Learn how to weild a plasma cutter like a pro and you can slice through steel like butter
Building things from metal can seem intimidating—metal just feels so much more permanent than, say, wood, and with the all the sparks and pressurized cylinders, it seems like just a matter of time before you blow up your shop. But once you know your way around a few key tools, you'll be amazed at how simple metalwork can be. Case in point: the plasma cutter. This small, relatively inexpensive machine has one dial, no cumbersome gas tanks, and can zip through any conductive material faster than a jigsaw through pine. It's also basically a sci-fi machine made real (c'mon, it slices through steel with hafnium and air!). And since they're for sale in most big-box home stores, you can even put one on your X-mas list. Master this, and your metal creations can take on just about any shape you want.
