building a quad trailer for a guy,he wants to put three quads across the deck,side by side.
he's got a car dolly for the axle,but it's 78'' between the wheels and i want the deck a little wider so the quads won't be hanging over the edge.that's why the square kick-in is in the middle(these are the side rails)
i've also found that when walking around trailers like this i have a tendency to bump into the corners with my knees,so i like to miter them to a short 45*,just enough that it isn't sticking out so far.
although i used my little mig to tack the pieces together i'm doing all my finish welding with stick,using 7018 1/8'' rod.this is a good high strength rod with good penetration,and is cheap to weld with and easier than dragging the wirefeed around.
the frame is 2x4x1/8'' hss,and will have 1 1/2 x3 x1/8'' hss crossmembers ,as well as a 1 1/2x1 1/2 x1/8'' angle iron ledge to hold a 3/4'' plywood deck flush with the top of the steel.
i'll post more as it progresses.
