Have any of you put together movable gantries like we saw with the rockets from the 50's & 60's? I have built some gantries, but I'm using pistons, set as large as possible, to move my gantries. I have been using hinge rotators to open and close the gantry doors, which are made from the flat panels. Lately, I've been using the cargo bays as part of my gantry.
