A Little Nut Magic

From Machinist's Workshop: "When I find it difficult to place a ferrous fastener in an awkward position or in tight quarters, I slip a small, flat (3/4" diameter x 1/8") neodymium magnet into the index finger of a thin mechanic's glove. When I put on the glove, I place the pad of my finger on the magnet. Now, the fastener will stick to the glove because of the magnet inside and I can position it where needed." [H/t Sean Ragan]

A Thread-Tapping Master Class

In a recent Tested "One Day Build," Adam Savage conducts a 40-minute master class on thread tapping, culminating in a project to build your own thread tapping guide from a chunk of acrylic. Lots of great stuff here, with tips and tool recommendations, such as Adam's favorite tap set, tap wrench, and tapping fluid. [Via Maker Update]

Great Intro to Calipers

Hacker, engineer, Kyle Cothern has a most excellent introduction to analog and digital calipers. This essential precision measuring tool is intimidating to many makers. It shouldn't be. This article should help demystify them, how they work, and why they're so useful. It has some things in it I wasn't even aware of, like various accessories you can get, such as a base attachment to hold calipers perpendicular to a flat surface when taking depth measurements. The one thing I don't agree with is the recommendations on which calps to get. I don't think you need to spend hundreds on a decent set of digital calipers (for most users). I'll continue to swear by my under-$42 iGaging set. [Via Joshua Shachter’s Wheelhouse]

Maker Slang

Jargon, slang, and technical terms for DIYers.

Blind hole - A hole that doesn't penetrate the material all the way through. As opposed to a through hole which does go through.

Feel - The secret sauce of working the physical sciences. This is knowing things like how much force, pressure, tension, torque, etc. you can safely apply to a given object. This is largely a learned skill.

WDITOT -"Why Didn't I Think Of That." Not to be confused with ID10T, which is another thing entirely. [via Steve Roberts]

Welding boogers - Bad, ugly welds or a weld blob that has adhered someplace where you don't want it.

Heat-Shrink Earbud Plug Adapter

I got tired of hunting for/misplacing the Lightning-to-Mini Jack adapter for my Apple earbuds. So, I used some heat-shrink tubing to attach the adapter to the mini-jack cable.

Fixing LCD Screens

Reader John Ü shared this with me: "You can rescue even a badly scratched LCD screen on a resin 3D printer with a 3M headlight polishing kit. Found this out the hard way this week."
