For lapping purposes all you really need is a turning wheel. I think you could modify a potters wheel to work. A large surface with grit and water turning slowly. If you watch the Adrenes videos they show one in it. Commercially there are vibrating laps available, those too should not be a big challenge if you had a good supply of tools and access to construction materials. I however live 100 miles past the edge of the earth. I would like to see someone else do it though.
