Polish bookends, large slabs of petrified wood quickly using the Diamond Pacific diamond rotating disc flat lap 12" size (12 RLD Diamond) with machines modified for use with Magnetic Novas Laps. Save time polishing large flats in two ways. First, the actual polishing process for each step is reduced by the speed and efficiency you get using our resin-bond diamond Magnetic Nova Laps. Under normal circumstances, it only takes 14-25 minutes for each grit step to polish your large flat. Second, you save time by not having the usual clean-up between grit changes. Changing grits with Magentic Novas simply means removing one flexible lap from the back-plate and installing the next - taking only a few moments at most. Since the diamonds in Magnetic Novas are permanently bonded to their working surfaces, there's little chance of contamination. Recommended general-purpose grit sequence is 60, 280, 600, 1200 grits, followed by the new Super Premium Cerium Oxide Polish on a felt pad. Also recommended is the use of a 60 grit Diamond Dura Disc to precede the 60 grit Magnetic Nova for those slab surfaces with deep saw marks or other features requiring grinding preparation. FEATURES FOR THE DIAMOND RLD MODELS: Models come with motor, adjustable drip tanks, and aluminum back plate. Arbor shaft is 1". Bearings are 1", factory lubricated and sealed to prevent contamination. Powder coated, heavy duty fabricated steel plate boxes.
