T4 and explained about 1000 times we didn't have nearly enough bricks for a
T2 to hold it, we settled on an elevator car with an accordion style lifting
mechanism. I ended up using pneumatics (and a reciprocating 2-large cylinder
pump, springs removed) but I would have loved to have the platform go up and
down with a screw mechanism. Now, maybe it would have required grease, but I
can think of a lot of other lower stress uses as well.
