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.
When I first realized that my housemates were serious about me using a push mower to cut our yard, I was a little skeptical. Eventually I was won over by the environmental benefits and the sense of accomplishment that I received from using a “reel mower.” The first mower we purchased is literally called the “Prison reel mower” and I wouldn’t recommend it. The Brill Luxus 38 Reel Mower on the other hand is a sweet piece of engineering. It is very light at 17 pounds, weather resistant, and has variable height ranges. It feels good in your hands and seems very well designed. Now that I use it, I wouldn’t even consider buying a gas or electric powered mower for an average size yard. But let me warn you, using a manual mower is physically much harder, takes more time, and is very difficult if not impossible with tall grass (which means regular mowing). Whether you choose to look at that as an environmentally friendly and money-saving workout or a punishment is up to you. — Patrick Chen
My lawn mowing days are long over, but if I was still able-bodied enough, I would definitely spring for one of these. As Kevin Kelly points out in the comments, dull blades on push mowers is what makes them a chore to use, and sharpening is hard (or expensive). The Brill mower is allegedly designed in such a way that the manufacturer claims it only needs a sharpen every eight years.
TOYS! Tiny Rulers Rule!
One of my favorite moments of tool-love discovery is when I find a tool that’s an instant aha and I want to smack my forehead for going so long without understanding its indispensable utility. Enter the diminutive 6” ruler. I love rulers and I have all sorts of them: printer’s ruler, desk rulers, carpenter’s square, machinist’s ruler, sewing gauge, etc. But they’re all at least a foot long. It had never occurred to me to get a 6” ruler until I saw a hobby modeler using one and they pointed out something I understood all too well: Your workbench gets covered in stuff, then you go to, say cut some polystyrene, and you have to move everything out of the way so your 12” or 15” ruler can lay flat on the cutting mat. For small-scale work, the 6-incher solves that beautifully. And, for under $6, you get three. I now have one at each of my workstations.
Extension Cord and Power Strip No-Nos
It’s coming upon that time of the year when the unknowing play electrical-cord fire roulette with their extension cords and power strips. CNet has a service journalism piece on 7 devices to keep far away from extension cords and power strips. I assume Gar’s Tips & Tools readers know these basic extension cord fire hazard scenarios already (space heaters, toaster ovens, microwaves, etc.). But just in case…
Here’s the TL;DR:
“…The big thing to keep in mind regarding extension cords is to never use them with ‘any appliances whatsoever.’ He also said that your average home extension cords [and by that I assume he means 16- and 14-guage cords -ed] shouldn’t be used for anything above 15 amps (1,800 watts), regardless of where or how the device operates. With power strips and surge protectors, those should only be paired with electronics.”
Which Adhesive is Best for HDPE Plastic
https://youtu.be/JJzfSqfxRS4
In this video, Hacks By Dad tests 13 different tapes, glues, and epoxies to determine which is the stronger bond between two HDPE bottle caps. The caps were glued together and then subjected to a weight-pulling jig. The top three winners were JB KwikWeld (at 20.2 lbs of holding power), Gorilla 5-min Epoxy (25.8 lbs.), and… the winner is: Dap Rapid Rise (at 27.6 lbs). For mounting tape, Duck brand hung on for an impressive 19.8 lbs. before failure.
How to Repair Broken Plastic
https://youtu.be/GQ9ZcmB620c
In more plastic makery news: I have always been intrigued by plastic hot staple welding. In this Chris Notap video, he gives one a go on a split recycling can. If you’re gonna repair anything plastic, your recycling can seems top o’ the list. We have a split in out municipal recycling bin. Maybe I’ll try to hot staple weld it rather than turning it in for a new one. The kit he used is cheap, at $35, and there are ones under $20. Since this is not a high-use tool for most of us, a cheap tool is probably good enough.
