Protips:
DO NOT OVERSPEED the Dreamer lap: They are designed for use at speeds < 900 rpm (and higher speeds are not required or optimal).
Use plenty of water with the Dreamer to keep swarf washed from the working surface.
The Dremer lap may be slightly domed from the factory. If you wish to flatten the dome (or de-glaze one that’s become shiny) you can resurface the lap using a flattening stone as shown in this video.
