I appreciate the suggestion and will try to find some of the references you mentioned. Photos or specific URLs would help as I'm not familiar with these terms or posts.

For now, I want to replicate Julian Edgar's early experiments with an NHW10 and I believe he used the Aerotabs. One concern I have is the part must be robust enough to survive the occasional, small hail storms we have and I have some loaner Aerotabs 'in the mail'. The advantage of a standard part is less 'do-it-yourself' folks can easily follow the same steps. But I have no problem with trying different approaches including a boundary suction manifold and pump.

Thanks,
Bob Wilson
