Force Conversion Calculators
On Digi-Key’s website, they have a set of calculators for converting between various units of physical force (newtons, gram-force, metric ton-force, and others). So, the next time you need to covert between Sthène and Poundal…
Torture-Testing Bench Vises
Bench vises are one of those common tools where people rave about the cheap ones available at Harbor Freight. I’ve always wondered how true this was. So, seeing this Project Farm video, I was anxious to know how the Freight would fare. Todd tested the following brands: Heuer, Ridgid, Yost, Wilton, Baileigh, Irwin, Forward, Central Forge, Olympia, Myoyay. Vises were tested for clamp load, durability from impact, anvil durability, and clamp load failure point. This is one of the few Project Farm videos I’ve seen where Todd pushed the tool to complete failure.
Sure enough, the $69 (at time of testing) Harbor Freight vise (Central Forge) performed amazingly well. Not surprisingly, the $500 (at time of testing) Heuer was best overall. Now that I see this testing, I’m definitely going to grab a Harbor Freight vise. When we moved to California last year, I left my two vises on the east coast and I’ve been missing having one (beyond my Dremel hobby vise).
The Basics of Photochemical Machining for Precise Parts
In this Applied Science video, Ben provides a nice and thorough introduction to photoetching small, precise metal parts, aka photochemical machining. The process is involved, not really for beginners, and this is a work-in-progress video. But, because there aren’t any vendors out there (that I’m aware of) providing this service for small-batch photochemical machining, this video is a way in if you need to consider creating such small, precision metal parts on your own.
Bringing a Rusted Cast Iron Skillet Back from the Dead
Over on Boing Boing, Mark Frauenfelder shared this video on one of the many processes (basically they’re all the same with some variation) for reviving a completely rusty cast iron skillet. Years ago, I decided to revive the 3 very rusty skillets I had in the bottom of my pots and pans cabinet. I watched several videos and followed a similar process. It was so satisfying to bring these decades-old kitchen tools back to life.
The Existential Pleasures of Restoration and Repair
Good as new!
Speaking of kitchen tools, my wife’s handheld mixer died recently. I heard it seize up as she was making something downstairs. We could’ve just bought a new one (this thing is ancient), but I really wanted to fix it, especially as she told me of its lineage. This is the first and only mixer she’s ever had. Every holiday feast was made with this mixer. She raised her kids on this mixer. Her sister gave it to her. As I like to say, tools always come with stories, and this one has great stories. I took it to my workbench, took it apart, and had a look. I quickly discover that the wormgear that transfers the motor’s spin to the beater gears was frozen. Some WD-40 and and few gentle twists with the needle nose and it was working again. Easy! The beater ejector had long ago broken, so I fixed that, too. The mixer was filled with decades of dust, batter gunk, and thickened oil. I took everything apart, cleaned it, inside and out, and put it all back together. This process was an act of love, for my wife, and also for the stories this mixer tells. And now, will continue to tell.

Watching the Stumpy Nubs vid on oscillating tools, I thought about getting mine out and seeing if it could solve some of my “learning issues” with 3D printing. Not only did my Dremel Multi-Max MM40 fit with a Diablo HCS flexible adhesive scraping blade do beautiful work cutting away support material from PLA prints, but I’m pretty sure it will work to get those stubborn PETG prints to release from the PEI print surfaces I’ve got on all my printers. To my surprise, at a shallow angle of attack (e.g., < ~30 degrees) the oscillating adhesive blade doesn’t seem harmful to the print surface, despite its keen front edge, and it wiggles under really stuck PETG. As pointed out in the Stumpy Nubs video, the oscillating blade can be grabbed without danger. I think it might become my new favorite way of releasing sticky 3D prints so that I don’t damage the surfaces of my printers.

Reader Kristian Reinhart (who was the winner of last year’s holiday tips challenge) sent a batch of new tips. Here are a few:
* The quickest non-chemical way I’ve found to clean up the surface of 3D prints (especially flats or edges on FDM prints) is using a snap-off blade and scraping over the surface. Much less hassle than sandpaper. Card scrapers, especially small ones, also work great, and depending on their shape and the shape of the print, shape do so far better than the snap-off blades, but they’re not as ubiquitously available and require maintenance.
* When lending tools or other things, I take a picture and edit it to write down the name of the recipient, then I store those pictures in a separate folder on my phone. That way, I always know exactly what I lent out to whom, and from the date of the picture, when.

