Super easy plate holder. This is a 6.95 dumbbell bar from Walmart. Take a grinder and cut off the plastic grip. This leaves a solid, 1-inch all-thread bar with two nuts. Pop a 1-inch hole in anything sturdy enough to handle the weight of the plates. Put a nut on both sides of whatever you mount to. I was thinking about making a sawhorse and having a portable plate holder. But you can put them almost anywhere sturdy enough to hold the weight.
