My buddies and I are building a decoy cart for this season as we've got a few new spots that we can't drive in. Now we've got the frame built but we've stalled out at the axles. They think we could just get away with welding 4 bolts to the SIDES of the frame and mounting tires to that. From what I've read and seen most guys do a full axle of 3/4" round bar and weld it to the bottom of the frame and mount tires with washers and cotter pins. Could use the advice of anyone who's made one and done something other than the bar on the bottom of the frame? Thanks.
