When I started researching how to build concrete weight plates and dumbbells I was surprised to see how expensive it was to purchase molds for custom concrete weights. In today's video I'm going to make hand made molds from melamine and plywood so that you're able to outfit your gym with these homemade 45 pound (or any size) concrete plates. Standard cast iron plates have a weight tolerance of 1-2% and these 2 weights are within 1% off from each other which means its a success!

MODERN BUILDS
Hi, My name is Mike Montgomery and I'm a MAKER; a designer, builder, and full-time content creator. Accessibility is my focus with Modern Builds, not simply accessibility of designs, but accessibility in materials, information, and projects themselves. I've focused on creating furniture and DIY projects that are simple enough that any beginner maker can accomplish, yet interesting enough that any expert might be inspired. Building and making is becoming less and less of an exclusive hobby and profession. My goal is to reduce that separation even further.
