A Master Class in Prototype Making
In response to John Baglio’s search for a series of prototyping videos he’d run across, Talon Chandler immediately responded with:
“He’s probably talking aboutDan Gelbart. Dan is a local legend among engineers in Vancouver, BC. He founded Creo, a printing technology company that sold to Kodak circa 2005, and several other companies including Kardium, a growing healthcare company. I’ve had the pleasure of meeting Dan once (I interned at Kardium close to 10 years ago), although I haven’t had the pleasure of visiting his extraordinary shop.”
Others also messaged me and told stories about the impact of Dan’s videos on them. They are amazing. I haven’t found a treasure trove like this since discovering TubalCain/MrPete222 some 15 years ago. Anyone interested in precision machining, prototyping, water jet cutting, and a wealth of general machine shop wisdom should check out this channel.
Expanding the Usefulness of 1-2-3 Blocks with a Hardware Kit
I’ve long been a fan of 1-2-3 blocks and always have them handy when doing a host of different projects. They’re great for quick measuring, aligning, holding parts together for gluing/ fastening, as shop weights, and countless other applications. One of the features that few people outside of machining use are the holes drilled into the blocks. These are not just there to keep the overall weight down. They are threaded and non-threaded holes designed for attaching the blocks in various configurations (such as for making right-angle or T-shaped jigs).
In this Stumpy Nubs video, James introduces a clever little hardware kit for easily attaching blocks – and attaching them with nothing proud of the surfaces. As he points out, you can source these screws and through-hole fasteners yourself, but why not support the guy who came up with the idea for this kit? That guy, Mike Taylor, sells a kit of 6 hex-head screws, sized for 1″, 2″, and 3″ attachment, 4 threaded through-hole dowels, a hex key, and a slotted driver head – all housed in a handy little plastic box. I immediately bought a kit (only $10) and I love it. Mike also makes really high-quality blocks at an affordable price ($20/pair). I snagged a pair of those, too. It always feels good to support a maker small business.
Using Finger Pressure to Match Hex Head to Wrench
On the Twitter account of software engineer Roach, he posted this clever way of matching a hex head to a hex wrench. Pressing your finger into the head will leave a dimple that you can use to size the appropriate wrench.
A Prompt Book for Better AI Art Generation
If you’ve spent any time on social media lately, you’ve likely seen some of your acquaintances go down the rabbit hole of artificial intelligence image generators like Midjourney, DALL-E, and Google’s Imagen. These programs take descriptions that you feed them and return AI- generated art interpretations of that input. It’s very addictive and fun and has huge disruptive potential. My wife Angela and I were joking a few weeks ago that in the future, art will be nothing more than the ability to input the most fulsome description of what you want. And then, just a few days later, Recomendo shared a link to The Prompt Book, a free PDF of instructions, examples, and tips for refining your input commands. It’s directed at the DALL-E program, but its ideas can be applied to any of these art generators. In the future, art will be incantation.
Making a Shop Paper Roll Dispenser
Poking around on the ‘Tubes, I came across a series of DIY videos, called Try, that Kevin Kelly did on Cool Tools in 2020-21. How did I miss these? Here’s one on building a kraft paper roll cutter for your shop and a really charming one about the sign that he made for the Kelly compound in Pacifica, CA.I hope he gets inspired to do more of these.
Maker Slang
Jargon, slang, and tech terms from the many realms of making.
FEP – (Fluorinated Ethylene Propylene) A tough, no-stick plastic material commonly found in the bottoms of resin vat 3D printers. Its translucence allows the light source beneath it to shine through the vat, curing the resin onto the build plate.
Holidays – A term used by professional painters and gilders/gold leafers to refer to gaps in coverage. It derives from the joke that a painter must have taken some time off, a little holiday, by not covering an area they should have. [Hat tip to gilder Michael Kramer]
Minimal viable product – A phrase used by Italian maker and product developer, Giaco Whatever. In creating a product, you want to pare your idea down to its minimum possible components. See also: KISS (keep it simple, stupid)
Real job – A project that’s a series of tasks and challenges that imply significant time and effort – as opposed to a task which can be quickly accomplished. “That’s a real job. I need to set aside an afternoon for that.”
Resilient idiot – A self-deprecating admission that sometimes knowledge and skills seemingly won’t stick, not matter how hard you try and learn them. Coined by Donald Bell. Not to be confused with Andy Birkey’s similar: actual moron.
“This is a very common tool for locksmiths when dealing with vehicle lockouts. The inflatable pry bar can generally create enough space for the locksmith to drop a loop down to grab the lock pin from the interior of the door frame and gain entry without having to damage or possibly ruin the actual lockset on the car door. But don’t underestimate their power. I used one on an old car when I locked my keys in and it bent the door to the point that it never fully aligned to the door frame gasket again.”

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.
At first sight it’s a nice-looking puffy jacket. Then someone picks up said puffy jacket and throws it at you. You put your hand out ready to catch a pound or so of duck-filled garment and then – nothing. Not what you expected. It’ as though a helium balloon just brushed against your hand. It’s thick and puffy and warm, but it doesn’t weigh anything.
And so began my love affair with the Montbell Ex Light Jacket. Not to be confused with its heavier cousin, the Montbell UL Jacket, the Ex Light weighs in at a scant 5.7 oz for a medium. Don’t expect frills such as pockets or hemmed waists, or the insulation and more durable exterior of a thicker down coat.
