Reference Cards

Here are some pretty reference cards I made a while back:

  • Scale Landmarks: What's something you're familiar with that is about 10 nm big? How do the speed of continental drift, a raindrop, a champion sprinter and an SR-71A Blackbird compare? What is the range between the least massive (electron) and most massive (universe) objects science can describe?
  • Periodic Table
  • Periodic Table, Flat -- material properties as a table and not as Mendeleev puts it.
  • Mechanical, Geometric and Material properties of Screws, Bolts and Fasteners - probably the most useful among these, this gives thread geometry, decimal inch/screw/metric equivalents, mechanical strengths, torque ratings and more. Super handy for machining or general shop use.
  • A similar table for AN Hardware (milspec fasteners used in airplanes, racecars and hot rods).
  • A flat table of decimal equivalents: decimal and fractional inch, metric, and standard (US) screw sizes.
  • ASCII Chart - easily index up hex, octal, ascii, symbol font/latin font/DOS font values for characters.

Old-School Shop Guide

I rediscovered this super-compact reference-and-tool-and-measuring device while looking for a tool. It is jam-packed with handy information for anyone doing things mechanical or woodworking. I got this from a family friend of a family friend -- I bought their lathe after her husband, an avid (and skilled) woodworker, had passed away. She wanted his tools to go to someone who would love them and use them, which was me, which I do. The lathe is good, but I've discovered after the fact that the throwins were the best part. The chisels are *top notch*, but still pale in comparison to getting "his old woodworking magazines." This turned out to be almost every issue of Fine Woodworking magazine, beginning in its first year of publication; somewhere in the stack was this nifty Shop Guide.
I think this thing is so neat -- so much information in such a small space. My own mechanical data reference table (more here) has more numbers but less intrinsic functionality ... What's really neat about this shop guide is how they used the shape of the guide itself as a tool. Print this onto heavy cardstock and punch brother punch with care... enjoy!
