I don’t recall sketching charts as difficult so much as tedious. Same an any task that requires memorization. Of course being tedious makes it difficult as you have to stay at it for long periods of time.

Here is part of Stephens Passage chart 17300. It is difficult for me to do a neat drawing.

I use an outfit “Alphagraphics” in Lynnwood, WA. Same type of deal - engineering blue prints. About $50 for lets say 6 chartlets and 4 copies of each. Get a disk copy too.
