Every time a newsletter goes out, I get wonderful emails from readers telling me how much they enjoy it. At the same time, I get a spate of unsubscribes. Often, the subs go up by the same number they go down. It’s frustrating. Because of the positive emails, I know there’s an audience for what I’m doing here. Can you help me reach more of it? Can you post a link to this newsletter in your social media? Share with other maker enthusiasts? Thanks so much for your help.
Let’s Talk About Clamps
In this “Ask Adam Savage” segment on Tested, Adam is asked about shop clamps. This leads to a typically-Adam thoughtful and wise deep dive into the many uses and types of clamps: c-clamps, bar clamps, vice grips, quick-grip clamps, welding clamps, jeweler’s clamp, bench vises, lever clamps, kant twist clamps, and last but not least, spring clamps. One great tip takeaway: Don’t ever buy one clamp. Buy at least two, and if you can afford it, but 4 or more.
I subscribe to FineScale Modeler magazine, even though I’m not really a scale modeler. I was as a teen and still like looking at what people are up to in that hobby. Mainly, I look for modeling tips that I can apply to my hobby of miniature painting and tabletop game modeling. Here’s a great case in point. You can use a scribbing compass to cut circles in styrene. You just have to be patient, make multiple passes, and finish up with a hobby knife if the piece is thick or stubborn.
A Collection of Razor Rules of Thumb
A “razor” is a rule of thumb that simplifies decision making. Here’s a collection of the sharpest razors gathered by Sahil Bloom and posted on Twitter.
The Feynman Razor Complexity and jargon are used to mask a lack of deep understanding. If you can’t explain it to a 5-year-old, you don’t really understand it. If someone uses a lot of complexity and jargon to explain something, they probably don’t understand it.
The Luck Razor When choosing between two paths, choose the path that has a larger luck surface area. Your actions put you in a position where luck is more likely to strike. It’s hard to get lucky watching TV at home—it’s easy to get lucky when you’re engaging and learning.
New Column: Ask Gar
If you have questions about tools, things you might have read here in the past, resources you’re in search of, email me.
Reader Rick Griggs asks: “I need to buy headmounted lighted magnifying glasses. I don’t know what to look for, and thought you’d reviewed (or linked to a review) of these in a distant past newsletter that I could read/watch to learn more, but I can’t find anything. If you have done this, please point me to which one.”
Hey Rick,
I’m not sure it was in the newsletter. I know I talked about these in my old tips column on Make:. The one I have is shown above. It costs under $10 on Amazon! For my purposes (miniature painting), it’s great. It has two lenses that offer 1.5X magnification each and a third monocle lens at 7X magnification, providing intensities at multiples of 1.5, 3, 8.5, and 10. The light angle is adjustable in two directions and the light pack can even be removed from the headband for use elsewhere. A lot of features for under ten bones!

My old pal, Steven Roberts, asks about racks to hold Stanley organizing cases:
“Do you know of any quick-turn kits/products to handles stacks of Stanleys? Of course the solution is obvious, but I have so many projects that I don’t want to do it. If someone has made one, or published a good repurposing of something like a bakers rack or other off-the-shelf (heh, so to speak) tool, I’m all ears!
”If you have responses to questioned asked by readers here, let me know.
Regarding the term Minimal Viable Product (MVP). It was coined by Eric Ries in his book The Lean Startup as a way of learning what potential customers found valuable before spending a lot of time and money building something that people didn’t want to buy. Unfortunately, I think Reis did not do a very good job of naming this because it really doesn’t mean a stripped down product. In his world, it refers to anything that you can quickly learn from. Some examples could be a fake landing page which actually does nothing but gather insight about whether customers click on the link or not. I know of a company that used wire frames drawn on paper as an MVP to learn what people would pay for. Yes, it can be a stripped down version of an actual product, but in most cases, if you’re doing that before you’ve learned what people want to pay for, it’s overkill.

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.
Beal clean grip liquid chalk:Recommended to me by a more experienced lifter when I started weight training in 2010. Every time I’ve forgotten it since, lifting has felt like trying to hold onto the bar with soapy hands. One bottle lasts for years.
Any A4 spiral notebook: I’ve used an A4 spiral notebook to plan my weeks since 2014. One notebook per year, one page per week. Each page follows the same structure: a numbered list of ten projects or focus areas for the week. Not tasks, but the things that will compete for my attention. Seeing all ten on a single page gives me a realistic sense of capacity. If something is tied to a specific day, I simply write the weekday—like “Tue”—on that line. I sometimes add small circles next to an item to indicate how many pomodoros I want to spend on it. It’s a simple, manual system. It doesn’t help me do more—it helps me decide what actually matters this week.
Oral-B iO electric toothbrush: The difference in feel between a manual toothbrush and an electric one is real. The difference between a standard electric toothbrush and the Oral-B iO feels just as big. You notice it immediately when you run your tongue over your teeth. Once you’ve gotten used to that level of clean, going back—when traveling without it—always feels noticeably worse.

Readwise (and Reader): I’ve used Readwise since 2020. I’m currently on a +1,700-day review streak, with over 30,500 highlights—mostly from Kindle Paperwhite/Kindle app and Reader. What keeps me coming back isn’t the streak, but the habit it supports. Highlights resurface when I’ve forgotten them, often at exactly the right time. Readwise Reader has also become my default place for PDFs and (long-form) articles. It’s the best app I’ve found for turning things I read into things I actually remember.
A personalized Todoist setup based on Tiago Forte’s video series: I’ve adapted my Todoist system around Tiago Forte’s approach to managing projects and commitments (from his excellent video series). Instead of treating Todoist as a task dump, my setup helps me distinguish between what I’m committed to and everything else. I find this framework far more useful than a generic inbox-to-zero workflow—the structure gives direction, not just an empty inbox. The method has become the backbone of how I actually work with Todoist.https://www.youtube-nocookie.com/embed/cg-29pZUFcs?rel=0&autoplay=0&showinfo=0&enablejsapi=0

Herbie, the bottleneck
From The Goal by Eliyahu Goldratt. In the story of Herbie, the slowest boy in a hiking group determines the pace of the entire line. Even if everyone else walks faster, overall throughput cannot exceed the speed of the bottleneck.
The insight is simple: system performance is governed by its constraints, not by the individual speed of its fastest parts.
