Laps Designed to polish slabs, geodes, bookends, and clock faces. Heavy steel frame construction. Complete with separate grinding and polishing pans. We suggest starting with 220 grit, then 600, and finally Tin Oxide. 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. We can't stress this enough.
