Let me try to understand this whole thing, (1) I check on hide from render then set a key frame for x-amount of frames (2) check hide from render at the end of the amount of time that I want it to be hidden (3) uncheck hide  from renderand add a key frame at the start of the new sequence?
This didn't work the object was still visible after I rendered it.
Is hide from render the only way to accomplish this?
