I'm working on an art display system and would like to emulate the mechanics used in the old chalkboards ... where one framed slate panel could be raised/lowered revealing a panel behind.
Unfortunatly, these kinds of chalkboards arent' made anymore and I can't find any resources that sell them (even on EBay!). But, I would like to find out how the mechanics work.
Do you think they worked like old windows?
Hmmm ... Stumped.
