I wish I could find the CD with the drawings of the "Rubin" job. 17" by 22" as required by local building code. I only have the drawings. Magnificent work, but they won't fit on my scanner.
Lots of old memories here. A can of powdered eraser particles that could be used to "float" the triangles, several hardnesses of pencils (6H to 2B) to make lines from, "You will never see them on the finished product" to, "Bold, strong outlines" of the whole page. A block of wood with 600 wet&dry sand paper to get your point correct.
The thing about vellum is that you can erase a line a dozen times and the vellum will never show any wear. The trick was to never make a dent in the vellum by using the wrong pencil and pressing harder. It would seem to be a lost art by now, like setting lead type, but those were taught in schools in the 1950's and 1960's. I did set type, I did do basic sheet metal joints, and I did do mechanical drawings. One of those skills still has a purpose.
I finally got a PDF of part of page. It doesn't look very good after the scanning.
The county clerk that was in charge of being a jerk demanded a separate page showing all of the non-existent penetrations that we didn't make between the first and second floor of the building. I carefully made a floor plan of the first floor, then a copy of the exact same page labeled, "Penetrations marked on this page". He tried to puff me up with heaps of praise for doing such good drawings, for a lowly air conditioning contractor. I just got out of the building before he found out the third page was an exact copy of the second page.
