My Royson 1.5 cu ft machine is great. Except the urethane liner sides are flat and smooth. Any part with even a little flat section will stick to the sides via suction, and just ride there and not get deburred. Could I glue a ribbed sheet of urethane to the sides that are there? Special glue? Mcmaster sells sheets, I could probably get one that's 3/8" thick and either mill or cut grooves with a rotary burr. Anybody has similar issues with a vibe-deburr machine?
