Show notes: 



This year I worked on a photography project, doing a lot of close-up photographs of objects. This kind of photography is about 5% photography technique, 5% lighting, and 90% cleaning. While compressed gas dusters work fairly well, there is a sense in which they just move dust around. And, more conventional tools like microfiber cloths tend to leave their own debris. I ended up using a type of cleaning gel or “universal dust cleaner” as they brand it. It is basically the same stuff that is sold as “slime” in toy stores, but wrapped up in corporate IT-department friendly packages. Nominally, you can clean things like keyboards with it. But as a tool to trap and remove dust for photography, it’s remarkably good.



This is a classic 6 inch/150 mm steel ruler, or “machinist’s scale”. It’s marked with inches on one side — subdivided into tenths and hundredths — and millimeters on the other. Mitutoyo is one of the most respected names in precision measurement, and this particular ruler is simply a joy to use. I use other scales of this size, but this one is just a little thicker and has eight perfectly square sides. It has a better surface finish (precision ground with satin chrome plating), and has markings that are just a little finer, and easier to read. It feels like they could charge $100 for the same thing and get away with it, but it’s about $15, and worth every penny.



Mitee-Bite is a manufacturer of workholding equipment for machining. They make a wide range of extremely specialized tools for holding chunks of metal — sometimes really weirdly shaped chunks of metal — in place while CNC machines do their thing. I’ve found their little catalog to be one of my most frequent references when designing setups for machining, but also in just designing parts in the first place. There are so many clever tricks that they use to build strong mechanical structures, and there’s a lot to learn from them.



Ask a whole lot of telescope lovers what the best “first” telescope is and you’ll probably hear about the Orion XT8, well and above any other suggestion. It’s a Dobsonian, meaning that it’s nearly instant to plop down on a sidewalk and start observing. It’s big enough to let you see all kinds of amazing things, and upgradeable, if you get into it.

2021 Holiday Gift Guide: Camille’s Picks

Gift suggestions from Cool Tools' alum

The editors of Cool Tools have curated a number of gift suggestions selected from our website, newsletters, videos, and podcasts. This week: former web manager Camille revisits some of her favorite Cool Tools and shares a few more.

I’ve been wearing these Russell Sheepskin-Lined Moccasins for 10 years, and it shows. Shortly after Wrye Martin’s original review ran, I ordered a pair of Russell boots for hiking, and although they are also wonderful (and still in great shape), it’s the slippers that I’ve worn nearly every day all these years. They are warm, perfectly cushioned by the shearling, tolerate a little walking around in the backyard, and thanks to their custom construction, they actually fit my feet, which have a two-size differential. I keep flirting with the idea of buying something off-the-shelf in town, but I just need to make peace with the 3-5 months production time and do it.

Blip Blox Synth For Kids has been a great addition to our instrument collection since the kids were very young. Its brightly colored knobs are highly grabbable and the whole thing is easy to wipe down. Ours has certainly taken a number of falls from toddler heights. All this means the kids can tweedle to their hearts’ content and dad can play along on his more delicate synths. Can do way more than my demo which illustrates the low barrier to entry.  Here’s documentation – the “Mapped” doc and “What they do” docs are helpful beginner references.


Kinderfeets Kinderboard ($89-$99) is an open-ended balance toy that can be used as a slide, boat, hill, bed, catapult, sled, etc etc. Santa delivered ours a couple years ago, and our now 5yo and 8yo still enjoy playing with it. This is the bamboo version.


The Sonos system has been mentioned a couple times on Cool Tools (by Louis Rossetto, Wayne Ruffner), and recently Jim Louderback shared about the Move speaker on the Cool Tools podcast. Our household is also a big fan. In addition to the One and Move, we also really enjoy the Beam ($449), which is a great compliment to our minimalist frame TV, and Symfonisk ($149), a more affordable speaker without voice activation which is a good fit in our youngest kid’s room

Making a Simple Storage Case Rack

Gareth's Tips, Tools, and Shop Tales - Issue #103

What was your favorite tool this year? Why? It doesn’t have to be a new tool just one that comes to mind when asked this question. Send me your answers (with a pic, if possible). I want to do a round-up of readers favorites for 2021. I’ll pick one of the respondents and send them a copy of my tips book.


Making a Simple Storage Case Rack
On the Shop Hacks FB group, member Riley Schatz posted a pic of his simple solution for a rack to hold his plastic storage cases. Many of us have these plastic cases and there are numerous projects online and on YouTube for building more elaborate racks. This is the simplest to date, little more than some scrap 2x4s and plywood hung below a workbench.

Review: Amazon Removable Compartment Professional Organizers
Speaking of multi-compartment storage cases, Amazon just recently (I think) began offering cases under their Amazon Basics brand. Being something of a collector of these cases, I decided to get one and try it out. I got the smaller 15-compartment case (8.3″ L x 13.3″ W x 2.4″ H). They also carry a 19-compartment case (16.5 x 13.2 x 2.4). The 15 case is $17.80, the 19 case is $20. The case I got is much small than the Stanley, Harbor Freight, and other cases that I have (which are closer to the 19-compartment case). I purposely went for the smaller case because I want to use it to house game components and didn’t need the larger size. In terms of features, the removable trays are a must-have for me. They have a nice compliment of small, medium, and large trays. In terms of quality, these cases are on par with the Harbor Freight ones. Like the Harbor Freight cases, they are made of heavy-duty polypropylene. The latches are the weak spot on the both brands, with the Amazon ones being nearly identical to the HF closures. Even with medium use, I’ve had the latches on two HF cases fail. The Amazon cases are comparable, but HF still has them beat on price. Their (full-size) 20-bin case is only $10 (as low as $8 on sale) and their deeper 8-bin case is $15 (as low as $11). The only reason to recommend the Amazon cases is if you want the smaller size.

