Loosen Plier Joints with Valve Grinding Compound

Formula for silky pliers

I don’t know how good pliers are made (rivet joints and box joints) so that they don’t seize up immediately. One extra whack of the big factory hammer seems to me like it’d wreck most efforts to make a good pair of pliers, or almost anything with a similar joint. They usually seem to get it close enough though, so good on ‘em.

Too many pliers at the stores are packaged so you can’t really get a good feel for the condition of a tool’s joint before you walk away (with it or without). I’ve got a few pliers with silky joints, and they’re an absolute pleasure to use. I’ve had (past tense!) some with sorta sticky joints that were more than a little irritating to use. I’ve had a few that were pretty well stuck, and so got zero use.
Breaking them in just didn’t seem to be worth the effort.

Bought another German pair around Christmas, mail order, good sale price. Too sticky to use. Dang. So I checked the solution machine at YouTube and got this:

Some Permatex compound ($5), some WD40, not a whole lot of work, and Bang! All my previously irritating pliers are silky! I’ve even picked up some truly rusty old abused pliers at Flea Markets and now they’re silky too. Last weekend I found a pair of Kraeuter pliers (a model last made in 1921) and, after some restoration work, they may be better than new. The process is cheap, only a little bit messy and easy to clean up. Rescue those pliers! Oh, and that new German pair (from NWS) is now terrific!

Pizza Stand

More room on your table for group feasts

I’ll bet almost everyone’s “used” one of these wire stands ($8) at a pizza joint. Nothing amazing there. Of that “almost everyone,” how many have also been jammed up on a family table during a holiday feast? This thing ever pop up in your head then as an obvious solution? Nope, me too. Until recently. These are pretty cheap, lots of versions available, simple to store, and everyone already knows what it’s for. Then you’ll have more room for the drinks that make get-togethers more interesting…

Pin Locks Enamel Pin Keepers

Keeps your favorite enamel pins from falling off your clothes

If you wear enamel pins, particularly pins that have any kind of sentimental value to you, I highly recommend a set of pin locks.  ($6 for 12) I picked up a set of ten pin locks similar to these at Disneyland last year for $9.99 in the Oswald the Lucky Rabbit store near the entrance to Disney’s California Adventure, because I had already lost one Tomorrowland enamel pin from a shirt while I was at the parks a couple of years ago and another (also Tomorrowland!) from the backpack I carry during my daily commute via train and foot and because the other pins I have on the bag constantly needed to be pushed back onto the simple tension-style pin backs that enamel pins typically come with.

The Disney pins currently come with a rubber Mickey-shaped pin back, but they still essentially work using tension. The way this tool works is that there is a metal sleeve that you put over the sharp end of the pin with a threaded hole in the side and a small set screw that screws into that hole. The set screw is tightened down using the included hex wrench, and then your pin is not going anywhere. I have used these for about six months now and they show no sign of becoming loose. The only drawback is that the locks stick out a little bit further than the typical pin backs that come with the pins, so if you’re wearing a pin on a shirt with nothing underneath the lock itself might be uncomfortable, but not much more so than the pin back itself. One caution is that the set screws are also really tiny so you need to be careful – I dropped one at work and it disappeared forever into the dark carpet.

Smartphone shortcuts/Laura Olin/Specialty pillows

Recomendo: issue no. 143

Sign up here to get Recomendo a week early in your inbox.

Smartphone shortcuts
The ever-helpful David Pogue has a fantastic list of smartphone shortcuts I had no idea were possible. They save lots of taps. I programmed my phone to set up macros ( a series of steps into one step) initiated by a voice command, like “Hush Now” which silences your phone until you leave your current location.  — KK

Newsletter follow
Digital strategist Laura Olin has a newsletter with interesting miscellany that contains links to useful tips, thought-provoking quotations, and links to articles and videos. If you like Recomendo, you will like Laura’s newsletter. — MF

Wedge pillow for sleeping
When my sinuses are acting up, the thing that gives me the most relief is using a wedge pillow like this one. It keeps my head elevated and prevents post-nasal drip while I sleep. I always wake up better rested without a blocked nose or phlegm. Here’s an article that answers the question, “Do specialty pillows really work?”. — CD

Visual follow
A lovely stream to follow on Twitter: 100 views of Tokyo. Each vignette is drawn in a colorful manga style. (Should be an Instagram stream, but is not.) — KK

Push reel lawnmower
I have always used gasoline lawn mowers. I recently got a 5-blade push mower and am amazed at how smoothly it operates. It’s very easy to push, and the blades whir like a fan, neatly cutting the grass. It’s a pleasure to use. — MF

Conquering the to-do list
Two things have kept my to-do list on track lately. The first is this notebook previously recommended by Mark in issue 80. I bought 4 to stock up for the year. And the second is committing to the habit of asking myself the four questions from this Ted article. The most effectual being, “What’s the most important thing I can do today that would make tomorrow better?” and “Should I do this task now or can I do it later?” — CD

Show notes:

