Lineage and the Nobility of a Trade
My dad passed away on June 14th at the age of 90. He was a civil engineer and a building contractor. He was an engineer in the Air Force during the Korean War, building runways. His father, my granddad, was a talented jack-of-all-trades and a clever, whimsical inventor (he made himself a pair of convertible pants and a shirt several decades before the concept was patented). They both instilled in me, from the earliest age, the do-it-yourself ethos. When I was 5, I almost electrocuted myself when I tried to take the kitchen toaster apart with my Handy Andy tool set to find out how it worked – while it was still plugged in!
Here’s something I wrote in my first Tips book (which was dedicated to dad and granddad) about watching my dad seemingly effortlessly build things when I was a kid:
One of my early memories was being with my dad while he worked. I remember riding in a Gradall Excavator with him when I was a wee one. I thought my dad was basically the coolest guy on Earth because he could confidently pilot such an impressive, intimidating machine. As a pre-teen, I remember watching him swing a hammer while he was adding some rooms to the basement of our home (which he’d also built) and realizing how regular and perfect he was with his swing. It usually took him the same number of strikes each time to drive and countersink a nail – one swing to set the nail, one to drive it most of the way in, and a final whack to counter-sink it. I don’t remember exactly how old I was, but it was probably the first time that I instinctively understood the nobility (and the efficiency) of perfecting a trade. If you do something enough, you get impressively good at it.
Tools are an extension of our bodies, our intentions. Like specialized “end effectors” on a robot, they instantly give us special abilities; superpowers. Combine the right tools, the right materials, and the proper know-how, and human beings create worlds. Tools are the physical interface between our dreams, our imagination, and their real-world realization. But our tools are not only powerful extensions of ourselves, they also contain stories (see above).
My dad (and my granddad) taught me about both the power of tools and the power of storytelling. Little did they, or I, know when I was growing up that my job would end up combining these two powers.
Knurled Knob Generator
Who doesn’t love a handsome and grippy knurled knob? This OpenSCAD script on Thingiverse allows you to generate knurled knobs of various sizes that slide over bolt heads. The script requires the OpenSCAD compiler to generate the 3D models.
Using Syringes to Clean Out 3DP Resin Vats
Back in January, I wrote about Daniel Herrero‘s “hack” of using a peristaltic pump to clean out his resin vat for his 3D printer. And then, based on comments to his post, he got a better idea: using large syringes to suck out the remaining resin. He experimented and determined that a 150ml syringe works best. Once again, YouTube comments to the rescue. He complains in the video about the hard plastic syringe head scratching his FEP film at the bottom of his vat. Commenters suggested adding a short bit of rubber tubing to the tip of the syringe. He also mentions the resin scraper that comes with printers scratching his FEP and viewers remind him that a silicone plastic spatula (I got mine from the dollar store) won’t scratch the film.
Do Different Formulations of Motor Oil from the Same Brand Really Behave Differently?
Todd at Project Farmwanted to know if different formulations of oil from the same brand (Penzoil) perform differently, and is the high-end oil all that different from the cheapest one? The formulations tested were Pennzoil Synthetic Blend, Full Synthetic, Platinum, and Ultra Platinum. He sent the oils out to a lab for analysis and also tested them for evaporative loss, lubricity or film strength, and cold oil flow both new oil and after exposure to heat. Additionally, in a final test, Pennzoil Ultra Platinum was exposed to 10% gasoline and another sample to antifreeze to test the impact it had on lubricity and oil performance. Bottom line? This looks like a “you get what you pay for” result. The most expensive of the lot, Ultra Platinum ($28 on Amazon at time of test, $14.22 currently), definitely performed the best. That’s actually lower in price than the cheapest one at time of testing (Synthetic Blend, at $17). And, if you buy 6 quarts on Amazon, the Ultra Platinum blend is only $8.60/qt.
Fantastic Free Class for Learning Arduino
Via the always-informative Maker Update comes word of this really wonderful series of beginner educational videos on the hardware, development environment, and code used for the ubiquitous Arduino microcontroller. If you’re interested in getting into Arduino, there is no better gateway.
