Nice work, did you this fashion this off of the Oxford dump bed? Looks just like it.

not much new to post, bit frustrated. been working on lift system, based on a screw drive type setup, with a sliding block between two rails with a rod attached to it and the box. I tried pushing and pulling on the block. but the box will not lift, it just binds up, feels like it wants to rip the box off, unless I lift the box up a inch and it goes up no problem, can't figure out what the problem is?

If your mounting point on the slider block and the dump box are on the same plane or level you are right it would never lift. You'll have to pick a spot on the slider that is as low as you can mount the push rod. The same goes for the dump box mount. Try to get mount as close as posible to the floor of the box, maybe even build up the box frame. That way it won't try to push strait out, but will have some angle for leverage to start the lift.
