Yep! I used the plans Jon McFadden had posted last year. Worked great! I used it on my ferals and this year on a weak hive (my ineptness) I guess I should say workS great! Here's a pic. The far hive had it last
I used 1"x2" and black nylon window screen. Took about an hour to get everything together, measure, cut, and screw together. I removed it to measure for use with entrance feeder from Betterbee (not boardman) using 1"x1" wood when I had a robbing incident within a surprisingly short time. A sprinkler helped stop it until I replaced the screen.
But it seems to work great for me.
