The stones you are intending to lap should be immersed in water for 2 to 3 minutes before starting work on them.
When lapping non-Shapton stones, you should ensure the stones absorb plenty of water first.
As a guide, use a pencil to draw a grid
on the stone surface to be flattened.
Place the plate somewhere stable
and splash it with water.
To lap a stone, lay it on the lapping plate and slowly slide it forwards and backwards, then diagonally, using the whole surface evenly.
Any time slurry accumulates in the grooves, rinse it off then resume lapping.
You can also lap a stone by laying the lapping plate on the stone.
In this case, you should slide the lapping plate forwards and backwards, then diagonally.
Parts where the lines get erased show where the lapping plate has made contact,
i.e. where flattening has been performed correctly.
Once you have finished lapping, rinse off any slurry promptly before putting the plate into storage.
We also recommend using a brush at this time.
