Redpower Frame Motors

[Silent_Potato]

So, i just got into the Redpower mod and i have been experimenting with the Frame Motor. Now, i want to make a type of Elevator for it, but unfortunately, i need some kind of block that WON'T be moved by the Frame Motor and can be retrieved legitimately. Is there ANY block/item that it absolutely won't move? (Do not say Redpower machines, i don't wanna fill in areas with that.)

When you set up the frames that attach to the frame motor, I'm pretty sure that frames to which you attach covers (of any type) will not allow adjacent blocks to be moved. So all you have to do is build an elevator of frames and attach covers of the type you prefer (I like obsidian).
