cut to keep it from flying across the room when cut.
Some parts require folding or bending to form the metal in to the correct shape.
This is best accomplished with a needle nosed pliers. Work slow and don't try to bend it all at the same time. Several small bends is better than one large bend. For parts that need to be rolled into a circle, use a dowel rod to press the part out into it's correct shape. For longer parts that need folding, a metal straightedge can be employed to bend the part all at once.
