PLEASE NOTE: the rotating disc flat lap 12″ Model is a great unit. Polish bookends, thundereggs, end cuts, large slabs of petrified wood, etc.  There are two ways to use this unit,  use the standard lapping process for stone, glass or optics on the cast iron lap plate with a series of silicon carbide or other abrasives. Standard grit sequence for most purposes is 60/90, 220,  600 pre-polish, and then polish. Then there is the use of Diamond Magnetic Novas for the fastest  and most efficient way to polish large slabs on the RL lap machines the Diamond Pacific diamond rotating disc flat lap 12″ size (12 RL magnetic plated diamond discs, 1/3HP, 115V-60Hz). The Rotating Flat Laps are rugged machines from cast iron lap plates to metal tanks. They will give years of service. 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 Magnetic 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. Standard magnetic Nova’s do not come with arbor holes unless requested. Recommended general-purpose grit sequence is 60, 280, 600, 1200 grits, followed by the new Super Premium Cerium Oxide Polish on a felt pad. Diamond Magnetic Nova laps for the 12″ model run $191.40 each (minus a discount) for each grit as follows: 30, 60, 140, 280, 600, 1200, 3000, 8000, 14,000, 50,000.) The use of a 60 grit Diamond plated disc is recommended 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 RL 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. The 12 RL measure approx. 15″ x 15″ x 13 3/4″ with a 6 3/4″ deep tank, 1/3 HP, 115V-60Hz. (Shipping weight 144 pounds.) The RL model flat laps run at speeds suitable with the use of abrasive grits on the rotating plates, and for use of Magnetic Novas. Machines with variable speed motors are generally not needed, but are available as a special order. (Crating fee of $120.00 will be added to the purchase.) Using the standard lapping process: if you need to precision grind and polish a flat surface on stone, glass or optics, use the cast iron lap plate of the RL lap, and a series of silicon carbide or other abrasives.  The rotating cast iron plate is built to fulfill the fundamental requirements of precision lapping with maximum stability and wheel balance. Lap plates are machined to exacting tolerances and grooved with concentric V-groove circles for retention of the abrasive.  Standard grit sequence for most purposes is 60/90, 220, 400, 600, 1000, followed by a polish such as Super Premium Cerium Oxide is recommended. and available in 4oz., 16oz. and 5 lbs.  For the final polish purchase a felt magnetic polish pad 12″ listed at $34.95.  Weight  of the Rotating Disc flat lap is 144 lbs.
