I hope you did
not put Rain-X on the
Bird
Pokers!! The surface are of those things will
drastically increase the total surface area used to capture and divert it into the buckets and increase the recorded rain values!! I suggest you add some very small disks (material and color of your choice) and mount them near the bottom of each
BP. Be sure to drill the needed hole at about a 47.35? angle so they tilt downward on the
BP. This will help divert any water draining down the
BP Obviously, you should take care to have all these mini-divertors have their lower part away from the funnel. These mini-divertors needn't be more than a quarter inch in width, just large enough to prevent any drops from creeping over he high side. My mini-divertors are slightly concave with the 'bowl' facing upward. I find this also helps prevent stray droplets from escaping into the funnel. You may not want to do that much work, but I would encourage you to file down any burrs on the edges (preferably before you mount them) as these can facilitate droplets ignoring the slopped surface and ending up in the funnel!. Detailed engineering drawings and more detailed instructions are available for a small handling, printing, and shipping fee (no checks, please).
Should you decide to ignore my suggestions, I hope you will, at least, file the tops of the
BPs at an angle (slopping toward the outside of the ISS, of course)! sThis will assure that any drops hitting the
top will be 'encouraged' to continue its downward trajectory away from the funnel! After all, it's the least you can do in the name of scientific excellence and accurate data collection!
