I'm in the middle of service calls and stopped home for lunch and decided to pull out a fun book to read. I bought this many years ago on eBay for like $5. This is a text book for the Carnegie Mellon school of technical trades in Pittsburgh PA. It's dated 1908. I bought a bunch of these books because I just felt they were worth owning and enjoyable to read and learn. This is book 1and it takes you through a series of lessons starting with sharpening a pencil, to drawing lines, to drawing a square, then a bolt, then letters, all the way to complex drawings like the tailstock on a lathe. It's a lost art these days. Anyone here old enough to remember drawing by hand like this prior to CAD? There's something really neat about hand drawings that really pull me in. I can't be the only one who likes this? Older scratch built airplane planes can be pretty fun to look at just for this very reason, the art, the uniqueness of it. Hopefully the few photos I took of the book show up for clarity.