I wore this jacket whenever I had a chance on the Wonderland Trail. Rest stops, camp, heck I even slept in it on most nights. It’s a perfect complement to my lightweight summer bag when things get a little chilly at night.
Granted, I’ve spent more time in this jacket off the mountain at this point. It’s so snug, so cozy that I’ve been living in it for most of the winter. It replaces my Bozeman Cocoon Vest, and for 0.4 oz more it packs a whole lot more warmth. The downside is that I’m more vulnerable to rain as the Cocoon was synthetic and this is down, but I’ve found it to be a worthwhile tradeoff. —Brett Marl
Normal “breathable” shells have three great failings. The worst is that they’re just not that breathable, especially in rain, and extra-especially for people who carry on high-energy activities when it rains. This is because they’re based on a pored membrane that works by letting water vapour go from dryer to wetter air, so when the air outside is wet you’re stuck with living with your own sweat. Their two other failings are that repairing rips with a needle is disastrous, because water flows through the holes the needle makes in the membrane, and that getting dry once you’re soaked – whether by your own sweat or a fall in a river – takes forever. Softshells try to get around some of these problems, but at the cost of letting in moderate to heavy rain.
A company that has found the answer is Paramo with their “Directional” shell fabrics. Instead of using a membrane they use a “pump liner” that sucks water away from the inside of their shells. So sweat is still expelled in the rain, needle holes don’t matter because water trying to enter via them is pumped back, and if you get soaked under your shell when you fall out of your kayak your baselayers will dry out faster with your Paramo on, sucking water away, than if you took it off.
In other good news: Paramo is rustle free, completely windproof (it’s a popular choice of Antarctic exploration teams), is easily washed and re-proofed in a washing machine, and the average hard-used shell seems to last about a decade.
The downside of Paramo shells has been that they combine a shell with a midlayer, making them too warm for many people except in winter, and slightly bulky to carry. However the latest Paramo Velez Light has fixed this problem with lighter insulation and excellent venting. You simply put it on a over a baselayer and work the venting (and roll up the sleeves – something you can’t comfortably do with a normal shell) as needed – the shell stays on all day. Because sweat transport and venting are so good this works in all but summer weather. The Velez Light also has an exceptionally good hood that keeps goggles and spectacles dry in the rain but provides more than adequate side vision even for cycling in traffic.
The bad news is that although discussed excitedly on ultra light-weight hiking lists from time to time, Paramo doesn’t seem to be stocked widely – if at all – in the US. However, ordering from the UK is hardly the adventure it was before the invention of the steamship and wireless telegraph.
How good is Paramo? Good enough so that I can crank a cyclocross bike at maximum speed cross country in heavy rain and ice cold wind and my torso is as warm and dry as it would be if I was cycling on a summer day wearing only a wicking tee shirt. In short, ***astoundingly*** good. — Jonathan Coupe
Filson’s gear is made in Washington state and is superior to almost all of the winter/outdoor gear I’ve used. They are a bit spendy but spectacularly well made, and they wear like iron. I imagine my Filson Mackinaw will be handed down to my daughter and then to her children before its usefulness has departed. The woolen gear is quiet in the woods, keeps you warm even if damp or wet, and smells just fine to boot. Thumbs up. — John Coates
Having to work outside in really tough conditions is bad enough, but many times worse if you’re cold too.
I found RefrigiWear suits years ago. They’re made for workers in blast freezers, so they’re tough, not super expensive and come in lots of sizes. My whole crew got these suits and they kept us fully functional while outside overnight for February-in-Wisconsin telecom projects.
I have no idea what Iditarod racers wear, and I’m pretty sure these won’t have the right cache for the ski set, but for working people these suits help you get the job done in the cold and won’t drain the piggy bank. — Wayne Ruffner
Tips:
A bit of research online shows that 70% isopropyl alcohol in a 2:1 ratio with water seems to be the optimal solution to deice windows (if you have it on hand, methanol is recommended as well), and that it won’t hurt your car’s paint-job(although it might remove some wax). — Oliver Hulland
I have a small wet/dry vac that I use as a substitute for renting a rug cleaner to spot clean my rugs and furniture. Use soap and water in a spray bottle or just pour it out of a glass on the spot. Rub it in with a brush or your fingers and thensuck it up with the wet/dry vac. Rinse the spot with plain water two or three times the same way. It works great. I’ve done this to get juice off of my car seats as well.— Stephen Foss
Two-inch diameter concave mirror from Edmund Scientific magnifies your face when you look into it, and the shorter the focal length, the more magnification you perceive. While this mirror is intended no doubt for high school studentsconducting optics experiments, I use it to examine my own eyes. Why, you ask? Because when I am traveling, there is a small but tangible chance that I may get a particle of foreign matter in one of my eyes at a time when there is no one around to see it and remove it. (I once paid $200 to an emergency room, merely for removal of a tiny piece of soot adhering to the underside of an eyelid.) I don’t use contact lenses, but I imagine this problem is more acute for people who do. The downside of transporting the mirror is that it is fragile, but I have managed to avoid breaking mine for a couple of years now, and recently I was glad that I had itwhen I was in Florida on my own, everything was shut down because of a hurricane…and I got something in my eye. — Charles Platt
I had a white board with old writing on it – I tried Windex, alcohol, etc, to little avail, then my girlfriend suggested using a whiteboard marker – they are full of the correct solvent! Just color over what you want to erase and wipe it away.Doh! — David Spargur
