Havent come across any more slide rules lately but everywhere I turn there are the boxed drafting sets. Used to open the cases to see how complete they are, all that chrome, and graphite dust. I turned down mechanical drawing in high school as I had that teacher previously and had little confidence in his abilities and no respect for him as a person. MIght just buy a set yet, even though at most I build things by rule of thumb and TLAR, (that looks about right). Anyone get into mechanical drawing/drafting ?