Flexible Silicone Neon-like LED Strip (How-to video) ($14)
It’s called Flexible Silicone Neon-like LED Strip. I’ve seen it in a few different places. The first place I came across it was on the Adafruit site, and they still have kind of the best selection of color options for this. It’s LED strip that takes 12 volts, which is a little unusual. It is the most realistically neon alternative I’ve come across. This really is geared towards people who want to make a neon-style sign or replacement signage without all the mess and hassles of really using glass neon tube. … You can bend it in half. It’s very flexible, you can cut it. Actually, John Park, who you’ve had on the show, he did a whole guide on using this stuff to make a neon-style sign in his workshop. His is cooler than mine. His will animate. He’s got like a thunderbolt going through a robot or something like that, and they kind of alternate. You can cut it to length, just like addressable LED strip, and to get exactly the length you want, or also to do, to bridge between different sections of it. It’s useful, it’s not cheap though. Adafruit has a meter of it for about 14 bucks. I’m also starting to see it now on Amazon. Actually. I just bought a batch of it today on Amazon to see if this other brand is going to be as nice a color as what Adafruit is able to provide. You can do all the same tricks you would do with a regular neon sign. You can duck it behind another color of the same style of strip, or you can black out sections. Or you can really use it the same way a sign maker would use neon, but it’s not delicate. It’s weatherproof. The way I found to mount mine, and I haven’t really seen anyone else do this before, but it was the first thing that occurred to me, was to get a piece of plywood and use a router to just route out a shape using like, maybe it’s like a quarter-inch routing bit, just like a flat bit, just to dig in enough of a groove that I could fit the LED strip into the shape that I put in with the router. Then run a cable out the back and plug it in.

Evil Mad Scientist WaterColorBot ($295) + Inkscape
The other thing I’ve been playing a lot with recently is the WaterColor Bot from Evil Mad Scientist. This is a CNC plotter that will draw out designs onto a piece of paper, but it can use a set of watercolors to make the drawings, which is a really unusual and funky and playful way to do it. I’ve been kind of playing around with plotter art recently, and there’s kind of upswell of a plotter art enthusiasts who are kind of getting together on Twitter and sharing their designs. I wanted to kind of join that, but I wanted to do it in an interesting way. This has been a fun device to start playing around with. They have software. There’s two different flavors of it. You can use the, kind of the really user-friendly software, which is called RoboPaint, which is a program that they developed that’s on GitHub and there’s a lot of support for. They’ve deliberately made that as kind of kid-friendly and classroom-friendly as possible. With that, you can load in a drawing and then you could have it automatically try to do its best guess at separating out the colors of your drawing. It will take solid elements of your drawing and apply like a hatch fill to it. It’s a little slow, or maybe my computer’s a little slow, but so it takes a little patience but the results have been always pretty fun to get at the end of the result. There’s a little unpredictability there, but as someone who’s just kind of getting started with it, even the worst drawing I make on this thing still has like a fun, childlike quality to it that I can’t be mad at. There’s also a set of Inkscape plugins that you can load up, and with that you can get pretty advanced with having different layers of an Inkscape SVG file, covered, different colors and different aspects of the design you want to print out. Inkscape is an open source, kind of like an Adobe Illustrator alternative, but it’s a pretty popular option for converting files and working with SVG type Vector files.

Third on the list kind of dovetails with the WaterColorBot. It’s a site I just learned about last week called Turtletoy.net. It’s a repository of people’s shared kind of plotter illustration graphics. I think of it almost like a Thingiverse for plotter art. Like if you get a plotter, just like if you got a 3D printer, you go and plug it in your wall, and you get it warmed up and ready to go, you’re like, “Okay. Now what do I print?” You go to Thingiverse, and you could download a file and you could 3D print it, and you could get something going right off the bat. Turtletoy is kind of like that for plotters, and there’s, each of these like illustrations you can find on the site. You can click on it. You have both the illustration on the left, and then you have the code that generated the illustration on the right. You can go in and you can tweak the code. You can make the illustration a little bigger. You can make the algorithm that generates the art do something a little stranger. Then you can save the output as an SVG file that you can send over to pretty much any plotter, or also like a laser cutter or a vinyl cutter.

Kai Chan Cardboard Cutter ($10)
This one is kind of a call back to my obsession with these Canary style cardboard cutter knives. I may have talked about one last time I was on the show, but I’ve gone through a few of them. There’s the yellow-handled one. There’s a green-handled one that I found last year that’s retractable. Now recently, there’s this pink handled one that has a little nub of a knife that sticks out. Maybe about an inch out from the handle. About as much as you’d think like a utility knife would extend. It’s really just made to, I think, open up boxes. It’s just long enough that you can rip open a box. It’s the kind of knife that should, anytime someone signs up for Amazon Prime, this should come in your first package … It’s not sharp, you’re not going to stab anyone with this thing. It’s deliberately made to be a little blunt at the top so that you’re not cutting into the thing that’s in the box. The sides of this knife are serrated in this very fine way that just loves to go through packing tape or the paper-based Amazon type of packing tape. It can cut through cardboard really easily. I love grabbing this thing. When a box arrives at my doorstep, I know that I’ve got just the right little tool to kind of get through it, and make quick work of opening it up.

Also mentioned:

The home for all my stuff is MakerProjectLab.com. Through that, you can find the videos, the show notes, project links and the newsletter. The newsletter is really like the one-stop place where people can get the Maker Update information every week.

Seiko SKX007 Automatic Watch

Powers automatically with the movement of your arm

I have had this wristwatch ($248) for about two years. It self-winds (i.e. automatic), accepts nato straps, looks nice, is waterproof (to 200M as it is a true dive watch), and rugged. I haven’t broken it. The benefit of a mechanical watch is that it runs as long as you have it on your wrist as it self-winds. A mechanical watch is a great reminder of time. To me, time is important, it is all we have and we don’t know how much we have.

Not only does it look nice and allow me to keep track of my day, it serves as a reminder that “Time is tight.”

Mechanical wristwatches can be incredibly expensive. This one can be had for less than $250, sometimes under $200. It is known as one of the best value automatic watches on the market and a great introduction to horology. There are plenty of aftermarket modification pieces if you want to modify your watch into something more personal. The watch is widely available on Amazon and elsewhere on the internet and in brick and mortar stores.
