@ paus and Jim For that matter anyone else who would like to add their reply and input. In the previous reply, number 60, cao told and showed how he set up his sbb along with the size of the pan he uses. By the way (good looking job cao). Now my question to you two, Jim since you make your own pans, do you make them wall to wall and end to end? Or is yours placed kind of like cao's? Paus you are using the casserole type aluminum pans. What size are you using? I am assuming yours are not wall to wall and end to end because you are talking about moving your pans to the later part of the entrance for the sake of preserving pollen? Both of you are having success with your pans. I am just interested in the diversity of different designs. Thanks for your input. Sincerely, Phillip Hall
