First wagon i built this year, its outta ash, all rough cut from amish farmer in NY. Its 8X16, 4x8 main beams, 4x4 cross beams, 1.25 deck, 2x4 uprights. All lumber was cut to a full 17.5 feet except uprights, they were 8.5 ft long. Think it turneed out ok, still need to cut sides for doors and install cahins.steel side braces are installed, and a 38H gate on front. Holds about 130 bales.
