How Do You Cast an Object That Has Holes?

Many makers are intimidated by trying to do any molding and casting. But how about casting a part that is riddled with holes? Yikes.

But fear thee not. Bob Tolone to the rescue with this excellent video.

Besides the successful cast of this difficult part, there are lots of great tips in this video, from using spinach clam shell plastic containers for storing parts, materials, and supplies to using pieces of bent polystyrene, binder clips, and silicone-as-glue to create reusable mold boxes.
