The ability to make castings adds great potential to a workshop or art studio, yet few people get into it. The techniques aren’t difficult, but they are unfamiliar. Pyramid makes it easy to understand and do; their kits set you up with supplies, equipment, and instruction. I’ve seen the sets used for boat restoration, machine repair, and making antique auto parts. The projects were successful, though there was certainly some time spent learning the hard way. Even that wasn’t too bad; you can recast your boo-boos. The sets can handle aluminum, bronze, grey iron, and jewelry metals.
