[SML] Detailed drawings for man-powered stage lift

[Joe D]

I am seeking some detail drawings for a trap lift.  Specifically, the kind that use cables and wench to do the lifting. I have seen overall concept drawings in books, but never detailed drawings. I realize there are an infinite variety of widths, and heights, but those are easily adjusted.  Can anyone recommend a source for a set of detailed drawings that I can send to a fabrication shop?