Using Wire Ferrules

Here’s an electronic component I’ve never even heard of: the wire ferrule. In this brief Collin’s Lab Notes, Collin Cunningham introduces us to these stranded wire-end connectors and how to use them.

Flat Panel Speakers Made from Foamboard
This is more of a project recommendation than a shop tip. On the AmplifyDIY channel, they build these cheap (a few hundred bucks) and easy-to-make flat panel speakers using little more than insulation foamboard, a pair of exciters, and a mini power amp. They results are very impressive. Also: Be sure to check out the follow-up video. In it, he tests out different shapes, panel treatments, adding a second exciter to each panel, and other tweaks.

Why You Need a Vise in Your Workshop
In this Essential Craftsman video, Scott explains the virtues of a vise and why you need one in your workshop. In our new house, there’s a big gaping hole in the wooden workbench in the garage where the vise appears to have been unceremoniously ripped out. I’ve already spotted a sweet small bench vise with an anvil at a local antique store. I’m looking forward to buying and restoring it soon.

Making a Spray Can Shaker
In a recent Adam Savage video, he extolled the virtues of a drill-powered paint mixer. The one he linked to on Amazon can be found here. You can also easily make your own.

How to Tune Up a Cheap Chisel
In this videoAnne of All Trades shows how to properly sharpen chisels, especially how you can sharpen cheap ones and get them closer in sharpness to more expensive tools. I especially appreciate that she demonstrates how to hold and use your body to get the right angle and pressure on the blade as you sharpen

Switchplate Identifiers
We just moved into a house that has these crazy 4-switch light and fan panels in the bathrooms. Unlabeled, a newbie can do a lot of speculative switching before finding the one you want. So, not surprisingly, these 3D printed switchplate symbols have caught my eye. As soon as I get my 3D printer set up, I might be printing some of these.

Shop Talk
In the response to my “Put the Dang Tools Back!” in the last issue, reader John M writes:

“I’ve been working on the “put the dang tools back” for years now. Coming up on three years since the last shop move, the problem that looms the largest is that there is no “back” to put things until you create one. The last move went from 3,000 sf to 1,600 sf, so it’s been tricky. Making the job harder is the need to be functional over the need to be organized. Yes, taking the time to organize will make the work easier, but that job needs to get finished NOW so we can pay the rent! Needless to say, instead of spending my limited time pursuing personal projects, I tend to spend it cleaning and organizing. Somewhat satisfying, but not as much as other projects.“


Also in response to “Put the Dang Tools Back!,” Cool Tools reader LarryA2010 writes:

“Good advice. Easier said than done. I have projects at varying stages, piles of tools and materials, and other stuff strewn about my workshop and I hate putting things back. I do keep some tools and materials organized though. I have a worktable made from a solid core door on top of two wood filing cabinets which hold folders of sandpaper and other useful items. Most-used tools are in a simple tool caddy on the floor. Two old bureaus hold sets of wrenches and other large tools. Plastic totes hold unfinished projects. Solvent cans are in a row on the floor next to my chair with a strap wrench on top to tighten them so they don’t evaporate. I still have tools and small materials covering much of my table, and tools and materials spread all over the floor. I can’t get myself to organize them. One thing I do have that I keep in order is this really useful Alvin, Spin-O-Tray, Rotating Desktop Organizer on top of the desk. It makes it easy to replace often-used small tools after I use them.”

“The best magazine being published in the 21st century” — Drew Friedman


I started painting a few years ago and since then I’ve found tools for my painting that I hope will be helpful for you if you’re interested in painting. I like to stand while I work and use my work counter for writing and painting. When painting, I mix the paints on a piece of freezer paper with its corners held down by painter’s tape near the edge of the counter near my easel. I store my paint and smaller canvases on the shelving under the counter. My workroom has a number of large windows that let in plenty of natural light.

Gamblin makes excellent oil paints in Portland, Oregon. Besides a great color selection of paints that are easy to mix, I like their focus on creating non-toxic paints. I use their website for paint information such as this helpful page, but their paints as of now are only available through art stores. I purchase mine at Utrecht. Gamblin also makes an odorless mineral spirit called Gamsol for your oil paint cleaning needs.

Rosemary & Co. is a wonderful company that handmakes paint brushes in Yorkshire, England and is run by Rosemary and her daughter. With excellent customer service and a user friendly website, they make it easy to order from the UK. I like their free physical catalog where the photos of each brush head is the actual brush head size. They make all types of brushes using real animal hair or ones that are completely synthetic, plus they sell palette knives and brush holders (featured in the photo).

Artist Brand Canvas make attractive, sturdy canvases in Los Angeles. They have all kinds of sizes and are reasonably priced. Having one of their canvases, a Rosemary & Co. brush and some Gamblin paint is an inspiration for your painting!

And don’t forget your color wheel! I like to keep mine handy. You can purchase it from many stores online, but they have a website. They even make a special color wheel for gardeners, and all their wheels are made in the USA.

Eyeglass holder for shirts with no pocket

Eyeloop is a simple metal loop and magnet that allows you to hang your readers or other glasses off of a small loop so they are always at the ready. Instead of fumbling with a collar or buttonhole to hold the glasses. There are various designs, but I like just the simple basic one. It allows me to always know where my readers are when I am working around the house and it’s easy to pop on and off different shirts.
