This past week I have been thinking about this very same idea. I need to get a feeder going this spring and have been considering the cheapo version of a feeder, but it's famous for dropping the feed onto the ground. So I have been thinking of ways to turn it into a floating feeder so it all gets into the water.
Thankyou esshup for mentioning how hard it is to fill this setup on the water. I was wondering about this. And of course the many maintainance issues with cheap feeders, I was considering making it so it could be pulled to shore easily for repairs and filling. As esshup mentioned, it sure can't be top heavy, and the weight changing as feed is added/used, changes the buyouncy and how it will sit in the water.
If I go this route I will be sure to take pics.
