Hey, Dan, thought I'd jump on here since you haven't gotten any feedback yet. Could you clarify what it is you would like to do? I'm just assuming from your post that you're looking for a surface floating type of mechanism to try to sweep your DW into one spot for manual removal. Is that accurate? Maybe some more detail would help in generating more responses.
