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.
Whether you’re a hiker, biker, backpacker, camper, naturalist or simply someone who’s ever been caught in the rain, you’ll treasure these classic all-weather notebooks. The cover is Polydura and the pages are made with a substrate, giving the paper a wax-y feel. The effect: water beads off them, meaning no pulpy mess and no bummer over any lost thoughts or data. They are not a new invention by any means. Back in the 1920s, they were developed for Pacific Northwest loggers. These days, the manufacturer makes both bound and spiral bound books in an impressive array of sizes and types (e.g birding!). I keep a pocket-size, 24-page, staple bound mini-book in the small pack I take cycling and hiking. In the event of a downpour, all my ah-ha moments are safe. If you plan to be in really harsh conditions and want to go the extra mile, you might try one of their all-weather pens. Note: I have not used them — a pencil or standard ballpoint does the trick for me. —Steven Leckart
Before I start a new painting, I usually draw what I want in Adobe Illustrator, and then transfer a printout of that drawing to canvas or board to paint. I’ve tried opaque projectors, but the image is faint (at least on the el-cheapo projector I use) and I don’t really have room to set it up. I’ve also tried using a piece of paper that I’ve rubbed pencil or charcoal on, but that produces a blurry line.
Like an idiot, it wasn’t until recently that I considered the possibility that there might be a transfer paper for artists. Of course, there is one. It’s called Saral Wax-Free Transfer Paper, and it works like a dream. It comes in five different colors, but I can get away with blue and white. It leaves a clear, thin line that erases easily and doesn’t mess up the color of the paint I use. I’m already hooked on it for life.
If you send a self-addressed, stamped envelope to Saral, they’ll send you free samples in all five colors. — Mark Frauenfelder
Anyone doing technical or design work has burned through reams of graph paper. I’m a designer, and I use Whitelines to do technical drawings in accurate scale, which are then turned into 3-D models and die tooling diagrams. Whitelines is the best graph paper I have ever worked with.
The concept is simple and powerful. Ordinary graph paper is paper with a graph of lines printed on it in a light color, often blue or gray. Whitelines is paper with a very light gray grid of squares printed on it. The graph is unprinted, hence, white lines.
This is genius. Pen strokes, and even pencil, are startlingly clear against the background. The distracting visual noise of a printed graph is gone entirely, while retaining the precision and ability to see scale, which is graph paper’s reason for being.
I’ve been using Whitelines extensively for the past few months, mostly for technical drafting on the MakerBeam project, an open source metal building kit like Meccano for the Arduino set. The grid is 0.5 centimeter pitch, perfect for working on a metric standard. With ordinary graph paper, pencil lines are close in color weight to the lines themselves. When scanning pencil marks on ordinary graph paper, the pencil lines often vanish completely. With Whitelines, I can scan a pencil sketch, if I’m satisfied with it, without having to go back over it with pen.
Available in A4, A5 and pocket sizes, as tablets, spiral bound, perfect and hardbound, both lined and graph. Better graph paper makes better drawings, and this is genuinely better graph paper. — Sam Putman
OK, so I wanted to sit down and workout a grand plan for my new garden, so I figure a pencil and some graph paper is the way forward.
Just finding some simple 2mm graph paper with 1cm semi bold and 2 cm bold turned out to be a near impossible task. Then I discovered the Graph Paper PDF Generator at incompetech.com .
It does plain paper, lined paper, multi width, hexagonal, even semi-bisected trapezoid! All completely customizable. And it’s free! — Mark Coffey
Ever have an idea in the shower and have no way to record it…and then it’s lost forever? I use a “Dive Slate”, a small (~4″x6″ ) sheet of sturdy white plastic with a plain old fashioned golf pencil attached. They’re cheap (around $5-$8), available on the net at various dive shops, fit nicely behind the soap holder or hung in the shower and work well; they’re meant to be written on underwater by divers, so unless you shower under Niagara Falls, your thought will be captured until you erase it. — Vincent Crisci
