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.
Steve Martin recounts his 18-year journey from an amateur magician to a comedy superstar. It’s filled with invaluable insights into the creative process and the price of fame.
Core Principles
Embrace Originality Through Elimination
Martin discovered that true comedy innovation came from removing rather than adding elements. He systematically eliminated punch lines, traditional setups, and familiar comedy structures, creating tension without release. This approach forced audiences to find their own moments to laugh, making the experience more personal and memorable. The principle applies beyond comedy — breakthrough innovation often requires abandoning conventional approaches entirely.
Precision Creates Movement
Every gesture, pause, and word must serve the performance. Martin learned that comedy required the same attention to detail as classical music or dance, where timing and physical expression were as crucial as the words themselves. He developed a philosophy that "precision was moving the plot forward, was filling every moment with content, was keeping the audience engaged."
Consistent Practice Over Natural Talent
Martin openly admits he ”was not naturally talented — I didn’t sing, dance, or act — though working around that minor detail made me inventive.” He performed thousands of shows, often multiple times per night, refining his act through direct audience feedback. His success came from treating every performance as both a show and a learning opportunity, constantly adjusting and improving based on real-world results.
Know When to Walk Away
At the height of his stand-up success, performing for arena crowds of 20,000 people or more, Martin recognized that his art form had reached its natural conclusion. He walked away from lucrative contracts and massive audiences because he understood that continuing would only diminish, rather than enhance, his artistic legacy. This principle of strategic abandonment requires courage but often leads to greater creative fulfillment.
Try It Now
Record yourself practicing your craft for one week, then review the recordings to identify patterns and areas for improvement — just as Martin used cassette recordings to refine his performances.
Eliminate one conventional element from your creative work and observe how the absence forces new solutions or approaches.
Set a specific practice schedule and track your hours, treating consistency as more important than natural ability or inspiration.
Identify one project or commitment you should abandon to make room for higher-potential opportunities, even if the current situation feels comfortable or profitable.
Write down your definition of success for your current creative endeavor, including the criteria that would signal it's time to move on to something new.
Quotes
"I was seeking comic originality, and fame fell on me as a by-product. The course was more plodding than heroic: I did not strive valiantly against doubters but took incremental steps studded with a few intuitive leaps."
"My most persistent memory of stand-up is of my mouth being in the present and my mind being in the future: the mouth speaking the line, the body delivering the gesture, while the mind looks back, observing, analyzing, judging, worrying, and then deciding when and what to say next."
