A Look at the Proxxon Motorized Angle Polisher
Last issue, I wrote about Adam Savage restoring the yellowed plastic cover of a vintage Nagra IV-S audio recorder. He ended up using a combination of a 12% hydrogen-peroxide bath and stages of a polishing compound to bring the cover back to its former glory. In this video, he talks about the Proxxon motorized angle polisher he uses while restoring the faded and scratched plastic dome on a spacesuit helmet replica and extolling the virtues of the tool.
Paint Coatings: The Great Weapon Against Rust
Grady of the fantastic Practical Engineering channel continues his series on corrosion engineering by looking at one of the great weapons wielded in the war against steel rust: paint (or more accurately paint coatings).
Next-Level Oscillating Multi-Tool Tips
Wow. James of Stumpy Nubs always brings the goods, but I learned so much from this video on improving one’s use of an oscillating multi-tool. I just recently bought my first cheap oscillating tool (to see how I like it) and am just beginning to learn how to use it properly. Even if you’ve had an oscillating tool for a while, I bet you’ll learn something here. How to angle your plunge cuts, pre-scoring cuts, holding onto the blade for better control (yes, it’s safe), using semi-circular blades for making straighter lines, so much more. Lots of tips for cutting metal with an oscillator, too. And, James has a good recommendation for an inexpensive blade assortment.
Quick ‘N Dirty Aluminum Casting
In this Daniel LupienYouTube short, he shows you how easy it is to create a simple sand mold and cast it in aluminum. All you basically need is a chunk of aluminum, a crucible and tongs, a source of heat, some kinetic sand (or regular casting sand), and something to press into the sand to create the mold.
No-Cost Stud Finder
When my wife and I moved to our new digs in Benicia, CA last fall, I needed to install a swivel-arm wall mount for our TV. I simply used a 1″ disk magnet I had on-hand to locate the stud. No fancy stud finder needed. In this Becky Stern tip, she shows the method of using a string and a magnet. Easy peasy. If you’re uncomfortable with this method and want to make sure to find the center of the stud and locate (and steer clear of) any wire runs, pipes, etc., sophisticated imaging scanners can be had for under $30.
Fixing a Leaky Faucet with a Ten Dollar Tool
We know that professional plumbing doesn’t come cheap. Doing your own basic maintenance and repairs may seem intimidating, but it shouldn’t. Jobs like clearing a trap, changing a toilet float assembly, or replacing faucet washers are relatively simple and easy. Years ago, I changed a toilet float kit. It was easy (after getting the very frozen-in old assembly out). And, I felt like I’d accomplished something and saved myself over $100. The replacement kit was $15.
Mark Frauenfelder of Cool Tools recently replaced the rubber washer in his shower. He writes in Recomendo: “Our shower head was leaking, even after I replaced the rubber washer. YouTube informed me that I had a scarred valve seat, which is the brass ring that’s supposed to form a tight seal against the washer. I bought a reseating tool for about $10 on Amazon, which smooths the surface of the valve seat. It worked, and saved me a $150 plumber visit.”

Shop Talk
Reader Art Elliott shares this tip:
“My fav pencil is the tri-conderoga. It’s the best of both worlds. Three sided, so it doesn’t roll away, and thinner than a regular carpenters pencil, so you get sharper lines, but it’s also thicker than a regular pencil, so the lines are still nice and thick. My family got me a pack for Father’s Day and they’re my go-to in the garage.”

On the issue of CA glue curing accelerated by water or baking soda or baking soda and water, reader Josh Martin writes:
“Setting CA glue with water makes an inconsistent, often crumbly consistency to the set glue. Baking soda improves on this, but nothing works as well as accelerator (or just time).”
In reference to storing CA glue in the freezer, reader KX4WD enthuses:
“The money I could have saved on super glues over the years with this storage tip!”

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.
I created a searchable archive of every product we've recommended in Recomendo and our other newsletters since 2020. The database includes thousands of items (with photos) that you can filter by category, date, or keyword. Want to see all the knives we've reviewed? Just type "knife" in the search field. This makes it easy to browse our entire review history or find specific recommendations. The site is ready to explore, though I'm open to suggestions for improvements. — MF
Imagery playground
I still regularly create AI imagery of my dreams using Midjourney, and I recently discovered Whisk, a Google lab tool for blending different visual elements into something entirely new. I just drag and drop the images, and I’m able to merge styles, subjects, and scenes. I can provide some visual guidance with text, but you don’t need to be an expert at writing prompts to have fun with it. It feels like a playground for creative visualization. — CD
Unforgettable experience
Like the Grand Canyon, or the Pyramids, I believe Burning Man is something you should experience at least once in your life, no matter who you are. This year is a good time to go, because it is no longer cool and you can easily get tickets. It is still a spectacle of art and creativity, a wonder of urban design, a singular example of a miraculous gift economy, and the best bicycle city on Earth. The cliches about it are all true, yet it will astonish you. I will make this guarantee: If you have never been to Burning Man, and you go this year and are bored, I will personally refund your ticket price. The festival erupts north of Reno, Nevada from August 24 to September 1, 2025 and the easiest way to attend it is in an RV. — KK
Clever Word Game: Bracket City
I discovered a delightful five-minute word puzzle game called Bracket City. The gameplay is simple — you just start typing words to solve crossword-like clues in brackets that are nested within other clues. What makes it addictive is how the clues build on each other, with each solution revealing new parts of connected puzzles. Here's the tutorial example: [where [opposite of clean] dishes pile up] or [exercise in a [game played with a cue ball]]. You can peek at the first letter of any clue if you're stuck. I’ll bet the NY Times will end up buying it. — MF
Top-rated things to do
Things.in is useful for creating a travel guide and a curated list of the top sights, restaurants, and places to stay in a city. I’m currently planning a trip to London and feeling overwhelmed by all the history and important sights to see. This tool is helpful in narrowing down my itinerary. — CD
Electrician’s magic wand
I noticed several professional electricians using this thing: The Klein Non-Contact Voltage Tester is a small magic wand that beeps when it detects a live current in a wire, or a switch or a cable or anything electronic. The cool thing is that you don’t need to bare the wire or contact, you just wave this near the wire. That is both much safer and way quicker. It can detect voltages between 12 and 1,000 which will be enough for most uses. For me it has replaced several devices in my toolbox I used to use to detect a live current. — KK
