I got a phenomenal response to my request for input on this newsletter. Thanks to all who messaged me. Turns out, an overwhelming number of you like the newsletter the way it is and simply offered encouragement. I also got several excellent suggestions for new features which I’ll be rolling out in the coming weeks. Keep those cards and letters coming!
How to Restore Yellowed Clear Plastic
In this quick Tested video, Adam Savage sets out to restore the lid of a gorgeous vintage Nagra IV-S audio recorder he recently acquired. The machine is in surprisingly good condition, but the clear plastic cover was scratched and badly yellowed. Doing research, he found many recommendations for using 12% hydrogen peroxide. He tried it with partial success. He discovered that finishing it up with plastic polishing compound returned it to something close it is original glory.
Making a Cheap, Simple Air Cleaner for a Small Shop
In this I Build It video, John shows how he made a simple and inexpensive air cleaner for his small woodshop. The air cleaner was made from little more than a small fan, a piece of duct piping, some scrap ply, and a several shop vac air filters. I love the way it can be expanded (with additional filters) via a threaded rod that holds the filters in place.
IKEA Wrenches on Your Pegboard
I just discovered a use for all of those hex wrenches that come with IKEA and other flat-pack furniture. They make perfect pegboard pegs!
Oil Can!
The tin man in dire need of maintenance.
The other day, while oiling a squeaky hinge with some lithium grease, I flashed on my granddad. A consummate tinkerer and inventor, Gramps was obsessed with maintenance. He frequently had his spring-bottom oiler in hand, blue shop rag tangling from his back pocket, going around the house, the yard, his backyard workshop, the car, lovingly maintaining the machinery of his life. I decided in that moment to try and be better at doing the same. Moments later, on Twitter, I saw this Kurt Vonnegut quote: “Another flaw in the human character is that everybody wants to build and nobody wants to do maintenance.” Exactly. OIL CAN!
Maker Slang
Slang, jargon, and technical terms for the realms of making things.
Crown pulley – A pulley designwhere the center has a larger diameter than the outer edges, thus a “crown.” Perhaps counter-intuitively, the belt on the pulley will always seek the area of highest tension, returning it to the crown. Via Maker Update.
Promptcrafting – In AI art, it’s all about the quality of the prompts you craft. The better your invocation, the better the magic that gets returned.
Rewilding your attention – Writer Clive Thompson has been promoting the creative benefits of exposing yourself to the novel, the offbeat, the serendipitous. Look beyond what the online algorithms feed you – rewild your attention!
Shop Talk
As stated in the intro, I received many fabulous emails from you, dear readers. Here is one from Paul Cryan. Look for some tips from Paul in a coming issue!
“Thanks for doing all you do. Your tip books [Ed: Vol 1, Vol 2.] are great and I’m really enjoying the newsletter. I bought and devoured both of your books, in Kindle and PDF formats. I refer to them often and having the search function (via either the Kindle app or iBooks, respectively) is really handy. Every few days, I find myself looking at objects in new ways and going back to your references. This past Friday, I didn’t have a clamp within getting-up-from-my-chair distance at my office desk, so I ended up using a pair of pliers and a rubber band to hold together a plastic part I was gluing. Thanks for putting that seed in my head.
“The only problem I have with the weekly newsletter is that it gives me way too many things to think about and try per unit of time!
“With your tips books, I’ve got months to read through them and try things out. This week, I experimented with the lanolin mineral oil mixture to rustproof tools out of your latest tips book and it seems to hold much more promise than Johnson’s Paste Wax for keeping my old restored Shopsmiths looking and working great. I still need to test whether the stickiness can be buffed sufficiently off the power-tool surfaces to avoid particles grabbing, but so far so good. And who doesn’t like that faint smell of ungulates on their metal? 😉
“With the newsletter, I’m interested in just about everything you cover, which leads me to a weekly frenzy of investigation and implementation. Within the past month I’ve upgraded our broken sink strainers to the OXO type (love them), picked up a Williams ratcheting screwdriver (my new favorite ‘good enough’ tool), and bought Fat Boy pencils and FastCap markers that have me wondering how I didn’t know about these things before. And now I’m browsing saw blades!”

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.
MyTaxReceipt shows you a breakdown of how your U.S. federal taxes get spent — enter your Zip code and the amount you paid in Federal taxes (or you can use the default average for your Zip code). It generates a receipt-style summary showing what portion goes to defense, healthcare, interest on debt, and dozens of other categories. It’s eye-opening to see actual dollar amounts. The site also lets you message Congress about your spending priorities with one click. — MF
Digital passport
You can add a US passport as your digital ID to your wallet app on an iPhone running iOS 26.1 or later. You still need to carry your passport overseas, but you can pull out this ID for TSA clearance at 250 airports in the U.S., including SFO, LAX, JFK and LGA. To do this go to your wallet, hit the + in the upper right, then choose “Driver’s License and ID Cards,” then “Digital ID.” You’ll be prompted to hold your phone’s camera over the photo page of your passport and then you need to touch your phone to the chip embedded in the back of the passport. Then you’ll be asked to take a selfie and do some prescribed head movements to verify you are real. Finally, your application will await verification. Once verified (mine took only a few minutes) your passport ID will appear in your wallet. — KK
2025 photo dump
Two tabs worth opening up in full screen are TIME’s Top 100 Photos of 2025 and BBC Science Focus’s 31 jaw-dropping space photos. The first depicts the past year’s major cultural moments — like political conflicts and climate disasters — and everyday life on a human scale, and the second is a gallery of cosmic wonders, catapulting you out to a higher perspective. Both snapshots of existence feel equally important to witness. — CD
Sweet Korean dramas
I am not a Korean drama aficionado, but my wife is a big fan, and she has persuaded me to watch some of the better ones. When folks who have never seen a K-drama ask where to start, I suggest they watch any of the following three series. All three are exactly the same story: They are all rom-coms set in a modern workplace, with protagonists using multiple crossed identities, love straddling class lines between boss and employee, and convoluted plots that tie everyone together into one story. (There are no coincidences in this world.) In order of ease of access: 1) Business Proposal, 2) Start-Up, 3) Would You Marry Me? — KK
Quickly find all purchases in Gmail
If you want a quick way to see all your receipts in Gmail, I recently noticed that in my personal account a “Purchases” label category was automatically created and added to my sidebar. Unfortunately, this feature is not available in my Google Workspace account. I use both personal and work emails for shopping, so to mimic that view I type “category:purchases” into the search box to display messages that include receipts, purchase confirmations, invoices, and statements. This is especially helpful during the holiday season. — CD
Giant roll of craft paper
I recently spent time with friends who mounted a 36-inch by 200-foot kraft paper roll with a steel dispenser and cutter at the end of their work table. It’s surprisingly useful. Pull out a few feet for messy art projects, cover a table for a party, or tear off sheets for gift wrapping. The cutter gives clean tears across the full width. — MF
