Mississippian Hillar Bergman is known, first and foremost, as a musician—he plays the fiddle. His YouTube channel, as catinnahat, has several videos describing his wonderful “apocalyptech” potter’s wheel, and demonstrating his skillful use thereof. It’s just an old wheel and tire, mounted on an oak stump with a pair of pipe flanges and a short nipple, and spun up to speed with a tire iron stuck through the holes in the hub.
We have covered septuagenarian Palestine, TX, resident Pat Delany’s DIY multimachine, which is mostly built from recycled auto parts, before. Following on the success of that design, Pat has branched out, researching and promulgating three more simple build-it-yourself tool designs: A treadle-powered electrical generator, a simple compound lever drill press, and—most interesting to me—a lathe made from cast concrete and aligned with wedges sawn flush after the concrete has set up. Engineering for Change has a good overview of the story and the available online resources. [Thanks, Jake!]
An easy, useful, inexpensive, and delightful improvisation from model-maker and Instructables user WiredWebbo101, who needed a handy tool to sand primer in some hard-to-reach places on his models. So he modified a disposable electric toothbrush by flattening and pointing the head and attaching a dart-shaped piece of sandpaper. Wonderful!
This attachment mounts in place of your router’s factory baseplate and is used for cutting circular disks from, or boring circular holes in, sheet stock. It pivots about a small pin rotating in a blind hole drilled in the center of the stock to be cut. This one is based on a design from Bill Hylton’s excellent book “Router Magic.”
We have covered a lot of bike-related content over the years, and a lot of bike-repair-related content. Trouble is, we don’t have a separate repairs-only category, so assembling this round-up required manual cherry-picking from the many pages of our Bicycle category archive. I then picked my ten favorites, tabulated the pageviews for each, and counted the days since it was posted, and divided to get an average-traffic-per-day figure for each post. So this is probably my most scientifically-organized Top 10 to date. I hope you enjoy it. Happy Friday!
This Instructable from Jared Foster doesn’t just show you how to make his cool persistence-of-vision business card. It takes you through the construction of a circulating etch tank, the modification of a laminating machine to make a stencil applicator, the assembly of a controller to turn a toaster into a reflow oven, and the cobbling-together of a vacuum pickup tool for SMT components. And then you get some practice using all that cool stuff making a POV business card. It even comes with obligatory American Psycho allusions.
Clever tip from reader Ryan O’Horo. [Thanks, Ryan!]
