Crossmember idea..... here\'s mine Hey kiddies, Due to the way I mounted my sliders (see 2nd pic.) I needed to build an additional crossmember to help the whimpy frame out. Any load on the sliders would cause the frame to tweak outward. I built this to tie the two together and it seems to have done the trick. Lemme know if you think it sucks, I wont mind.
