Review on 🔧 Grommet Guru: Unleashing the Power of MEZOOM's Diameter Setting Projects by Derek Kraft

This kit works like a charm if you follow a few simple laws of physics. First, make sure the hole for the bushing is on a piece of high-density wood on a hard surface. You don't want to minimize the recovery (bounce) factor. When installing the sleeve, make sure that it is also standing on a solid object. I used an anvil which I doubt most people don't have. However, any hard surface will do.
