Hello again, Well no luck at the auction. I did however just pick up 28 CCA 12 foot 2x6's and 32 CCA 8 foot 2x6's for 25.00. I also have lot's of other 2x6's and 2x8's I already collected. My plan as stated above is to build a 16x24 dock. I would like to make it 24 long on the shoreline and 16 feet out into the water. Because the water is so far down right now most of my post holes will be dug above the water line. I am trying to figure out how far apart to space my posts if I use 2x8's for the frame. I have plenty of post's so using a lot doesn't matter. Should I place 1 every four feet or can I get away with eight? Oh Ryan, thank you for the info on bin flooring. I will have to look into that and consider it for future projects. Thanks again guys
