I'm wondering how much stability is in these drawer giudes? There may be some up and down movement due to manufacturing tolerances, but will have to see what happens when it is all put together. Good idea for a full extension bed assembly. A "friction lock" meaning a system cam of some sort? What is your target for overall weight of this camera? tim

P.S. "Im envious of all you handy gents and your camera building..." Geez Matt, you are too modest!
