Let the fun begin.. I have started building the floats for my 4" and my 2 1/2" dredges. I am using the material that Doc from Gold Hog used to build his. From his calculations the floats should float 640lbs total and I will use half for the 2 1/2". Since I don't know how much shoveling I will be able to do since my surgeries I do know I can float to use the dredge. I can have a battle of the dredges with my daughter Erica and we should be able to move more dirt..
