Building a copy of this over the coming weekend for my 50 year old well established farm pond. These are heavyweights at 60 lbs of concrete and was thinking about using half the concrete (30 lbs.) and then taking treated lumber (1 x 6) and attaching a cross (X) of that lumber to the bottom of the bucket (before putting in the concrete). Each leg of the cross would be 2 feet (cut an 8 foot 1 x 6 into four pieces). Would certainly be easier when lowering over the side of a john boat at the appropriate location but would it be steady enough not to tip over once it is in the water and on the bottom? Soft muddy bottom for most of our old farm pond. Should the cross lumber on the bottom be longer than 2 ft? Thoughts? Thanks...first time poster/new PB subscriber....wish I would have stumbled on PB and this forum years ago.
