Nothing is more frustrating that working with small parts, springs and screws, except when you dump them all on the floor! I like to use a pottery or stainess bowl to put my parts in....after I toss in a cow magnet. If it all goes off the table, the magnet will hold the parts. you can go one better and hot melt glue the magnet into the bowl. Cow magnets are slick little gizmos that vetrinarian and farmers feed cattle who might have injested metal parts, the magnet holds the metal in one place so the guts don't get too torn up.
The other trick I use for small parts is a wood block with fresh duct tape wound on it with the sticky OUT. You have to place each part or screw, but they don't go anywhare.
