So these are made out of brake disks I cleaned up. They were caked with rust so I soaked in vinegar for a few days. Used a brush and the rust just slid off. Rinsed, dried then coated with some truck liner spray to protect the metal. Inserted a piece of 2 inch PVC in the center. This size fits perfectly around an Olympic style barbell. Then filled with concrete. Once dry I used epoxy and BBs to even the weight out. Original weight for each was exactly 35.01lbs on a shipping scale. I have made several weights like this and will post more eventually. All in all I’ve saved myself hundreds on just making myself weights.
How many of these do you have?
Pairs of 35s, 25s, 20s, and 15s. I also have some 10s and 5s made out of just concrete and PVC. Also dumbbells made with concrete filled cans and steel pipe.
