okay... questions woodman ... (keep showing me different machines and I'm gonna keep asking questions!) That polishing lap - is that a steel plate with polish on it, or what is the polishing surface? The rock being polished seems to be sitting still. Does the rock have to be moved around during polish to get different angles while it is sitting on the polishing surface and to a better shine, or will it shine up just fine sitting stationary like that? I don't know the name of that arm on the lap at the far right of the video, is its purpose to move the rock (more than that one seems to be moving) so it does not sit in one spot? How long does the polishing step take - different for different rocks? Any reason, other than speeding things up, that one of those flat laps can't take rocks through the entire process? Sorry about all the questions, just like to understand how all these machines work.

Sorry about all the questions, just like to understand how all these machines work. Questions are fun when I think I know the answers!! The plate is steel with a layer of carpet pad and a top layer of 100 percent wool carpet, with a cerium oxide slurry poured on. The little motor on the right moves the cross frame to move the rock a bit. At time I do have to reposition the rock to get a complete polish. By the time you get the rock off of the bull wheel, the final polish goes pretty fast, depending on the type of rock and how often you reposition it. I lose track of how long it is on the polisher but 30 40 minutes at the most. The flat lap machine they way we use it does not complete the process and the bull wheel is required before polishing. As you so we can do number of pieces at the same time on the flat lap and the polisher.
