Yes you can lap with W&D but dragging a new piece of W&D and a flat plate and water each time is a pain in the buttocks.
And for the price of the lapping plate… that does not work as quickly or efficiently, you can buy a good lapping plate that will last many many years.

Look at the 330mate plate for 20-30 or for about $50 a DMT or I Wood plate.
A DMT lapping plate is expensive. Are you suggesting a DMT D8C? That's a 325 whetstone. Can I lap with it?
