Total Polishing System EDCO3 Diamond Blocks with 5 piece segments (3 Packs)

These blocks would be awesome if they weren't shoddily assembled and cast. The blocks have squared edges which should be slightly rounded to fit snuggly in the Edco base. The spring load is nice but they I had to take them apart to clean the rust and the painting overspray to allow them to operated freely. If you get these and there is no spring action, take them apart and grind and sand the castings until they fit and move freely. If you don't, they will fly off your machine at every pass.
