Lortone Vibrating Flat Laps

Were designed to polish flat surfaces such as slabs, geode halves, bookends, and clock faces. Lortone vibrating flat laps are built of a heavy steel frame construction, with rubber supported pans and cushioned adjustable feet. New improved style oscillating flat laps are available in 15" or 20" models...These machines come complete with two pans: an aluminum grinding pan and a separate polishing pan with its own polishing pad. Pans are easily removable for cleanup. Suggested sequence for polishing: starting with 220 medium grit, 400 and finer grit, then 600 pre-polish and finally tin oxide.

Lortone's new innovative elastomer support system eliminates all of the old-fashioned lap parts - no more springs, balls or cables! The heavy gauge welded steel frame provides great stability and won’t walk around on the floor or bench.

Flat Lapping Tips - from Lortone, Start with a good cut. Nothing takes longer than trying to remove saw marks. Get your saw and blade tuned up and you will see a dramatic drop in your lapping times.

Use fresh grit. As the rocks grind down, the grit gets contaminated with rock dust and becomes less effective. By changing your grit every 4-8 hours you'll get maximum cutting efficiency.

Keep Everything Clean...We can't stress this enough. Any grit that is cariied over to a finer stage will cause scratches and prevent the stones from polishing. Make sure that there are no small rock chips or other items on the polish pad. Even household dirt can ruin an otherwise good finish. Keep your polish pan in a plastic bag.
