Since we posted the collector article with mention of slide rules a few of you have asked where you can find out more and if we’ll have an article in MAKE, well – we do!

Pictured here, the Nuclear bomb effects calculator (1962) and the Bristol Liquids SynchroValve Capity Calculator (1943) from Calculate This! by Robert Luhn. MAKE looks at slide rules. Info and article, page 50.

  1. this would be even cooler if the shells were already used. collecting spent shotgun shells would be a challenge, though.

  2. I’m going to the old shooting range with a rake in spring to collect some spent casings, this is a neat idea.

    I know some gun collectors, maybe i’ll make a display rack out of shells.

  3. awwww.. they are empty! its much more frightening if they were all loaded.. (yes i know how very hard it is to accidentally set off a primer.. but still.. i could imagine being a little twitchy flopping down in the Chair of Damocles

  4. As someone who shoots and makes art in NYC (and I know I am not the only one), I need to clarify:
    The number “12” is not a caliber but a gauge which, in it’s antiquated denotation, is the number of spheres that make up a pound of lead that fit a certain diameter barrel. Change that “.12” to a “12.” There are a lot of examples of 12-gauge art/furniture/etc. Personally, I like the 12-gauge Winchester shot glasses.

  5. My sone often target practices with a variety of guns. Feel the spent shells are such a waste.

    Need patterns to make items out of spent shells to sell at craft fairs.

    any ideas out there? willing to pay for patterns, instructions but need a picture because i am a visual person.
