The Mag Hand Workstation[Amazon link] by Hobby Creek is a 4.5 Lb steel platform with flexible, magnetic arms that hold delicate objects in place while I paint, solder and study them. Since my side projects involve tiny antiques with itsy bitsy locking mechanisms, I used to have a habit of losing important pieces – but those days are behind me.
My Hydra-like workstation comes with 2 magnetic trays that can be positioned anywhere on the platform.
And because of built in magnets, even if tip the whole thing upside down, everything stays put. The pieces are modular and allows me to set the flexible matrix in any way I want. In fact, the arms and optional Mag Helper can simply be used by themselves when placed on any steel object.
Check out Hobby Creek if you enjoy delicate work but don't like crawling around on your hands and knees looking for tiny, lost metal things.
