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.
You razor-cut things on this mat, and unlike other materials it won’t accumulate a field of cut marks to misguide your blade. The self-healing rubber keeps the surface uniformly smooth, clean, and firm. And protects your table. Get the largest one you have room for and can afford. A large mat also says: don’t pile stuff here. — KK
Until a couple of years ago I had struggled with different inexpensive paper cutters, but I kept finding myself going to Kinko’s and using the cutters there. Then I got smart and jotted down the brand name, Dahle 550 Rolling Trimmer Paper Cutter, and bought one online.
What I appreciate most about this cutter is that I never have to change blades, or deal with dull blades, because it’s self-sharpening. The steel rotary blade contained within the plastic safety housing moves across a stationary blade that extends the length of the cutting platform. This action hones the rotary blade, which remains constantly sharp. It’s also set up for wall mounting, which is ideal in my home office layout.
One of the Dahle’s downsides is that the plastic plate that holds the paper down got dinged up — keep away from kids — causing the blade to run off the track if I’m not careful. Also, the next one I buy will be a larger model: The 550 is meant to cut up to 14 1/8-inch paper, but it’s awkward cutting anything over 8×10. — Andrew Heidrich
Rotary cutters aren’t new tools. It’s just taken me awhile to appreciate how great they are. The Fiskars Rotary Cutter replaces exactos for most heavy-duty cutting jobs in our household. It’s faster, surer, easier and therefore safer to use than razor blades. It will slice through paper, vinyl, cardboard, fabric, and foam board with ease and accuracy. I can only manage perfectly straight long cuts with a rotary cutter and straight edge. Cutting curves is buttery. Seamstresses can add pinking blades. The replaceable blade retracts when not in use; it can be side-switched for left-handers. When I think “cut” I reach for this tool. — KK
It is simply impossible to make a genuine straight, right-angle cut on paper using scissors, or even a razor blade and straight edge. The old guillotine paper cutter could deliver a clean cut, but at the risk of taking your fingers away. Fiskars, the scissors makers, invented a cutter with a tiny blade mounted on a hinged holder that zips through paper without any possible harm, even to the youngest children. It’s fast, accurate, and crisp. — KK
A classic bone folder is made of real bone, not plastic or Teflon, and resembles a fat, blunt-edged tongue depressor, rounded at one end and pointed at the other. With it, I can turn a digital print, piece of cardstock or watercolor paper into a professional-looking note or greeting card.
Pulling the pointed end alongside a straight edge and across the paper produces a subtle score that facilitates a perfect fold. Next, I fold the card very gently by hand along the score, and then stroke one of the short, straight sides of the bone folder along the score to flatten the rounded fold to a sharp crease.
When sending a letter that I want to look good, I make two quick strokes of the folder along preliminary hand folds to create folded edges that are sharp and square. Bone folders also can be used to burnish paper as it is glued to cardstock, album or scrapbook pages. They produce accurate and sharp folds and creases on origami papers as well as facilitate sculpting, architectural modeling or bookbinding with paper.
I recommend rubbing your bone folder with olive oil from time to time to avoid flaking or brittleness. Folders made of real bone are best, unless you wish to use a Teflon folder to avoid the slight luster sometimes created by the friction of a real bone folder. — Clifford Peterson
I like to clip items from the newspaper or magazines that are relevant to my clients and prospects. This tool makes that task simple — just grip between thumb and forefinger and trace the outline of the article you want to clip — you even leave the underlying pages intact! — Bruce Bradford
Two rotating wheels slice paper the way an open scissors does occasionally. Absolutely marvelous for cutting wrapping paper or making lots of long cuts. Also great for kids who don’t quite have the coordination to use scissors well. We keep ours in the gift wrap box. — KK