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.
The Nesco Food Dehydrator is a simple, affordable, and well-built tool for drying foods quickly and thoroughly. Though not an every-day-use item for most people, it becomes absolutely essential when it is needed.
I recently went on a weekend trip hunting for morels and returned with far more than I could eat. Luckily, this dehydrator made short work of the excess. The stackable trays easily fit 60 whole small morels and many of the larger ones which I’d cut in half. Altogether, I fit about three pounds of mushrooms in fivetrays.
Like the previously reviewed Excalibur Food Dehydrator, the Nesco model has a temperature control, fan, and heating unit. The Nesco’s heating unit is built into the top (cheaper models heat bottom-up) that sits atop the stack of trays and blows air through a central column allowing for better distribution and airflow throughout.
I used a temperature of 110F when drying morels, and left them to dry over night for about 8 hours. Since any moisture can lead to a ruined batch, I made sure to let them dry out for a little longer than necessary. They were perfectly dried the next morning, and ready for storage in an airtight container.
While I have mainly used this model for mushrooms, the large trays and variable temperature dial (95-160F) allows for a wide range of dried foods to be made. This particular model is also expandable to 12 trays if you need to dry a truly astonishing amount of food.
The Nesco, when compared with the Excalibur, has the benefit of being nearly $125 dollars cheaper combined with a smaller (though expandable) footprint, a relatively-quiet fan, and similarly adjustable temperature. — JC
I have experience with both the Excalibur and the more recently-reviewed Nesco, a smaller and less expensive dehydrator. The Excalibur is a superior product if you are a heavy user and tend to be drying large batches of produce at once. It has quite a bit more capacity due to the design (no center hole and square racks make a big difference). The horizontal airflow system does dry large batches more uniformly. Although you can add racks to the Nesco, it dries less efficiently, and once you add in the cost of extra racks you are approaching the same price as the Excalibur.
Having said that, the price on the Nesco has really dropped and the top-down heater/blower is a nice upgrade over the older bottom-fan models. Heck, you could almost get three of them for the same price as an Excalibur, although that would take up a lot of storage space and use more energy to power 3 units. — Oliver Hulland
I’ve been using this 9-tray dehydrator once or twice a week for the last three years to make dried fruit, veggies, jerky, dog treats, and dried bread crumbs. Other uses include re-crisping crackers, cookies, and chips, and thoroughly drying wet photographs and flowers.
Overall, this is truly the most flexible dehydrator I’ve found. The thermostat is adjustable (85-145F), so you can customize your dehydrating. The removable trays allow you to experiment with sizes, quantities and varieties of foods sorted by temperature range. If you group shorter-term items by tray, you just remove those trays first, then keep the remaining items/trays inside a bit longer.
Other units heat unevenly from the bottom, require you to manually rotate trays, and — in the case of cheaper units — don’t let you control the temperature. Along with a thermostat, the Excalibur has a fan that distributes heat more evenly; it also features a timer, so it will automatically turn off at a desired time whether you’re around or not.
All of the dehydrators I’ve used generate noise (I now use my Ronco and Home Essentials models exclusively for making dog treats). Since the Excalibur isn’t quiet, I keep it in our craft room. It’s very easy to clean. I enjoy not throwing out spoiled food. We always have healthy snack alternatives for us and our grandkids — and they enjoy contributing to the process as much as they eating the rewards. Ever since we moved to a property with grapevines, they’ve helped us make copious amounts of raisins.
Tips:
1) To make fruit yogurt leathers or work with items high in moisture content, you’ll need ParaFlexx non-stick drying sheets. Excalibur provides a pretty good guide on how to work with different foods.
2) If you buy direct from the manufacturer, it may be slightly more expensive, but I understand they’ll guarantee the unit for 10 years; otherwise, you can purchase a 10-year extended warranty. — Chris Lewis

Affordable, freeze-dried goods
Dehydrated Food In Bulk
Backpackers, canoeists, campers and scouts have two basic ways to stock their food supply: classic prepackaged freeze-dried meals or building your own menu. Commercial freeze-dried camping food is expensive, limits menus choices and is hit or miss in the flavor department. Most of us have learned to shop carefully at the grocery store and put together a fairly lightweight, nutritious menu for weekend trips. But add a couple of people and extend the trip for two or three days and grocery store options get a bit heavy. Supplementing with bulk freeze dried or dehydrated food expands the choices and cuts down the packed weight while developing a tasty, nutritious menu without blowing the budget. If you are planning an extended trip, I highly recommend assembling your menu with these two suppliers in mind. — Clarke Green
I’ve organized six days of food for 18 people in two crews for a canoe trip (18 meals, 324 servings), which would have been impossible — or just plain expensive — had I not ordered Honeyville’s goods. They offer a wide variety of vegetables, fruits and other foodstuffs in bulk (#10 tin cans, and cases even). While a single-serving package of freeze-dried strawberries (.06 oz.) from Mountain House is $3.00 ($50.00 an ounce!), Honeyville’s #10 can of freeze-dried strawberries (6 oz.) costs just $17.00 ($2.83 an ounce). They will ship an order of any size anywhere in the continental U.S. for under five dollars — just a little more than a gallon of gas!
Soups, vegetables, fruits and textured vegetable protein (i.e. soy-based meat substitute) in large AND smaller quantities so you customize freeze-dried meals for long, big, short and small trips. They also offer a Backpacking Kit, a pre-selected assortment of dried foods that will make a variety of dishes. Don’t miss these two very helpful PDF files: Using Dehydrated Products and a Serving Size Chart.
