Just grab parts from a wheelchair lift some skoolie is scrapping to make the lookout tower lift. Add some dry ice for a smoke effect and a hold up a Braveheart sword as your throne, er chair rises up through the opening, and you can really make a really royal theatrical entrance.
Though as a ham radio operator, a "lid on the roof" evokes a totally different meaning to me.
[Explanation: while the published definition of "lid" is a radio operator with poor on-air practices, it can loosely be used to describe any person who behaves like their elevator doesn't go all the way to the penthouse.]
Anyway, good progress.
I know I couldn't keep up with you.