TOYS! Liquid Chrome Markers
I recently saw Adam Savage use these chrome markers in a video where he was weathering a prop that he’d built (the motion tracker from Aliens). I immediately bought a set and man do I love them. If you have a need to faux chrome anything…
FrogPod is Now on Kickstarter
I’ve been a big fan of Thomas Baisch‘s Instagram page, InfiniteCraftsman, for a while now. He posts one innovative shop solution after another, most of them 3D printed. One of his most brilliant creations is the FrogPod, a flexible, magnetized three-legged camera mount that you can slap onto metal surfaces. He recently launched a Kickstarter to raise an army of FrogPod users.

Cool tools really work.
A cool tool can be any book, gadget, software, video, map, hardware, material, or website that is tried and true. All reviews on this site are written by readers who have actually used the tool and others like it. Items can be either old or new as long as they are wonderful. We post things we like and ignore the rest. Suggestions for tools much better than what is recommended here are always wanted.
What are the different parts of a knife called? How about the parts of a plough? Does anyone know what kind of mousetrap this is? What do Eskimo ice scrapers look like? I’ve got this chrysalis here — what kind of butterfly or moth will emerge from it? Can anyone show me the difference between a bath tap and a double flexible tube cock? How about a White Persian versus a Manx? How did the piano evolve? What kind of ship is that sailing out of the harbor?
All of these questions and a ridiculously large number more are answered in Mann’s Pictoral Dictionary and Cyclopedia, 240 pages of the most miscellaneous miscellany out there. Each page poses a not-entirely-naturally-worded question at the top, then answers it with illustrations. If we believe the foreword of this 1960 edition, the original book was found in a bombed-out library in England shortly after WWII. One illustration shows a woman’s hairstyle from 1920, while another list, “To Which Country in the British Empire Does That Badge Belong?” includes Kenya and Gold Cost which, if I know my British history (note: I do not), suggests the book was published sometime between 1920-1957.
I’d owned this book for several years before I realized that the pages are not random, they’re alphabetical (as long as you can figure out what category the page has been classified under, which is not always clear). This leads to delightful transitions like going from cat’s cradle games, to cattle breeds, to oak chairs, or from “What Bible Fruit is That?” to “Examples of British Game Birds.”
The British dial is set to 11. “What is the Name of That Sedge? The Chief Species Growing in Britain” is a two-page spread on grasses. “What is the Meaning of Those Badges Worn by the Boy Scouts?” asks another page. “Which British Owl is That?” — it turns out that “Ten owls are found wild in England, and by means of these drawings it will be possible to identify any owl that may be seen.” Identify your raptors with confidence, Britain! It’s out of print, but used copies can be found at the link above. – Sara Lorimer
DEATH IS STUPID TALKS STRAIGHT TO KIDS ABOUT A TOPIC MOST GROWN-UPS STRUGGLE WITH
Death is Stupid by Anastasia Higginbotham The Feminist Press at CUNY 2016, 64 pages, 8.5 x 8.6 x 0.5 inches
Death is Stupid does what so many grown-ups struggle to do with their kids. It tells them the truth that they already know. In collages of illustrations and dialogue, Anastasia Higginbotham walks readers through the confusion and questions that come when someone dies. Using two concurrent narratives, one that broadly voices and validates the feelings and fears kids have around death, the other focusing on a little boy whose grandmother has died, Higginbotham masterfully draws connections for young audiences and their grown-ups.
The story opens, gracefully straight-forward, “When a loved one dies people can say some stupid things.” The line stretches over the course of three pages in which the boy goes from surprised to sad as he hears, “I know exactly how you feel.“ “Don’t cry.” “Just be grateful for the time you had with her.” We follow him through the funeral and days after, through the rituals of grief and remembrance, through the fumbling adult attempts to explain and comfort. Through his experience and the narrator’s staccato interjections (“Dying is not a punishment. But it mostly doesn’t feel fair.”), readers are given the space to explore the well-intentioned answers and advice that grown-ups pat into the palms and shoulders of the kids they love, and the ways in which those hugs and kisses can land like blows.
Just as the boy tries out different ways to stay connected to his grandma while accepting her death, like caring for her garden, readers can explore suggested activities at the back of the book. Higginbotham offers templates for personalized remembering of both pets and people, simple instructions (“Read what they read. Make what they made.”), and the loveliest reflection on the power of speaking someone’s name. I know that when we are inevitably grieving a loved one’s death, I will be grateful to have this book on hand to read with my daughter. – Mk Smith Despres
