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.
What do an extension cord, a corkscrew, a French press, an ice tray, and a large drinking glass have in common? They’re all items I’ve bought and left behind when the furnished apartment I rented while traveling was lacking what I needed. Yeah, I could have made a request with the owner, and have done that when the kitchen was truly barren, but I’ve learned that “Don’t sweat the small stuff” is a good short-term apartment rule of thumb. Most items I bought in some kind of discount store or the local market, always an added adventure. The coffee press came from a Malaysian IKEA ($8), another interesting cross-cultural experience. One friend who used to be nomadic would even buy an air fryer and leave it if he was in a place for two or three months, but I’m not sure I would go that far…
International Money Back-ups
My ATM card never came back out of the machine when I used it in Tashkent, two years after an airport ATM ate a version of the same card in the Republic of Georgia. The second instance had a happy ending thanks to a phone call from my tour guide and a trip to the bank’s HQ. I was never really sweating it though because I had backups. I have three cards that don’t charge an ATM fee and reimburse the local fee as well (to a point with the last one). They’re tied to cash accounts at Fidelity, Schwab, and my biz bank Novo. I generally keep at least one in a separate place/bag from the others. Plus a PayPal card, a Wise one (don’t love it), and whatever my wife is carrying. Overkill? Maybe, but I never pay a fee to get my money this way and I know I’ll always have access.
Airports Where Connections Are a Pain
While you see lots of lists for best airports (we highlighted one for the USA last week) and worst airports, this article Kevin Kelly sent me that originally ran in the Washington Post focuses on one aspect: long and confusing connections. A few frequent travelers I know are quoted in it and I can say that all four airports I try hard to avoid for connections are featured: Miami, JFK, Heathrow, and Paris. Two of them mentioned, Frankfurt and Denver, have been 50/50 for me. I hate a lot of things about Istanbul’s airport, but getting to your gate is fairly straightforward there.
